Study examines how DNA damage is repaired by antioxidant enzymes

A typical human cell is metabolically active, roaring with chemical reactions that convert nutrients into energy and useful products that sustain life. These reactions also create reactive oxygen species, dangerous by-products ...

Enzyme 'atlas' helps researchers decipher cellular pathways

One of the most important classes of human enzymes are protein kinases—signaling molecules that regulate nearly all cellular activities, including growth, cell division, and metabolism. Dysfunction in these cellular pathways ...

Nanosensors target enzymes to monitor and study cancer

Cancer is characterized by a number of key biological processes known as the "hallmarks of cancer," which remodel cells and their immediate environment so that tumors can form, grow, and thrive. Many of these changes are ...

Team develops a rapid test to measure immunity to SARS-CoV-2

Mount Sinai researchers have developed a rapid blood assay that measures the magnitude and duration of someone's immunity to SARS-CoV-2, the virus that causes COVID-19. This test will allow large-scale monitoring of the population's ...

Integrator: A guardian of the human transcriptome

In a joint collaboration, Danish and German researchers have characterized a cellular activity that protects our cells from potentially toxic by-products of gene expression. This activity is central for the ability of multicellular ...

A novel cellular process to engulf nano-sized materials

Nanometers are one billionth of a meter, a metric typically used to measure molecules and scientific building blocks not visible to the human eye. Materials of tens and/or several hundred nanometers in diameter have unique ...
