Abstract:
Melanoma, an extremely aggressive cancer, causes the most skin cancer-related deaths, due to metastasis to other areas of the body, such as lymph nodes, lungs, liver, brain or bone. It is characterized by high levels of matrix metalloproteinase (MMP)-2 and -9 secretions that degrade the extracellular matrix and basement membrane, allowing cancer cells to spread to distal organs.

Abstract:
Metastasis, commonly to the lung, is the major cause of death from testicular cancer. We studied the effect of a novel nutrient mixture (NM) containing ascorbic acid, amino acids and green tea extract on inhibition of melanoma growth and metastasis using a model of intratesticular inoculation of B16FO cells into nude mice. Male athymic mice (n=12), 10-12 weeks of age, were inoculated with 5X105 B16FO melanoma cells in 100 µL of PBS into the right testis; the left testis was left untreated. After inoculation, the mice were randomly divided into two groups. The Control group (n=6) was fed a regular mouse chow diet and the NM 1% group (n=6) the same diet but supplemented with 1% NM. Four weeks later the mice were sacrificed and the abdominal cavity was opened.

Abstract:
Consumption of a plant-based diet has been associated with prevention of the development and progression of cancer. We have developed strategies to inhibit cancer development and its spread by targeting common mechanisms used by all types of cancer cells that decrease stability and integrity of connective tissue. Our approach to strengthening of collagen and connective tissue compromised in cancer metastasis , tumor growth and angiogenesis has been based on using specific natural components, among them  lysine, proline, ascorbic acid and green tea extract (NM). We have documented synergistic effects of this micronutrient mixture and its effectiveness in controlling key mechanisms of cancer  in vivo and in vitro in a wide variety of cancer cell lines.

Abstract:
Melanoma, an aggressive skin cancer, causes the most skin cancer-related deaths, due to metastasis to other areas of the body, Degradation of the extracellular matrix plays a critical role in the formation of tumors and metastasis and has been found to correlate with the aggressiveness of tumor growth and invasiveness of the cancer. Vitamin C, synthesized by many animals but not by humans, is known to be essential for the structural integrity of the intercellular matrix. Humans must obtain ascorbate by diet and cancer patients have been shown to have very low reserves of vitamin C.

Medical Oncology 2008, 25(3): 333-340

Abstract:
The annual incidence of all forms of skin cancer, the most common of all human cancers, is increasing yearly. A unique nutrient mixture (NM) was shown to exhibit anticancer activity in vivo and in vitro. We examined the effect of NM on the development of skin cancer induced by 7,12-dimethylbezanthracene (DMBA) in female SENCAR mice by a complete carcinogenesis protocol. Mice (n = 55) were divided into four groups and carefully shaved on dorsum.
