    Codon-Specific KRAS Mutations Predict Survival Benefit of Trifluridine/Tipiracil in Metastatic Colorectal Cancer

    Using whole-genome analysis of 37 patients with metastatic colorectal cancer (mCRC) treated with the chemotherapy trifluridine/tipiracil, researchers identified KRAS codon G12 mutations as a potential biomarker of resistance.

    CEMIP, Acting as a Scaffold Protein for Bridging GRAF1 and MIB1, Promotes Colorectal Cancer Metastasis via Activating CDC42/MAPK Pathway

    Scientists identified cell migration-inducing and hyaluronan-binding protein (CEMIP) interacting with GRAF1, and the combination of high-CEMIP and low-GRAF1 predicted poor survival of patients.

    MicroRNA 483–3p Overexpression Unleashes Invasive Growth of Metastatic Colorectal Cancer via NDRG1 Downregulation and Ensuing Activation of the ERBB3/AKT Axis

    Taking advantage of a large panel of human metastatic colorectal cancer xenografts and matched stem-like cell cultures, researchers showed that overexpression of microRNA 483-3p, encoded by a frequently amplified gene locus, confered an aggressive phenotype.

    MESP2 Binds Competitively to TCF4 to Suppress Gastric Cancer Progression by Regulating the SKP2/p27 Axis

    Scientists presented the first report that mesoderm posterior basic helix-loop-helix transcription factor 2 (MESP2) bound to transcription factor 7-like 2 to inhibit the activation of the TCF4/beta-catenin transcriptional complex.

    RTP4 Silencing Provokes Tumor-Intrinsic Resistance to Immune Checkpoint Blockade in Colorectal Cancer

    Investigators subcutaneously transplanted the MC38 colon cancer cells into C57BL/6 mice, intraperitoneally injected anti-PD-1 antibody, and then isolated immune checkpoint blockade-resistant subclones from the recurrent tumors.
