Bacteria cooperate to repair damaged siblings

A University of Wyoming faculty member led a research team that discovered a certain type of soil bacteria can use their social behavior of outer membrane exchange (OME) to repair damaged cells and improve the fitness of ...

Laser pulses reveal DNA repair mechanisms

A new straightforward method enables monitoring the response of nuclear proteins to DNA damage in time and space. The approach is based on nonlinear photoperturbation.

Mayo researchers find off/on switch for DNA repair protein

Damage to DNA is a daily occurrence but one that human cells have evolved to manage. Now, in a new paper published in Nature Structural & Molecular Biology, Mayo researchers have determined how one DNA repair protein gets ...

A chaperone for the 'guardian of the genome'

The protein p53 plays an essential role in the prevention of cancer by initiating the controlled death of a cell with damaged genes which is in danger to transform into a cancerous cell. The heat shock protein Hsp90, in turn, ...

Study reveals how cells keep telomerase in check

The natural ends of chromosomes appear alarmingly like broken DNA, much as a snapped spaghetti strand is difficult to distinguish from its intact counterparts. Yet every cell in our bodies must have a way of differentiating ...
