When lncRNA-NC (group A), H19-sh (group B), and H19-sh+PI3K-inhibition (group C) were subcutaneously injected into the nude mice, the tumor volume and mass of nude mice in group B increased greatly (P < 0.050) (Figures 6(a) and 6(b)), and the tumor volume and mass in group C were lower than group A (P > 0.05). This evidence concerns the gene H19 and neoplasm.
