    Negative Regulation of TGFβ-Induced Apoptosis by RAC1B Enhances Intestinal Tumorigenesis

    By modeling early stages of adenoma initiation researchers observed a reduced apoptotic rate in RAC1B overexpressing tumors, suggesting protection from apoptosis as a mediator of this phenotype.

    Sanguisorbae Radix Suppresses Colorectal Tumor Growth through PD-1/PD-L1 Blockade and Synergistic Effect With Pembrolizumab in a Humanized PD-L1-Expressing Colorectal Cancer Mouse Model

    Sanguisorbae Radix extract (SRE) effectively inhibited the PD-1/PD-L1 interaction, thereby improving T cell receptor signaling and the NFAT-mediated luciferase activity of T cells. SRE treatment reduced tumor growth in the humanized PD-L1 MC38 cell allograft humanized PD-1 mouse model.

    Low Neoantigen Expression and Poor T Cell Priming Underlie Early Immune Escape in Colorectal Cancer

    Using a versatile platform for modulating neoantigen expression in colorectal cancer organoids and transplantation into the distal colon of mice, researchers showed that low expression precluded productive cross-priming and drove immediate T cell dysfunction.
