Fig. 4From: Weight of evidence approach using a TK gene mutation assay with human TK6 cells for follow-up of positive results in Ames tests: a collaborative study by MMS/JEMSProtein expression levels of the intrinsic apoptotic signaling pathway in response to oxidative stress by the 24 h treatment of 4-nitroanthranilic acid. PDK1, SOD2, DIABLO that belong to GO:0008631 ~ intrinsic apoptotic signaling pathway in response to oxidative stress were drastically elevated only at the 24 h treatment of 4-nitroanthranilic acid, especially in the 800 μg/mL groupBack to article page
