摘要

目的

探究不同时期、疗程和剂量的孕期阿奇霉素暴露(PAzE)对胎肝发育和功能的影响。

方法

孕鼠灌胃给予不同时期(孕中、晚期)、疗程(单疗程或多疗程)和剂量(50或200 mg·kg

) PAzE，检测胎肝质量以及增殖、分化、凋亡和糖脂代谢功能基因表达。

结果

在雌性，PAzE抑制胎鼠肝脏增殖和分化相关基因表达，并促进凋亡相关基因表达。在雄性，PAzE主要促进胎鼠肝脏增殖和分化相关基因的表达，对凋亡无显著影响。进一步，PAzE抑制雌、雄胎鼠肝脏的糖异生功能，增强其甘油三酯、胆固醇和胆汁酸合成功能。此外，PAzE促进雌性胎鼠肝脏雌激素受体表达，并抑制雄性胎鼠雄激素受体表达。上述改变在孕晚期、多疗程和高剂量下更显著。

结论

PAzE可以性别差异性地影响胎肝发育，抑制雌、雄胎鼠肝脏的糖异生功能，增强其脂质合成功能，上述改变具有时期、疗程和剂量差异。

Abstract

Objective

To investigate the effects of prenatal azithromycin exposure (PAzE) on fetal mouse liver development and function at different stages

courses

and doses.

Methods

Pregnant mice were exposed to azithromycin during pregnancy at different stages (middle/late pregnancy)

courses (single course/multiple courses)

and doses (50 or 200 mg·kg

-1

·d

-1

) by intragastric administration. Fetal liver weight and mRNA expression of genes related to proliferation

differentiation

apoptosis

and glucose and lipid metabolism were detected.

Results

In female mice

PAzE inhibited the expression of genes related to liver proliferation and differentiation

and promoted the expression of genes related to apoptosis. In male mice

PAzE mainly promoted the expression of genes related to liver proliferation and differentiation

but exerted no significant effect on apoptosis. Furthermore

PAzE inhibited gluconeogenesis and enhanced the synthesis of triglyceride

cholesterol

and bile acid in the liver of female and male fetal mice. In addition

PAzE promoted the expression of estrogen receptor in the liver of female fetal mice and inhibited the expression of androgen receptor in male fetal mice. These changes were more significant in late pregnancy

with multiple courses and high doses.

Conclusion

PAzE could exert sex⁃specific effects on fetal liver development

inhibit gluconeogenesis in the liver of female and male fetal mice

and enhance their lipid synthesis function. These effects differ based on stages

courses

and doses.
