The Genotype-Tissue Expression (GTEx) project consortia, which includes scientists from the Centre for Genomic Regulation (CRG) in Barcelona, have now published their results from their first pilot study in three Science papers. These finding will contribute to a better understanding of genomic variation and give us new clues about disease susceptibility. The GTEx resource is being developed in part to…
Researchers at Caltech have discovered how an abundant class of RNA genes, called long non-coding RNAs (lncRNAs, pronounced link RNAs) can regulate key genes. By studying an important lncRNA, called Xist, the scientists identified how this RNA gathers a group of proteins and ultimately prevents women from having an extra functional X-chromosome–a condition in female embryos that leads to death…
Excerpt: “In March, a rumor surfaced in the scientific community that was intriguing, and perhaps a bit chilling: According to those in the know, researchers in China had successfully edited the genomes of human embryos, altering their DNA in a way never accomplished in our own species. MIT Technology Review reported on the murmurings that someone had altered the germ line —…
When scientists first made contact with an isolated village of Yanomami hunter-gatherers in the remote mountains of the Amazon jungle of Venezuela in 2009, they marveled at the chance to study the health of people who had never been exposed to Western medicine or diets. But much to their surprise, these Yanomami’s gut bacteria have already evolved a diverse array…
A special section of commentaries and reflections on epigenetic inheritance has been published in the International Journal of Epidemiology, centered on the reprint of the 1989 article “Inheritance of Acquired Epigenetic Variations” by Eva Jablonka and Marion Lamb. ISG faculty members Aaron Panofsky and Hannah Landecker both contributed invited commentaries to the issue, which is now available in advance online…
Today, the journal Nature Genetics released a set of four papers based entirely on the genetic sequences of Icelanders. Their results, which range from the identification of a new Alzheimer’s-associated gene to the age of the most recent male ancestor shared by all humans, are part of a long history of genetic discoveries from deCODE, a company that has been…
