(C) Representative images and quantification of immunofluorescence analysis of Ki67 in RTECs following 1‐AP treatment after 72 h. Scale bars, 5 µm. (D) RT‐qPCR analysis of p16, p21, and p53 mRNA expression showing upregulation of senescence‐associated cell cycle regulators in RTECs following exposure to 1‐AP after 48 h. (E) Representative images and quantification of immunofluorescence analysis of p21 in RTECs following 1‐AP treatment after 72 h. Scale bars, 5 µm. (F) Heatmap for RT‐qPCR analysis of senescence‐associated secretory phenotype (SASP) factors (IL‐1β, IL‐6, IL‐8, MCP‐1, TGF‐β1, and CXCL1) in RTECs following 1‐AP treatment after 48 h. (G) Schematic illustration of the experimental design showing 1‐AP induced senescence in RTECs and paracrine activation of renal fibroblasts via conditioned media may leads to TIF or renal fibrosis. (H) Heatmap for RT‐qPCR analysis of fibrotic markers ( α‐SMA, POSTN, Col1a2, TIMP1 , and CTGF ) in NRK52F renal fibroblasts exposed to conditioned media from 1‐AP‐treated TECs for 48 h.
