More clues to causes of breast cancer: Hyperactivation of Akt and overexpression of IKBKE observed in 50 percent of human cancers

ScienceDaily (Oct. 27, 2011) — Publishing in the current issue of The Journal of Biological Chemistry, researchers at Moffitt Cancer Center in Tampa, Fla., have discovered additional mechanisms of "Akt" activation and suggest a component of that activation mechanism -- inhibitor of nuclear factor kappa-B kinase subunit epsilon (IKBKE) -- could be targeted as a therapeutic intervention for treating cancer.Akt, also known as protein kinase B, is one of about 500 protein kinases in the human genome....

Lung stem cells offer therapeutic clues

ScienceDaily (Oct. 27, 2011) — Guided by insights into how mice recover after H1N1 flu, researchers at Harvard Medical School and Brigham and Women's Hospital, together with researchers at A*STAR of Singapore, have cloned three distinct stem cells from the human airways and demonstrated that one of these cells can form into the lung's alveoli air sac tissue. What's more, the researchers showed that these same lung stem cells are rapidly deployed in a dynamic process of lung regeneration to combat...
