Effect of CDK8/19 inhibitor Senexin A on p21-regulated gene expression in human HT1080 p21-9 cells with IPTG-inducible p21

ABSTRACT: p21 (CDKN1A) expression from an IPTG-inducible promoter in HT1080 p21-9 cells was previously shown to inhibit a set of genes, many of which are involved in cell cycle progression, and to upregulate another set of genes, some of which have been implicated in cancer and age-related diseases. We have now developed Senexin A, a small-molecule inhibitor of p21-induced transcription, which we found to be a selective inhibitor of CDK8 and CDK19. Here we tested the effect of Senexin A on the induction and inhibition of transcription by p21. In this dataset, we include microarray gene expression data from samples of HT1080 p21-9 cells that were either untreated, treated with p21-inducing IPTG alone, with Senexin A alone, or with IPTG and Senexin A. This experiment shows that Senexin A inhibits prim
