Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

Study shows why older individuals are vulnerable to COVID-19

A group of tiny RNA that should attack the virus causing COVID-19 when it tries to infect the body are diminished with age and chronic health problems, a decrease that likely helps explain why older individuals and those with preexisting medical conditions are vulnerable populations, investigators report.

Potential for COVID-19 transmission from human eye

A new study published on the preprint server bioRxiv* in May 2020 reports the presence of ACE2 receptors in the eye at high concentrations. These molecules are the entry points for the SARS-CoV-2 virus that is causing the ongoing COVID-19 pandemic.

Single-cell RNA-seq addresses key question in islet cell biology and diabetes research

The pancreas is an abdominal organ that produces digestive enzymes as well as hormones that regulate blood sugar levels. This hormone-producing function is localized to the islets of Langerhans, which constitute clusters of different endocrine cell types.

Interleukin-12 electroporation led to clinical responses in patients with advanced melanoma

Combining intratumoral electroporation of interleukin-12 (IL-12) DNA (tavokinogene telseplasmid, or TAVO) with the immune checkpoint inhibitor pembrolizumab (Keytruda) led to clinical responses in patients with immunologically quiescent advanced melanoma, according to results from a phase II trial.

AHA awards grants to 12 teams for fast-tracked heart and brain health research related to COVID-19

Less than a month after issuing a rapid response call for scientific research proposals for fast-tracked studies of the effects of COVID-19 on the body's cardiovascular and cerebrovascular systems, the American Heart Association has awarded $1.2 million in grants to teams at 12 institutions across the U.S. to begin this unprecedented work.
