Abstract:
Objective To explore the effect of Xinwei Granules on cell proliferation in rats with precancerous lesions of gastric cancer based on CyclinD1-CDK4/6-P16 pathway.Methods 180 Wistar rats were randomly divided into 6 groups,30 rats in each group:blank control group(blank),model group,Weifuchun control group,Xinwei Granule(low,medium and high dose)group.The PLGC rat model was made by MNNG method.Xinwei granule low,medium and high dose group were 0.72 g·kg-1,1.44 g·kg-1,2.88 g·kg-1;weifuchun group was given 0.52 g·kg-1,once a day by intragastric administration,and the blank group and the model group were given the same amount of normal saline by intragastric administration.The experimental period was 16 weeks.After the end of the experiment,the general condition of the rats was observed,and the mRNA and protein expressions of CyclinD1,CDK4/6 and P16 in gastric mucosa were detected by RT-PCR and Western blotting.Results The activity and diet of rats in each group of Xinwei Granules and Weifuchun group were improved to varying degrees compared with the model group.Compared with the blank control group,the mRNA and protein expression levels of CyclinD1,CDK4 and CDK6 in the model group were significantly increased.The mRNA and protein expression levels of P1 6 were significantly decreased(P＜0.05).The expression levels of CyclinD1,CDK4,CDK6 mRNA and protein in Xinwei granule(low,medium and high dose)group and Weifuchun group were lower than those in model group.The mRNA and protein expression levels of P16 were significantly increased(P＜0.05),and the effect of Xinwei granule medium dose group was the most significant.Conclusion Xinwei granules participate in the regulation of cell cycle through the CyclinD1-CDK4/6-P16 pathway,thereby inhibiting the proliferation of PLGC cells.
