Developmental toxicity evaluation of berberine in rats and mice. Jahnke GD, Price CJ, Marr MC, Myers CB, George JD. Birth Defects Res B Dev Reprod Toxicol. 2006 Jun;77(3):195-206. PMID: 16634078 DOI: 10.1002/bdrb.20075 BACKGROUND: Berberine, a plant alkaloid, is found in some herbal teas and health-related products. It is a component of goldenseal, an herbal supplement. Berberine chloride dihydrate (BCD) was evaluated for developmental toxicity in rats and mice. METHODS: Berberine chloride dihydrate was administered in the feed to timed-mated Sprague-Dawley (CD) rats (0, 3625, 7250, or 14,500 ppm; on gestational days [GD] 6-20), and Swiss Albino (CD-1) mice (0, 3500, 5250, or 7000 ppm; on GD 6-17). Ingested doses were 0, 282, 531, and 1313 mg/kg/day (rats) and 0, 569, 841, and 1155 mg/kg/day (mice). RESULTS:There were no maternal deaths. The rat maternal lowest observed adverse effect level (LOAEL), based on reduced maternal weight gain, was 7250 ppm. The rat developmental toxicity LOAEL, based on reduced fetal body weight per litter, was 14,500 ppm. In the mouse study, equivocal maternal and developmental toxicity LOAELs were 5250 ppm. Due to scattering of feed in the high dose groups, a gavage study at 1000 mg/kg/day was conducted in both species. CONCLUSIONS: In rats, maternal, but not fetal adverse effects were noted. The maternal toxicity LOAEL remained at 7250 ppm (531 mg/kg/day) based on the feed study and the developmental toxicity NOAEL was raised to 1000 mg/kg/day BCD based on the gavage study. In the mouse, 33% of the treated females died. Surviving animals had increased relative water intake, and average fetal body weight per litter decreased 5-6% with no change in live litter size. The maternal toxicity LOAEL remained at 5250 ppm (841 mg/kg/day) BCD, based on increased water consumption. The developmental toxicity LOAEL was raised to 1000 mg/kg/day BCD based on decreased fetal body weight.

A new approach to cancer treatment called immunotherapy could spare patients at least some of the grueling battery of chemotherapy treatments by retraining the body's own defenders--the cells of the immune system--to recognize and destroy tumors. Now researchers at Harvard University have developed a simple way to do this inside the body: a polymer implant attracts and trains immune-system cells to go after cancer. The experimental approach has shown great success in animal studies, increasing the survival rate of mice with a deadly melanoma from 0 to 90 percent. The implant could also be used to treat diseases of the immune system such as arthritis and diabetes, and, potentially, to train other kinds of cells, including stem cells used to repair damage to the body.

Berberine inhibits human tongue squamous carcinoma cancer tumor growth in a murine xenograft model. Ho YT, Yang JS, Lu CC, Chiang JH, Li TC, Lin JJ, Lai KC, Liao CL, Lin JG, Chung JG. Phytomedicine. 2009 Sep;16(9):887-90. Epub 2009 Mar 20. PMID: 19303753 Our primary studies showed that berberine induced apoptosis in human tongue cancer SCC-4 cells in vitro. But there is no report to show berberine inhibited SCC-4 cancer cells in vivo on a murine xenograft animal model. SCC-4 tumor cells were implanted into mice and groups of mice were treated with vehicle, berberine (10mg/kg of body weight) and doxorubicin (4mg/kg of body weight). The tested agents were injected once per four days intraperitoneally (i.p.), with treatment starting 4 weeks prior to cells inoculation. Treatment with 4mg/kg of doxorubicin or with 10mg/kg of berberine resulted in a reduction in tumor incidence. Tumor size in xenograft mice treated with 10mg/kg berberine was significantly smaller than that in the control group. Our findings indicated that berbeirne inhibits tumor growth in a xenograft animal model. Therefore, berberine may represent a tongue cancer preventive agent and can be used in clinic.

Safety Study of Seneca Valley Virus in Patients With Solid Tumors With Neuroendocrine Features This study is currently recruiting participants. Verified by Neotropix, September 2008 This is the first study in man of Seneca Valley Virus, a virus which seeks and kills certain tumors in non-human model systems. Subjects in this trial will be patients with advanced cancer displaying certain specified neuroendocrine features, pathologically; they will have exhausted standard methods of treatment for their tumor. The primary purpose of the trial is to determine if the virus may be administered safely. Additional purposes are to learn about the distribution of the virus in the body, the elimination of the virus from the body, the immune response to the virus and whether the virus might have some beneficial effects upon the tumors which the patients have. The first patients will be treated with low amounts of virus and subsequent patients may receive higher amounts. At the end of the trial, it is intended to select a dose for further study.

Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells. Doctors and scientists are excited about stem cells because they have potential in many different areas of health and medical research. Studying stem cells may help explain how serious conditions such as birth defects and cancer come about. Stem cells may one day be used to make cells and tissues for therapy of many diseases, including Parkinson's disease, Alzheimer's disease, spinal cord injury, heart disease, diabetes and arthritis.

Vitamin D's days of obscurity seem pretty much over. Once just an afterthought to most people-relegated to the sides of milk cartons and the pages of medical texts-it's now on the cusp of becoming a full-fledged disease prevention star. Although vitamin D has long been known as an important factor in bone health, a quickly growing body of evidence now shows that it may also help lower the risk of cancer, heart disease, and even premature death.[1], [2] Not surprisingly, scientists and the public have started to take note, particularly of vitamin D's potential to protect against cancer

"Cancer lies dormant in all of us," he wrote in his new book, "Anticancer: A New Way of Life" (Viking, $25.95). "But our bodies are also equipped with a number of mechanisms that detect and keep such (defective) cells in check." Cancer rears its ugly head when things get out of balance, Servan-Schreiber said in an interview. And that can happen if the bad guys that promote the growth of cancer cells (tobacco, excessive alcohol, excessive sugar, hydrogenated fats, environmental pollutants) outnumber the good guys that support our natural defenses (cancer-fighting phytochemicals found in fruits, vegetables, herbs and teas; physical activity; and stress management techniques). But conventional treatment, while indispensable, focuses on a single target: destroying cancer cells. Doctors rarely address the other side: teaching patients how to fortify themselves using nutrition, exercise and stress-management techniques to create an inhospitable environment for cancer.

Second Expert Report\n\nFood, Nutrition, Physical Activity, and the Prevention of Cancer: a Global Perspective\n\nIt began in 2001 with AICR and its international affiliate, WCRF-UK committing themselves to systematically review and analyze the total body of scientific evidence on the relationship of diet, physical activity and weight management to cancer risk. After a rigorous five-year process, Food, Nutrition, Physical Activity, and the Prevention of Cancer: a Global Perspective does just that.

"December 17, 2009 (San Antonio) - A new targeted cancer drug has been shown to shrink tumors in women with metastatic breast cancer after an average of seven other drugs, including Herceptin, failed. The new drug, called T-DM1, combines Herceptin with a potent chemotherapy drug. It's a Trojan horse approach, where Herceptin homes in on cancer cells and delivers the cancer-killing agent directly to its target. Tumors shrank in one-third of women with metastatic breast cancer given T-DM1, says Ian Krop, MD, of the Dana-Farber Cancer Institute in Boston. In another 12%, tumors stopped growing for at least six months. The women remained cancer-free for an average of seven months -- results unheard of in patients this sick, he says. All the women, who had breast tumors for an average of three years, had cancer that had metastasized, or spread to other parts of the body. They had been treated with an average of seven different therapies, including Herceptin, Tykerb, and Xeloda, and each had failed."

"Língzhī (traditional Chinese: 靈芝; simplified Chinese: 灵芝; Japanese: reishi; Korean: yeongji, hangul: 영지) is the name for one form of the mushroom Ganoderma lucidum, and its close relative Ganoderma tsugae. Ganoderma lucidum enjoys special veneration in Asia, where it has been used as a medicinal mushroom in traditional Chinese medicine for more than 4,000 years, making it one of the oldest mushrooms known to have been used in medicine. Lingzhi may possess anti-tumor, immunomodulatory and immunotherapeutic activities, supported by studies on polysaccharides, terpenes, and other bioactive compounds isolated from fruiting bodies and mycelia of this fungus (reviewed by R. R. Paterson[4] and Lindequist et al.[7]). It has also been found to inhibit platelet aggregation, and to lower blood pressure (via inhibition of angiotensin-converting enzyme[8]), cholesterol and blood sugar.[9] Laboratory studies have shown anti-neoplastic effects of fungal extracts or isolated compounds against some types of cancer. In an animal model, Ganoderma has been reported to prevent cancer metastasis,[10] with potency comparable to Lentinan from Shiitake mushrooms.[11] The mechanisms by which G. lucidum may affect cancer are unknown and they may target different stages of cancer development: inhibition of angiogenesis (formation of new, tumor-induced blood vessels, created to supply nutrients to the tumor) mediated by cytokines, cytoxicity, inhibiting migration of the cancer cells and metastasis, and inducing and enhancing apoptosis of tumor cells

Biological therapy is a type of treatment that works with your immune system. It can help fight cancer or help control side effects (how your body reacts to the drugs you are taking) from other cancer treatments like chemotherapy.

Today studies by researchers in the emerging field of Psycho Neuro Immunology, PNI for short, have hard data explaining the mind/body connection.

Age, stress, and poor nutrition can sap our immune system of its effectiveness. Influenza provides one example. During young adulthood, when the body can mount a robust immune response to this common virus, influenza is rarely fatal. Among the elderly, however, the virus is associated with significant rates of death and hospitalization (Nichol KL 2005). The impact of aging on the immune system is profound. As people age, a number of critical immune system components are reduced or slowed, including cellular response, response to vaccines, and antibody production. At the same time, susceptibilities to infection and cancer are increased. Some of this increased susceptibility to disease is linked to chronic inflammation, which is associated with many disorders of aging (Ershler WB et al 2000; Hamerman D 1999; Taaffe DR et al 2000).

Cancer immunotherapies, including cancer vaccines, are novel investigational cancer therapies. In contrast to chemotherapy and radiotherapy regimens that are often associated with severe side effects, cancer immunotherapy stimulates the body's immune system and natural resistance to cancer, thus offering a gentler means of cancer treatment that is less damaging to the rest of the body. Surgery is generally (but not always) performed, prior to immunotherapy, to remove most of the tumor (Hanna MG, Jr. et al 2001; Jocham D et al 2004). Vaccination or immunotherapy prompts the immune system to kill residual cancer cells that persist after surgery and could result in the cancer recurring.

DURHAM, N.C. -- Restricting carbohydrates, regardless of weight loss, appears to slow the growth of prostate tumors, according to an animal study being published this week by researchers in the Duke Prostate Center. "Previous work here and elsewhere has shown that a diet light in carbohydrates could slow tumor growth, but the animals in those studies also lost weight, and because we know that weight loss can restrict the amount of energy feeding tumors, we weren't able to tell just how big an impact the pure carbohydrate restriction was having, until now," said Stephen Freedland, M.D., a urologist in the Duke Prostate Center and lead investigator on this study. The researchers believe that insulin and insulin-like growth factor contribute to the growth and proliferation of prostate cancer, and that a diet devoid of carbohydrates lowers serum insulin levels in the bodies of the mice, thereby slowing tumor growth, Freedland said.
