miR-140-3p was poorly expressed in tissues and cells of GC and was related to the prognosis and clinicopathologic features of patients with GC. A, B The expression of miR-140-3p in gastric adenocarcinoma was predicted by the Starbase and UALCAN database. C The expression of miR-140-3p in GC tissues and adjacent tissues was detected using RT-qPCR. D The expression of miR-140-3p in GC cell lines was detected using RT-qPCR. E The relation between miR-140-3p and the prognosis in patients with GC was analyzed with Kaplan–Meier Plotter. F The relation between the expression of miR-140-3p in GC tissues and prognosis in patients was analyzed by Kaplan–Meier. N = 60. The cell experiment was repeated 3 times independently. Data in D were presented as mean ± standard deviation. Comparisons between two panels in C were analyzed using the t-test. Comparisons of data in F were performed using the Log Rank test. Comparisons of data in D were performed using one-way ANOVA, followed by Tukey's multiple comparisons test. ^**p < 0.01
