The cancer 'TRAP' - 2 views

  •  
    "Worcester, MA - Current research suggests that TNF-receptor associated protein-1 (TRAP-1) may prevent cancer cell death. The related report by Leav et al, "Cytoprotective Mitochondrial Chaperone TRAP-1 as a Novel Molecular Target in Localized and Metastatic Prostate Cancer," appears in the January 2010 issue of the American Journal of Pathology. Prostate cancer cells are often resistant to cell death. Researchers led by Dr. Dario C. Altieri of the University of Massachusetts Medical School, therefore, explored the role of TRAP-1, a protein thought to regulate cell death, in prostate cancer survival. TRAP-1 was highly expressed in both high-grade human prostate cancer lesions and mouse models of prostate cancer, but not in benign or normal prostate tissue. In addition, TRAP-1 overexpression in non-cancer prostate cells inhibited cell death, whereas TRAP-1-deficient prostate cancer cells had enhanced levels of cell death. Moreover, treatment with Gamitrinib, which inhibits TRAP-1, resulted in prostate cancer cell death, but not death of non-cancerous prostate cells. Therefore, targeting TRAP-1 via Gamitrinib treatment may be a viable therapeutic strategy for patients with advanced prostate cancer."

    Berberine, a natural product, induces G1-phase cell cycle arrest and caspase-3-dependent apoptosis in human prostate carcinoma cells. Mantena SK, Sharma SD, Katiyar SK. Mol Cancer Ther. 2006 Feb;5(2):296-308. PMID: 16505103 doi: 10.1158/1535-7163.MCT-05-0448 The effectiveness of berberine in checking the growth of androgen-insensitive, as well as androgen-sensitive, prostate cancer cells without affecting the growth of normal prostate epithelial cells indicates that it may be a promising candidate for prostate cancer therapy. The evaluation of ancient herbal medicines may indicate novel strategies for the treatment of prostate cancer, which remains the leading cause of cancer-related deaths in American men (1). In our present investigation, we show that a naturally occurring isoquinoline alkaloid, berberine, significantly inhibits the proliferation and reduces the viability of DU145 and PC-3 as well as LNCaP cells (Fig. 1), which suggests that berberine may be an effective chemotherapeutic agent against both androgen-sensitive and androgen-insensitive prostate cancer cells. Importantly, we found that berberine did not exhibit toxicity to nonneoplastic human prostate epithelial cells under the conditions used, except for a moderate reduction in cell viability at higher concentrations when cells were treated in vitro for an extended period of time. In conclusion, the results of the present study indicate that berberine inhibits proliferation and induces G1-phase arrest and apoptosis in human prostate cancer cells but not in normal human prostate epithelial cells. In addition, we provide mechanistic evidence that berberine-induced apoptosis in prostate carcinoma cells, particularly hormone-refractory prostate carcinoma cells, is mediated through enhanced expression of Bax, disruption of the mitochondrial membrane potential, and activation of caspase-3.

MedlinePlus: Prostate Cancer - 0 views

  •  
    The prostate is the gland below a man's bladder that produces fluid for semen. Prostate cancer is the third most common cause of death from cancer in men of all ages. It is rare in men younger than 40. Levels of a substance called prostate specific antigen (PSA) is often high in men with prostate cancer. However, PSA can also be high with other prostate conditions. Since the PSA test became common, most prostate cancers are found before they cause symptoms. Symptoms of prostate cancer may include Problems passing urine, such as pain, difficulty starting or stopping the stream, or dribbling Low back pain Pain with ejaculation Prostate cancer treatment often depends on the stage of the cancer. How fast the cancer grows and how different it is from surrounding tissue helps determine the stage. Treatment may include surgery, radiation therapy, chemotherapy or control of hormones that affect the cancer.

Briefing: Cannabis compounds fight prostate cancer - health - 19 August 2009 - New Scie... - 2 views

  •  
    "Compounds similar to those found in cannabis have been shown to stop prostate cancer cells from multiplying. Two cannabinoid compounds, JWH-015 and MET, stopped prostate tumour growth in human prostate cells in Petri dishes and also in mice with the disease. They halted the cell-division cycle and killed the cancer cells, and had the greatest effect on aggressive prostate cancer cell types, which do not respond to hormone treatments. Some 192,000 men in the US alone are diagnosed with prostate cancer each year, and researchers Inés Díaz-Laviada Marturet at the University of Alcalá, Spain, and her colleagues say the results could offer hope to those affected. But before you go looking for a dealer, New Scientist answers a few questions"

Vitamin D and Intervention Trials in Prostate Cancer: From Theory to Therapy - 0 views

  •  
    Vitamin D and intervention trials in prostate cancer: from theory to therapy. Schwartz GG. Ann Epidemiol. 2009 Feb;19(2):96-102. Epub 2008 Jul 10. PMID: 18619854 doi:10.1016/j.annepidem.2008.03.007 This suggests that whereas vitamin D (e.g., cholecalciferol) might prevent prostate cancer, existing prostate tumors likely would require treatment with 1,25(OH)(2)D and/or its analogs. The major obstacle to the use of 1,25(OH)(2)D in patients therapeutically is the risk of hypercalcemia. Several maneuvers to reduce this risk, including pulse dosing and the use of less calcemic 1,25(OH)(2)D analogs, have been explored in Phase I-III clinical trials. Once merely a promise, vitamin D-based therapies for prostate cancer may soon be medical practice.

Older Men Urged to Consider a Drug to Prevent Prostate Cancer - NYTimes.com - 0 views

  •  
    For the first time, medical groups have issued guidelines that say healthy older men should consider taking a drug that may reduce their risk of developing prostate cancer, even if they're just among the worried well who go in for regular screenings.\n\nThe drug, finasteride, is already used to treat male pattern baldness and to shrink enlarged prostates. The new guidelines suggest that patients who are already taking finasteride for those conditions or who go for regular prostate cancer screening tests should discuss long-term treatment with the drug with their doctors.

Mayo researchers: Dramatic outcomes in prostate cancer study - 0 views

  •  
    ROCHESTER, Minn. -- Two Mayo Clinic patients whose prostate cancer had been considered inoperable are now cancer free thanks in part to an experimental drug therapy that was used in combination with standardized hormone treatment and radiation therapy. The men were participating in a clinical trial of an immunotherapeutic agent called MDX-010 or ipilimumab. In these two cases, physicians say the approach initiated the death of a majority of cancer cells and caused the tumors to shrink dramatically, allowing surgery. In both cases, the aggressive tumors had grown well beyond the prostate into the

Novel therapy for cancer? from medicineworld.org - 0 views

  •  
    A ground-breaking Canada-wide clinical trial led by Dr. Katherine Borden, at the Institute for Research in Immunology and Cancer (IRIC) of the Universit de Montral, has shown that a common anti-viral drug, ribavirin, can be beneficial in the treatment of cancer patients. Published in the journal Blood (First Edition), the study demonstrates that ribavirin suppresses the activities of the eIF4E gene in patients. This gene is dysregulated in 30 percent of cancers including breast, prostate, head and neck, colon and stomach cancer.

Berberine - Wikipedia, the free encyclopedia - 0 views

  •  
    "Berberine is a quaternary ammonium salt from the group of isoquinoline alkaloids. It is found in such plants as Berberis, goldenseal (Hydrastis canadensis), and Coptis chinensis, usually in the roots, rhizomes, stems, and bark. Berberine is strongly yellow colored, which is why in earlier times berberis species were used to dye wool, leather and wood. Wool is still today dyed with berberine in Northern India Berberine (BBR) is a natural compound with up-regulating activity on both low-density-lipoprotein receptor (LDLR) and insulin receptor (InsR). This one-drug-multiple-target characteristic might be suitable for the treatment of metabolic syndrome.[12] Berberine has been tested and used successfully in experimental[13] and human diabetes mellitus.[14][15][16] Berberine has been shown to lower elevated blood glucose as effectively as metformin.[17] The mechanisms include inhibition of aldose reductase,[18] inducing glycolysis,[19] preventing insulin resistance[20] through increasing insulin receptor expression[14] and acting like incretins. Berberine has drawn extensive attention towards its antineoplastic effects.[43][44] It seems to suppress the growth of a wide variety of tumor cells including breast cancer,[45] leukemia, melanoma,[46] epidermoid carcinoma, hepatoma, oral carcinoma, tongue carcinoma,[47] glioblastoma, prostate carcinoma, gastric carcinoma.[48][49] Animal studies have shown that berberine can suppress chemical-induced carcinogenesis, tumor promotion, tumor invasion,[50][51][52][53][54] prostate cancer,[55][56][57][58] neuroblastoma,[59][60] and leukemia.[34][61] It is a radiosensitzer of tumor cells but not of normal cells

    This web site is dedicated to vitamin D and cancer. This is because exciting new research indicates that vitamin D-whether produced in the skin as a result of exposure to ultraviolet radiation (from sunlight or sun lamps) or obtained from supplementation with cholecalciferol (vitamin D3)-may help cancer patients. However, the research is far from complete.
