Beyond genes: Lipid helps cell wall protein fold into proper shape

...lso biosynthetic proteins that manufacture complex compounds such as proteins and fats out of simple compounds. "The next goal now that we've defined the phenomenon is to get into the specifics, find the mechanisms by which these proteins fold. What part of the protein interacts with the lipid, and what part ...

U-M researchers identify new blood test for prostate cancer

...his phase, the researcher identified a panel of 22 compounds that best distinguished the prostate cancer blood samples from the controls. Using these 22 markers, only two of 70 controls incorrectly tested positive for prostate cancer, and seven of 59 prostate cancer samples were falsely negative. Next, the r...

Targeting a key enzyme with gene therapy reversed course of Alzheimer's disease in mouse models

...remained elusive. Instead of looking for chemical compounds to inhibit BACE1, Oded Singer, collaborating with the laboratories of Fred H. Gage at the Salk Institute and lead author Eliezer Masliah at UCSD, resorted to small biological molecules, called short interfering RNA, or siRNA, which derail the process...

Suppressing growth hormone in early adulthood may prevent cancer

A modest suppression of growth hormone and related compounds beginning in early adulthood may delay the onset or progression of several types of cancer, researchers from Wake Forest University School of Medicine and other centers reported today at ENDO 2005, the annual meeting of the Endocrine Society, in San ...
