Key protein implicated in negative side effects of senescence

Cellular senescence is a state in which normal healthy cells do not have the ability to divide. Senescence can occur when cancer-causing genes are activated in normal cells or when chemotherapy is used on cancer cells. Thus, ...

Loneliness impacts DNA repair

Scientists at the Vetmeduni Vienna examined the telomere length of captive African grey parrots. They found that the telomere lengths of single parrots were shorter than those housed with a companion parrot, which supports ...

Biologists report on the long-term effects of heat stress on cells

Heat shock (or stress) is a well-known factor of cell stress, though its delayed effects remain largely unknown. According to two articles by Russian scientists —a 2015 article in Nucleic Acids Research and a February article ...

Understanding cellular ageing

Researchers at the BBSRC-supported Babraham Institute have mapped the physical structure of the nuclear landscape in unprecedented detail to understand changes in genomic interactions occurring in cell senescence and ageing. ...
