Timecourse of gene expression in HeLa cells (parental cells and clonal knockouts of MED12 and MED24) following induction by TNFa or IL-1b

ABSTRACT: Activation of nuclear factor kappa B (NF-kB) by inflammatory signals results in nuclear translocation of the transcription factor p65 and induction of gene expression. We identified MED12 and MED24 in an optical pooled CRISPR knockout screen in HeLa-Cas9 cells for genes affecting the activation and/or relaxation of p65 to the cytoplasm following induction by either TNFa or IL-1b. We generated isogenic clonal knockout HeLa-Cas9 lines using crRNA transfection and confirmed that loss of MED12 or MED24 results in delayed relaxation of p65, assayed by live-cell imaging of a p65-mNeonGreen fluorescent fusion.

Gene expression in HeLa cells expressing GFP-IRF3 (non-targeting control and clonal knockouts of DDX58, MAVS, ATP13A1, CAPN15, TADA2B, MED16, and MED24) following Sendai virus (SeV) infection or hpRNA transfection

Project description:IRF3 translocates from the cytoplasm to the nucleus upon recognition of a cytoplasmic RNA stimulus by RIG-I or MDA5. Using an optical pooled CRISPR knockout screen in HeLa-Cas9 cells, we identified ATP13A1, CAPN15, TADA2B, MED16, and MED24 as novel genes affecting the translocation of IRF3 upon Sendai virus infection. We generated isogenic clonal knockout HeLa-Cas9 lines and confirmed that loss of these five novel genes results in either decreased (ATP13A1 and CAPN15) or increased (TADA2B, MED16, and MED24) translocation of IRF3 upon Sendai virus or synthetic hpRNA stimulation.

Determination of MED12 protein interactome

Project description:Here, the goal of our study was to determine the protein-protein interactome of MED12 in resting and activated human T-cells. We immunoprecipitated endogenous MED12 and evaluated the protein interactome in comparison to an isotype-matched IgG as a control.

Med12 ablation promotes anti-tumor function by enhancing tumor intrinsic immunogenicity in Pancreatic ductal adenocarcinoma [CUT&Tag]

Project description:Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers with limited treatment options, including checkpoint blockade (ICB) immunotherapy. Epigenetic dysregulation is a defining feature of tumorigenesis and contributes to immune escape. However, little is known about whether and how epigenetic regulators evade immune surveillance in PDAC. Here, we identified Med12, a subunit of RNA polymerase II, as a mediator of immune escape in PDAC with in vivo CRISPR-Cas9 Screening. In murine PDAC models, Med12 loss effectively promoted infiltration and cytotoxicity of CD8+ T cells and NK cells，thereby sensitized to ICB and led to a marked extension of survival. Mechanistically, Med12 loss derepressed endogenous retroelements via impairing H3K9me3 and increasing H3K27Ac modification, triggering cytosolic RNA-sensing and DNA-sensing pathways as well as the type I interferon pathways. Moreover, Med12 depletion induced H3K27Ac gain in the Med12-binding domains, further enhanced the interferon-related genes transcription. Our results demonstrated the role of Med12 in suppressing tumor-intrinsic immunogenicity, thus provided a potential target or marker for immunotherapy of PDAC.

Genome-wide characterization of MED12 occupancy in human CD34+ cells

Project description:We report ChIP-Seq data for MED12 in human CD34+ cells. Med12 occupies promoter distal regions that regulate specific transcriptional programs required for the homeostasis of the hematopoietic system. 50 milion cells were used to perform ChIP from CD34+ cells with 10 ug of antibody
