Microarray screening of differentially expressed genes after up-regulating miR-205 or down-regulating miR-141 in cervical cancer cells

Cervical cancer is one of the most common gynecological malignancies. However,studies on the expression and molecular mechanism of miR-205 and miR-141 in CC are insufficient recently. Expression profile microarray with 21329 Oligo DNA were used to detect the expression of mRNAs in miR-205 up-regulated or miR-141 down-regulated HeLa and SiHa cells and mRNAs in normal HeLa and SiHa cells. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway were performed to assess the potential pathways of miR-205 in SiHa cell.Compared with normal HeLa cell, there were 38 differentially expressed genes (DEGs) in miR-205 up-regulated HeLa cell. Nine were up-regulation genes and 29 were down-regulation genes. There were 23 DEGs in miR-141 down-regulated HeLa cell. One was up-regulated and 22 were down-regulated. Compared with normal SiHa cell, there were 128 DEGs in miR-205 up-regulated SiHa cell. One hundred and three were up-regulation genes and 25 were down-regulation genes. There were 80 DEGs in miR-141 down-regulated SiHa cell. Forty two were up-regulation genes and 28 were down-regulation genes. For miR-205 up-regulated SiHa cell, GO outcome showed that \"ubiquitin-protein ligase activity\", \"MAP kinase phosphatase activity\", were the most enriched terms (P < 0.05). And in KEGG analysis, \"Cell cycle\" was notably enriched, and Smad4 in this pathway was up-regulated (P < 0.05). Expression profile microarray technology can effectively screen out DEGs in cervical cancer cells after up-regulating miR-205 or down-regulating miR-141. Which may enable us to understand the pathogenesis and lay an important foundation for the prevention and treatment of cervical cancer.
