1.Effect of ferulic acid on cholesterol efflux in macrophage foam cell formation and potential mechanism.
China Journal of Chinese Materia Medica 2015;40(3):533-537
The formation of macrophage-derived foam cells is a typical feature of atherosclerosis (AS). Reverse cholesterol efflux (RCT) is one of important factors for the formation of macrophage foam cells. In this study, macrophage form cells were induced by oxidized low density lipoprotein (ox-LDL) and then treated with different concentrations of ferulic acid, so as to observe the effect of ferulic acid on the intracellular lipid metabolism in the ox-LDL-induced macrophage foam cell formation, the cholesterol efflux and the mRNA expression and protein levels of ATP binding cassette transporter A1 (ABCA1) and ATP binding cassette transporter G1 (ABCG1) that mediate cholesterol efflux, and discuss the potential mechanism of ferulic acid in resisting AS. According to the findings, compared with the control group, the ox-LDL-treated group showed significant increase in intracellular lipid content, especially for the cholesterol content; whereas the intracellular lipid accumulation markedly decreased, after the treatment with ferulic acid. The data also demonstrated that the mRNA and protein expressions of ABCA1 and ABCG1 significantly increased after macrophage foam cells were treated with different concentrations of ferulic acid. In summary, ferulic acid may show the anti-atherosclerosis effect by increasing the surface ABCA1 and ABCG1 expressions of macrophage form cells and promoting cholesterol efflux.

Objective To investigate the expression of hypoxia inducible factor 1α (HIF-1α) and glucose transporter 1 (GLUT1) in lung adenocarcinoma and its correlation with tumor metastasis. Methods SP immunohistochemistry was used to detect GLUT1 and HIF-1α protein expression in 125 lung adenocarcinoma, including 41 cases without metastasis, 38 cases with lymphatic metastasis and 46 cases with brain metastasis. The correlation of GLUT1 and HIF-1α in lung adenocarcinoma metastasis was analyzed by using x 2 test and Pearson correlation analysis. Results Most lung adenocarcinoma were histologically heterogeneous, which contained more than one adenocarcinoma type. 73.2 % (30/41) cases were acinar predominant adenocarcinoma in lung adenocarcinoma without metastasis; 53.6 % (15/38) cases were acinar predominant adenocarcinoma and 26.3 % (10/38) cases were solid predominant adenocarcinoma in lung adenocarcinoma with lymphatic metastasis; 47.8 % (22/46) cases were papillary predominant adenocarcinoma and 34.8 % (16/46) cases were solid predominant adenocarcinoma in lung adenocarcinoma with brain metastases. The expression level of GLUT1 and HIF-1α in lung adenocarcinoma with lymphatic metastasis group was higher than that of the group without tumor metastasis (P< 0.05); the expression of GLUT1 and HIF-1α were positively correlated (r=0.407, P=0.000). Conclusions Papillary adenocarcinoma is the most histological type in lung adenocarcinoma with brain metastasis, suggesting that papillary adenocarcinoma is more prone to brain metastasis. The expression of GLUT1 and HIF-1α play an important role in lymph node metastasis and brain metastasis of lung adenocarcinoma.
