Study uncovers genetic similarities between PTSD and other mental health disorders


Study uncovers genetic similarities between PTSD and other mental health disorders
Attempts to identify the genetic causes of neuropsychiatric diseases such as post-traumatic stress disorder (PTSD) through large-scale genome-wide analyses have yielded thousands of potential links. The challenge is further complicated by the wide range of symptoms exhibited by those who have PTSD. For instance, does extreme arousal, anger, or irritation experienced by some have the same genetic basis as the tendency to re-experience traumatic events, another symptom of the disorder?
A new study led by researchers at Yale and the University of California-San Diego (UCSD) provides answers to some of these questions and uncovers intriguing genetic similarities between PTSD and other mental health disorders such as anxiety, bipolar disorder, and schizophrenia. ....

New tool offers data-driven, precision medicine approach to help scientists better understand COVID-19


New tool offers data-driven, precision medicine approach to help scientists better understand COVID-19
It is called PAGER-CoV, and it promises to be an important tool in finding therapies for COVID-19. Simply put, PAGER-CoV is a database packed with nearly 12,000 (so far) pieces of genetic information on the SARS-CoV-2 virus, information that researchers and physicians can use to tailor treatments against the disease.
PAGER-CoV is an extension of PAGER, a database of gene sets created by Jake Chen, Ph.D., professor in the Department of Genetics at the University of Alabama at Birmingham and associate director of the Informatics Institute in the UAB School of Medicine. Chen created PAGER some 10 years ago while he was at Indiana University. As the pandemic spread in early 2020, Chen and his UAB colleagues created a similar system, PAGER-CoV, in response. ....

Plants depend on LEAFY protein that enables cells to change their fate


Plants depend on LEAFY protein that enables cells to change their 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.
These unneeded genes are kept from becoming active by being stowed in dense chromatin, a tightly packed bundle of genetic material laced with proteins.
In a new study in the journal
Nature Communications, biologists from the University of Pennsylvania identified a protein that enables plant cells to reach these otherwise inaccessible genes in order to switch between different identities. ....

Innovative breakthrough promises to diagnose DNA rearrangement mutations


Innovative breakthrough promises to diagnose DNA rearrangement mutations
Doctors are increasingly using genetic signatures to diagnose diseases and determine the best course of care, but using DNA sequencing and other techniques to detect genomic rearrangements remains costly or limited in capabilities.
However, an innovative breakthrough developed by researchers at Virginia Commonwealth University Massey Cancer Center and the VCU Department of Physics promises to diagnose DNA rearrangement mutations at a fraction of the cost with improved accuracy.
Led by VCU physicist Jason Reed, Ph.D., the team developed a technique that combines a process called digital polymerase chain reaction (dPCR) with high-speed atomic force microscopy (HSAFM) to create an image with such nanoscale resolution that users can measure differences in the lengths of genes in a DNA sequence. These variations in gene length, known as polymorphisms, can be key to accurately diagnosing many forms of c ....
