BETHESDA, Md.--(BUSINESS WIRE)--REGENERX BIOPHARMACEUTICALS, INC. (AMEX:RGN) (www.regenerx.com) reported today that researchers at the Institute of Biopharmaceutical Science, National Yang-Ming University, Taipei, Taiwan, found that administering Tß4 up-regulates anti-oxidative enzymes in human corneal epithelial cells supporting its role in corneal protection and resistance to oxidative damage. Oxidants, such as free radicals, are believed to cause tissue damage at the cellular level and harm DNA, mitochondria, and cell membranes, which can lead to pathologies such as skin deterioration, premature aging, and cancer. Anti-oxidants are the subject of a substantial amount of research in the pharmaceutical and cosmetic industries because of their protective effects on tissues.
