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...

Critical role in programmed cell death identified

Dartmouth Medical School geneticists have found links in the cell death machinery of worms and mammals, opening new avenues for studying and targeting a process vital to development and implicated in cancer and autoimmune diseases. The work, reported in the February 17 issue of Nature, demonstrates the role of mitochondria, the cellular power plant, in prompting worm cells to self destruc...

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...
