Colorectal cancer (CRC) is a common malignant tumor of the digestive system worldwide. DMC-BH, a curcumin analog, has been reported to possess anticancer properties against human gliomas. However, its effects and mechanism on CRC cells are still unknown. Our present study demonstrated that DMC-BH had stronger cytostatic ability than curcumin against CRC cells and . It effectively inhibited the proliferation and invasion and promoted the apoptosis of HCT116 and HT-29 cells. RNA-Seq and data analysis indicated that its effects might be mediated by regulation of the PI3K/AKT signaling. Western blotting further confirmed that it dose-dependently suppressed the phosphorylation of PI3K, AKT and mTOR. The Akt pathway activator SC79 reversed the proapoptotic effects of DMC-BH on CRC cells, indicating that its effects are mediated by PI3K/AKT/mTOR signaling. Collectively, the results of the present study suggest that DMC-BH exerts more potent effects than curcumin against CRC by inactivating the PI3K/AKT/mTOR signaling pathway.

Numerous diseases have been connected to protein arginine methylations mediated by protein arginine methyltransferase 5 (PRMT5). Clinical investigations of the PRMT5-specific inhibitor GSK3326595 are currently being conducted, and the results are promising for preventing cancers. However, the detailed mechanism of PRMT5 promoting colorectal cancer (CRC) malignant progression remains unclear.

Colorectal cancer (CRC) ranks as the third most prevalent cancer globally and is the second leading cause of cancer mortality. FAM49B, a member of the FAM49 gene family, is a recently identified, evolutionarily conserved gene. Emerging studies indicate that FAM49B plays a role in various cancers, though its specific mechanism in CRC remains largely unexplored.

Background: Gene signatures derived from transcriptomic-causal networks offer potential for tailoring clinical care in cancer treatment by identifying predictive and prognostic biomarkers. This study aimed to uncover such signatures in metastatic colorectal cancer (CRC) patients to aid treatment decisions.
Methods: We constructed transcriptomic-causal networks and integrated gene interconnectivity into overall survival (OS) analysis to control for confounding genes.

Metabolic reprogramming, vital for cancer cells to adapt to the altered microenvironment, remains a topic requiring further investigation for different tumor types. Our study aims to elucidate shared metabolic reprogramming across breast (BRC), colorectal (CRC), and lung (LUC) cancers. Leveraging gene expression data from the Gene Expression Omnibus and various bioinformatics tools like MSigDB, WebGestalt, String, and Cytoscape, we identified key/hub metabolism-related genes (MRGs) and their interactions.
