      In this study we have investigated the effects of a tumour suppressor microRNA, miR-214, on gene expressionin HPV-positive (CaSki) and HPV-negative cervical cancer cells (C33A) by RNA sequencing using nextgeneration sequencing. The HPV-positive and HPV-negative cervical cancer cells were either miR-214-knocked-out or miR-214-overexpressed. Gene expression analysis showed that a total of 904 genes wereupregulated and 365 genes were downregulated between HPV-positive and HPV-negative cervical cancer cellswith a fold change of ±2. Furthermore, 11 differentially expressed and relevant genes (TNFAIP3, RAB25,MET, CYP1B1, NDRG1, CD24, LOXL2, CD44, PMS2, LATS1 and MDM1) which showed a fold change of ±5were selected to confirm by real-time PCR. This study represents the first report of miR-214 on global geneexpression in the context of HPV.
