Fig. 3From: Phenolics from Barleria cristata var. Alba as carcinogenesis blockers against menadione cytotoxicity through induction and protection of quinone reductaseConcentration-response curve of the toxicity of Menadione on Hepa-1c1c7 cells. Cells were cultured and treated with MD (1.5–100 μM) for 24 h and then assayed using SRB cytotoxicity assay as described in the Experimental section, each data point represents means of Octuplet well treatmentsBack to article page
