摘    要: 摘要: 目的: 研究在全反式维甲酸诱导小鼠神经管畸形模型中神经系统相关基因(ASH2L,HDAC4,NSPC1与DOK5)的表达变化。方法: 取8只E8.5的C57/BL6孕鼠随机分为两组:对照组(4只),模型组(4只)。对照组腹腔注射橄榄油,模型组腹腔注射全反式维甲酸;E13.5取胚胎。采用Real-time PCR检测两组小鼠脑和脊髓中ASH2L,HDAC4,NSPC1与DOK5的mRNA表达;采用Western Blotting技术检测两组小鼠脑和脊髓中ASH2L,HDAC4,NSPC1与DOK5的蛋白表达情况。结果:全反式维甲酸可诱导小鼠出现典型神经管畸形;与对照组相比,全反式维甲酸处理组的致畸胚胎脑和脊髓中,ASH2L HDAC4, NSPC1和DOK5的mRNA表达有所下降(P<0.05);同时这些基因的蛋白水平也显著下降 (P<0.05)。结论:ASH2L,HDAC4,NSPC1和DOK5可能是抑制全反式维甲酸致神经管畸形的潜在基因。

关 键 词:全反式维甲酸  ASH2L,HDAC4,NSPC1与DOK5  神经管畸形

Abstract:Objective To study the expression of four nervous system related genes:ASH 2 L,HDAC4,NSPC1 and DOK5 in the all-trans retinoic acid induced mouse neural tube defect model.Methods Divide eight E8.5 C57/BL6 pregnant mice randomly into two groups:control group and experimental group.Control group was intraperitoneal injected by olive oil;the experimental group was intraperitoneal injected by all trans retinoic acid which was dissolved in olive oil;Embryos were taken at E13.5.The mRNA expression of ASH 2 L,HDAC4,NSPC1 and DOK5 in mouse brain and spinal cord was detected by real-time PCR;the protein expression was detected by Western blot.Results All trans retinoic acid can induce a typical neural tube defects in mice.Compared with the control group,the expression of mRNA and protein declined in fetal mice brain and spinal cord which is treated with all trans RA(P<0.05).Conclusions ASH 2 L,HDAC4,NSPC1 and DOK5 may be the underlying genes of inhibiting all trans RA induced neural tube defects.
Keywords:all trans retinoic acid  ASH2L  HDAC4  NSPC1  DOK5  neural tube defects
