... is called anti-angiogenesis. The two-way dialogue begins when cancer cells secrete proteins -- such as vascular endothelial growth factor (VEGF) and angiopoietin 2 -- that alert blood vessels to their presence. These proteins prime the blood vessels to initiate new blood vessel growth. In response, blood v...Midlife brain crisis spawns late-life Alzheimer's
