Fig. 5From: Phenolics from Barleria cristata var. Alba as carcinogenesis blockers against menadione cytotoxicity through induction and protection of quinone reductaseConcentration -dependent upregulation of NQO1 protein expression by Compound 2 in Hepa1c1c7 cells. Cells were cultured and assayed using Western blotting (a) as described in the Experimental section. Densitometric determination (b) of the fold of NQO1 induction over DMSO control (ctrl) was performed using Image Studio LiteBack to article page
