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

    Dichloroacetate (DCA) as a potential metabolic-targeting therapy for cancer. Michelakis ED, Webster L, Mackey JR. Br J Cancer. 2008 Oct 7;99(7):989-94. Epub 2008 Sep 2. Review. PMID: 18766181 doi:10.1038/sj.bjc.6604554 The unique metabolism of most solid tumours (aerobic glycolysis, i.e., Warburg effect) is not only the basis of diagnosing cancer with metabolic imaging but might also be associated with the resistance to apoptosis that characterises cancer. The glycolytic phenotype in cancer appears to be the common denominator of diverse molecular abnormalities in cancer and may be associated with a (potentially reversible) suppression of mitochondrial function. The generic drug dichloroacetate is an orally available small molecule that, by inhibiting the pyruvate dehydrogenase kinase, increases the flux of pyruvate into the mitochondria, promoting glucose oxidation over glycolysis. This reverses the suppressed mitochondrial apoptosis in cancer and results in suppression of tumour growth in vitro and in vivo. Here, we review the scientific and clinical rationale supporting the rapid translation of this promising metabolic modulator in early-phase cancer clinical trials More than 40 nonrandomised trials of DCA in small cohorts of patients have been reported, but the first two randomised control trials of chronic oral therapy with DCA in congenital mitochondrial diseases were reported in 2006. In the first, a blinded placebo-controlled study was performed with oral DCA administered at 25 mg kg-1 day-1 in 30 patients with MELAS syndrome (mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes) (Kaufmann et al, 2006). Most patients enrolled in the DCA arm developed symptomatic peripheral neuropathy, compared with 4 out of 15 in the placebo arm, leading to the termination of the study. Seventeen out of 19 patients had at least partial resolution of peripheral neurological symptoms by 9 months after discontinuation of DCA. This neurotoxicity res

  •  
    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.

White button mushrooms appear to boost immune function - Tufts Journal: Briefs: Healthy... - 0 views

  •  
    White button mushrooms appear to boost immune function It appears that a little fungus may be good for what ails you. That's the conclusion of a new study that found that eating white button mushrooms may boost the immune system and protect against infection. If the research, done on animals, translates to people, it could raise the health-benefit profile of the fungus, which also contains high concentrations of the super-antioxidant ergothioneine, which protects cells from damaging free radicals. "This is the first published study showing the effect of white button mushrooms on immune function," Dayong Wu, a scientist in the Immunology Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts and lead author of the study, published in the June issue of the Journal of Nutrition, told NutraIngredients.com. The research also suggests that the mushroom may boost both innate and acquired immune system health. The innate immune system, the one you're born with, is the body's first line of defense. The acquired immune system revs up if a pathogen makes its way past the innate system and customizes the immune response to target the invader.

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.

Vitamin D levels associated with survival in lymphoma patients - 0 views

  •  
    ScienceDaily (Dec. 5, 2009) - A new study has found that the amount of vitamin D in patients being treated for diffuse large B-cell lymphoma was strongly associated with cancer progression and overall survival. The results will be presented at the annual meeting of the American Society of Hematology in New Orleans. Also, several recent reports have concluded that vitamin D deficiency is associated with poor outcomes in other cancers, including breast, colon and head and neck cancer. This is the first study to look at lymphoma outcome.

    Anticancer properties of Ganoderma lucidum methanol extracts in vitro and in vivo. Harhaji Trajković LM, Mijatović SA, Maksimović-Ivanić DD, Stojanović ID, Momcilović MB, Tufegdzić SJ, Maksimović VM, Marjanović ZS, Stosić-Grujicić SD. Nutr Cancer. 2009;61(5):696-707. PMID: 19838944 DOI: 10.1080/01635580902898743 Anticancer activities of various extracts of the medicinal mushroom, Ganoderma lucidum, have been widely demonstrated and are mainly associated with the presence of different bioactive polysaccharides and triterpenoids. We have evaluated and compared in vitro and in vivo the antitumor effects of two preparations from Ganoderma lucidum: a methanol extract containing total terpenoids (GLme) and a purified methanol extract containing mainly acidic terpenoids (GLpme). Both extracts inhibited tumor growth of B16 mouse melanoma cells inoculated subcutaneously into syngeneic C57BL/6 mice and reduced viability of B16 cells in vitro, whereby GLme exhibited stronger effect. Furthermore, anticancer activity of GLme was demonstrated for the first time against two other rodent tumor cell lines, L929-mouse fibrosarcoma and C6-rat astrocytoma. The mechanism of antitumor activity of GLme comprised inhibition of cell proliferation and induction of caspase-dependent apoptotic cell death mediated by upregulated p53 and inhibited Bcl-2 expression. Moreover, the antitumor effect of the GLme was associated with intensified production of reactive oxygen species, whereas their neutralization by the antioxidant, N-acetyl cysteine, resulted in partial recovery of cell viability. Thus, our results suggest that GLme might be a good candidate for treatment of diverse forms of cancers.

    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.

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.

Cancer Treatment: The Ciritical Factors - lefeurope.com - 0 views

  •  
    Determining the best way of treating cancer remains highly controversial, even among mainstream oncologists. What may surprise the reader is the large number of documented therapies that have been overlooked by establishment medicine. The fundamental objective of this book is to encourage the expedient transfer of published scientific findings from the research bench to the clinical setting where the patient may benefit. This is the concept of translational medicine, which means translating knowledge from the laboratory side of medicine to the front lines of patient care. Physicians who practice translational medicine react uniquely when informed about a novel therapy. Their curiosity first motivates them to evaluate the new approach in order to reaffirm safety and efficacy in the context of treatment that is appropriate to the patient's condition. The dedicated translational physician uses novel therapeutics based on:

Does vitamin D protect against cancer? « Cancer Research UK - Science Update - 0 views

  •  
    This month, the authoritative International Agency for Research into Cancer (IARC) have weighed in on the issue. By gathering a group of expert scientists, they have looked at all the available evidence and published a detailed report on vitamin D and cancer. The massive tome weighs in at 465 pages, but we'll take a look at the key points in the first of two posts looking at the vitamin D debate. It is impossible for us to get more than about five percent of the vitamin D we need from our diet - unless, like Eskimos, we eat oily fish three times a day.

  •  
    Mice fed fish oil and curcumin showed a significantly reduced tumor volume, 25% (P < 0.04) and 43% (P < 0.005), respectively, and importantly, a combination of curcumin and fish oil diet showed > 72% (P < 0.0001) tumor volume reduction. Expression and activity of iNOS, COX-2, and 5-LOX are downregulated, and p21 is upregulated in tumor xenograft fed curcumin combined with fish oil diet when compared to individual diets. The preceding results evidence for the first time that curcumin combined with omega-3 fatty acids provide synergistic pancreatic tumor inhibitory properties.
