Ursolic acid - Wikipedia, the free encyclopedia - 0 views

  •  
    Ursolic acid is a pentacyclic triterpene acid, used in cosmetics,[2] that is also capable of inhibiting various types of cancer cells by inhibiting the STAT3 activation pathway[3][4] and human fibrosarcoma cells by reducing the expression of matrix metalloproteinase-9 by acting through the glucocorticoid receptor. Ursolic acid is present in many plants, including apples, basil, bilberries, cranberries, elder flower, peppermint, rosemary, lavender, oregano, thyme, hawthorn, prunes. Apple peels contain high quantity of ursolic acid and related compounds which are responsible for the anti-cancer activity of apple. Ursolic acid can also serve as a starting material for synthesis of more potent bioactive derivatives, such as anti-tumor agents

    Th1/Th2 balance: the hypothesis, its limitations, and implications for health and disease. Kidd P. Altern Med Rev. 2003 Aug;8(3):223-46. Review. PMID: 12946237 Th1 pathways typically produce activation of cytotoxic T lymphocytes (Tc), NK cells, macrophages, and monocytes, all of which can attack cancer cells and generally defend against tumors. 55 IFN-gamma and other Th1 cytokines are typically lower in advanced cancer patients, while the Th2 marker IL-4 can be higher or unchanged.56 Nodules of non-small cell lung cancer freshly removed from patients expressed a marked imbalance toward Th2, as did biopsy samples from basal cell carcinoma.57 In prostate cancer patients IL-2 was low (Th1) and IL-10 high.58 IL-10 is a confirmed Th1-suppressive cytokine, and heightened IL-10 is a common factor in cancer.55 IL-10 has a variety of suppressive effects that include inhibiting Th1 cytokine production, down-regulating APC and NK cell function, and lowering overall T-cell proliferation.57 Especially under the influence of IL-4 (Th2), tumor cells apparently up-regulate IL-10 that suppresses nearby killer cells. Tumor-derived IL-10 has been documented in lymphoma, ovarian carcinoma, melanoma, neuroblastoma, and renal cell and colon carcinoma.57 IL-12 is another cytokine that can be up-regulated by Th1 activity and inhibited by Th2.59 A low IL-12/IL-10 ratio was found in cervical cancer patients.55 Recent clinical studies suggest elevated IL-10 is predictive of a poor prognosis. 57 With both IL-4 and IL-10 being proven inhibitors of Th1 and promoters of Th2 activity, the recognized capability of cancerous tissue to suppress immunity is readily rationalized.

DHA reduces tumor growth - Life Extension Update - 0 views

  •  
    Mice injected with cancer cells experienced significantly elevated levels of C-reactive protein, white blood cells, and lipid peroxidation compared with control mice. These levels were reduced in animals that received cisplatin and/or DHA. While treatment with 125 mg/kg DHA inhibited tumor growth by 38 percent compared to untreated animals, 250 mg/kg suppressed tumor growth by 79 percent, which was a greater effect than that of cisplatin alone (which was associated with a 55 percent reduction). The combination of DHA and cisplatin resulted in an 81 percent inhibition of growth, while reducing elevated white blood cell levels (leukocytosis) to normal levels. Treatment with the higher dose of DHA alone was associated with a similar reduction in white blood cells, which, when elevated, are associated with tumor growth. A strong relationship was observed between tumor growth and white blood cell levels as well as C-reactive protein levels. In another experiment with rats treated with cisplatin, the addition of 250 mg/kg DHA prevented lethal kidney toxicity in 88 percent of the animals that received it, while none of the rats that received cisplatin alone survived.

Another Blow to Magic Bullet Drugs: Statins Impair Brains - 0 views

  •  
    It turns out that statins inhibit not only the liver from making cholesterol but may also block the brain from making cholesterol. That's a serious consequence, according to Yeon-Kyun Shin, a biophysics professor in the department of biochemistry, biophysics and molecular biology at Iowa State, because cholesterol is vital for healthy and optimum brain function. "If you deprive cholesterol from the brain, then you directly affect the machinery that triggers the release of neurotransmitters. Neurotransmitters affect the data-processing and memory functions. In other words, how smart you are and how well you remember things," said Dr. Shin in a statement to the media.

CoQ10 Improves Endothelial Dysfunction in Statin-Treated Type 2 Diabetics - 0 views

  •  
    NEW YORK (Reuters Health) May 29 - Supplementation with coenzyme Q10 (CoQ10) improves endothelial dysfunction in patients with type 2 diabetes on statin therapy, according to results of a study reported in the May issue of Diabetes Care. The vascular benefits of statins might be attenuated by inhibition of CoQ10 synthesis, Dr. Gerald T. Chew and colleagues from University of Western Australia, Perth, note in their report.

Definition of white button mushroom extract - National Cancer Institute Drug Dictionary - 0 views

  •  
    A heat-stable extract of white button mushrooms (Agaricus bisporus) with potential chemopreventive and immunomodulating activities. Phytochemicals, such as polysaccharides and especially beta-D-glucans found in the white button mushroom extract, bind to and inhibit the activity of aromatase, an enzyme responsible for the conversion of androgens to estrogens and which is often upregulated in breast cancer cells. The consequent decrease in estrogen production may result in the suppression of estrogen-dependent cellular proliferation. In addition, this extract may promote dendritic cell (DC) maturation, increase interferon gamma (IFN-gamma) and tumor necrosis factor alpha (TNF-alpha) production, and may enhance natural killer (NK) cell activity, thus amplifying both innate and T cell-mediated immune responses against cancer cells. Check for active clinical trials or closed clinical trials using this agent.
