Scientists identify specific genes associated with post-traumatic stress disorder

A research team has found 18 specific, fixed positions on chromosomes (called loci) that seem to be linked to post-traumatic stress disorder (PTSD).

Scientists discover the origin of rare genetic syndrome

Improvements in DNA sequencing have revealed a rare syndrome triggered by changes in the SATB1gene.

3D genome study reveals molecular regulatory mechanisms of human brain evolution

A team led by Prof. SU Bing from the Kunming Institute of Zoology (KIZ) of the Chinese Academy of Sciences (CAS), Prof. LI Cheng from Peking University, and Prof. ZHANG Shihua from the Academy of Mathematics and Systems Science of CAS has reported the highest resolution by far of the 3D genome of the primate brain, and demonstrated the molecular regulatory mechanisms of human brain evolution through cross-species multi-omics analysis and experimental validation. The study was published in Cell.

Targeting glycoprotein could improve response to immune checkpoint therapy

It was an unexpected discovery that started with an analysis of more than 1,000 genes. The question: why game-changing cancer immunotherapy treatments work for only a fraction of patients.

Study shows TALEN is five times more efficient than CRISPR-Cas9 tool

Using single-molecule imaging, scientists have compared the CRISPR-Cas9 and TALEN genome editing tools.

Study shows how stem cell niche maintain their self-renewal capacity

A typical trait of all stem cells is their potential to renew on their own; however, scientists are unsure about how this ability is sustaining throughout life.

Researchers produce a high-quality reference sequence of the switchgrass genome

Gardeners and farmers around the country recognize that crop varieties grow best in certain regions. Most plant species have adapted to their local environments; for example, crop and ornamental seeds sold for the upper Midwest are often very different than those bred for Texas.

LEAFY protein licenses cell reprogramming to floral fate

Cells don't express all the genes they contain all the time. The portion of our genome that encodes eye color, for example, doesn't need to be turned on in liver cells. In plants, genes encoding the structure of a flower can be turned off in cells that will form a leaf.

New computational method simplifies the analysis of gene-environmental interactions

Scientists from Weill Cornell Medicine and the Ithaca campus at Cornell University have designed a novel computational technique for analyzing environmental and genetic interactions and how they affect disease risk.

Researchers publish a complex genome analysis of switchgrass

Biologists believe they are one step closer to a long-held goal of making a cheap, widely available plant a source for energy and fuel, meaning one of the next big weapons in the battle against climate change may be able to trace its roots to the side of a Texas highway.

Two enzymes drive pre-cancer stem cells into malignancy

Since stem cells can continually self-regenerate, making more stem cells, and differentiate into many different specialized cell types, they play an important role in our development and health.

Study shows why obese mothers tend to have children susceptible to metabolic diseases

A Brazilian study published in the journal Molecular Human Reproduction helps understand why obese mothers tend to have children with a propensity to develop the metabolic disease during their lifetime, as suggested by previous research.

New variant of CRISPR-Cas9 tool expands genomic editing in plants

For the first time, Yiping Qi has represented the College of Agriculture & Natural Resources on the Web of Science 2020 list of Highly Cited Researchers.

Pioneer transcription factors help turn on key genes that give cells unique properties

Biologists have long wondered how complex organisms contain a variety of dramatically different types of cells with specialized functions, even though all of those cells are genetically identical.

Study reveals complete genome of major parasitic flowering plant

On January 22 in Current Biology, a team of Harvard-led researchers presented the most complete genome yet assembled of one of the major Rafflesiaceae lineages, Sapria himalayana.

Researchers identify a new way to stop COVID-19 virus

While the world awaits broad distribution of COVID-19 vaccines, researchers at Ohio University just published highly significant and timely results in the search for another way to stop the virus -- by disrupting its RNA and its ability to reproduce.

Venom of Tiger Rattlesnakes may advance genetic science

Among all rattlesnake species, the Tiger Rattlesnake has the simplest yet most lethal venom. Now, a new study performed by a team of researchers can describe the genetics behind the venomous bite of the Tiger Rattlesnake.

Study reveals genetic variants that increase the risk of nocturnal enuresis

In a large-scale study of Danish children and young people, researchers from Aarhus University have for the first time found genetic variants that increase the risk of nocturnal enuresis - commonly known as bedwetting or nighttime incontinence. The findings provide completely new insights into the processes in the body causing this widespread phenomenon.
