SEL1L–HRD1 Endoplasmic Reticulum-Associated Degradation Controls STING-Mediated Innate Immunity by Limiting the Size of the Activable STING Pool
[Nature Cell Biology] SEL1L or HRD1 deficiency in macrophages specifically amplified STING signaling and immunity against viral infection and tumor growth.

Targeting PD-L2–RGMb Overcomes Microbiome-Related Immunotherapy Resistance
[Nature] The authors showed that the gut microbiome downregulated PD-L2 expression and its binding partner repulsive guidance molecule b to promote anti-tumor immunity, and identified bacterial species that mediated this effect.

BRCA2 Germline Mutations Identify Gastric Cancers Responsive to PARP Inhibitors
[Cancer Research] To analyze responsiveness of gastric cancer to PARP inhibitor, scientists exploited a gastroesophageal adenocarcinoma platform of patient-derived xenografts (PDX) and PDX-derived primary cells and selected 10 PDXs with loss-of-function mutations in HR pathway genes.

Functional Characterization of Age-Dependent p16 Epimutation Reveals Biological Drivers and Therapeutic Targets for Colorectal Cancer
[Journal of Experimental & Clinical Cancer Research] Investigators established a mouse model that replicated two common genetic and epigenetic events observed in human colorectal cancers: Apc mutation and p16 epimutation.

UTP18-Mediated p21 mRNA Instability Drives Adenoma-Carcinoma Progression in Colorectal Cancer
[Cell Reports] 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
[Oncogene] 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.
