Figure Lengend Snippet: Fig. 6. (A) Western blot analyses of Bax, Bcl-2, PCNA and caspase-3 in testes of adult mice offspring at PND 75 of lactating dams who were exposed to PTU and BDE-209 (500 and 700 mg/kg BW) in comparison to vehicle- treated controls. All protein expression levels were normalized relative to α-tubulin loading control. (B) The densitometric data of Bax, Bcl- 2, PCNA and caspase-3 are presented as the mean of integrated relative density value (IRDV)±S.E.M. of triplicate blots. Representa tive testicular sections showing TUNEL-positive cells (arrows) in seminiferous tubules in adult mice testes of lactating dams who were exposed to PTU (C), vehicle (D) and BDE-209 (E: 500 mg/kg BW; F: 700 mg/kg BW). Scale bar: 50 µm (C-F). (G) Histogram shows an increase in the number of TUNEL-positive cells in testes of PTU and BDE-209-exposed offspring at PND 75. Values are mean ±S.E.M. *Significantly different from controls (p < 0.05) by ANOVA followed by Newman- Keuls’multiple range test.
