    Novel Light-sensitive Compounds Show Promise For Cancer Therapy  Jul 5, 2009
    According to Mascharak, one advantage of nitric oxide for cancer treatment is that it induces an orderly type of cell death known as apoptosis. Also known as "programmed cell death," apoptosis does not lead to the inflammation, pain, and swelling normally associated with damage to cells and tissues in the body ... The release of nitric oxide after exposure to light quenched the fluorescence, and the cells showed signs of apoptosis within four to eight hours. (Science Daily)

    Early heart attack therapy with bone marrow extract improves cardiac function  Jun 30, 2009
    Both the cell and cell extract therapies resulted in the presence of more blood vessels and less cardiac cell death, or apoptosis, than no therapy. The study also showed that heart function benefitted despite the finding that few of the injected cells remained in the heart at one month after therapy. (EurekAlert!)

    Researchers pinpoint a new enemy for tumor-suppressor p53  Jun 27, 2009
    Loss of Trim24 expression in a breast cancer cell line caused spontaneous programmed cell death - apoptosis. A similar response was confirmed in human lung, colon and prostate cancer cells. (EurekAlert!)

    Cancer In Humans: Cost Of Being Smarter?  Jun 22, 2009
    They found distinct differences in the way apoptosis or programmed cell death operates, suggesting that humans do not "self-destroy" cells as effectively as chimpanzees do. Apoptosis is one of the primary mechanisms by which our bodies destroy cancer cells. (Science Daily)

    Novel Discovery In Dendritic Cell Signalling Pathways Pave The Way For New Therapeutic Targets  Jun 21, 2009
    ScienceDaily (June 20, 2009) Scientists from A*STAR's Singapore Immunology Network (SIgN) and the University of Milano-Bicocca, Italy, have discovered another signaling pathway for the activation and apoptosis, or programmed cell death, of dendritic cells[1 ... The scientists also discovered that the entire activation by CD14 was necessary to cause apoptosis ... Activated dendritic cells have a short life span, and scientists have observed that they undergo apoptosis in order to protect the body... (Science Daily)

    Gaias Evil Twin: Is life its own worst enemy? by Peter Ward, New Scientist  Jun 19, 2009
    Autonomous apoptosis. It is life evolving with life, not earth evolving in response to life. (Harper's Magazine)

    Protein May Be Strongest Indicator Of Rare Lung Disease, Study Shows  Jun 18, 2009
    ScienceDaily (June 17, 2009) Researchers at the University of Cincinnati (UC) have discovered a protein in the lungs that can help in determining progression of the rare lung disease Idiopathic Pulmonary Fibrosis (IPF). Researchers say the protein Serum surfactant protein A is superior to other IPF predictors and could lead to better decisions about treatment and timing of lung transplantation. (Science Daily)

    Red Wine Compound Resveratrol Demonstrates Significant Health Benefits  Jun 16, 2009
    " Low doses of resveratrol improve cell survival as a mechanism of cardio- and neuro-protection, while high doses increase cell death. "The key difference is probably the result of activation of the sirtuins in the nucleus," said Brown. "Low activation reverses age-associated changes, while high activation increases the process of apoptosis or programmed cell death to remove cellular debris. Similar changes are seen with low-dose versus high-dose resveratrol: low-dose resveratrol produces... (Science Daily)

    Health Secrets of Red Wine Uncovered  Jun 16, 2009
    High doses of the compound may prevent cancer by increasing the process of apoptosis (programmed cell death). Low doses improve cardiac health by increasing cellular protection and reducing damage. (MEDLINEplus)

    How Adrenal Cancer Forms: Dysfunctional Telomeres Can Trigger Cancer Mutations  Jun 6, 2009
    It was previously unknown whether cellular senescence or programmed cell death -- apoptosis -- was. (Oct. (Science Daily)
