The ‘death switch’ in sepsis also promotes survival

The adaptor protein thought to be active in killing cells also promotes cellular survival through a dual function Findings indicate that the presence of RIP1 is actually necessary for survival of septic injury Future research will focus on identif...

(Santa Barbara, Calif.) -- -- In nature, it's a dog-eat-dog world, even in the realm of bacteria. Competing bacteria use "toxic darts" to disable each other, according to a new study by UC Santa Barbara biologists. Their research is published i...

Cell suicide gene also plays role in skeletal muscle development

Investigators have discovered that a protein causing mature cells to commit suicide also helps primitive muscle cells called myoblasts fuse together, allowing them to develop into muscles. The finding of this unexpected new role for the protein, called FKHR, suggests that future research might offer clues to how mutated forms of this molecule cause a form of muscle cancer in children called rhabdomyosarcoma.

Research reveals a cellular basis for a male biological clock

Researchers have discovered a cellular basis for what many have long suspected: Men, as well as women, have a reproductive clock that ticks down with age. A recent study revealed that sperm in men older than 35 showed more DNA damage than that of men in the younger age group. In addition, the older men's bodies appeared less efficient at eliminating the damaged cells, which could pass along problems to offspring

Study Identifies Gene That Prevents Nerve Cell Death

Many neurological diseases occur when specific groups of neurons die because of nerve damage, toxins, inflammation, or other factors. A new study suggests that activity of a single gene can stop neurons from dying regardless of what triggers this process. The findings could lead to new ways of treating neurodegenerative diseases.
