Zhao's Weitiao No 3 inhibits tumor growth in gastric cancer-bearing nude mice

Purpose: To investigate the effect of Zhao's Weitiao No. 3 (ZW3) on the progression of gastric cancer (GC) in mice, and to determine its effects on the proliferation and apoptosis of gastric cancer tissues. Methods: Tumor growth in vivo was used to determine the effect of ZW3 (15, 30, and 60 mg/kg) on GC growth in mice. Immunohistochemical and terminal deoxynucleotidyl transferase-mediated dUTP nick -end labeling assays were conducted to evaluate the effects of ZW3 on the proliferation and apoptosis of mouse GC tissues, while quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and immunoblot assays were conducted to determine its effects on GC cell apoptosis.Results: ZW3 inhibited tumor growth in tumor-bearing mice, suppressed the expression of proliferation -related proteins (p < 0.001), increased the apoptosis of tumor cells in tumor-bearing mice (p < 0.001), and suppressed the expression of apoptosis-related proteins in mouse tumor tissues (p < 0.001).Conclusion: Thus, ZW3 is a potential drug for the management of GC. However, further investigations are required to determine its full potential.
