Project description:Given that TREX1-deficient tumor cells showed a growth delay in immunocompetent but not immunodeficient hosts, we characterize the consequences of CT26 tumor-intrinsic TREX1 loss on the host immune system by performing single-cell RNA sequencing on intra-tumoral immune cells sorted from control and TREX1 KO CT26 tumors.
Project description:Cdk10 knockout significantly reduced CT26 tumor growth in immunocompetent BALB/c WT mice. To investigate how Cdk10 influences the tumor immune microenvironment in vivo, we performed single-cell RNA sequencing (scRNA-seq) on WT and Cdk10 KO CT26 tumors derived from immunocompetent BALB/c mice.

Project description:Single Cell RNA Sequencing of CT26, CT26-OVA, and CT26-LMP1 mouse tumors
Project description:We performed single-cell RNA-sequencing of tumor immune infiltrates and matched peripheral blood mononuclear cells of checkpoint inhibitor (CPI)-naive stage III-IV metastatic melanoma patients. After sample collection, the same patients received CPI-treatment and their response was assessed.
Project description:Goal: Microsatellite-instable (MSI) tumors are one of the few cancers that respond to immune checkpoint blockade (ICB); however, the mechanism of MSI status development is unclear. Here, we report that protein phosphatase 2A (PP2A) deletion or inactivation converted cold microsatellite-stable (MSS) into MSI tumors. Objectives: Using RNA sequencing data of three CT26-shppp2r1a data and a CT26-scr data, we demonstrate that these intestinal tumors display differential core driver pathways.
Project description:T cell infiltration is essential for immune checkpoint inhibitors to be effective in treating solid cancers. Through a bioinformatic pipeline, we identified a target gene SUN1 that might relate to modulating immune cell infiltration and immune response. Thus, we generated one Sun1_knockout CT26 cell line (Sun1_KO) and two control CT26 cell lines (Sun1_Control) using CRISPR-Cas9. By performing RNA-seq on cultured cells, tumors grown in syngeneic model, and purified tumor cells from tumors grown in syngeneic model, we set out to understand how mouse Sun1 can affect immune-related pathways and immune cell infiltration and anti-PD1 efficacy in BALB/c mice.
Project description:Using single-cell RNA-sequencing (scRNA-seq), we characterize diverse immune cell infiltrates that remodel the tissue microenvironment following senescence activation in female Znrf3 cKO mice.
