ADAMTS4 and chronic kidney disease: To further elucidate potential correlation of ADAMTS-4 with progression of chronic kidney disease, we correlated ADAMTS-4 IHC staining in interstitial compartment of kidney tissue (PTC and INT) with chronic kidney tissue interstitial fibrosis scores: chronic interstitial score (ci) per Banff classification for TXCI group and IFTA stage for NKB group.
