Nutrient mixture as a promising adjunct to standard treatment of pancreatic cancer

Summary This study evaluated the effect of a nutrient mixture containing lysine, proline, arginine, ascorbic acid and green tea extract on pancreatic cancer. The experiments, performed with cells, showed that the nutrient mixture inhibited the production of matrix metalloproteinases (MMPs). MMPs are substances produced by cancer cells to digest the surrounding tissues and spread through…

Micronutrients are effective against tumor invasion and metastasis

Summary Metalloproteinases (MMPs) are substances produced by malignant cells to digest the surrounding tissues, induce metastasis and spread through the body. This study examined the effect of various compounds on MMPs. The experiments, executed with human lung cancer cells, indicated that a nutrient mixture (NM) and the green tea-derived compound epigallocatechin gallate (EGCG) inhibited the…

Vitamin C reduces the growth of leukemia cells

Summary This study evaluated the effects of vitamin C (ascorbic acid) against leukemia.
