Figure 5From: δ-Aminolevulinic acid cytotoxic effects on human hepatocarcinoma cell lines p53 mRNA expression in HEP G2 cells under ALA treatment. Total RNA was isolated after treatment of cells with ALA (0–5 mM) during 24 h and hybridized with cDNA p53 specific probe and normalized relative to GAPDH. Intensity of bands were analysed with ImageMaster.Back to article page
