...d experimental model and found it not only stopped programmed cell death, but that the protective effects were present even six hours later. The team decided to explore whether oxidative stress triggered by another experimental condition, called serum starvation/H2O2/TNF,, would be similarly inhibited.

...antibody and there was a 4- to 18-fold increase in programmed cell death, or apoptosis, among the cancer cell lines compared to normal control cells. According to Dr. Monga, these results suggest that PDGFR offers an important new therapeutic target for the treatment of HCC.

The cells invaded by the pathogens are quickly marked by the plant for death so that the microbe cannot use them to replicate and spread to the rest of the plant.

...that are involved in inflammation reactions and in programmed cell death or apoptosis. Apoptosis is important in all stages of life. During embryonal development, for example, apoptosis ensures that undesirable or outmoded tissues disappear.

...pes of learning more about how viruses disrupt the programmed death of cells, or apoptosis. "Millions of cells are dying at any given moment in our body," Clem said. "And that's a good thing." Programmed cell death is tidier than necrosis, in which injury prompts inflammatory cells to rush in and clean up. ...In a first, scientists develop tiny implantable biocomputers
