A. Down-regulation of miR-146a and miR-146b expression in TAMR-MCF-7 cells. miR-146a and miR-146b expression in MCF-7 and TAMR-MCF-7 cells were determined by using miScript PCR kit with miScript primers specific for mature miR-146a and miR-146b. Samples were normalized to small nRNA U6. B. Effects of miR-146a and miR-146b mimics on the miR-146a/b expression in TAMR-MCF-7 cells. TAMR-MCF-7 cells were cultured in 6 wells plate and then transfected with miR-146a or miR-146b mimics for 36 h (120 pmole/well). miR-146a and miR-146b levels were determined by using miScript PCR kit with miScript primers specific for mature miR-146a and miR-146b. Samples were normalized to small nRNA U6. C. Effects of miR-146a/b mimic on NF-κB activity and MAT2A protein expression in TAMR-MCF-7 cells. TAMR-MCF-7 cells were cultured in 6 wells plate and then transfected with miR-146a or miR-146b mimics (120 pmole/well) for 36 h and immunoblottings were performed. The data were confirmed by two independent experiments. D. Effects of miR-146b mimic on MAT2A mRNA expression in TAMR-MCF-7 cells. TAMR-MCF-7 cells were cultured in 6 wells plate and then transfected with miR-146a or miR-146b mimics (120 pmole/well) for 36 h. MAT2A mRNA levels were determined by quantitative RT-PCR. Data represent mean ± SD with 3 different samples (significant versus control mimic miR-treated TAMR-MCF-7 cells, *P < 0.05). E. miR-146b expression in T47D cells. miR-146b expression in MCF-7 and T47D cells were determined by using miScript PCR kit with miScript primers specific for mature miR-146b. Samples were normalized to small nRNA U6.
