were purchased from the Korean Cell Line Bank and maintained in RPMI-1640 Medium
(Invitrogen) containing 10% fetal bovine serum with 5% CO2 in a
37℃ incubator. miR199a5p mimics and negative mimics were purchased from
Dharmacon. Cells were transfected with a miR-199a-5p mimic using the DharmaFECT
1 transfection reagent (Dharmacon) according to the manufacturer’s
protocol. The negative mimic was used for control purposes. After 72 h of
incubation, cells were harvested and used for extraction of total RNA or
protein.
