We have explored the role of local epithelial GHR signaling in regulating the tissue microenvironment. Despite declining circulating pituitary GH with age, colon epithelial DNA damage and aging trigger local non-pituitary growth hormone (npGH) expression. We showed that accumulated DNA damage, a driving force for age-related pathologies including neoplasia, may result from local npGH- mediated defective DNA damage repair (DDR) and build-up of unrepaired DNA damage resulting in...
