Inhibition of miR-155 expression decreased the viability of PC cells in vitro. The indicated human and mouse PC cells were treated with miR-155 inhibitor or scrambled miRNA (100 nM) for 24 h and assessed for (A,C,E) miR-155 gene expression by qPCR or (B,D,F) cell viability by MTT assay. Data presented as the mean ± S.D. of each experimental group (n = 3). * p < 0.05; *** p < 0.001 (by two-tailed t test).
