Yangzheng Sanjie decoction regulates proliferation and apoptosis of gastric cancer cells by enhancing let-7a expression

Figure 6 Expression levels of let-7a and c-Myc in gastric cancer tissues. A-C: Expression of let-7a miRNA (ISH, × 400): high in distal normal gastric tissues (A), moderate in matched para-carcinoma tissues (B) and low in GC tissues (C). D-F: Expression of c-Myc protein (IHC, × 400): low in distal normal tissues (D), moderate in adjacent tissues (E) and high in GC tissues (F). GC: Gastric cancer; ISH: In situ hybridization; IHC: Immunohistochemistry.
