SHTL reduces Ox-LDL-induced cellular lipid accumulations in macrophages. (a) MPMs were stimulated without or with Ox-LDL (40 μg/mL, 24 h) in the presence or absence of SHTL for 24 h. The dose-dependent lipid-reducing effect of SHTL pretreatment in MPMs was evaluated using the Oil red O (top) or DiI-Ox-LDL (bottom) stainings. Representative microscopic images (40x, ) are shown. (b) Pretreatment with SHTL for 24 h inhibited cellular lipid accumulation in THP-1-drived macrophages using flow cytometric analysis. The quantification of DiI-Ox-LDL-PE fluorescence is shown on the right. versus the Ctrl group; # versus the Ox-LDL group, .
