Fig-1. Dicer inactivation in mutant mice.

Fig-1 Panel A shows the genotyping of Dicer, Cre and Pax8 genes in mice either homozygote (cKO) or heterozygote (Het) for Dicer and control mice (Ctr). PCR of renal cortical tissues at P50 shows the Dicer allele floxed, wild type and excised forms. Cre is detected only in homozygous and heterozygous cKO mice as expected, while Pax8 is present constitutively in all the groups. Panel B shows western blot analysis of renal zones Cortex/OSOM, ISOM and IM samples from 50 day old mice. A reduced abundance of Dicer in cKO mice can be observed in all the zones. Normalization was carried out with GAPDH. Panel C shows qPCR analysis of Dicer mRNA. A substantial reduction of Dicer can be seen in cKO mice compared to Ctr. Data are expressed as mean ± sem.
