Benzo(a)pyrene disrupts EP300-mediated epigenetic regulation of HSPA1A to alter membrane tension and promote EMT-associated migration and invasion in lung cancer cells. (PubMed, Ecotoxicol Environ Saf)
These findings uncover a previously unrecognized EP300-H2BK5ac-HSPA1A regulatory pathway that links environmental exposure to biomechanical and epigenetic remodeling in lung cancer. Targeting this axis may offer new strategies to mitigate B(a)P-driven metastasis.

Heat Shock-Induced PI(4)P Increase Drives HSPA1A Translocation to the Plasma Membrane in Cancer and Stressed Cells through PI4KIII Alpha Activation. (PubMed, Cell Stress Chaperones)
Our findings identify PI4KIII alpha activity as a key regulator of PI(4)P accumulation and subsequent HSPA1A recruitment to the PM in stressed and cancer cells. This lipid-mediated response offers new insights into stress adaptation and potentially modifiable pathways for therapeutic interventions to control HSPA1A function in cancer.

Comprehensive single-cell RNA analysis reveals intertumoral microenvironment heterogeneity and hub niche of carcinogenesis in thyroid cancer. (PubMed, NPJ Precis Oncol)
Our study provides a comprehensive single-cell transcriptomic atlas of thyroid cancer, offering profound insights into tumor heterogeneity, the functional roles of key niche cells, and potential biomarkers for anticancer therapy. These findings not only enhance our understanding of thyroid cancer biology but also pave the way for the development of novel therapeutic strategies targeting the TME.

A mitochondrial lipid metabolism-related gene signature predicts prognosis and immune landscape in colorectal cancer. (PubMed, Front Immunol)
Furthermore, in vitro experiments demonstrated that knockdown of two key genes, ABHD4 and YJEFN3, significantly suppressed CRC cell proliferation, migration, and invasion, supporting their potential oncogenic roles. This mitochondrial lipid metabolism-based risk model represents a promising prognostic biomarker, offering potential guidance for personalized therapeutic strategies in CRC management.

Bioinformatics analysis of TCGA data identifies a taurine metabolism-related subtype classification for predicting prognosis in colon adenocarcinoma. (PubMed, J Gastrointest Oncol)
The findings of this study have significant clinical implications, suggesting that our nine-gene prognostic model could be integrated into routine clinical practice to enhance patient stratification and inform treatment decisions for COAD. Future research should focus on prospective validation and exploration of therapeutic targets within the identified genes.

Single-cell hdWGCNA identifies ICI-related-colitis key CD8 + T cells linked to immunotherapy response and prognosis in colon cancer. (PubMed, Discov Oncol)
CIC-key-CD8 T cells are pivotal in modulating the tumour microenvironment and can significantly impact the clinical outcome of colon cancer. Their high infiltration rate correlates with poor outcomes and immunotherapy resistance. Targeting these cells may improve therapeutic strategies for cancer immune checkpoint inhibitor treatments.

Bruceine D inhibits hepatocellular carcinoma by regulating the STAT3 signaling pathway through HSP70. (PubMed, Eur J Med Res)
This study demonstrates that BD exerts potent antitumor effects against HCC by inhibiting proliferation, inducing apoptosis, and suppressing migration, primarily through disruption of the Hsp70/STAT3 signaling axis. With its favorable safety profile, BD represents a promising candidate for further development as a therapeutic agent in HCC.
