The aim of this study is to analyze gene expression data to identify key genes and pathways associated with resistance to platinum-based chemotherapy in epithelial ovarian cancer (EOC) and to improve clinical treatment strategies. The gene expression data set was downloaded from Gene Expression Omnibus and included 12 chemotherapy-resistant EOC samples and 16 chemotherapy-sensitive EOC samples. A differential analysis was performed to screen out differentially expressed genes (DEGs).
Epithelial ovarian cancer
MicroRNAs (miRNAs) are a family of small non-coding RNAs (approximately 21-23 nt long) that can target genes for either degradation of mRNA or inhibition of translation. miRNAs have not been comprehensively studied in human epithelial ovarian carcinoma (EOC). MicroRNA-630 (miR-630) has been frequently observed to be aberrantly expressed in various types of tumors. The present study explored the functions of miR-630 in the proliferation, apoptosis, chemosensitivity, and invasion of EOC.
