Abstract
ObjectiveTo investigate the effect of asiatic acid (AA) on the differentiated human neuroblastoma SH-SY5Y cells cytotoxic-induced by cholesterol. MethodsHuman neuroblastoma SH-SY5Y cells were either exposed to different concentrations of AA or treated with different doses of cholesterol to reveal their responding viability by MTT assay. The selective 1 μmol/L concentration of AA was then used to test for either the protective or the recovery effects on the cells treated with 250 μmol/L concentration of cholesterol. ResultsAA has a propensity to directly increase the viability of differentiated human neuroblastoma SH-SY5Y cells. Cholesterol has significant cytotoxic effect on those cells in a concentration-dependent manner. AA has the ability to slightly recover the viability of the differentiated culture cytotoxic-induced by cholesterol but could not protect those cells from cytotoxic-induced by cholesterol. ConclusionsHigh concentrations of cholesterol were observed to be harmful to the neurons and AA had a slight effect of reducing neuronal death caused by cholesterol.
