Analysis of gene expression in lymphoid cells can determine lymphoma cancer
...een discovered, one of the most interesting is the role
of this kinase in cellular differentiation, particularly muscle differentiation."In practical terms, when we overexpress this protein, we are able to promote myogenic differentiation by enhancing the myoD function," says Giordano, who also discovered...
Scientists discover proteins involved in spread of HIV-1 infection
... the newly identified VPS37 proteins play a direct role
in HIV budding. In principle, the VPS37 proteins are therefore potential new drug targets, though of course many significant hurdles remain to be overcome, such as inhibitor screening and potential problems with cellular toxicity."...

of EGCG in normal cells." Some methods of bolstering ROS are inadvertent; for instance, excessive sun exposure can increase ROS to the point of irreversible cell damage. Chronic exposure to carcinogens and certain drugs also can damage salivary gland...
Mouse study shows NPAS3 and NPAS1 genes may be linked to psychosis
...ngst themselves and act as the brain's wiring. The role
of inhibitory interneurons, on the other hand, is to dampen the activity of excitatory neurons. The NPAS1 and NPAS3 proteins are transcription factors that can activate or deactivate other genes. Just which genes they may control is unclear, Dr. ...
