Akt Signaling. Akt (v-Akt Murine Thymoma Viral Oncogene)/ PKB (Protein Kinase-B) is a Serine/threonine Kinase that is involved in mediating various biological responses, such as inhibition of Apoptosis and stimulation of cell proliferation. Three mammalian isoforms are currently known: Akt1/PKB- Alpha, Akt2/PKB-Beta and Akt3/PKB-Gamma.
Vascular: Relating to blood vessels. For example, the vascular system in the body includes all of the veins and arteries. And, a vascular surgeon is an expert at evaluating and treating problems of the veins and arteries.
Vascular bypass. (Redirected from Vascular grafting) A vascular bypass (or vascular graft) is a surgical procedure performed to redirect blood flow from one area to another by reconnecting blood vessels. Often, this is done to bypass around a diseased artery, from an area of normal blood flow to another relatively normal area.
