To boost transcription of a target gene, enhancer sequences must make contact with the gene’s promoter. This crucial meeting is mediated by interacting proteins and the formation of chromatin loops that bring distant enhancers and promoters together. Although it’s clear that enhancers increase transcription this way, the primary mechanisms by which an enhancer’s target genes…

Each year, emergency departments in the US treat almost 700,000 people for traumatic brain injury (TBI). The outcome depends largely on the severity and location of the injury, but these aren’t the only factors. Age also plays a role, with children often recovering more fully than do adults. The patient’s diet following the injury may…

Symptoms of schizophrenia most commonly begin to creep up in young adulthood. Although genetics play a major role in this complex disorder, narrowing down the search for the genes involved has proven frustratingly difficult. Risk loci identified by genome-wide association studies (GWAS) may contain several genes, making it unclear which of these contribute to pathology.…

Recombination within the genome isn’t random. This swapping of DNA segments between one chromosome and its homolog preferentially affects specific genome regions called hotspots. These regions can have recombination rates many times higher than other areas of the genome, and the rapid shuffling of genetic information is thought to be important in evolution. The location…

To the unaided eye, Antarctic soil and alpine glaciers may appear to be barren wastelands devoid of life. But some microbes call hostile habitats like these home. Research on one such organism, published in the latest issue of G3, reveals some of the mechanisms behind cold adaptation—and explains why these otherwise hardy creatures can’t survive…

Given the outcome of the US presidential election, some of our members have asked us if they should fear an erosion of federal support for research funding. Others have asked more pointed questions, such as: What is the GSA doing to defend the interests of geneticists? Young scientists, they’ve told us, are now even more…

Last week at The Allied Genetics Conference (TAGC), National Institutes of Health (NIH) Director Francis Collins provided an overview of model organism support from his agency. Collins used a new analysis performed by NIH staff to address concerns expressed by many of the model organism researchers gathered at TAGC, particularly a 2015 analysis by Michael…

Although some proteins have a single career, many—like Dis3—lead a double life. In the yeast Schizosaccharomyces pombe, loss-of-function mutations in dis3 cause defects in mitosis, implying that Dis3 normally supports cell cycle progression. But perplexingly, results in humans suggest that Dis3 normally slows cell cycle progression: mutations that partially disable dis3 contribute to the development…

Model Organism Databases (MODs) and the Gene Ontology Consortium play a crucial “behind-the-scenes” role in the work of model organism geneticists and many other biomedical researchers. This guest post by the newly-formed Alliance of Genome Resources announces the group’s intention to integrate the efforts of the MODs and other genome resources. You can learn more…

I have always been passionate about science and outreach is something I think I’m good at. So when I received an email from GSA saying I was on the shortlist for a very important advocacy and outreach event, I thought about how I might be the best scientist to represent GSA. I drafted the following…

American titans of industry are approaching the business of medical philanthropy just as they do their day jobs: in a big way. It’s not unusual to hear of gifts in the hundreds of millions of dollars, if not the occasional one with close to yet another digit to the left. The inevitable institutes and research…
