κ-opioid receptor stimulation alleviates rat vascular smooth muscle cell calcification via PFKFB3-lactate signaling

Effects of κ-OR stimulation on osteogenic protein expression in VSMCs treated with β-GP. (A) Representative blot images of osteogenic differentiation-associated proteins. (B) Quantitative analysis of RUN2 protein expression using densitometry. (C) Quantitative analysis of BMP2 protein expression using densitometry. (D) Quantitative analysis of SM22a protein expression using densitometry. U, U50,488H; β-GP, β-Glycerophosphate disodium salt pentahydrate; N, nor-BNI; Data obtained from quantitative densitometry were presented as means ± SEM. n=4 in each group. *P **P #P ##P $P $$P
