Cells were seeded at 250,000 cells/well in 6 well-plate or at 1,500,000 cells/100mm dish. After 24 h, cells were transfected with one of the RNA oligonucleotides (
Anti-miR-9, anti-miR-335, anti-miR-338-3p, Negative Control (NC)-anti-miR, pre-miR-338-3p,
pre-miR-335,
pre-miR-335* or Negative Control (NC)-pre-miR; Applied Biosystems) at the 50 nM final concentration, using
Lipofectamine 2000 reagent (Invitrogen) and Opti-MEM medium according to the manufacturer’s instructions. After 6 h of transfection, the medium was changed to fresh growth medium. Cells were collected after 48 h of transfection.
