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.

COVID-19 virus can infect heart cells in a lab dish, study shows

A new study shows that SARS-CoV-2, the virus that causes COVID-19 (coronavirus), can infect heart cells in a lab dish, indicating it may be possible for heart cells in COVID-19 patients to be directly infected by the virus.

Genome sequencing reveals signposts in DNA for cancer, disease risk

By sequencing entire genomes for DNA modifications, and analyzing both cancer tissues and healthy ones, Hackensack Meridian Health researchers and doctors have found what could be a key to risks for cancer and other diseases: specific locations in the DNA where those expression changes (methylation) are imbalanced, according to a new publication.

How upregulation of a single gene by SARs-CoV-2 can trigger cytokine storm

The SARS-CoV-19 virus initially has a limited capability to invade, attacking only one intracellular genetic target, the aryl hydrocarbon receptors (AhRs).

Study shows how a fat cell's immune response exacerbates obesity

When obesity occurs, a person's own fat cells can set off a complex inflammatory chain reaction that can further disrupt metabolism and weaken immune response--potentially placing people at higher risk of poor outcomes from a variety of diseases and infections, including COVID-19.

Single-cell-resolution technologies help map brain regions in humans and primates

Using the single-cell-resolution transcriptomics technologies, researchers have performed a large-scale analysis of gene expression in 33 different brain regions of chimpanzees, bonobos, macaques, and humans, and successfully generated a map of the various brain regions with their particular cell structures.
