Fig. 6From: Antiproliferative and proapoptotic effects of DODAC/synthetic phosphoethanolamine on hepatocellular carcinoma cellsAnalysis of protein expression in Hepa1c1c7 cells. The expression of proteins was quantified by flow cytometry after 24 h of treatment with PHO-S, DODAC and DODAC/PHO-S. The bar graphs show the level of expression of TRAIL - DR4 receptor (a); protein caspase 3 (b); caspase-8 protein (c); Free cytochrome c (d); protein Bax (e); protein Bcl-2 (f). Values are expressed as a mean ± SD standard deviation of three independent experiments. Level of significance * P < 0.05, ** p < 0.01 and *** p < 0.001Back to article page
