lncRNA and mRNA expression signatures in OVCAR3 cells: control vs. miR-200a transfected

To further development of the effects of miR-200a in ovarian cancer OVCAR3 cells，we have employed lncRNA and mRNA microarray as a discovery platform to identify lncRNA and mRNA expression in miR-200a overexpressing ovarian cancer cells. OVCAR3 cells were transfected with lentiviral vector with eGFP, encoding miR-200a and negative control vector (LV- miR-200a and LV-CON,) by using polybrene. The dysregulation of miR-200a was confirmed by using RT-PCR. RNA was extracted and detected by a lncRNA and mRNA microarray in LV-miR-200a and LV-CON OVCAR3 cells. The different expression of lncRNA and mRNA in LV-miR-200a and LV-CON OVCAR3 cells was analyzed to explore the mechanism that miR-200a affect ovarain cancer cells. miR-200a overexpression induced lncRNA and mRNA expression in OVCAR3 cells was measured in LV-miR-200a and LV-CON groups. 3 control replicates at each group.
