> Researchers at St. Jude Children's Research Hospital in Memphis, TN say that they have found that cell death occurs as a rapid event that occurs with the almost simultaneous release of apoptosis proteins. Researchers had believed that cell death was a sequential event. Apoptosis, they say, swiftly eliminates extraneous, damaged or harmful cells. Article

> A scientific team says that they have identified two genes that trigger cell response to electricity and demonstrated that electrical currents can alter cell movement and speed healing. Article

> Researchers say that different genes may trigger autism in boys and girls, and that different genes may also be responsible for early-onset and late-onset autism. Article

> Researchers at the MassGeneral Institute for Neurodegenerative Disease have identified an enzyme that works to repair damaged cells as a potential target for Huntington's disease. Inhibiting Poly (ADP-ribose) polymerase (PARP1)--which works to repair cells but can in turn kill them when over-activated--may prove a method for treating Huntington's. Article

> CV Therapeutics says that the Journal of Clinical Investigation has published a preclinical study suggesting that CVT-6883 significantly reduced elevated markers of inflammation, fibrosis and pulmonary injury in two separate in vivo models. Release

> Researchers have been struggling to discover why testicular cancer is easier to treat than other metastatic cancers. One working theory by a group of researchers at Johns Hopkins is exploring the "hyperthermic stress response," in which germ cells that make sperm are retained at lower temperatures in the scrotum and die when exposed to normal body temperature. If they're right, they could identify new ways to treat other cancers. Article

> A scientific team at Glasgow's Beatson Institute for Cancer Research has found that mouth cancer develops in two distinct ways. In the most aggressive form of the disease, faults were found in the p53 gene with no expression of the p16 gene that regulates cells. In the first way, cells kept dividing and multiplying, spreading the disease. In the second way, cells were less likely to divide and multiply, making the disease less likely to spread. Article

> A new mouse model has been developed that provides clues why a gene therapy used to treat the rare "Bubble Boy" disease sometimes causes the patient to develop leukemia. Article
