The Language of Genetics In the Interviews of Jane Gitschier
"Tell me, what is it you plan to do with your one wild and precious life?" The question that concludes Mary Oliver's poem, The Summer Day, reminds us not only of a poet inspired by her observations of the natural world but also of Jane Gitschier, a scientist, author, musician, and mother whose relationship with and observations of those around her have contributed so much to our community. This editorial is intended to commemorate and celebrate Jane's series of more than 40 interviews published by PLOS Genetics, spanning ten years of publishing, about a billion years of evolution—from Archea to Brassica, from prions to mammals—and a set of themes and ideas that make the word "eclectic" seem puny by comparison
Scientists←editors←scientists: The past, present, and future of PLoS genetics
PLoS Genetics is different: different not only because of the PLoS-wide vision for open access and new ways of communicating science, but also in terms of administration and leadership. We are, first and foremost, a community journal, where editorial decisions and direction are made by consensus. This model, where responsibility is distributed among a team of more than 80 working scientists in a way that promotes and encourages discussion, has been nourished and developed fully by Wayne Frankel, who has been with the journal since its inception, and first introduced us to PLoS Genetics exactly four years ago. As the founding Editor-in-Chief, Wayne brought us to where we are today—with nearly 150 new submissions per month, a scope that covers the entire tree of life (and occasionally synthetic biology), and a focus on scientific substance together with a goal of serving the interests of both readers and authors. In making the transition from scientist to Editor-in-Chief, and again to scientist earlier this year, Wayne’s contributions have shown how one role can strengthen the other. Happily, he remains an active member of the Editorial Board, shepherding and consulting on manuscripts in the areas of mammalian genetics and neurobiology
A Decad(e) of Reasons to Contribute to a PLOS Community-Run Journal
Whether it's the number of primate digits, the number of Vishnu avatars, or the number of items on David Letterman's lists for the last 30 years, humans have an almost inordinate fascination with the number ten. That fascination has been especially apparent at PLOS these past few months, as we and two of our sister journals celebrate our tenth anniversary in close succession. Recalling the wonderful "Ten Simple Rules" articles published in PLOS Computational Biology, we at PLOS Genetics are publishing a Tenth Anniversary Collection of our Top Ten Research Articles published over the last ten years
Guidelines for genome-wide association studies
Genome-wide association studies (GWAS) have revolutionized human genetics. They have led to the identification of thousands of loci that affect both normal variation and susceptibility to disease, and have clarified our understanding of the genetic architecture of complex traits. In just five years, the methodology has moved from extraordinary to commonplace, and with the advent of affordable genome-scale data collection, GWAS and other genomic technologies are being adopted by model organism researchers. As GWAS applications have evolved so too have the community standards that pertain to them. Here we clarify the editorial policy of PLoS Genetics with regard to these guidelines
Expanding human variation at PLOS Genetics
The “experiments of nature” that underlie genetics engage all organisms equally: from microbes and slime molds to plants and vertebrates, the inextricable connection between genotype and phenotype lies at the core of our community. That community is remarkably diverse, spanning an array of not only organisms but also approaches and questions; indeed, diversity is one of the main reasons we enjoy contributing to the journal
The melanocortin 1 receptor is the principal mediator of the effects of agouti signaling protein on mammalian melanocytes
Kingdom come
The tumultuous events of 2020 have prompted many of us to reflect upon the forces that divide us, like pandemics and politics, as well as the commonalities that unite us, like our shared hope for a better future. Scientists often face a similar problem—when to lump or split the things they study. PLOS Genetics has decided that while plants (Fig 1) obey the same fundamental genetic principles as other organisms, their unique qualities, many of which are critically important to human health and welfare, merit special attention in the same way as our other sections: Cancer Genetics, Epigenetics, Evolution, Methods, Natural Variation, and Prokaryotic Genetics. To support this goal, we are creating a new Plant Genetics section for the journal that will be led by the inaugural Senior Editors Claudia Koehler and Li-Jia Qu
Bringing PLOS Genetics Editors to Preprint Servers
What's the first thing you do after making a cool new discovery? If you're like us, you run up and down the hallway, propelled by excitement, eager to show your latest result to your colleagues. But the hallway is a pretty limited audience, so we soon turn to publishing our work in a peer-reviewed journal to show it to the whole world (assuming it is an open-access journal). That's when the fun of discovery can come to a screeching halt and turn into dreary hours of formatting and online form submission only to wait weeks, if not months, for your manuscript to wend its way through the peer-review system. Preprint servers (PPS) can short-circuit those cheerless steps, at least for a time, and allow the fruits of your labor to be seen immediately by all who are interested. In addition to increasing the visibility of authors' work, PPS provide opportunities for journals to identify manuscripts that are good fit for their audience. In that vein, PLOS Genetics is pleased to announce a new initiative to use PPS for identifying and soliciting manuscripts, as part of PLOS' overall mission to improve the efficiency and accessibility of science communication (and, of course, to make the process less cheerless for authors). As part of that effort, we now have a dedicated team of editors who will focus on identifying manuscripts on PPS that are potentially suitable for publication in PLOS Genetics
Evaluating the strength of genetic results: Risks and responsibilities
In this issue, we are publishing an Editorial Expression of Concern in connection with a recent article on the genetics of multiple sclerosis (MS). In brief, the authors used exome sequencing of families with multiple individuals diagnosed with MS to identify 21 missense or nonsense mutations in 12 genes, and they then suggest that these 12 genes provide a platform for additional research. Following publication, concerns were raised about the validity of some of the statements made in the manuscript, leading us to a series of discussions, both internally and with the authors. The purpose of this editorial is to describe the sequence of events, the rationale for our eventual publication of the Editorial Expression of Concern, and, in doing so, comment and engender discussion more broadly on the role of scientists as editors in what can sometimes be a grey area: the causal relationship between genetic and phenotypic variation
The role of insulin receptor substrate 2 in hypothalamic and β cell function
Insulin receptor substrate 2 (Irs2) plays complex roles in energy homeostasis. We generated mice lacking Irs2 in β cells and a population of hypothalamic neurons (RIPCreIrs2KO), in all neurons (NesCreIrs2KO), and in proopiomelanocortin neurons (POMCCreIrs2KO) to determine the role of Irs2 in the CNS and β cell. RIPCreIrs2KO mice displayed impaired glucose tolerance and reduced β cell mass. Overt diabetes did not ensue, because β cells escaping Cre-mediated recombination progressively populated islets. RIPCreIrs2KO and NesCreIrs2KO mice displayed hyperphagia, obesity, and increased body length, which suggests altered melanocortin action. POMCCreIrs2KO mice did not display this phenotype. RIPCreIrs2KO and NesCreIrs2KO mice retained leptin sensitivity, which suggests that CNS Irs2 pathways are not required for leptin action. NesCreIrs2KO and POMCCreIrs2KO mice did not display reduced β cell mass, but NesCreIrs2KO mice displayed mild abnormalities of glucose homeostasis. RIPCre neurons did not express POMC or neuropeptide Y. Insulin and a melanocortin agonist depolarized RIPCre neurons, whereas leptin was ineffective. Insulin hyperpolarized and leptin depolarized POMC neurons. Our findings demonstrate a critical role for IRS2 in β cell and hypothalamic function and provide insights into the role of RIPCre neurons, a distinct hypothalamic neuronal population, in growth and energy homeostasis
