(A) Supernatant NK cell regulatory miR production of MUM2B and OCM1 cells transfected by electroporation with anti-miR-155 and anti-miR 146a compared to cells electroporated without anti-miRs (NT). Data represent mean ± SD, n = 3. *, P <0.05 vs. NT. (B) Effect of anti-miR-155 and anti-miR-146a on sensitivity of MUM2B and OCM1 cells to NK cell lysis mediated by NK-92 cells at an E:T ratio of 5:1 compared to cells electroporated without anti-miRs (NT). Data represent mean ± SD, n = 3. *, P <0.05 vs. NT. (C) Levels of melanocyte differentiation determinants of MUM2B and OCM1 cells transfected by electroporation with anti-miR-155 and anti-miR 146a compared to cells electroporated without anti-miRs (NT) cultured for 3 days in DMEM. Data represent mean ± SD, n = 3. *, P <0.05 vs. NT.
