    RNF43 G659fs Is an Oncogenic Colorectal Cancer Mutation and Sensitizes Tumor Cells to PI3K/mTOR Inhibition

    Investigators found that RNF43_p.G659fs promoted cell growth independent of Wnt signaling. PI3K/mTOR inhibitors yielded promising antitumor activity in RNF43659mut isogenic cell lines and xenograft models, as well as in patient-derived organoids harboring RNF43_p.G659fs mutations.

    RNA Polymerase I Inhibition Induces Terminal Differentiation, Growth Arrest and Vulnerability to Senolytics in Colorectal Cancer Cells

    Scientists showed that loss of the tumor suppressor adenomatous polyposis coli, which constituted the initiating event in the adenoma carcinoma sequence for colorectal cancer, induced expression of RNA polymerase I transcription machinery and subsequently upregulated ribosomal DNA transcription.

    The Effects of Ovalbumin on Proliferation, Migration, and Stemness Properties of Chemoresistant SW480 Colon Cancer Cells

    Researchers investigated the effect of egg ovalbumin on survival, cell cycle, self-renewal ability, stemness properties, and migration in SW480 colon cancer cells and 5-fluorouracil resistant subgroup.

    Abstract

    Suppression of HCT116 Human Colon Cancer Cell Motility by Polymethoxyflavones is Associated with Inhibition of Wnt/β-Catenin Signaling

    Investigators examined the effect of polymethoxyflavones present in citrus peels on Wnt/β-catenin signaling in the HCT116 colorectal cancer cell line.

    Role of TRIM22 in Ulcerative Colitis and Its Underlying Mechanisms

    Scientists explored the role of tripartite motif‑containing 22 (TRIM22) in ulcerative colitis and its potential mechanism and revealed that dextran sulphate sodium increased the expression levels of TRIM22 in HT‑29 cells and TRIM30 in mice.

    Abstract

    RNF31 Inhibition Sensitizes Tumors to Bystander Killing by Innate and Adaptive Immune Cells

    A small-molecule RNF31 inhibitor sensitized colon carcinoma organoids to tumor necrosis factor and greatly enhanced bystander killing of MHC antigen-deficient tumor cells.

    Emerging Roles for lncRNA-NEAT1 in Colorectal Cancer

    Emerging evidence has supported that long non-coding RNAs (lncRNAs) can regulate cell cycle of colorectal cancer (CRC) cells. LncRNA NEAT1 has been verified to participate in colon cancer development and progression. Investigators summarize the emerging roles of NEAT1 in CRC cells.
