The expression of IL-6 (A) and ABCA1 (B) mRNA in RA-VSMCs after exposure to 2U/ml thrombin was determined by RT-PCR * p < 0.05, ** p < 0.01, and ***p < 0.005. C RA-VSMCs were stimulated with ox-LDL in the presence or absence of thrombin(2U/ml). Red stain of Oil Red O denotes the foam cell positive cells. Magnification × 40
