Figure 1. The expression of senescence-related biomarkers, lncRNA Sirt1-AS and Sirt1 in thrombosis of different severity. (A) Relative expression of lncRNA SIRT1-AS in thrombosis patients (B) Relative expression of mRNA Sirt1 in thrombosis patients. (C–E) Relative mRNA expressions of p16, p21 and p53 in thrombosis patients. Error bars represent SD. **, p < 0.01; ***, p < 0.001; ****, p < 0.0001.
