Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...tion occurs so readily,” said Tristram-Nagle. “Our findings definitely will change how theoreticians think about virus-cell interactions. This same phenomenon could provide a general way that viruses use to infect cells, so it will be exciting to look at other viral systems with our experimental method,” she ...

Cells re-energize to come back from the brink of death

...tain genes that prevent or repair cell damage. The findings also suggest that the increase in GAPDH provides energy to increase autophagy—the process by which a cell “chews up” debris and broken components, such as damaged mitochondria. After disposing of damaged mitochondria the cell can replace these vital ...

Blood test may help signal tumor's remission, return in throat cancer patients

...requently exhibited a return of throat cancer. The findings could help lead to the development of a blood test that enables doctors to detect the recurrence of throat cancer early on, when there is still time to pursue a second line of treatment, such as surgery or drug therapy. “Cancers of the head and neck...

Liver cancer patients with high serum levels of hepatitis B virus face poorer outcomes
