miR-147 is increased in cold storage-associated transplantation kidneys and human DGF samples. (A) In situ hybridization analysis of miR-147 and immunostaining of KIM-1 in serial sections of sham control and cold storage-associated transplantation kidneys. Scale bar=50 μm. (B) Quantification of tubules according to miR-147 and KIM-1 staining. (C) qPCR analysis of miR-147 in Dicer WT and KO kidneys at 1, 7, or 14 days after cold storage-associated transplantation or sham surgery. (D) Cellular morphology and in RPTCs with or without CCCP-R treatment for indicated time. (E) Percentage of cell death assessed morphologically and qPCR analysis of miR-147. (F) In situ hybridization showing miR-147 upregulation in human grafts with DGF in comparison with normal (para-cancer) kidney tissues. Scale bar=50 μm. Quantitative data are expressed as mean±SD (n=3–5). Scale bar=100 μm. *P < 0.05 versus control. #P < 0.05 versus WT graft. Carbonyl Cyanide Chlorophenylhydrazone-Recovery, CCCP-R; DGF, delayed graft function; KO, knockout; miR-147, microRNA-147; RPTC, renal proximal tubular cell; WT, wild-type.
