eIf3a mediates malignant biological behaviors in colorectal cancer through the PI3K/AKT signaling pathway.
Colorectal cancer (CRC) is among the most common gastrointestinal malignancies worldwide. eIF3a is highly expressed in a variety of cancer types, yet its role in CRC remains unclear. We introduced ectopic eIF3a expression in CRC cells to investigate its relevance to various malignant behaviors. Further, we silenced eIF3a to explore its effect on tumor growth in a nude mouse tumor xenograft model. Finally, the molecular mechanisms through which eIF3a regulates malignancy in CRC cells were explored through bioinformatics analysis combined with the use of a specific PI3K inhibitor (LY294002). eIF3a was highly expressed in the peripheral blood and cancer tissue of CRC patients. Malignancy and tumor growth were significantly inhibited by silencing eIF3a, while overexpression promoted malignant behaviors, with a positive correlation between PI3K/AKT activation and eIF3a expression. Taken together, eIF3a plays an oncogenic role in CRC by regulating PI3K/AKT signaling and is a potential biomarker for CRC diagnosis and prognostic monitoring.
期刊介绍：
Cancer, the second leading cause of death, is a heterogenous group of over 100 diseases. Cancer is characterized by disordered and deregulated cellular and stromal proliferation accompanied by reduced cell death with the ability to survive under stresses of nutrient and growth factor deprivation, hypoxia, and loss of cell-to-cell contacts. At the molecular level, cancer is a genetic disease that develops due to the accumulation of mutations over time in somatic cells. The phenotype includes genomic instability and chromosomal aneuploidy that allows for acceleration of genetic change. Malignant transformation and tumor progression of any cell requires immortalization, loss of checkpoint control, deregulation of growth, and survival. A tremendous amount has been learned about the numerous cellular and molecular genetic changes and the host-tumor interactions that accompany tumor development and progression. It is the goal of the field of Molecular Oncology to use this knowledge to understand cancer pathogenesis and drug action, as well as to develop more effective diagnostic and therapeutic strategies for cancer. This includes preventative strategies as well as approaches to treat metastases. With the availability of the human genome sequence and genomic and proteomic approaches, a wealth of tools and resources are generating even more information. The challenge will be to make biological sense out of the information, to develop appropriate models and hypotheses and to translate information for the clinicians and the benefit of their patients. Cancer Biology & Therapy aims to publish original research on the molecular basis of cancer, including articles with translational relevance to diagnosis or therapy. We will include timely reviews covering the broad scope of the journal. The journal will also publish op-ed pieces and meeting reports of interest. The goal is to foster communication and rapid exchange of information through timely publication of important results using traditional as well as electronic formats. The journal and the outstanding Editorial Board will strive to maintain the highest standards for excellence in all activities to generate a valuable resource.
