Molecular Mechanism of WWOX Inhibiting the Development of Esophageal Cancer by Inhibiting Hippo Signaling Pathway.
With the emergence of combined surgical treatments, complemented by radiotherapy and chemotherapy, survival rates for esophageal cancer patients have improved, but the overall 5-year survival rate remains low. Therefore, there is an urgent need for further research into the pathogenesis of esophageal cancer and the development of effective prevention, diagnosis, and treatment methods. We initially utilized the GeneCards and DisGeNET databases to identify the esophageal cancer-associated gene WWOX (WW domain containing oxidoreductase). Subsequently, we employed RT-qPCR (Reverse transcription-quantitative PCR) and WB (western blot) to investigate the differential expression of WWOX in HEEC (human esophageal endotheliocytes) and various ESCC (esophageal squamous cell carcinoma) cell lines. We further evaluated alterations in cell proliferation, migration and apoptosis via CCK8 (cell counting kit-8) and clonal formation, Transwell assays and flow cytometry. Additionally, we investigated changes in protein expressions related to the Hippo signaling pathway (YAP/TEAD) through RT-qPCR and WB. Lastly, to further elucidate the regulatory mechanism of WWOX in ESCC, we performed exogenous YAP rescue experiments in ESCC cells with WWOX overexpression to investigate the alterations in apoptosis and proliferation. Results indicated that the expression of WWOX in ESCC was significantly downregulated. Subsequently, upon overexpression of WWOX, ESCC cell proliferation and migration decreased, while apoptosis increased. Additionally, the expression of YAP and TEAD were reduced. However, the sustained overexpression of YAP attenuated the inhibitory effects of WWOX on ESCC cell malignancy. In conclusion, WWOX exerts inhibitory effects on the proliferation and migration of ESCC and promotes apoptosis by suppressing the Hippo signaling pathway. These findings highlight the potential of WWOX as a novel target for the diagnosis and treatment of esophageal cancer.
期刊介绍:
Biochemical Genetics welcomes original manuscripts that address and test clear scientific hypotheses, are directed to a broad scientific audience, and clearly contribute to the advancement of the field through the use of sound sampling or experimental design, reliable analytical methodologies and robust statistical analyses.
Although studies focusing on particular regions and target organisms are welcome, it is not the journal’s goal to publish essentially descriptive studies that provide results with narrow applicability, or are based on very small samples or pseudoreplication.
Rather, Biochemical Genetics welcomes review articles that go beyond summarizing previous publications and create added value through the systematic analysis and critique of the current state of knowledge or by conducting meta-analyses.
Methodological articles are also within the scope of Biological Genetics, particularly when new laboratory techniques or computational approaches are fully described and thoroughly compared with the existing benchmark methods.
Biochemical Genetics welcomes articles on the following topics: Genomics; Proteomics; Population genetics; Phylogenetics; Metagenomics; Microbial genetics; Genetics and evolution of wild and cultivated plants; Animal genetics and evolution; Human genetics and evolution; Genetic disorders; Genetic markers of diseases; Gene technology and therapy; Experimental and analytical methods; Statistical and computational methods.
