Our data clearly suggest that the expression of lncRNA NEAT1 and MALAT1 was significantly higher (p< 0.05, Figure 5a, b), while the expression of RAD51-AS1 and SNHG22 was significantly lower in TAO patients than in healthy individuals (p< 0.05, Figure 5c, d). Here, RAD51 is linked to thromboangiitis obliterans.
