Abstract

Objective: To explore the role of Dlx1as, a natural antisense transcript, in mice brain development.

Methods: Based on the bioinformatic and molecular biological findings, we confirmed whether the Dlx1as has a poly-A tail. The temporal expressions of Dlx1as and Dlx1 mRNA were determined by quantitative real-time PCR and the spatial expressions of Dlx1as and Dlx1 mRNA were compared by using in situ hybridization.

Results: Dlx1as had a poly-A signal. Dlx1as's expression was at a high level through a period of time in the embryo development, which was similar with Dlx1 mRNA in temporal but different in spatial.

Conclusions: Dlx1as is highly expressed in a certain period during mice brain development, which spatially supplements the mRNA expression of D1x1. Therefore, it is supposed that Dlx1as influences the mice brain development by regulating Dlx1 mRNA.
