An antioxidant found in green tea may increase levels a natural anti-cancer protein
Jonathan Kantrowitz, Health News Report - 3 days ago
------------------------------ An antioxidant found in green tea may increase levels of p53, a natural anti-cancer protein, known as the "guardian of the genome" for its ability to repair DNA damage or destroy cancerous cells. Published today in *Nature Communications*, a study of the direct interaction between p53 and the green tea compound, epigallocatechin gallate (EGCG), points to a new target for cancer drug discovery. "Both p53 and EGCG molecules are extremely interesting. Mutations in p53 are found in over 50% of human cancer, while EGCG is the major anti-oxidant in gree...
