Mitochondrial DNA mutations play significant role in prostate cancer

Mutations in mitochondrial DNA (mtDNA) playan important role in the development of prostate cancer, according toresearch by scientists at Emory University School of Medicine and theUniversity of California, Irvine. The findings are published onlinethis week in the Proceedings of the National Academy of Sciences(PNAS). Mitochondrial DNA, which is separate from nuclear DNA, is foundin the hun...

Female sex hormones play a vital role in defense against sexually transmitted diseases

Two McMaster University studies, to be published in the Journal of Virology, show that sex hormones have a profound effect on susceptibility of female mice to the herpes simplex virus, type 2 (HSV-2 ), one of the most common sexually transmitted diseases. Charu Kaushic, assistant professor and supervisor of the studies, says the implication of this work is quite significant. "The research...

An HIV Protein Plays a Surprising Role in Gene Activation

Retroviruses are expert manipulators when it comes to co-opting their host's cellular resources. A great deal of human complexity stems from the vast repertoire of proteins and mechanisms dedicated to the business of regulating gene expression, and retroviruses like HIV have evolved myriad ways of redirecting that machinery to their own benefit. Humans and other eukaryotes have three type...

UCSD researchers maintain stem cells without contaminated animal feeder layers

The growth and maintenance of human embryonic stem cells in the absence of contaminated animal products has been demonstrated by University of California, San Diego (UCSD) School of Medicine researchers in the Whittier Institute, La Jolla, California.

White blood cell waste disposal system plays critical regulatory role

A new research study identifies a critical inhibitory step that is a key component of the feedback circuit regulating the balance between neutrophil production and destruction. The research, published in the March issue of Immunity, suggests that the process for disposal of dying neutrophils is actively linked to neutrophil production. A clear understanding of the processes that control neutrophi...
