神经发生是一个复杂的过程,依赖于空间和时间基因表达的微妙调控。在我们之前的研究中,我们发现转录的超保守区(T-UCRs),一类含有UCRs的长非编码RNA,在小鼠,恒河猴和人类的发育神经系统中表达。在本研究中,我们首先检测了T-uc. 189的全长序列,揭示了它主要集中在脑室区(VZ),并且随着大脑的成熟,它的表达减少。此外,我们证明,敲低T-uc. 189抑制神经发生。此外,我们发现T-uc. 189正调控富含丝氨酸精氨酸的剪接因子3(Srsf3)的表达。综上所述,我们的研究结果是第一次证明,T-uc. 189调节Srsf3的表达,以维持正常的神经发生在皮层发育。
Neurogenesis is a complex process that depends on the delicate regulation of spatial and temporal gene expression. In our previous study, we found that transcribed ultra-conserved regions (T-UCRs), a class of long non-coding RNAs that contain UCRs, are expressed in the developing nervous systems of mice, rhesus monkeys, and humans. In this study, we first detected the full-length sequence of T-uc.189, revealing that it was mainly concentrated in the ventricular zone (VZ) and that its expression decreased as the brain matured. Moreover, we demonstrated that knockdown of T-uc.189 inhibited neurogenesis. In addition, we found that T-uc.189 positively regulated the expression of serine-arginine-rich splicing factor 3 (Srsf3). Taken together, our results are the first to demonstrate that T-uc.189 regulates the expression of Srsf3 to maintain normal neurogenesis during cortical development.
