Popis: | Although abnormal expression of eukaryotic initiation factor 6 (eIF6) has been found in several human solid tumors, the functions and underlying mechanisms of eIF6 in the progression of colorectal cancer (CRC) still needs further elucidation. In the present study, large-scale gene analysis based on Oncomine and The Cancer Genome Atlas (TCGA) database revealed significantly higher baseline expression of eIF6 in colorectal cancer than in normal tissues. Furthermore, our Chinese cohort study revealed that high expression of eIF6 was correlated with aggressive characteristics and poor survival in CRC patients. Functional studies using magnetic nanoparticle extraction indicated that eIF6 was an oncogene in CRC cells. Regarding its mechanism, through Gene ontology (GO) and KEGG pathway analysis based on TCGA RNAseq database, we found that eIF6 can activate multiple AKT-related cancer signaling pathways, such as p-AKT\MMP1\cyclinD1\Bcl2-related signaling, to regulate cell proliferation, invasion, cell cycle and apoptosis in CRC. Collectively, these findings suggested that eIF6 can positively regulate AKT-related cancer signaling and enhance tumorigenicity in CRC, and may serve as a potential prognostic indicator and therapeutic target in CRC. |
