Effect of PM2.5 on the expression of miR-16-1-3p and Twist1 in SMMC-7721 cells
(A) Expression of miR-16-1-3p in PM2.5 treated cells and un-treated cells was detected using RT-qPCR. (B) Expression of Twist1 in PM2.5 treated cells and un-treated cells was detected using RT-qPCR. (C) Expression of Twist1 in PM2.5 treated cells and un-treated cells was detected using WB. Results were normalized with the level of U6 control. Data are mean ± SD. *, p < 0.05, **, p < 0.01.
