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. ...

Researchers uncover mechanism behind DNA damage control

DNA damage is occurring in our cells all the time due to external agents, such as exposure to sun, or internal agents, like reactive oxygen species. To detect and repair DNA lesions, cells have evolved DNA damage response. ...

The yin and yang of cell signaling

Lysophospholipids (LysoPLs) are potent cellular signaling biomolecules that also maintain the structure, shape and fluidity of cell membranes.
