MiR-200a Regulates CDK4/6 Inhibitor Effect by Targeting CDK6 in Metastatic Melanoma

Three metastatic melanoma cell lines (BD-0548-ME, DP-0574-ME and WP-0614-ME) were transfected with miR precursors: hsa-miR negative control (NC) or hsa-miR-200a-3p precursors (miR-200a). The objective of this experiment was to determine miR-200a targets in metastatic melanoma cell lines. We selected low -miR-200a expression cell lines and then we overexpressed miR-200a or NC. Finally, we compared the metastatic melanoma cell lines with miR-200a overexpression (miR-200a) to the same cell line transfected with the negative control miR (NC). Total RNA was extracted from three melanoma cell lines and RNA-Seq by using Illumina HiSeq 2500.
