SNHG22 and thromboangiitis obliterans: In order to validate the results of our RNA sequencing data from TAO patients and healthy control RNA samples, two upregulated lncRNAs (NEAT1 and MALAT1) and miRNAs (miR-3124-5p and miR-33a-3p), as well as two downregulated lncRNAs (RAD51-AS1, SNHG22) and miRNAs (miR-1-3p, miR-6786-3p), were chosen for RT-qPCR verification.
