Eliminate Data Analysis Bottlenecks in Drug Discovery

...erent proteins, and it's just this one interaction you would want to prevent." But, he says, PGC1 has an unusually close relationship with sirtuin1 that may make for relatively easy picking. PGC1, unlike the vast majority of proteins, only uses sirtuin1 to remove its "decorations," called acetyl groups....

Researchers find gene that may be at root of potato blight

... Research and Development Center in Wooster . "If you take a gun through the metal detector at an airport, the alarms go off," he said. "This gene (Avr3a) sends a signal alerting the plant that it is infected by the pathogen." Phytophthora infestans is the pathogen that causes late blight. For decades,...

Young Blood Revives Aging Muscles, Stanford Researchers Find

...o small task. "It's as big a fishing expedition as you can possibly imagine," he said. With thousands of proteins, lipids, sugars and other small molecules in the blood serum, deciding where to look first would be tantamount to a roll of the dice. What's more, there's no evidence that the same blood comp...

Researchers pioneer new gene therapy technique using natural repair process

.... "SCID is ideal for this sort of therapy because you only need to correct the defect in a small number of immune cells to fix the problem," said Dr. Porteus, assistant professor of pediatrics and biochemistry at UT Southwestern. "This is called selective advantage; the healthy cells grow and divide pre...

Mice brains shrink during winter, impairing some learning and memory

...and learning performance. "We predicted that when you reduce the size of the hippocampus, it would have an impact on learning, and that's what we found," Nelson said. The shrinking of the brain corresponds to a season when the mice may have less need for spatial memory, Nelson said. "They don't mainta...
