Combinatorial Gene Essentiality and Pharmacological Profiling uncovers enhancer-mediated synthetic lethal interactions with Mediator Kinase [RNA-Seq]

ABSTRACT: Depletion of CDK8 and its paralogue CDK19, resulted in a global down regulation of mRNA expression, and hence we went to investigate the binding of RNA pol II by ChIP seq at the promoter and at the gene body in the DKO cells. To determine the consequence of loss of CDK8/19 in re-defining enhancers and to underpin the molecular mechanism that providing the preferential BET sensitivity for DKO, we performed ChIP sequencing for MED12, a reminiscent mediator kinase component, BRD4 and H3K27Ac. We identified that MED12 redefines the enhancer landscape in the absence of CDK8/19, recruit BRD4 at the cis regions and can be targeted using BET inhibitors

Requirement for the Mediator kinase module for activation of super-enhancer associated genes in colon cancer cells

Project description:RNA sequencing of HCT116 colon cancer cells following single and combined depletions of Mediator kinase module subunits CDK8, CDK19, MED12, MED13 and MED13L and the BET family protein BRD4. The results provide insight into the shared and specific functions of kinase module subunits and BRD4 in regulation of expression of transcriptional programs including genes associated with cancer acquired super-enhancers.

The Mediator Kinase Complex Cooperates with Swi/Snf to Regulate Lineage-Resolved Enhancers and Differentiation [ChIP-Seq]

Project description:Depletion of CDK8 and its paralogue CDK19 in intestinal organoids resulted in the downregulation of genes associated with intestinal secretory cells. To determine the consequence of loss of CDK8/19 in re-defining enhancers we performed ChIP sequencing for MED1, MED12, H3K27Ac and ARID1A. We identified that loss of MED1 and MED12 at super enhancers regulating key intestinal transcription factors and loss of ARID1A binding across intestinal (super-)enhancers.

Transcriptomic analysis of the effects of expression of CDK8/CDK19 and their kinase-inactive mutants in HEK293 cells (WT) and their CDK8/19 double-knockout (dKO) derivatives

Project description:RNA-Seq analysis was carried out to investigate the effects of expression of wild-type CDK8 (CDK8) or CDK19 (CDK19) or their kinase-inactive D173A mutants (CDK8M and CDK19M) in HEK293 cells (WT) and their CDK8/19 double-knockout (dKO) derivatives

Transcriptomic analysis of the in vivo effects of CDK8/19 inactivation in 22Rv1 xenografts growing in intact and castrated NSG mice

Project description:RNA-Seq analysis was carried out to investigate the effects of CDK8/19 inactivation in the tumors formed in intact and castrated NSG mice by different 22Rv1 derivatives, with or without SNX631 treatment. The 22Rv1 derivatives were generated as following: Parental 22Rv1 (Rv1-WT) were transduced with a lentivirus expressing luciferase, yielding the derivative Rv1-Luc. 22Rv1 cells with a double knockout of CDK8 and CDK19 (Rv1-dKO) were made via CRISPR/Cas9. Rv1-dKO cells were further transduced with lentiviruses to generate Rv1-dKO re-expression derivatives that express wild-type CDK19 (Rv1-dKO-CDK19) and the kinase-inactive D173A mutant (Rv1-dKO-CDK19M). SNX631 is a selective and orally bioavalable CDK8/19 inhibtor.

Effects of CDK8/19 Mediator Kinase inhibition on gene expression in castration-resistant prostate cancer cell line 22Rv1 and its derivatives grown in vitro.

Project description:RNA-Seq analysis was carried out to investigate the effects of selective CDK8/19 inhibitor SNX631 on gene expression in different 22RV1 derivatives grown in cell culture, under androgen-supplemented and androgen-deprived conditions. The 22Rv1 derivatives were generated as following: Parental 22Rv1 (Rv1-WT) were transduced with a lentivirus expressing luciferase, yielding the derivative Rv1-Luc. 22Rv1 cells with a double knockout of CDK8 and CDK19 (Rv1-dKO) were made via CRISPR/Cas9. Rv1-dKO cells were further transduced with lentiviruses to generate Rv1-dKO re-expression derivatives that express wild-type CDK8 or CDK19 (Rv1-dKO-CDK8 or Rv1-dKO-CDK19) and kinase-inactive D173A mutants (Rv1-dKO-CDK8M or Rv1-dKO-CDK19M).

Inhibition of CDK8/CDK19 with the small molecule inhibitor SEL120-34A in prostate cancer cell lines (3’ tag DGE)

Project description:The Mediator complex is a multi-subunit protein that modulates gene expression on a genome-wide scale. MED12 and cyclin-dependent kinase 8 (CDK8) or its paralog CDK19 are components of its kinase module that regulate the proliferation of prostate cancer cells. In this study, we investigated how MED12 and CDK8/19 influence cancer-driven processes in prostate cancer cell lines, focusing on AR activity and enzalutamide resistance.
