NIH Researchers Find RegeneRx's Drug Candidate Regulates Key Proteins Important in Wound RepairResearch Team Offers New Insights Into TB4's Mechanism of Action
BETHESDA, Md.--(HSMN NewsFeed)--Aug. 1, 2006--ReGenerx Biopharmaceuticals (AMEX:RGN ) reported today that researchers at the National Institutes of Health (NIH) found that TB4, administered to wounds in laboratory animals, significantly increased several important wound healing proteins called matrix metalloproteinases (MMPs), including MMP-2 and MMP-9. The researchers surmised that it is likely that other proteinases may also be regulated (up or down) by TB4. The paper, Thymosin B4 Promotes Matrix Metalloproteinase Expression During Wound Repair, was published in the Journal of Cellular Physiology, (D. Philp, et al., 208:195:200; 2006).
According to Dr. Hynda Kleinman, in whose laboratory the research was performed, "these data demonstrate an additional mechanism by which TB4 may promote wound repair. This protein (TB4) may thus accelerate repair by multiple, related, and in some cases, interdependent mechanisms involving cell migration, angiogenesis, inflammatory response and protease production and activity."
Thymosin Beta 4
TB4 is a synthetic version of a naturally occurring peptide present in virtually all human cells. It is a first-in-class drug candidate that promotes endothelial cell differentiation, angiogenesis in dermal tissues, keratinocyte migration, collagen deposition, and down-regulates inflammation. One of TB4's key mechanisms of action is its ability to regulate the cell-building protein, actin, a vital component of cell structure and movement. Additionally, TB4 directly influences the production of laminin-5, a protein responsible for proper adhesion and migration of certain types of mammalian cells and often deficient in patients with EB. It has also recently been reported that TB4 can inhibit or prevent apoptosis (programmed cell death) in ocular tissue and cardiac tissue. Researchers at the National Institutes of Health, and at other academic institutions throughout the U.S., have published numerous scientific articles indicating that TB4 is effective in accelerating dermal and corneal wound healing in several animal models, under a variety of conditions. An article was published in the scientific journal, Nature, indicating that TB4 protects heart tissue following a myocardial infarction (heart attack) in laboratory animals.
