Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

New Houston Methodist research has revealed that a protein associated with neurodegenerative diseases such as dementia and amyotrophic lateral sclerosis (ALS) also plays a role in regulating DNA ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both sides of the DNA helix are cut at once. Healthy cells can normally fix ...

Medical scientist Eduardo Marbán – then at Johns Hopkins and now Cedars-Sinai – found that heart progenitor cells also have a special mechanism where they send out sacs, known as exosomes, which carry ...

Proteins PIF1 and PCNA gather at sites of DNA damage in SETX-deficient cells, indicating activation of the BIR repair system. LA JOLLA, CA—The DNA inside our cells is constantly being damaged, and one ...

Proteins need to fold into specific shapes to perform their functions in cells, but they occasionally misfold, which can ...
