| Outline of Final Research Achievements |
In this study, we identified miRNAs associated with the progression and metastasis of pancreatic cancer by comprehensively analyzing 2555 miRNAs in tissues at the time of diagnosis of pancreatic cancer by ultrasound endoscopic puncture-aspiration (EUS-FNA).
We found that miR-3180 and miR-4687-3p were enhanced in Stage IV as compared with Stage II, III (Fig. 1). In addition, when comparing patients with liver metastasis (n=23) and without liver metastasis (n=18), miR-4687-3p and miR-3940 were enhanced in liver metastasis, while miR-192 and miR-200b were attenuated (Fig. 2). In addition, miR-4687-3p and miR-4442 were enhanced and miR-1246 and miR-451 were decreased in patients with lung metastasis (7 cases) compared with those without lung metastasis (18 cases) (Fig. 3).These results suggest that miRNAs are associated with the progression and metastasis of pancreatic cancer.
