Catch and release: Collagen-mediated control of PEDF availability

Cells are like tiny self-contained machines that are constantly fine-tuned in response to both internal and external signals. Some of these signals are induced by extracellular ligands, specialized proteins that bind to specific ...

Lysosome to mitochondria communication regulates longevity

As people get older, they often feel less energetic, mobile or active. This may be due in part to a decline in mitochondria, the tiny powerhouses inside of our cells, which provide energy and regulate metabolism. In fact, ...

Mathematical model reveals behavior of cellular enzymes

Everything a cell does, from dividing in two to migrating to a different part of the body, is controlled by enzymes that chemically modify other proteins in the cell. Researchers at Princeton University have devised a new ...

Methylation and mopping up

LMU researchers have discovered a novel type of chemical modification in bacterial RNAs. The modification is apparently attached to molecules only when cells are under stress, and is rapidly removed during recovery.

Improved pH probes may help toward cancer treatments

Nanopipettes with zwitterionic membranes may offer improved monitoring of changes in pH surrounding living cells, which can indicate traits of invasive cancer cells and their response to treatment, report researchers at Kanazawa ...
