    Berberine and Coptidis rhizoma as novel antineoplastic agents: a review of traditional use and biomedical investigations. Tang J, Feng Y, Tsao S, Wang N, Curtain R, Wang Y. J Ethnopharmacol. 2009 Oct 29;126(1):5-17. Epub 2009 Aug 15. PMID: 19686830 doi:10.1016/j.jep.2009.08.009 Conclusions The modern evidences of treating cancer with Huanglian and berberine have a strong linkage with traditional concept and rules of using Huanglian in CM practice. As anticancer candidates with low toxicity, berberine and its altered structure, as well as Huanglian and its formulae, will attract scientists to pursue the potential anticancer effects and the mechanisms by using technologies of genomics, proteomics and other advanced approaches. On the other hand, relatively few in vivo studies have been conducted on anticancer effects of Huanglian and berberine. The clinical application of berberine or Huanglian as novel cancer therapeutic agents requires in vivo validations and further investigations of their anticancer mechanisms.

Beta-glucan - Wikipedia, the free encyclopedia - 0 views

  •  
    β-Glucans (or beta-glucans) are polysaccharides of D-glucose monomers linked by glycosidic bonds. They occur most commonly as cellulose in plants and trees, the bran of cereal grains, the cell wall of baker's yeast, certain types of fungi, and many kinds of mushrooms and bacteria. Some forms of beta glucans are useful in human nutrition as texturing agents and as soluble fiber supplements, but problematic in brewing as excessive levels make the wort too viscous. Yeast derived beta glucans are notable for their immunomodulatory function

Sloan-Kettering - Coriolus Versicolor - 1 views

  •  
    Coriolus versicolor is a mushroom of the Basidiomycetes class. It was used initially in Traditional Chinese medicine as a tonic, but recent studies suggest that it has immunostimulant and anti-tumor properties. Polysaccharide-K (PSK), a proprietary product derived from Coriolus, was developed for cancer treatment in Japan. When used as an adjuvant, PSK appears to improve survival rates in patients with gastric (1) (2) and colorectal (3) (4) (5) cancers. Other Coriolus extracts, such as polysaccharide-peptide (PSP) and VPS, are available as dietary supplements. When used in conjunction with chemotherapy, PSP may benefit patients with advanced non-small cell lung cancer (7). Other clinical studies using Coriolus extract alone or in combination with other botanicals also suggest positive immunomodulatory effects (8) (9). However, studies on breast cancer (10), hepatocellular carcinoma (11), and leukemia (12) produced mixed results. A hot water extract of Coriolus, VPS, was found to enhance development of large intestinal tumors in mice (21). Coriolus extracts are generally well tolerated but minor adverse effects have been reported. Many over-the-counter Coriolus products are not standardized, making it difficult to compare potency between brands. It is also unclear if PSK, PSP and other Coriolus extracts have comparable effects.

Berberine, dosing and safety - wellness.com - 0 views

  •  
    Side Effects and Warnings Berberine has been reported to cause nausea, vomiting, hypertension (high blood pressure), respiratory failure and paresthesias (abnormal sensations such as numbness or tingling); however, clinical evidence of such adverse effects is not prominent in the literature. Rare adverse effects including headache, skin irritation, facial flushing, headache, bradycardia (slowed heart rate) have also been reported with the use of berberine. Use cautiously when taking berberine for longer than eight weeks due to theoretical changes in bacterial gut flora. Use cautiously in individuals with diabetes, as both human and animal studies indicate that berberine may decrease blood sugar levels. Also use cautiously in individuals with hypotension (low blood pressure), as berberine may have antihypertensive effects. Patients with cardiovascular disease should also use caution as berberine has been associated with the development of ventricular arrhythmias in subjects with congestive heart failure. Although not well studied in humans, berberine may also theoretically cause delays in small intestinal transit time or increase the risk of bleeding. Berberine may cause abortion, eye or kidney irritation, nephritis (inflamed kidneys), dyspnea (difficulty breathing), flu-like symptoms, giddiness, lethargy, or liver toxicity. Patients with leukopenia (abnormally low white blood cell count) should use cautiously due to the potential for development of leukopenia symptoms. When injected under the skin, berberine may cause hyperpigmentation in the arm. Use berberine cautiously in individuals with high exposure to sunlight or artificial light due to potential for adverse phototoxic reactions. Avoid in newborns due to potential for increase in free bilirubin, jaundice, and development of kernicterus (brain damage caused by severe newborn jaundice). Use berberine cautiously in children due to a lack of safety information. Pregnancy and Breastfeeding Berberine is not recomme

    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.

Scripps research team solves structure of 'beneficial' virus | Eureka! Science News - 0 views

  •  
    D structure of the virus, known as Seneca Valley Virus-001, reveals that it is unlike any other known member of the Picornaviridae viral family, and confirms its recent designation as a separate genus "Senecavirus." The new study reveals that the virus's outer protein shell looks like a craggy golf ball¬-one with uneven divets and raised spikes-and the RNA strand beneath it is arranged in a round mesh rather like a whiffleball. "It is not at all like other known picornaviruses that we are familiar with, including poliovirus and rhinoviruses, which cause the common cold," says the study's senior author, Associate Professor Vijay S. Reddy, Ph.D., of The Scripps Research Institute. "This crystal structure will now help us understand how Senecavirus works, and how we can take advantage of it." The Senecavirus is a "new" virus, discovered several years ago by Neotropix Inc., a biotech company in Malvern, Pennsylvania. It was at first thought to be a laboratory contaminant, but researchers found it was a pathogen, now believed to originate from cows or pigs. Further investigation found that the virus was harmless to normal human cells, but could infect certain solid tumors, such as small cell lung cancer, the most common form of lung cancer.

Scientists hail the first effective treatment for skin cancer victims - Hea... - 0 views

  •  
    Scientists have developed the first "personalised" drug shown to be effective against advanced melanoma, the deadliest type of skin cancer which is on the rise in Britain. Warnings about the risks of melanoma were heightened this weekend as the fine weather drew thousands to sunbathe outdoors, putting them at increased risk. "Binge tanning", where sunbathers allow their skin to burn in their eagerness to get a tan, is a key cause of the cancer. Melanoma, which starts as a blemish or change to a mole on the skin, is treatable in its early stages but once it has spread to other organs such as the lungs and liver there are no treatment options. Patients with melanoma that has spread usually die within months

Sloan-Kettering - Astragalus - 0 views

  •  
    Astragalus root is used in traditional medicine for its immunestimulating properties. Chinese studies suggest that astragalus, when used with angelica, has renal protective effects (6). In addition, astragalus decreases the proteinuria associated with idiopathic membranous nephropathy (7) as well as possesses natriuretic action (8). Astragalus may also suppress airway hyperreactivity associated with allergic asthma in vivo (9). An herbal formula using astragalus as a major ingredient has been shown to reduce fatigue in athletes (10). Furthermore, astragalus increases M-cholinergic receptor density in senile rats (11), which suggests that it may have a role in combating senility.

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

Berberine : Information on Uses, Dosage & Side Effects on Healthline.com - 0 views

  •  
    "Berberine is a bitter-tasting, yellow, plant alkaloid with a long history of medicinal use in Chinese and Ayurvedic medicine. Berberine is present in the roots, rhizomes and stem bark of various plants including Hydrastis canadensis (goldenseal), Coptis chinensis (coptis or goldenthread), Berberis aquifolium (Oregon grape), Berberis vulgaris (barberry), and Berberis aristata (tree turmeric). Berberine has also been used historically as a dye, due to its yellow color. Clinical trials have been conducted using berberine. There is some evidence to support its use in the treatment of trachomas (eye infections), bacterial diarrhea, and leishmaniasis (parasitic disease). Berberine has also shown antimicrobial activity against bacteria, viruses, fungi, protozoans, helminths (worms), and chlamydia (STD). Future clinical research is warranted in these areas, as well as cardiovascular disease, skin disorders, and liver disorders.

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

Green tea may negate the effects of a common cancer therapy - 0 views

  •  
    (WASHINGTON, February 3, 2009) - Green tea products have become regarded as a valuable health supplement, as studies have shown evidence of its benefit against a variety of diseases, including cancer. However, a new study suggests that some components of green tea may counteract the anticancer effects of one cancer therapy, bortezomib (Velcade®), and may be contraindicated for patients taking this medicine to ensure its maximum therapeutic benefit. This study is being prepublished online today in Blood, the official journal of the American Society of Hematology.

DCA, Dichloroacetate for Cancer - Dr. Weil - 0 views

  •  
    DCA is an organic compound, and a byproduct of TCE (trichloroethylene), a chemical that has been a concern in the development of cancer. In January 2007, researchers at the University of Alberta published a study in the journal Cancer Cell suggesting that DCA showed promise in shrinking tumors in lab rats as well as inhibiting growth of cultured human cancer cells. They hypothesized that DCA may be able to change cancer cells back to normal ones by switching them from the aberrant energy pathways they rely on to those used by normal cells.
