A new signaling pathway for mTor-dependent cell growth

The activation of mTor complex 1 in the cell is central to many vital processes in the body such as cell growth and metabolism. Overactivity of this signaling pathway can result in diseases such as in diabetic insulin resistance ...

A light-activated remote control for cells

What if doctors had a remote control that they could use to steer a patient's own cells to a wound to speed up the healing process? Although such a device is still far from reality, researchers reporting in the ACS journal ...

The arrestin-GPCR connection

G-protein coupled receptors (GPCRs) are the "inbox" of environmental messages in mammalian cells. Because of their central role in signaling pathways, mutations resulting in abnormal GPCR functions cause a wide variety of ...

Using a promiscuous inhibitor to uncover cancer drug targets

Scientists at Harvard Medical School and the Dana-Farber Cancer Institute have developed a method that exploits the multitargeted nature of a chemical inhibitor to pinpoint vulnerabilities within cancer cells.

Exotic signaling mechanism in pathogens

The unicellular parasite that causes sleeping sickness differs from other eukaryotes in the mode of regulation of an essential cellular signaling pathway. This provides a promising point of attack for drug development.

Study identifies a 'sensor' that activates cell migration

The cytoskeleton is a structure that not only helps cells maintain their shape and internal organisation, but also enables them to perform functions like movement and migration to sites far from the place where they originated. ...
