Objectives:This study is to investigate the effects of new anti-tumor formular(NAF)on expression of PCNA,P21 ras and NF-KB P65 in liver precancerous lesions of HBV large envelope transgenic mice injected by aflatoxin ...Objectives:This study is to investigate the effects of new anti-tumor formular(NAF)on expression of PCNA,P21 ras and NF-KB P65 in liver precancerous lesions of HBV large envelope transgenic mice injected by aflatoxin B1(AFB1).Methods:The precancerous HBV large envelope transgenic mouse injected by AFB1 liver model was used.Mice was given water,NAF concentrated water solution throughout the whole experiment(48 weeks).PCNA,P21 ras and NF-KB P65 protein expression were detected by immunohistochemical method.Results: PCNA,P21 ras and NF-KB P65 expressions were significantly inhibited by NAF treatment.Conclusion NAF inhibited PCNA,P21 ras and NF-KB P65 protein expressions,therefore,NAF could show obvious effects on protecting against synergistic hepatoearcinogenesis of HBV and AFB1.展开更多
