Tripterygium wilfordii multiglycoside(GTW)is a commonly used compound for the treatment of rheumatoid arthritis(RA)and immune diseases in clinical practice.However,it can induce liver injury and the mechanism of hepatotoxicity is still not clear.This study was designed to investigate GTW-induced hepatotoxicity in zebrafish larvae and explore the mechanism involved.The 72 hpf(hours post fertilization)zebrafish larvae were administered with different concentrations of GTW for three days and their mortality,malformation rate,morphological changes in the liver,transaminase levels,and histopathological changes in the liver of zebrafish larvae were detected.The reverse transcription-polymerase chain reaction(RT-PCR)was used to examine the levels of microRNA-122(miR-122)and genes related to inflammation,apoptosis,cell proliferation and liver function.The results showed that GTW increased the mortality of zebrafish larvae,while significant malformations and liver damage occurred.The main manifestations were elevated levels of alanine aminotransferase(ALT)and aspartate aminotransferase(AST),significant liver atrophy,vacuoles in liver tissue,sparse cytoplasm,and unclear hepatocyte contours.RT-PCR results showed that the expression of miR-122 significantly decreased by GTW;the mRNA levels of inflammation-related genes il1β,il6,tnfα,il10,cox2 and ptges significantly increased;the mRNA level of tgfβsignificantly decreased;the mRNA levels of apoptosis-related genes,caspase-8 and caspase-9,significantly increased;the mRNA level of bcl2 significantly decreased;the mRNA levels of cell proliferation-related genes,top2αand uhrf1,significantly reduced;the mRNA levels of liver function-related genes,alr and cyp3c1,significantly increased;and the mRNA level of cyp3a65 significantly decreased.In zebrafish,GTW can cause increased inflammation,enhanced apoptosis,decreased cell proliferation,and abnormal expression of liver function-related genes,leading to abnormal liver structure and function and resulting in hepatotoxicity. 展开更多

目的以肝脏绿色荧光转基因斑马鱼Tg(L-FABP:EGFP)为模型,研究一线抗结核药物异烟肼、吡嗪酰胺和乙胺丁醇对斑马鱼肝脏的影响以及比较其肝毒性大小。方法用不同浓度的异烟肼、吡嗪酰胺和乙胺丁醇分别处理发育至72h的斑马鱼,于加药后24、4... 目的以肝脏绿色荧光转基因斑马鱼Tg(L-FABP:EGFP)为模型,研究一线抗结核药物异烟肼、吡嗪酰胺和乙胺丁醇对斑马鱼肝脏的影响以及比较其肝毒性大小。方法用不同浓度的异烟肼、吡嗪酰胺和乙胺丁醇分别处理发育至72h的斑马鱼,于加药后24、48和72hpe(hour post-exposure)观察斑马鱼的死亡率、畸形率和肝脏形态变化情况,荧光显微镜下观察药物对斑马鱼肝脏荧光面积和荧光强度的影响。结果随着给药浓度的增加和给药时间的延长,异烟肼、吡嗪酰胺和乙胺丁醇导致斑马鱼死亡率、畸形率升高。在72hpe,与空白对照组相比,1、2.5和5mmol/L吡嗪酰胺组斑马鱼肝脏荧光面积显著下降,5mmol/L异烟肼组斑马鱼肝脏荧光面积显著下降,10、20和30mmol/L乙胺丁醇组斑马鱼肝脏荧光面积显著下降。5mmol/L浓度下,异烟肼导致斑马鱼肝脏荧光面积降低程度高于吡嗪酰胺。结论异烟肼、吡嗪酰胺和乙胺丁醇均有肝脏毒性,乙胺丁醇肝毒性最小。1和2.5mmol/L浓度下吡嗪酰胺导致斑马鱼发生肝损伤程度强于异烟肼,但5mmol/L下异烟肼肝脏损伤程度强于吡嗪酰胺,其有关机制需进一步研究。 展开更多
