英文摘要To examine the effects of BaP on tissue apoptosis, laboratory studies were conducted using juvenile Chinese rare minnows (Gobiocypris rarus) exposed to 1, 5, 20, and 80 mu g/L of BaP for 28 days. The post-treatment pathological findings in the liver were associated with hepatocyte swelling, karyopyknosis, and karyorrhexis. Moreover, an increase in the goblet cells in the intestine, epithelial hyperplasia of the gills and fusion of gill lamellae were observed. Significant increases in hepatocyte apoptosis using the TUNEL stain were observed in the liver tissue but not in the intestine and gills. In addition, BaP exposure significantly up-regulated the mRNA levels of cyp1a1, p53, bax, bcl-2, and caspase-9 in the liver following the 5, 20, and 80 mu g/L treatments, whereas the apaf-1 was significantly down-regulated following all treatments. Moreover, the activities of caspase 3 and caspase 8 were markedly elevated, whereas the protein expression levels of Apaf-1 were down-regulated following the 20 and 80 mu g/L treatments. Taken together, our results suggested that BaP strongly induces tissue-specific apoptosis in vivo, leading to significant pathological changes. The responsiveness of apoptotic-related genes demonstrates that BaP induced apoptosis in the liver may be through a mitochondria-independent pathway. (C) 2017 Published by Elsevier Ltd.
