摘要: 目的:研究头孢曲松及其杂质对斑马鱼肝脏的毒性。方法:选用受精后72 h的野生型斑马鱼和肝脏特异性荧光标记的转基因斑马鱼作为实验动物。分别用不同浓度的(0、1、2、5 mmol/L)头孢曲松和杂质A、B、C、D,以及不同浓度的(0、0.1、0.5、1 mmol/L)杂质E处理两种幼鱼2 d后,观察幼鱼肝脏形态和肝脏荧光强度;采用整体油红O染色观察野生型斑马鱼肝脏脂肪含量变化;进一步利用转录组测序技术对各受试物处理组斑马鱼进行转录组测序,筛选差异表达基因,并进行信号通路富集分析。结果:活体观察显示,与对照组比较,头孢曲松及其杂质A和C主要使斑马鱼幼鱼肝脏区扩大或荧光强度增强(P<0.05或0.01),杂质B、D和E主要使幼鱼肝脏区减小或荧光强度减弱(P<0.05或0.01)。整体油红O染色显示头孢曲松及其杂质均能导致斑马鱼肝脏脂肪堆积。头孢曲松给药组利用转录组测序筛选出差异表达基因共735个,杂质A组共237个,杂质C组共237个。KEGG通路分析提示各受试物组差异表达基因主要富集通路不同。头孢曲松差异基因主要富集于代谢通路和卟啉等通路中;杂质A组差异基因主要富集于色氨酸代谢等信号通路;杂质C组差异基因主要富集于钙信号通路等信号通路。结论:头孢曲松及其杂质A、B、C、D和E可导致不同程度斑马鱼肝功能发生变化,并造成肝脏组织损伤。

Abstract: OBJECTIVE: The objective of this study was to investigate the hepatotoxicity of ceftriaxone and its impurities in zebrafish. METHODS: Wild-type strain zebrafish at 72 h post-fertilization(hpf) and transgenic zebrafish Tg(fabp10a:Ds Red) with liver-specific fluorescence labeling were chosen as experimental animals.Zebrafish larvae were treated with different concentrations of ceftriaxone(at concentrations of 1, 2, 5 mmol/L) and its impurities A, B, C, D and impurities E(at concentrations of 0.1, 0.5, 1 mmol/L) for 2 days. The liver morphology of wild-type zebrafish larvae and the fluorescence intensity of transgenic zebrafish larvae were observed, and the hepatotoxicity of each group was assessed by comparison with the control group. Whole-body Oil Red O staining was employed to observe changes in liver fat content. Additionally, transcriptomic sequencing was performed to detect the gene expression profiles of zebrafish in each treatment group. Differential expression genes were screened(735 differential genes in ceftriaxone group, 237 in impurity A group and 237 in impurity C group), and Gene and Genomes(KEGG) pathway enrichment analysis was conducted. RESULTS: Ceftriaxone and impurities A and C caused an enlargement of the zebrafish liver region or an increase in fluorescence intensity compared to the control group(P<0.05 or 0.01). Impurities B, D, and E primarily resulted in a reduction of the liver region or a decrease in fluorescence intensity compared to the control group(P<0.05 or 0.01). Overall Oil Red O stain assays indicated that both ceftriaxone and its impurities could cause an increase in liver fat. Differential gene expression was observed in each treatment group through transcriptome sequencing.KEGG pathway analysis revealed different pathway enrichments in each group. Genes related to ceftriaxone were mainly enriched in 10 pathways, including metabolism. Genes related to impurity A were mainly enriched in signaling pathways such as tryptophan metabolism. Genes related to impurity C were mainly enriched in signaling pathways, including calcium signaling. CONCLUSION: The study provides insights into the hepatotoxic effects of ceftriaxone and its impurities in zebrafish, demonstrating varied impacts on liver morphology, fluorescence intensity, and gene expression profiles. The findings highlight potential pathways through which these substances may induce hepatotoxicity.
