Effects of Huang-Lian-Jie-Du-Decotion containing serum on expressions of autophagy related gene in macrophages / 中国免疫学杂志

ABSTRACT

Objective:To investigate the effects of Huang-Lian-Jie-Du-Decotion containing serum for the autophagy of RAM264.7 macrophages ,and to explore its possible anti-atherosclerosis mechanism .Methods:The SD rats were intervened with large , middle and small dose Huang-Lian-Jie-Du-Decotion to prepare containing drug serum .Cell proliferation was tested by MTT assay .The gene and protein expressions of Beclin 1, mTOR was assessed by fluorescent quantitative PCR and Western blot method .Results:Compared with the normal serum group ,Huang-Lian-Jie-Du-Decotion containing serum enhanced expression of the mRNA and protein level of Beclin1,and decreased the expression of mTOR and p-mTOR(P<0.05 or P<0.01).Conclusion:Huang-Lian-Jie-Du-Decotion containing serum could regulate the expressions of Beclin 1 and mTOR.These might be one of the mechanisms for preventing atheroscle-rosis.
