Figure 1. Specific siRNA effectively knockdown BMPRII protein without affecting BMPRIa protein in PASMCs.

Images showing the blots of BMPRII protein for 48 h or 108 h (A) and BMPRIa protein relative to α-actin as detected by Western blotting in PASMCs treated with BMPRII small interference siRNA or non-targeting (NT) control siRNA for 48 h (C). Bar values are means ± SEM (n  =  4 for each group). *P <0.01 vs. respective siNT control (B and D).
