Expression profile of tRNA‑derived fragments and their potential roles in human varicose veins.

ABSTRACT: Varicose veins (VVs) is a common disease presenting with chronic venous insufficiency. tRNA‑derived fragments (tRFs) are associated with a variety of pathological conditions. However, the functions of tRFs in VVs have not been elucidated to date. The present study aimed to identify the key tRFs and investigate their potential roles in VVs. Small RNA sequencing (RNA‑seq) was performed to investigate the expression of tRFs in tissues of patients with VVs and their matched adjacent normal veins tissues (ANVs). Reverse transcription‑quantitative PCR (RT‑qPCR) was used to confirm the differential expression of tRFs. A total of 13,789 tRFs were identified by small RNA‑seq, including 45 differentially expressed tRFs (DETs), which comprised 14 upregulated and 31 downregulated tRFs in VV tissues co
