Researchers at Indiana University School of Medicine are exploring avenues to heal wounds by identifying proteins that are active in fetuses, but largely inactive in adults and absent in diabetic adults. They have identified a protein called nonselenocysteine-containing phospholipid hydroperoxide glutathione peroxidase, or NPGPx, that fits the bill and could be the basis for therapies aimed at diabetic wound healing. NPGPx is a direct transcriptional target of miR-29. miR-29 is downregulated in fetal tissue, thus NPGPx is active in fetal tissue but becomes mostly inactive in the skin after birth.
