维甲酸作用下胎鼠腭突发育期间母体的血浆代谢组学分析
|
Abstract:
摘要 目的:建立维甲酸诱导C57BL/6J小鼠腭裂模型,利用核磁共振技术和主成分分析方法分析胎鼠腭突发育期间孕鼠血浆的特征性代谢变化。方法:将孕鼠随机分为维甲酸实验组和植物油对照组,分别在ED12.0予孕鼠以维甲酸和植物油灌胃,在特定孕期收集孕鼠血浆样本和统计胎鼠腭裂发生率。应用核磁共振波谱仪测定一氢核磁共振波谱图和主成分分析法(PCA)描绘胎鼠腭突发育期间维甲酸作用下C57BL/6J孕鼠血浆代谢产物的变化轨迹图。结果:PCA分析结果显示腭发育期间两组孕鼠血浆代谢轨迹不同。结论:维甲酸可以延缓孕鼠胚胎发育期间血浆的代谢轨迹,说明母体环境变化与胚胎发育两者之间存在关联性
