Following the measurement of the weight of tumors, the results displayed (Figure 7B) that compared with the sh-NC group, there was an evident decrease in tumor weight in the sh-SMAD5-AS1 group (p < 0.05), and the tumor weight was lower in the miR-195 mimic group than in the mimic NC group (p < 0.05). This evidence concerns the gene SMAD5 and neoplasm.
