Figure 6
The mRNA expression and protein expression of Smad3 in injured arteries 14 days after balloon angioplasty. (a) qRT-PCR analysis of Smad3 mRNA expression, GAPDH served as internal standard. n = 3. (b) Western blot analysis of Smad3 protein expression, GAPDH served as internal standard. Each bar shows as mean ± SD. P < 0.001.
