    BRCA2 Germline Mutations Identify Gastric Cancers Responsive to PARP Inhibitors

    To analyze the responsiveness of gastric cancer to PARP inhibitors, scientists exploited a gastroesophageal adenocarcinoma platform of patient-derived xenografts (PDX) and PDX-derived primary cells.

    UTP18-Mediated p21 mRNA Instability Drives Adenoma-Carcinoma Progression in Colorectal Cancer

    Researchers used in-depth quantitative proteomics combined with survival analysis, revealing that the ribosome protein U3 small nucleolar RNA-associated protein 18 homolog (UTP18) was consistently upregulated in the progression of colorectal adenoma to carcinoma.

    Peritoneal High-Fat Environment Promotes Peritoneal Metastasis of Gastric Cancer Cells through Activation of NSUN2-Mediated ORAI2 m5C Modification

    Transcriptome results suggested that NSUN2 expression was significantly upregulated in peritoneal metastasis (PM) and patients with high NSUN2 expression of PM predicted a worse prognosis.

    Abstract

    Glutathione Peroxidase 2 Knockdown Suppresses Gastric Cancer Progression and Metastasis via Regulation of Kynurenine Metabolism

    The authors found that glutathione peroxidase-2 was overexpressed and negatively correlated with poor prognosis by using clinical gastric cancer samples for validation.

    Dihydroartemisinin Inhibited Stem Cell-Like Properties and Enhanced Oxaliplatin Sensitivity of Colorectal Cancer via AKT/mTOR Signaling

    Researchers found that dihydroartemisinin (DHA) inhibited cell viability in HCT116 and SW620 cells. Moreover, DHA decreased cell clonogenicity, and improved oxaliplatin sensitivity.

    Abstract

    Anti-Proliferative Potential and Oxidative Reactivity of Thermo-Oxidative Degradation Products of Stigmasterol and Stigmasteryl Esters for Human Intestinal Cells

    Scientists analyzed the anti-proliferative potential and genotoxicity of thermo-oxidatively treated stigmasterol, stigmasteryl linoleate, and oleate.

    Abstract

    Natural Oncolysis of Enterovirus 71 in Antitumor Therapy of Colorectal Cancer

    Enterovirus 71 (EV71) was exploited to be a novel oncolytic virus in colorectal cancer. It was revealed that EV71 infection could selectively cause colorectal cancer cells cytotoxicity but not primary intestinal epithelial cells.
