| Objective To explore the potential role and regulatory mechanism of microRNA (miR)-30d-5p in pancreatic adenocarci. noma (PAAD).Methods A total of 35 surgical cases of pancreatic cancer patients were selected from Xinjiang Uygur Autonomous Re.gion People's Hospital between December 2016 and January 2019 to investigate the immediate gain of pancreatic tumor tissue and ad.jacent carcinoma tissue. Real-time quantitative PCR was employed to detect the expression level of miR-30d-5p in pancreatic cancer tissues and cells. The effects of miR-30d-5p on cell proliferation, migration, invasion, and apoptosis were assessed using cell count. ing kit-8 (CCK-8), colony formation assay, transwell assay, and flow cytometry. Luciferase assay and Western blot analysis were con.ducted to evaluate the regulatory effect of miR-30d-5p on ABCB5 expression. Furthermore, a nude mouse tumor model was established to verify the impact of miR-30d-5p on tumor growth by measuring tumor weight and volume. Hematoxylin and eosin staining was per.formed for histological examination.Results Compared with adjacent tissues (1.03±0.17) and normal cells (0.98±0.18), the expression of miR-30d-5p in pancreatic cancer tissues (0.35±0.08) and cells (0.63±0.08, 0.23±0.07, 0.48±0 .07, and 0.31 ± 005) was significantly decreased (P<0.05); overexpression of miR-30d-5p inhibited the vitality, migration, and invasion of tumor cells while promoting cell apoptosis with statistical significance (P<0.05); inhibition of ABCB5 expression suppressed cell vitality, migration, invasion, and in.duced apoptosis in pancreatic cancer cells with statistical significance (P<0.05); in vivo experiments demonstrated that the miR-30d-5p group could inhibit tumor growth with statistical significance (P<0.05).Conclusion MiR-30d-5p affects pancreatic cancer cell prolif.eration, migration, invasion, and apoptosis by targeting ABCB5. It may serve as a potential prognostic biomarker and target for targetedtherapy in PC patients. |
