If a virus could cure cancer, would you get infected? | MetaFilter - 0 views

  •  
    Targeted cancer therapy and gene therapy have been mentioned in the blue before, but oncolytic viruses are the hot young thing. For consideration in cancer treatment, an virus must replicate in and kill a high number of exclusively cancer cells, while sparing healthy tissue. A Philadelphia-based company called Neotropix has won awards for its research into a prime contender - the Seneca Valley Virus. It has been the subject of Phase I adult clinical trials, with Phase II adult and Phase I pediatric clinical trials to start this year. SVV has advantages over some other contenders in that it is a naturally occurring (lest we create a race of mutant zombies) organism and studies so far suggest it is not harmful to healthy human cells. While a number of other oncolytic viruses are being examined, NTX-010 seems able to treat a very wide range of common and rare forms of cancer, some of which are now considered uniformly fatal. In addition, unlike some other tested viruses, it can travel through the bloodstream to treat metastatic and not just local disease. Compared to the side-effects and late effects of chemotherapy and radiation treatment, and because many of the cancers ideal for treatment with an oncolytic virus have no surgical options, this may be the next big breakthrough.

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.

Sham vs. Wham: The Health Insider: Flax in Diet Found to Prevent or Reduce Tumors - 0 views

  •  
    There is new research out this morning from South Dakota State University which offers evidence that including flax in the diet may help prevent colorectal tumors or keep tumors from growing as quickly when they do form. Professor C. Dwivedi, head of SDSU's Department of Pharmaceutical Sciences, directed the study. The study was conducted in mice that develop spontaneous intestinal tumors. This strain of mouse is often used as a model by cancer researchers due to this mutation.

HowStuffWorks "What are stem cells and what are they used for?" - 0 views

  •  
    Stem cells are unprogrammed cells in the human body that can be described as "shape shifters." These cells have the ability to change into other types of cells. Stem cells are at the center of a new field of science called regenerative medicine. Because stem cells can become bone, muscle, cartilage and other specialized types of cells, they have the potential to treat many diseases, including Parkinson's, Alzheimer's, diabetes and cancer. Eventually, they may also be used to regenerate organs, reducing the need for organ transplants and related surgeries. "Stem cells are like little kids who, when they grow up, can enter a variety of professions," Dr. Marc Hedrick of the UCLA School of Medicine says. "A child might become a fireman, a doctor or a plumber, depending on the influences in their life -- or environment. In the same way, these stem cells can become many tissues by making certain changes in their environment."

    Calcium plus vitamin D supplementation and the risk of colorectal cancer. Wactawski-Wende J, Kotchen JM, Anderson GL, Assaf AR, Brunner RL, O'Sullivan MJ, Margolis KL, Ockene JK, Phillips L, Pottern L, Prentice RL, Robbins J, Rohan TE, Sarto GE, Sharma S, Stefanick ML, Van Horn L, Wallace RB, Whitlock E, Bassford T, Beresford SA, Black HR, Bonds DE, Brzyski RG, Caan B, Chlebowski RT, Cochrane B, Garland C, Gass M, Hays J, Heiss G, Hendrix SL, Howard BV, Hsia J, Hubbell FA, Jackson RD, Johnson KC, Judd H, Kooperberg CL, Kuller LH, LaCroix AZ, Lane DS, Langer RD, Lasser NL, Lewis CE, Limacher MC, Manson JE; Women's Health Initiative Investigators. N Engl J Med. 2006 Feb 16;354(7):684-96. Erratum in: N Engl J Med. 2006 Mar 9;354(10):1102. PMID: 16481636 Conclusions Daily supplementation of calcium with vitamin D for seven years had no effect on the incidence of colorectal cancer among postmenopausal women. The long latency associated with the development of colorectal cancer, along with the seven-year duration of the trial, may have contributed to this null finding. Ongoing follow-up will assess the longer-term effect of this intervention.

    Inverse association between serum 25(OH) vitamin D levels and non-melanoma skin cancer in elderly men. Tang JY, Parimi N, Wu A, John Boscardin W, Shikany JM, Chren MM, Cummings SR, Epstein EH Jr, Bauer DC; for the Osteoporotic Fractures in Men (MrOS) Study Group. Cancer Causes Control. 2009 Nov 18. [Epub ahead of print] PMID: 19921445 Our results suggest that a diagnosis of NMSC is not a surrogate for adequate 25(OH)D levels or increased UV exposure, and high 25(OH)D levels may be associated with a reduced risk of NMSC.

Mechanisms of Berberine (Natural Yellow 18)-Induced Mitochondrial Dysfunction: Interact... - 0 views

    Mechanisms of berberine (natural yellow 18)-induced mitochondrial dysfunction: interaction with the adenine nucleotide translocator. Pereira CV, Machado NG, Oliveira PJ. Toxicol Sci. 2008 Oct;105(2):408-17. Epub 2008 Jul 3. PMID: 18599498 doi: 10.1124/jpet.107.128017 The data from the present work appear to show that berberine also presents some degree of toxicity to "nontumor" systems, which should be carefully understood. ANT inhibition in nontumor cells by berberine would be responsible for a decrease in energy production and could also result in MPT induction. To the best of our knowledge, no full toxicity assessment exists for berberine in humans, although its use in several commercially available supplements suggests that the compound may present a relatively wide safety interval. In fact, a study with patients with congestive heart failure treated with 1.2 g/day of oral berberine revealed low toxicity and resulted into an average plasma concentration of 0.11 mg/l which would translate into 0.3µM (Zeng and Zeng, 1999Go). Repeated cumulative treatments, alternative forms of formulation (e.g., topical application vs. injection) or more importantly, active mitochondrial accumulation due to its positive charge would be expected to increase its concentration in cells into the range of concentrations used in this study. Empirical data from nontraditional medicines plus the use of extensive clinical assays would allow the use of berberine as a promising antimelanoma agent while maintaining its safety for humans. In radial/vertical forms of melanoma, a possible topical application of berberine would also be possible, thus minimizing side effects on other organs. In conclusion, the present work identifies the ANT as an important target for berberine, with clear relevance for its proposed antitumor effects.

How does doctor decide Lung cancer treatment - 0 views

  •  
    In this video, Dr. Ramakant Deshpande explaining How does doctor decide Lung cancer treatment for different stages of Lung cancer. Lung cancer and its adversities can be lethal, if remains undiagnosed or left untreated. A multidisciplinary approach can successfully eliminate the cancer from lungs and patient may resume normal life after recovery, says Dr. Ramakant Dehspande, Chief of Thoracic Surgical Oncology, Asian Institute of Oncology. Lung cancer There are different sizes and stages of lung cancer, which are treated differently. Broadly, specialists categorize various types of lung cancer into two basic forms Non-small cell lung cancer and small cell lung cancer. The staging of lung cancer helps in deciding the severity of the disease, course of treatment, and chances of survival. Detection of cancer at an early stage increases the chances of successful treatment and full recovery of the patient. A small legion located in one area is known as the first stage; a little larger tumor is called stage 2; spread within the lungs is called stage 3, and if it spread to other parts then termed as stage 4.
