Taoren Honghua Drug Attenuates Atherosclerosis and Plays an Anti-Inflammatory Role in ApoE Knock-Out Mice and RAW264.7 Cells.


ABSTRACT: Taoren Honghua drug is a traditional Chinese medicinal drug used to treat cardiovascular disease. The aim of the study is to investigate the effects of Taoren Honghua drug on inflammation and atherosclerosis in ApoE knock-out mice and RAW264.7 cells. ApoE knock-out mice fed with high fat diet for 8 weeks were randomly divided into five groups and then continued the high fat diet, or plus Taoren Honghua drug at concentrations of 3.63, 1.815, and 0.9075 g/ml, or plus Simvastatin at 2.57 mg/kg. RAW 264.7 cells were intervened with lipopolysaccharide or lipopolysaccharide plus different concentrations of Taoren Honghua drug. Compared to mice only with high fat diet, mice with high fat diet and Taoren Honghua drug showed lower body weight, triglyceride, cholesterol, IL-6 and TNF-?, smaller plaque sizes, less lymph vessel, and T cell contents of lymph nodes, but higher IL-10 level. In RAW264.7 cells, groups with LPS plus Taoren Honghua drug had lower IL-6 and TNF-?, but higher IL-10 than LPS group, as revealed by PCR or ELISA methods. A decrease of total or phosphorylated ERK1/2, JNK, p38, ERK5, STAT3, and AKT were detected, so was the translocation of NF-?B p65 from nuclear to cytoplasm. These results suggested that Taoren Honghua drug could attenuate atherosclerosis and play an anti-inflammatory role via MAPKs, ERK5/STAT3, and AKT/NF-?B p65 signaling pathways in ApoE knock-out mice and lipopolysaccharide-induced RAW264.7 cells.
