Transcriptional and epigenetic analysis of Klotho (KI) gene in AKI and CKD models. RT-qPCR RNA and ChIP-qPCR analysis (see Fig. 4). Klotho transcript levels (mRNA) were normalized to L32 mRNA. Matrix ChIP-qPCR analysis RNA polymerase II (Pol II), and permissive (H3K27Ac, H3K4m3) and repressive (H3K9m2) marks (n = 6 mice from each group). Small solid circle, p < 0.05, large circle, p < 0.01, and no circle, not statistically significant. The downregulated Klotho transcripts were not matched by Pol II levels suggesting that post-transcriptional mechanisms are playing a role (e.g. splicing, message stability). Here, the epigenetic changes that correspond to mRNA levels could be playing a role.
