Abstract

The dysregulation of lncRNA TMPO antisense RNA 1 (TMPO‑AS1) has been detected in various malignant tumors. However, the role of lncRNA TMPO‑AS1 remains unclear in pancreatic carcinoma. The present study aimed to elucidate the functional mechanism of TMPO‑AS1 in pancreatic carcinoma. In the present study, RT‑qPCR, western blotting, MTT, Transwell, luciferase reporter and xenograft assays were used to investigate the role of lncRNA TMPO‑AS1 in pancreatic carcinoma. Upregulation of lncRNA TMPO‑AS1 was revealed in pancreatic carcinoma tissues and cells. Furthermore, knockdown of TMPO‑AS1 restrained cell proliferation and motility in pancreatic carcinoma. In addition, microRNA (miR)‑383‑5p acted as a ‘sponge’ for lncRNA TMPO‑AS1. The expression levels of lncRNA TMPO‑AS1 and miR‑383‑5p were mutually inhibited in pancreatic carcinoma. Moreover, miR‑383‑5p was revealed to directly target SRY‑related high‑mobility group box 11 (SOX11). Notably, SOX11 could promote the occurrence of pancreatic carcinoma by interacting with the lncRNA TMPO‑AS1/miR‑383‑5p axis. In conclusion, upregulation of lncRNA TMPO‑AS1 promoted tumor growth, cell migration and invasion in pancreatic carcinoma by downregulating miR‑383‑5p and upregulating SOX11.
