Singapore researchers discover protein that drives cancer progression

Cancers arise when the genetic code of normal cells is altered, causing excessive growth. Researchers from the Cancer Science Institute of Singapore at the National University of Singapore have discovered a protein that drives the growth of cancers of the esophagus or liver by altering the genetic code in a novel way.

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.

Antibiotic resistance genes persist in E. coli through 'genetic capitalism', study shows

We have known for some time that over-use of antibiotics is causing a frightening increase in antibiotic resistance in bacteria, through the rapid spread of antibiotic resistance genes.

Researchers identify osmotic stress as stimulator of cellular waste disposal

Cellular waste disposal, where autophagy and lysosomes interact, performs elementary functions, such as degrading damaged protein molecules, which impair cellular function, and reintroducing the resulting building blocks such as amino acids into the metabolic system.

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).

Research reveals how colored light can help control biological processes in plants

University of East Anglia scientists have helped find a way to control different plant processes - such as when they grow - using nothing but colored light.
