MARK2/MARK3 kinases are catalytic co-dependencies of YAP/TAZ in human cancer

Project description:Human cancer is often caused by dysfunctional developmental pathways, but such mechanisms do not always present clear opportunities for therapeutic intervention. This is exemplified by the Hippo tumor suppressor pathway, which is comprised of a kinase module that restrains the function of YAP/TAZ transcriptional coactivators; a pathway that becomes dysregulated in a wide array of human cancers. Hence, YAP/TAZ hyperactivation is a tumorigenic mechanism and a validated therapeutic target in oncology. In this study, we used a paralog co-targeting genetic screening strategy to identify the kinases MARK2/3 as co-dependencies of YAP/TAZ in diverse cancer contexts. We use biochemical and epistasis experiments to show that MARK2/3 phosphorylate and inhibit the activity of Hippo pathway components NF2, MST1/2, and MAP4Ks, which leads to indirect upstream control of LATS1/2 activity. In addition, MARK2/3 directly phosphorylate YAP/TAZ to shield these coactivators from LATS1/2-mediated inhibition. The net consequence of this multi-level regulation is that YAP/TAZ-dependent human cancers have an absolute requirement for MARK2/3 catalytic activity to sustain tumor cell proliferation and viability. To simulate therapeutic targeting of MARK2/3 in vivo, we adapted the EPIYA-repeat region of the CagA protein from H. pylori as a catalytic inhibitor of MARK2/3, which we show exerts potent anti-tumor activity via on-target mechanisms. Together, these findings reveal MARK2/3 as an obligate catalytic requirement for YAP/TAZ function in human cancer; kinase targets that may allow for novel pharmacology that restores Hippo-mediated tumor suppression.

CUT&RUN analysis for NOP16-mediated H3K27me3 alteration in MDA-MB231 cells [CUT&RUN-seq]

Project description:The goal of CUT&RUN-seq is to identify the global alteration of H3K27me3 levels by NOP16 overexpression or deletion in triple negative breast cancer cell line MDA-MB231 cells. Three (or Two) biological replicates were assigned for each group and in total 6 groups were prepared for these CUT&RUN-seq libraries. We mapped about 20 million reads per sample to hg38 human reference genome, and counted and normalized each reads number and identified H3K27me3 distribution.

Knock-down of Ror1 in MDA-MB-231 cell line decreases cell invasiveness

Project description:RNA-Seq profiling of triple-negative MDA-MB-231 cell line with know-down of non-canonical WNT signaling receptor Ror1. The MDA-MB231 cells were either transfected with a non-sense control shRNA (shCTL) or with a ROR1 shRNA (shROR1) construct. The objective was to find expression-responsive targets of these perturbations as potential drivers of MDA-MB231 cell invasiveness.
