Figure 6. The successful transfection of MEG3 siRNA, which was validated by the evidently reduced expression of MEG3 (A), promoted the expression of miR-181b (B) and repressed the expression of TNF-α mRNA (C) and protein (D). Moreover, the successful transfection of miR-181b precursors, which was validated by the significantly promoted miR-181b expression (B), suppressed the expression of MEG3 (A), TNF-α mRNA (C) and protein (D) (* P value < 0.05 vs. NC group; 3 biological repeats).
