‘And if you’re going to generate a mouse for the first time you don’t want a mutant that’s kind of wimpy.’ Meanwhile, at MIT in Boston, Tyler Jacks – renowned for creating one of the two first p53 knock-out mice in 1992 – was on the same track. His lab was busy generating two different mouse models that mimicked LFS – one with the same point mutation as Lozano’s mice, corresponding to human R175H, and another corresponding to R273H. The two groups published their findings in the same edition of Cell in December 2004. What distinguished their mouse models from others designed to test the activity of mutant p53 was that here the gene was being switched on naturally in response to signals from the cell’s environment. In most other models, the gene was switched on artificially by the researchers – and herein lay the big sticking point.

See­nobel_prizes/­medicine/­laureates/­1997 Other key references were two papers, published simultaneously in the same journal, Cell, Volume 119, 2004, by Tyler Jacks and Gigi Lozano and their colleagues: ‘Mutant p53 Gain of Function in Two Mouse Models of Li-Fraumeni Syndrome’ by Kenneth P Olive et al. (847–860) and ‘Gain of Function of a p53 Hot Spot Mutation in a Mouse Model of Li-Fraumeni Syndrome’ by Gene A Lang et al. (861–872). See also ‘Mutant p53: one name, many proteins’ by William A. Freed-Pastor and Carol Prives, in Genes and Development, 2012, Volume 26, 1268–86. Chapter 19: Cancer and Ageing – a Balancing Act? The epigraph from John Maddox, editor emeritus of Nature, comes from his introduction to The Eighth Day of Creation by Horace Freeland Judson, page xii.

Research, he realised, was what he wanted to do, and after graduating from Wisconsin he managed to get into MIT, the hothouse of bright minds and exciting science, where Mario Capecchi had discovered his calling some 30 years earlier. At MIT Lowe met Tyler Jacks, a young researcher who had picked up Capecchi and colleagues’ new technology with enthusiasm and was busy creating transgenic mice of all kinds to investigate cancer-related genes. Jacks had made some knock-out mice in which various tumour suppressors had been deleted and he was asking the simple and obvious question: do the animals get cancer? He had a mouse model with p53 knocked out, but he had been beaten to it in his experiments by another scientist who had been investigating the same question, so his p53 knock-out mice were sitting around with not much to do. Jacks was happy to let Lowe suggest alternative experiments with them. Lowe was already fascinated by apoptosis. He had done some work with cell cultures, watching it happen, to his great surprise, in response to oncogene activity, and he was not sure what role, if any, p53 was playing.

Besides the shortcomings of mice to mirror dementia, studies also found that screening drugs in mice was far from ideal. In 2010 it was estimated that 90 per cent of drugs based on mouse models fail in clinical trials.5 The reason: unlike mice found in the wild, lab mice are inbred, and therefore don’t capture the huge genetic variation seen in people. And although their genome is very similar to ours, the way they use it–how they switch genes on and off–is very different. As the Harvard physician H. Shaw Warren put it, if one ‘tried to understand a station wagon by studying a motorcycle, one would learn something about wheels and spark plugs but have no idea about steering wheels, airbags, and sunroofs, and the larger picture would be substantially missed’.6 Indeed, one study found that only 12 per cent of the genetic changes seen in mouse models of inflammatory disorders mimicked those seen in humans7–providing ‘a sobering reminder’, wrote an editor for Nature Methods, ‘of what most thoughtful biologists already know: your biological conclusions are really only as good as the methods that get you there’.8 But iPS cell modelling, too, had some troubling caveats.

Epigenetics Revolution: How Modern Biology Is Rewriting Our Understanding of Genetics, Disease and Inheritance by Nessa Carey

Secondly, the studies also show us that a particular class of epigenetic modification is not in itself good or bad. It’s where the modification happens that matters. In the rat model, the decreased DNA methylation of the cortisol receptor gene is a ‘good’ thing. It leads to increased production of this receptor, and a general dampening down of the stress response. In the mouse model, the decreased DNA methylation of the arginine vasopressin gene is a ‘bad’ thing. It leads to increased expression of this hormone and a stimulation of the stress response. The decreased DNA methylation of the arginine vasopressin gene in the mouse model occurred through a different route to the one used in the rat hippocampus to activate the cortisol receptor gene. In the mouse studies, separation from the mother triggered activity of the neurons in the hypothalamus. This set off a signalling cascade that affected the MeCP2 protein.

Take a small scraping of skin cells from our patient, whom we shall call Freddy. Grow these cells in culture until we have enough to work with (this is pretty easy). Use the four Yamanaka factors to create a large number of iPS cells, treat these in the lab to turn them into beta cells and put them back into the patient. There will be no immune rejection because Freddy will just be receiving Freddy cells. Recently, researchers have shown they can do exactly this in mouse models of diabetes4. It won’t be that simple of course. There are a whole range of technological hurdles to overcome, not least the fact that one of the four Yamanaka factors, c-Myc, is known to promote cancer. But in the few years since that key publication in Cell, substantial progress has been made in improving the technology so that it is moving ever closer to the clinic. It’s possible to make human iPS cells pretty much as easily as mouse ones and you don’t always need to use c-Myc5.

One of the most debilitating aspects of Rett syndrome is the profound mental retardation that is an almost universal symptom. Nobody knew if it would be possible to reverse a neurodevelopmental problem such as mental retardation once it had become established, but the general feeling about this wasn’t optimistic. Adrian Bird remains a major figure in our story. In 2007 he published an astonishing paper in Science, in which he and his colleagues showed that Rett syndrome could be reversed, in a mouse model of the disease. Adrian Bird and his colleagues created a cloned strain of mice in which the Mecp2 gene was inactivated. They used the types of technologies pioneered by Rudolf Jaenisch. These mice developed severe neurological symptoms, and as adults they exhibited hardly any normal mouse activities. If you put a normal mouse in the middle of a big white box, it will almost immediately begin to explore its surroundings.

A Crack in Creation: Gene Editing and the Unthinkable Power to Control Evolution by Jennifer A. Doudna, Samuel H. Sternberg

Before CRISPR, the arsenal of tools to study cancer-causing mutations was rather limited: scientists could detect and diagnose mutations in biopsies taken from patients, and they could study a small number of discrete mutations in mouse models. But now that researchers have a way to precisely replicate cancer-causing mutations—single ones, or many at a time—in a fraction of the time that was previously required and at a fraction of the cost, cancer research is poised to explode. Instead of painstakingly selecting the correctly mutated cells (an ordeal with one-in-a-million efficiencies) or breeding the desired mouse models over numerous generations (requiring years of time), scientists can use CRISPR to efficiently introduce mutations in a single pass. This capability is allowing scientists to better understand the exact genetic factors that cause cells to stop responding to the signals that normally regulate their growth.

One strain of AAV might be best suited to deliver CRISPR to cells of the liver, while another might work best in the central nervous system, the lungs, the eyes, or the cardiac and skeletal muscles. It’s in muscles where we’ve seen one of the earliest and most dramatic demonstrations that CRISPR can ameliorate the ravaging effects of genetic disease in vivo. While the technique was demonstrated in a mouse model, there’s every reason to think that it will be effective in human subjects as well—not least because the genetic disease it was used to treat is, sadly, prevalent in our species. The fatal muscle-wasting disease known as Duchenne muscular dystrophy (DMD) is the most common type of muscular dystrophy in the world, inherited by roughly 1 in every 3,600 male babies. DMD patients have no symptoms at birth, but the disease appears—and progresses with devastating speed—beginning around age four.

For instance, using a version of CRISPR programmed to edit a different gene and a version of AAV better suited to target the liver, a team at MIT used gene editing to cure mice of a genetic mutation that causes a condition known as tyrosinemia. In humans, the disease can cause an accumulation of toxic metabolites and extensive liver damage; if untreated, patients usually die before age ten. In the mouse model, however, CRISPR repaired the damaged gene and reversed the course of the disease. AAV has also delivered CRISPR into the brains of adult mice, into their lungs, and into retinal cells in their eyes, all of which may eventually translate into therapies to treat genetic disorders like Huntington’s disease, cystic fibrosis, and congenital blindness. Indeed, the first gene therapy drug approved for commercial use in the Western world uses an AAV vector, and it’s possible that the first CRISPR-based gene-editing drug relying on in vivo delivery will do the same.

Lastly, prior sensitization to an antigen through extraintestinal routes affects the development of a hypersensitivity response. Sensitization to peanut protein was demonstrated by application of skin preparations containing peanut oil to inflamed skin in children [37]. Similar results were obtained by Hsieh’s group in epicutaneous sensitized mice to the egg protein OVA [38]. The dose of antigen administered is also critical to the form of oral tolerance generated. In mouse models, low doses of antigen appear to activate regulatory/suppressor T-cells [39,40]. There are an increasing number of such cells identified, of both CD4 and CD8 lineages. Th3 cells were the initial regulatory/suppressor cells described in oral tolerance [40–42]. These cells appear to be activated in the PP and secrete transforming growth factor-β (TGFβ). This cytokine plays a dual role in mucosal immunity; it is a potent suppressor of T- and B-cell responses while promoting the production of IgA (it is the IgA switch factor) [34,43–45].

This cytokine plays a dual role in mucosal immunity; it is a potent suppressor of T- and B-cell responses while promoting the production of IgA (it is the IgA switch factor) [34,43–45]. TGF-β is the most potent immunosuppressive cytokine defined and its activities are broad and non-specific. A recent investigation of the adaptive immune response to cholera toxin B subunit and macrophage-activating lipopeptide-2 in mouse models lacking the TGF-βR in B-cells (TGFβRII-B) demonstrated undetectable levels of antigen-specific IgA-secreting cells, serum IgA, and secretory IgA (SIgA) [46]. These results demonstrate the critical role of TGF-βR in antigen-driven stimulation of SIgA responses in vivo. The production of TGF-β by Th3 cells elicited by low-dose antigen administration helps explain an associated phenomenon of oral tolerance, bystander suppression.

As mentioned earlier, oral tolerance is antigen specific, but if a second antigen is co-administered systemically with the tolerogen, suppression of T- and B-cell responses to that antigen will occur as well. The participation of other regulatory T-cells in oral tolerance is less well defined. Tr1 cells produce interleukin (IL)-10 and appear to be involved in the suppression of graft-versus-host disease (GVHD) and colitis in mouse models, but their activation during oral antigen administration has not been as clearcut [47–49]. Frossard et al. demonstrated increased antigen induced IL-10 producing cells in PP from tolerant mice after β-lactoglobulin feeding but not in anaphylactic mice, suggesting that reduced IL-10 production in PPs may support food allergies [50]. There is some evidence for the activation of CD4⫹CD25⫹ regulatory T-cells during oral tolerance induction protocols but the nature of their role in the process is still under investigation [51–54].

Although technically possible, the project had to remain speculative for ethical reasons. The first step was to acquire some genetic material containing Elvis's DNA, achieved when Barhad managed to purchase one of Elvis's hairs on eBay.' The next step would be to have the DNA sequenced to identify behavioral traits such as sociability, athletic performance, and susceptibility to addiction and obesity. Barhad then identified a company that creates mouse models for scientific experiments and would in theory be able to produce a transgenic Elvis mouse using the genetic material he provided. Next, Barhad built a tower of custom designed environments based on ones used in laboratories to test traits in genetically modified mice. Each compartment simulated key biographical moments in Elvis's life. By going through the process of designing an Elvis mouse based on current technologies, Barhad highlighted the absurdity of thinking of clones as anything more than a material reproduction of another living thing.

It is an important space, a place where the future can be debated and discussed before it happens so that, at least in theory, the most desirable futures can be aimed for and the least desirable avoided. Although it is not possible for designers to build actual products using biotechnology yet, we should not let that stop us from getting involved; we can still create functional fictions that help us explore the kind of biotechnological world we wish to live in. Koby Barhad, All That 1 Am: From a Speck of Hair to Elvis Presley's Mouse Model, 2012. © Koby Barhad. The universe of possible worlds is constantly expanding and diversifying thanks to the incessant world-constructing activity of human minds and hands. Literary fiction is probably the most active experimental laboratory of the world-constructing enterprise.' Although design usually references sculpture and painting for material, formal and graphic inspiration, and more recently the social sciences for protocols on working with and studying people-if we are interested in shifting design's focus from designing for how the world is now to designing for how things could be-we will need to turn to speculative culture and what Lubom r Dolezel has called an "experimental laboratory of the world-constructing enterprise."

Junk DNA: A Journey Through the Dark Matter of the Genome by Nessa Carey

This leads to increased production of the beta-amyloid that is essential for the formation of the plaques.31 It’s been reported that the levels of this long non-coding RNA are increased in the brains of patients with Alzheimer’s disease, but it’s difficult to interpret these data. This could just be a consequence of increased expression in that region generally. Remember the earlier analogy – the more you chop up logs, the more sawdust you create. But researchers managed to find a way of specifically decreasing the expression of just the long non-coding RNA in a mouse model which frequently develops Alzheimer’s pathology. The knockdown of the long non-coding RNA resulted in decreased BACE1 protein and fewer beta-amyloid plaques. This supports the idea that the long non-coding RNA may play a causative role in this devastating disease.32 It’s not just the central nervous system that can be influenced by long non-coding RNAs. Neuropathic pain is a condition in which the sufferer feels pain, even when there is no physical stimulus.

It may be a combination of both these factors, plus others that we have not yet identified. But where we have this uncertainty – parent and child with the same genetic change but different symptoms – it’s vital to develop additional lines of evidence to support any hypothesis about the impact of the variant base. The researchers who identified the C to T change in the enhancer did exactly this, by testing the effect of this change in a mouse model. They showed that when the C was present, this stretch of junk DNA acted as an enhancer of morphogen expression. But when the C was replaced by a T the region no longer acted as an enhancer, and levels of the morphogen never reached the critical levels in the brain. Morphogens and the pancreas The morphogen that is implicated in the development of extra digits or in the various forms of holoprosencephaly isn’t the only example of a human condition caused by a change in a regulatory region of DNA.

Researchers used these mice and applied genetic techniques to dial down the expression of one of the key messenger RNAs that would normally be controlled by the Fragile X protein. When they did this, the scientists detected marked improvements in the animals. Spatial memory was better and the mice behaved appropriately around other mice. They were also less susceptible to seizures than the standard Fragile X mouse models. These symptomatic improvements were consistent with underlying changes that the scientists detected in the brains of the animals.14 Neurons in normal brains have little mushroom-shaped spines that are characteristic of strong, mature connections. The neurons of humans and mice with Fragile X syndrome have fewer of these, and a larger number of long, spindly, immature connections. After the genetic treatment, there were more mushrooms and fewer noodles.

It was found to abrogate tumour growth in BRAF mutant xenografts derived from various tumour types.203 RAS and BRAF inhibition has been shown to result in re-differentiation with resultant re-expression of thyroid-specific genes, including the NIS gene.204,205 MAPK inhibition may not only inhibit tumour growth, but also restore radioactive iodine avidity in a significant proportion of de-differentiated/ advanced thyroid cancers. In addition to MAPK signalling, several studies have assessed the feasibility of PI3K/AKT inhibition and p53 targeting in thyroid cancer. Furuya et al. demonstrated that LY294002, a potent PI3K inhibitor, reduced tumour cell proliferation and blocked metastatic spread of thyroid tumours in a mouse model of follicular thyroid cancer.206 Treatment of thyroid cancer cells with the AKT inhibitor KP372-1 also suppressed cell proliferation and induced apoptosis in thyroid cancer cells.207 Other promising agents include histone deacetylase inhibitors and PPARγ expression ligands.208–214 It is hoped that these efforts will substantially improve the outcome of patients with aggressive, refractory, metastatic disease.

It mirrors something we see in human adults—women tend to have a higher percentage of fat mass in their bodies than men. “A second example is that if we give the mouse a heart attack, the animals with two X chromosomes do worse than the animals with one X chromosome,” he adds. “And the third example in the mouse model is with multiple sclerosis, where we induced a multiple sclerosis–like disease in the mouse, and the animals that are XX do worse than the animals that are XY.” Multiple sclerosis in humans, being an autoimmune disease, affects more women than men. Their take-home message is that many of the sex differences we see in health are rooted deep down in genetics. “The study of mouse models has provided convincing evidence that cells with two X chromosomes are intrinsically different from those with one X chromosome. Sex differences caused by the number of X chromosomes can have a profound effect on disease,” Arnold and his colleagues wrote in their paper about the experiment, published in 2016 in the journal Philosophical Transactions of the Royal Society of London B.

Thus we envision a connection matrix in which associated with each neuronal bar code are a few additional bits of information specifying the neuron’s position in the circuit and its identity. A cheap and rapid method for deciphering the wiring diagram of a neural circuit or of an entire organism would have a profound impact on neuroscience research. Many neuropsychiatric diseases such as autism and schizophrenia are thought to result from disrupted neuronal connectivity, but identifying the disruptions even in mouse models is a major challenge given current technology. More fundamentally, knowledge of the neuronal wiring diagram would provide a foundation for understanding neuronal function and development in the same way that knowing the complete genomic sequence provides the starting point for much of modern biological research in the postgenomic era. BOINCing may not solve the brain, but it promises to bring us one step closer.

Indeed, there has been much interest in the demonstration of protein-coding differences between FOXP2 in humans and chimpanzees (as well as more recent work on human-Neanderthal sequence differences elsewhere in this gene). Again, functional experiments are playing a central part in helping scientists to assess the biological relevance of the sequence changes, using the same systems (cell lines, mouse models, and such) as those used for investigating the mutations that cause disorder. Even so, if we want to comprehensively join the dots between genes and human cognition, we cannot only depend on growing cells in the laboratory or making genetically modified animals. In recent years a new weapon has been added to the armory, one that could be powerful for making links to the human brain but that has to be wielded with care.

A 2010 study on postmenopausal breast cancer patients receiving adjuvant endocrine therapy showed that those with estrogen-and progesterone-receptor-positive cancers who had a high dietary intake of soy had a lower risk of recurrence.16 The herb Pueraria mirifica has actually been found to stop the growth of breast cells in vitro.17 WHY SOY IS SAFE FOR BREAST TISSUE A study in mice that showed increased mammary tumors when the mice were exposed to Prevastein, an isolated soy isoflavone, received a great deal of media attention in the fall of 2005.18 Obviously many women were concerned, particularly those who eat soy. Here’s what you need to know. Prevastein is a chemically extracted form of purified isoflavones. Soy products made from whole soy do not contain this kind of ingredient. Purified extracts from broccoli, carrots, potatoes, Brussels sprouts, tomatoes, and so on have also been shown to be toxic, depending on how they are made. Mouse models are considered by most experts to be irrelevant to human studies because mice metabolize soy differently from humans (just like dogs can’t eat chocolate). Mice and rats make thousands of times more soy metabolites than humans do. The strain of mice used in this study spontaneously develops breast cancer on any diet (they are bred for this very reason) and the amount of isoflavones administered (130 mg/kg of body weight) in this study would be impossible to consume for a human who is using a product made from whole soy (the average 140-pound woman would have to consume thirty Revival soy shakes every day).

Since different drugs elicited different resistance mechanisms, and produced different toxicities in cancer cells, using drugs in concert dramatically lowered the chance of resistance and increased cell killing. Two drugs were therefore typically better than one, and three drugs better than two. With several drugs and several iterative rounds of chemotherapy in rapid-fire succession, Skipper cured leukemias in his mouse model. For Frei and Freireich, Skipper’s observations had an inevitable, if frightening, conclusion. If human leukemias were like Skipper’s mouse leukemias, then children would need to be treated with a regimen containing not one or two, but multiple drugs. Furthermore, a single treatment would not suffice. “Maximal, intermittent, intensive, up-front” chemotherapy would need to be administered with nearly ruthless, inexorable persistence, dose after dose after dose after dose, pushing the outermost limits of tolerability.

It was a time dedicated to academic thinking, sealed away from the daily whir of labs and clinics in the floors below. It was at these afternoon conferences that Frei began to introduce the idea of megadose combination chemotherapy with autologous marrow support to the fellows and junior faculty. In the fall of 1983, he invited Howard Skipper, the soft-spoken “mouse doctor” who had so deeply influenced Frei’s early work, to speak. Skipper was inching toward higher and higher doses of cytotoxic drugs in his mouse models and spoke enthusiastically about the possibility of curative treatment with these megadose regimens. He was soon after followed by Frank Schabel, another scientist who had demonstrated that combining agents, in doses lethal for the marrow, possessed synergistic effects on mouse tumors. Schabel’s lecture was particularly galvanizing, a “seminal event,” as Peters described it. After the talk, as Frei recalled, the room was abuzz with excitement; Schabel was surrounded by young, eager investigators mesmerized by his ideas.

Meanwhile, the brain’s janitors are at work to sweep out any toxic debris that can gum up its systems if left to build up. Sigrid Veasey is a leading sleep researcher and a professor of medicine at Perelman School of Medicine at the University of Pennsylvania. She’s been working with mice to understand just what happens when the brain doesn’t get its break to conduct certain business. Using her mouse models, she’s found that when the brain is kept alert by neurons firing constantly, these brain cells shed free radicals as a byproduct of making energy.5 Free radicals are rogue molecules that have lost an electron and thus they are highly reactive in the body, damaging healthy cells and tissues. They can potentially be toxic to the brain if they are not swept up. And it turns out that during sleep, these same neurons also produce antioxidants that take care of these free radicals.

Autism Adulthood: Strategies and Insights for a Fulfilling Life by Susan Senator

Bauman is one of the chief pioneering autism researchers in the country, so she certainly believes in the importance of research, but not to the detriment of actual hands-on practice: There’s clinical and bench science research going on now, but how much of this research impacts those living with the disorder now is still elusive. Autism is now recognized as a heterogeneous disorder which can involve multiple organ systems including the brain, and which may have differing causes involving both environmental and genetic factors, resulting in differing neurobiologies and differing clinical presentations. All of this makes the search for effective treatments and interventions challenging. She talked to me a bit about mouse models and chimp studies. Such studies expand our body of useful knowledge, of course. We generally pursue animal studies with the idea that what we learn about biological mechanisms in these animals may one day be translated to help humans. However, occasionally, what we know about human disorders may in fact help animals, as illustrated by Dr. Bauman’s chimp story: “My oldest daughter works at a large city zoo doing research.

The other, encoding one of the two hypocretin receptors, was still in the running. It was looking increasingly likely that the hypocretin system might somehow be involved in narcolepsy. That June, at the annual meeting of the American Academy of Sleep Medicine, Mignot was keeping his suspicions to himself, when a sleep scientist he’d never met cornered him and began to talk of a discovery in his own lab, claiming he had a mouse model of narcolepsy. ‘I see that pretty much every meeting,’ says Mignot, ‘so I rarely get excited.’ But as he began to extricate himself from the conversation, his eye caught the scientist’s name badge: Christopher Sinton, University of Texas, the precise same institution as Yanagisawa, who had described the hypocretins (or orexins, as he called them) the previous year. Mignot’s mind began to race.

We have already developed medicines to disable some of these cytokines, but the task is now to uncover and interfere with the pathways that lead to their release. The anti-cytokine therapies in their many forms are on the pharmacy shelves, but just remember they do not stop the disease, they only treat the symptoms. We must also target the cells that cause destruction in autoimmunity. It was long thought that once the disease was fully established, identifying markers of only “bad” cells would not exist. On the research side, at least in spontaneous mouse models, these “bad” cells can be uniquely identified. Finally, we need a greater understanding of the antigens that provoke autoimmunity to begin. This research is moving forward, albeit more slowly. It was long thought there would only be one antigen per disease, but perhaps the more typical picture is that there are many antigens that trigger disease. The challenge will be to make the agents that target these pathways nontoxic (or at least less toxic).

I’ve seen similar results with low-dose hydroxyurea in several other MCAS patients with otherwise refractory pain syndromes – and I’ve also observed enough overlap between the presentation and behavior of the bone/muscle/joint pain syndrome in MCAS patients and the presentation and behavior of the bone/muscle/joint pain syndrome in sickle cell anemia patients (many of whom demonstrate chronic inflammatory issues and other issues much easier to attribute to mast cell activation than sickle cell anemia) that I have to wonder if at least part of the reason why hydroxyurea benefits so many of the “sicker” sickle cell anemia patients is because it’s helping to control an unrecognized MCAS in these patients. (Interestingly, another researcher at my institution (Dr. Kalpna Gupta) and her team recently discovered that, at least in a mouse model of sickle cell anemia, it’s mast cell activation that causes the lion’s share of the pain from a classic sickle cell vaso-occlusive crisis, and mast cell stabilizers can help decrease this pain. Another noted sickle cell researcher, Dr. Abdullah Kutlar at Georgia Regents University, and his team recently reported that serum tryptase levels are higher in sickle cell patients with chronic pain compared to sickle cell patients without chronic pain.

They were able to alter as many as five different genes at once by delivering five different RNA guides. Jaenisch and his colleagues then implanted these altered eggs in female mice, where they developed into healthy pups. Eighty percent of the time, Jaenisch’s team successfully engineered precisely the changes they desired. A new generation of graduate students silently thanked Jaenisch every day for making their lives easier. Many PhD projects had to start with the creation of a mouse model to study a gene or a disease. It typically took eighteen months to create a line of mice, and often it took more than one try to get the mouse right. Now, with CRISPR, Jaenisch needed only five months to get the job done. * * * — I was working as a reporter during those frenzied years, and I did my best to keep up with CRISPR’s advances. But very soon the parade of CRISPR animals became a stampede.

Mice can learn a specific fear association vicariously by observing another mouse experiencing the fear conditioning. Moreover, this is a social process—learning is enhanced if the mice are related or have mated.4 In another study a mouse would be exposed to an aggressive intruder placed in its cage.5 As shown previously, this produces persistent adverse consequences—a month later, such mice still had elevated glucocorticoid levels and were more anxious and more vulnerable to a mouse model of depression.* Importantly, the same persistent effects would be induced in a mouse merely observing another mouse experiencing that stressful intruder paradigm. An even more striking demonstration of “your pain is my pain” in another species came in a 2006 Science paper from Jeff Mogil of McGill University.6 A mouse would observe another mouse (separated from it by Plexiglas) in pain, and, as a result, its own pain sensitivity increased.* In another part of the study, an irritant would be injected in a mouse’s paw; mice typically lick their paw at that point, with the amount of licking indicating the amount of discomfort.
