mRNA expression of the proximal tubule markers, AT1R and ATRAP, in clonal immortalised cells. (a–d) The relative mRNA levels of SGLT2, DPP4, ATRAP and AT1R in 12 clonal immortalized cell (ciRPTEC) clones were determined by RT-qPCR, normalized to 18S ribosomal RNA. The mRNA levels of the original RPTEC (RPTEC-Ori) were set to 1. Data were obtained with three biologically independent experiments. Values represent the means ± standard error.
