Fig. 3From: Chemopreventive effects and anti-tumorigenic mechanisms of Actinidia arguta, known as sarunashi in Japan toward 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)- induced lung tumorigenesis in a/J mouseEffect of sar-j (a, c) and isoQ (b, d) on the mutagenicity of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) (a, b) and 1-methyl-3-nitro-1-nitrosoguanidine (MNNG) (c, d), respectively. Anti-mutagenicity was assayed with the Ames test using S. typhimurium TA1535 (circle) and YG7108 (square, broken line). Experiment was repeated twice and SD is indicated with bar (n = 3)Back to article page
