Fig. 1. The miR-361-3p expression in plasma and cell lines of MM patients and its effect on cell viability. (A) The qRT-PCR results revealed that miR-361-3p in plasma of patients with MM was remarkably down regulated. **p < 0.001 vs. normal. (B) miR-361-3p in MM cell lines was down regulated. **p < 0.001 vs. nP. (C-D) The expression level of miR-361-3p was up regulated in the cells transfected with miR-361-3p mimic. (E-F) The CCK-8 assay results revealed that cells transfected with miR-361-3p mimic had a lower viability. **p < 0.001 vs. mimic control.
