 | December 14, 2010 | Pomegranate may help prevent prostate cancer metastasis | | The American Society for Cell Biology's 50th Annual Meeting held in Philadelphia was the site of a presentation on December 12, 2010 concerning the finding by researchers at the University of California, Riverside of compounds in pomegranate that protect against prostate cancer metastasis. In 2006, University of California, Los Angeles researchers observed a reduction in the increase of prostate specific antigen (PSA) levels in men with prostate cancer who consumed 8 ounces of pomegranate juice per day. (Prostate specific antigen is a serum tumor marker that is measured to evaluate progression of the disease.) Researchers involved in the current study, led by Manuela Martins-Green, PhD of UC Riverside, previously found that specific pomegranate juice concentrations increased cell death in two prostate tumor cell lines that were resistant to testosterone (which is associated with a greater propensity toward metastasis), as well as increased cell adhesion and decreased migration and cells that survived. The team determined that pomegranate juice affects genes involved in adhesion and migration machinery. The current research conducted by Dr Martins-Green's lab identified phenylpropanoids, hydrobenzoic acids, flavones and conjugated fatty acids as compounds responsible for the effects in the cancer cells that were not destroyed. In addition to inhibiting the growth of the tumor cell lines, the compounds inhibited their migration and attraction to a signal that promotes metastasis to the bone. "This is particularly exciting because we can now modify these naturally occurring components of the juice to improve their functions and make them more effective in preventing prostate cancer metastasis," Dr Martins-Green stated. "Because the genes and proteins involved in movement of prostate cancer cells are essentially the same as those involved in movement of other types of cancer cells, the same modified components of the juice could have a much broader impact in cancer treatment." "We expect that further testing for dose-dependent effects, side-effects, etc. should allow usage of these components as a more effective treatment for metastatic prostate cancer than simply drinking the juice," Dr Martins-Green and her associates conclude. | |  |  | | We know that the main danger in prostate cancer (PC) is its ability to metastasize to the bone. The bone is a favored place when PC cells metastasize. Stephen Paget discussed this in 1889 in his essays on The Seed and the Soil: When a plant goes to seed, its seeds are carried in all directions; but they can grow only if they fall on congenial soil. Paget recognized this inclination for cancer of the breast to spread to the bone. The same proclivity is found in PC. Prostate cancer and breast cancer are brother/sister diseases, strikingly alike in a multitude of ways. Most physicians consider the bone a static tissue, but it is exactly the opposite. The bone is constantly undergoing change in a process called remodeling. Bone tissue is formed and lost in the processes of bone formation and bone resorption. This remodeling of the bone tissue occurs every 100 days. The dynamic nature of the bone tissue has been described in medical literature in thousands of peer-reviewed publications. Many patients and physicians are surprised to learn that the bone is extremely rich in growth factors. These growth factors have been implicated in PC growth and metastasis. Therefore, it should come as no surprise that prostate cancer cells consider the bone a haven or sanctuary--congenial soil, to use the words of Paget. | Please join Life Extension's webinar highlighting our latest discoveries for 2011.

Mitochondria are the energy-producing powerhouses of the cells and are found in highest concentrations in metabolically active organs such as the brain, heart, and skeletal muscles. Currently, the only known strategies to generate new mitochondria are long-term, strenuous aerobic exercise or caloric restriction, which are difficult or impractical for most people to implement. Now, Life Extension members have an alternative to counteract the age-related decline in mitochondria with the new Mitochondrial Energy Optimizer with BioPQQ™. Mitochondrial Energy Optimizer with BioPQQ™ is the most complete mitochondrial support formula on the market. It contains a broad spectrum of ingredients to counteract the primary factors of aging while enhancing the ability of mitochondria to produce energy (ATP). The newest addition, an essential micronutrient known as PQQ has actually been shown to stimulate the production of new mitochondria! This cutting-edge formula provides nutrients to counteract mitochondrial decay (one of the primary factors of aging), nutrients to boost the mitochondrial energy-producing capacity, and now, PQQ. Research has confirmed that PQQ’s cell-signaling effects translate to benefits for the cardiovascular, nervous, reproductive and immune systems. | | | PQQ Caps with BioPQQ™  | The enormous amount of energy generated within the mitochondria exposes them to constant free radical attack. The resulting mitochondrial decay is a hallmark of aging. PQQ protects and augments delicate mitochondrial structures to promote youthful cellular function in three distinct ways: - Antioxidant power. Like CoQ10, PQQ is a highly potent antioxidant. Its extraordinary molecular stability enables it to facilitate thousands of biochemical reactions in the mitochondria without breaking down, for maximum antioxidant and bioenergetic support.
- Favorably modulates gene expression. PQQ activates genes that promote formation of new mitochondria— and beneficially interacts with genes directly involved in mitochondrial health. These same genes also support healthy body weight, normal fat and sugar metabolism, and youthful cellular proliferation.
- Mitochondrial defense. Mitochondria possess their own DNA, distinct from the DNA contained in the nucleus. Unfortunately, compared to nuclear DNA, the DNA housed within each mitochondrion is relatively unprotected. PQQ's antioxidant potency and favorable gene expression profile act to support mitochondrial defense.
