Deskripsi

<h4>Background</h4>The prognosis of pancreatic cancer (PC) is relatively dismal due to the lack of effective therapy. In this study, we explored the specific functions and molecular mechanisms of miR-107 to uncover effective therapeutic targets for PC.<h4>Method</h4>The miR-107 expression in PC cell lines was assessed via quantitative real-time polymerase chain reaction (qRT-PCR). Besides, online bioinformatics analysis was adopted to predict the underlying targets of miR-107. Meanwhile, TCGA database was employed to explore the prognosis of PC patients. In addition, MTT and transwell assays were conducted to explore the PC cells' biological functions.<h4>Result</h4>MiR-107 was remarkably increased in PC cells which could promote the proliferation, invasion and migration of PC cells. In addition, miR-107 could directly down-regulate TGFBR3 expression through binding to TGFBR3 3'UTR. Survival analysis from TCGA suggested that PC patients with higher miR-107 expression was significantly involved in poorer prognosis.<h4>Conclusion</h4>We concluded that miR-107 promoted proliferation, invasion and migration of PC cells via targeting TGFBR3, which may provide novel underlying therapeutic targets.
