BRIT1 allows DNA repair teams access to damaged sites

Like a mechanic popping the hood of a car to get at a faulty engine, a tumor-suppressing protein allows cellular repair mechanisms to pounce on damaged DNA by overcoming a barrier to DNA access.

Breakthrough in study of how epithelial cells become cancerous

Epithelial cells, which line the surfaces and organs of the body, can protect themselves against cancer by removing unhealthy or abnormal cells through a mechanism known as "apical extrusion," where the damaged cells are ...

How DNA damage affects Golgiā€”the cell's shipping department

In studying the impact of DNA damage on the Golgi, a research team from the University of California, San Diego School of Medicine and the Ludwig Institute for Cancer Research have discovered a novel pathway activated by ...

Observing how EGFR clusters malfunction in cancer cells

For scientists to improve cancer treatments with targeted therapeutic drugs, they need to be able to see proteins prevalent in the cancer cells. This has been an impossible, until now. Thanks to a new microscopy technique, ...

A novel biosensor to detect DNA damage in real time

Double-strand breaks (DSBs) are a type of DNA damage where both strands of DNA break at the same location. They can adversely affect cell growth and functioning. Currently, DSBs are detected by immunostaining techniques, ...

Stem cells: Tuning the death sentence

In this week's issue of Science Signaling (22 January, 2013), Danen and colleagues of the Division of Toxicology of LACDR report novel insights into the question how stem cells decide to commit suicide when their DNA is damaged.
