Abstract

Multiple previous studies have demonstrated that the dysregulation of microRNAs (miRNAs) is implicated in the occurrence and development of pancreatic cancer. Therefore, a further characterisation of deregulated miRNAs in pancreatic cancer may provide novel insight into the oncogenesis and progression of pancreatic cancer, which may facilitate the identification of effective therapeutic targets for treating patients with this disease. In the present study, reverse transcription‑quantitative polymerase chain reaction analysis demonstrated that the expression level of miRNA‑584‑5p (miR‑584) was significantly decreased in pancreatic cancer tissues and cell lines. It was demonstrated that restoration of miR‑584 expression significantly suppressed the proliferative and invasive ability of pancreatic cancer cells. Bioinformatics analysis predicted that cyclin D1 (CCND1) was a putative target of miR‑584. Subsequent experiments demonstrated that CCND1 was a direct target gene of miR‑584 in pancreatic cancer cells. Furthermore, the inhibition of CCND1 mimicked the suppressive effect of miR‑584 overexpression in pancreatic cancer cells. The restoration of CCND1 expression significantly abolished the inhibitory effects of miR‑584 overexpression on pancreatic cancer cells. Collectively, the present results demonstrated that miR‑584 inhibited the development of pancreatic cancer by directly targeting CCND1, suggesting that this miRNA may represent a potential therapeutic target for this fatal disease.
