1. Learn how Buthionine Inhibits Cancer Cells

    L-Buthionine sulfoximine is a specific γ-glutamylcysteine synthetase inhibitor that blocks the rate-limiting step of glutathionine biosynthesis and in doing so depletes the intracellular glutathionine pool in both cultured cells and in whole animals. Glutathionine (GSH) is a water-soluble tripeptide composed of glutamine, cysteine, and glycine. Reduced glutathione is the most abundant intracellular small molecule thiol present in mammalian cells and it serves as a potent intracellular antioxidant protecting cells from toxins such free radicals. Changes in glutathionine homeostasis have been implicated in the etiology and progression of a
  2. Tweaking The Immune System Can Help Fight Cancer & Block Angiogenesis

    Cancers that become resistant to an important class of drugs might be made vulnerable by tweaking the immune system, a team led by UCSD researcher Napolene Ferrara has found.
  3. PI3K/Akt/mTOR Pathway: The Main Cancer Breakthrough

    The PI3K/AKT/mTOR pathway is central to cell growth and survival, cell cycle regulation, and programmed cell death.Aberrant activation of this signaling cascade is linked to several disease states, and thus many components of the pathway are attractive targets for therapeutic intervention.
  4. Cycloheximide's Protection against Cancer

    It has been shown that cycloheximide (CHM), a well-known protein synthesis inhibitor, reduces Cytotoxicity induced by 1-B-D-arabinofuranosylcytosine, nitrogen mustard, or X-irradiation in normal cells, such as small intestine or bone marrow cells.
  5. Fiber Linked To Reduced Risk Of Breast Cancer

    A large new epidemiological study appears to provide further evidence that regular intake of fiber from fruits, vegetables and whole grains is associated with a reduced risk of developing breast cancer in women.
  6. A-83-01 Considered A Fighting Component in Cancer Treatment

    In a study on how the ALK-5 inhibitor A-83-01 inhibits Smad signaling and epithelial-to-mesenchymal transition by transforming growth factor-β, A-83-01 was synthesized and characterized a small molecule inhibitor. It is structurally similar to previously reported ALK-5 inhibitors developed by Sawyer et al. (2003) and blocks signaling of type I serine/threonine kinase receptors for cytokines of the TGF-β superfamily (known as activin receptor-like kinases; ALKs).
  7. Anti-Angiogenic Foods: Fight Cancer with Dietary Changes

    Anti-Angiogenic Foods: Fight Cancer with Dietary Changes
    Eating to defeat cancer can simply be done by adding a few cancer fighting angio foods to your meals each day. Why not choose foods that can help reduce your risk of disease?
  8. Withaferin A (WA) FAQS

    Withaferin A (WA) is derived from the medical plant Withania somnifera (commonly known as ashwagandha or Indian winter cherry), which has been safely used for centuries in Indian Ayurvedic medicine for treatment of different ailments. Suppresion of angiogenisis, alteration of cytoskeletal architecture, and inhibition of proteasomal activity by WA has also been documented.
  9. Chemotin and HIF-1

    Hypoxia-inducible factor-1 (HIF-1) is a transcriptional complex that is activated in response to hypoxia and growth factors. HIF-1 plays a central role in tumor progression, invasion, and metastasis.
  10. Vascular Stem Cells and Tumor Angiogenesis - Pt. 2

    HPCs AND THEIR PROGENY The role of hematopoietic cells in tumor angiogenesis has recently received great attention. HPC from the bone marrow emigrate to the blood and tissues and differentiate to form cells of the innate and adaptive immune system. Tumor-infiltrating leukocytes can either protect against or promote tumor formation. The simplest example of the former is loss of immune...
