    T-cell receptor clonotypic diversity and specialization in digestive system cancers. (PubMed, NPJ Precis Oncol)
    The most abundant "NYGYTF"-containing clones recognized MLANA, a tumor-associated antigen linked to prognosis and therapeutic responsiveness, underscoring its potential role in CRC progression. Collectively, these findings delineate cancer- and stage-specific TCR repertoire alterations and antigen specificities, highlighting novel biomarkers and therapeutic targets to inform TCR-based diagnostics and personalized immunotherapies in CRC and GC.

    Targeting intratumoral Streptococcus mitis suppresses the progression of esophageal squamous cell carcinoma. (PubMed, Sci China Life Sci)
    When loaded with penicillin, circAAGAB, or both, LTA-MSNs precisely targeted intratumoral S. mitis in ESCC patient-derived xenograft (PDX) models, demonstrating potent tumor-suppressive efficacy. Collectively, our findings reveal that intratumoral S. mitis critically drives ESCC tumorigenesis and represents a promising therapeutic target.

    Integrated Bioinformatics Analysis of Differentially Expressed RNA-Binding Proteins in Human Gliomas. (PubMed, Cell Mol Neurobiol)
    Further, RBPs like RPS8, RPL5, RPS3A, EEF1A1, and EIF4E1B were found to be strongly correlated with patients' overall survival. Taken together, our analyses identified several candidate RBPs which might serve as potential targets for oncological measures against gliomas.

    Young-onset hepatocellular carcinoma following double outlet right ventricle surgery without liver congestion: a case report with genetic analysis. (PubMed, Clin J Gastroenterol)
    This case suggests that non-cirrhotic, early-onset HCC may arise in congenital heart disease patients even without hepatic congestion, implying a different mechanism from post-Fontan hepatocarcinogenesis. Genetic factors may contribute, and screening should be considered in high-risk cases regardless of liver function.

    Targeting PABPC1: A Therapeutic Strategy of Natural Ganoderma Meroterpenoid LZ22 against Triple-Negative Breast Cancer Proliferation. (PubMed, Pharmacol Res)
    Furthermore, through structural optimization of LZ22 guided by molecular docking, we identified a derivative (LZ22-4) with enhanced anti-tumor proliferative activity. These findings not only identify PABPC1 as a valuable therapeutic target for TNBC but also provide new opportunities and novel insights for advancing anti-TNBC drug development with LZ22 as a potential drug leading compound.

    Spatial gene expression profiling identifies prognostic features of residual tumors after neoadjuvant chemotherapy in triple-negative breast cancer. (PubMed, Front Oncol)
    We identified some differentially expressed genes relevant to oncogenic signaling and immunosuppressive tumor-associated macrophages. These findings provide novel insights into factors affecting prognosis in patients with residual disease after NAC for early-stage TNBC.

    Transforming acidic coiled-coil-containing protein 3-mediated lipid metabolism reprogramming impairs CD8+ T-cell cytotoxicity in hepatocellular carcinoma. (PubMed, Signal Transduct Target Ther)
    In summary, tumor-derived TACC3 impairs the tumor-killing activity of CD8+ T lymphocytes through PUFA metabolism-associated crosstalk. Targeting TACC3 represents a novel and practicable strategy to augment ICI efficacy against HCC.

    The Acetyltransferase ARD1 Induces Glutathione Synthesis to Facilitate Ferroptosis Evasion in Hepatocellular Carcinoma. (PubMed, Cancer Res)
    ARD1 suppression promoted sorafenib-mediated ferroptosis in HCC patient-derived xenograft tumors with high ARD1 and GCLC expression. Overall, this research uncovers an oxidative stress-ARD1-PABPC1-GCLC axis with a crucial role in GSH metabolic reprogramming and ferroptosis regulation in HCC and reveals a strategy for ferroptosis-based targeted therapy for HCC.

    A noncanonical cytoplasmic role for BUB1 in restraining DNA damage-induced dsRNA accumulation and sensing within stress granules. (PubMed, Sci Immunol)
    We found increased immune cell infiltration accompanied by elevated type I interferon production from irradiated BUB1-deficient cells caused by enhanced cytoplasmic dsRNA accumulation and activation of the MDA5/MAVS dsRNA-sensing pathway. Mechanistically, we found that after radiation exposure, BUB1 underwent nucleus-to-cytoplasm migration, where it bound and phosphorylated the poly(A)-binding protein PABPC1, which was degraded together with its associated messenger RNAs stored in the stress granules, thereby preventing dsRNA accumulation and activation of the innate immune response.

    PABPC1 SUMOylation enhances cell survival by promoting mitophagy through stabilizing U-rich mRNAs within stress granules. (PubMed, Nat Commun)
    This process facilitates the expression of U-rich genes, such as mitophagy-related genes FUNDC1, BNIP3L, thereby maintaining cellular homeostasis and promoting cell survival under adverse conditions. Our findings reveal that PABPC1 SUMOylation connects stress granule assembly with selective U-rich mRNA stabilization and mitophagy, promoting cancer cell stress adaptation.
