Team Identifies Switch For Tumor Suppressor Gene

and abrake pedal," says Ludlow. "The RB protein ac...a precise and controlled manner.Disable that brake pedal

Neurosteroids: the missing link?
...e glutamate and GABA. Glutamate is the accelerator pedal
and GABA is the brake pedal. GABA essentially shuts the brainoff." Morrisett explained that neurochemists and electrophysiologists were at odds for almost 20years because one group believed that alcohol strongly activated GABA function while the ot...
UCSF-led study offers insight into cancer development, resistance to therapy: finding focuses on Ras oncogene
...is in a third of cancers, Ras functions like a gas pedal
jammed to the floor, driving a cell into growth and replication overdrive. If coupled with enough other mutations causing destabilization of the cell's growth controls, the Ras oncogene can contribute to the development of cancer. While Ras's direct ...
New metabolic 'switches' discovered
...ole, which means Gpa2 functions as a molecular gas pedal
to turn the pathway on. On the other hand, Gpb1 and Gpb2 subunits play inhibitory signaling roles, which means these proteins function as molecular brakes to constrain signaling between the Gpa2 protein and another unknown target in the metabolic pat...
In some patients with chronic fatigue syndrome, left ventricular function may be involved
...til the subject was no longer able to maintain the pedal
speed due to fatigue, muscle pain, or shortness of breath. Blood pressure, heart rate, and ratings of perceived exertion were obtained at each stage. Failure to increase EF during maximal exercise stage indicates possible abnormalities with left vent...

Lab tests can reveal how patients respond to Gleevec
...ors have a mutant form of KIT that acts like a gas pedal
stuck to the floor, providing a constant stimulus for GIST cells to grow," Heinrich said. A fast-tracked clinical trial proved this hypothesis, and the drug was approved by the FDA in 2002 for patients with advanced GIST. The clinical trial was p...
