PLAT was differentially expressed in VSMCs and vessel segment of SV and ITA (FQ RT-PCR). Differential Folds: The median ratio of gene expression in VSMCs from SV and ITA. Negative value mean that the gene was down-regulated in VSMCs from SV as comparing with ITA. PLAT i: from 21 SV and 13 ITA segments; PLAT p: from 12 paired SV and ITA segments. (** P < 0.001; * P = 0.028).
