Abstract
Lung cancer is a malignant tumor with the highest mortality rate worldwide. Non-small cell lung cancer (NSCLC) accounts for approximately half of all lung cancer cases. Inhibin beta A (INHBA) is a ligand of the transforming growth factor-beta superfamily. This study aimed to analyze the function of INHBA in NSCLC resistance cells. Gene Expression Omnibus and The Cancer Genome Atlas databases were used to identify differentially expressed genes (DEGs) in NSCLC resistance cells and patients. DEGs were further analyzed by gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis. A colony formation assay was performed to determine cell growth. Cell migration and invasion were tested by Transwell assay. Epithelial-mesenchymal transition (EMT)-related genes were analyzed using qRT-PCR and Western blot analysis. Using bioinformatics tools, INHBA was demonstrated to be overexpressed in NSCLC resistant cells and patients. Gefitinib treatment affected NSCLC resistant cells. Additionally, INHBA silencing or X-ray treatment suppressed the growth and metastasis of NSCLC resistant cells. Moreover, the combined application of INHBA silencing and X-ray treatment enhances the therapeutic effects. Moreover, EMT has been confirmed to occur in NSCLC resistant cell lines. Both INHBA silencing and X-ray treatment inhibited EMT development. This study demonstrated that INHBA silencing ameliorates EGFR-TKI resistance and enhances the therapeutic effect of radiotherapy in NSCLC.
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.
