摘要To date, little information has been available regarding genes involved in the regulation of embryonic cell development, which participate in retinoic acid-induced neural tube defects in mice.Previous studies have revealed seven differentially expressed genes involved in neural tube developmental defects. However, gene expression and regulation is a complex process. Therefore,gene expression differences between normal and defective neural tubes at 9.5 and 10.5 days were compared. A total of eight differentially expressed genes exhibited coincident alterations at embryonic 9.5 and 10.5 days. In mice with retinoic acid-induced neural tube defects, NeK7, IGFBP5,ZW10, Csf3r, PSMC6, Cdk5, and Rb1 expressions were downregulated, but Apoa-4 expression was upregulated. These results were confirmed by Northern blot hybridization. Results suggested that NeK7, IGFBP5, ZW10, Csf3r, PSMC6, Cdk5, Rb1, and Apoa-4 are important regulatory factors involved in neural tube defects.
