Glycolysis, the classic pathway for producing energy, has been known to be involved in neural development. Notch signaling also contributes to neural development and regulation of glycolysis in various tissues. However, the role of Notch signaling in glycolysis-related gene regulation during neural development is poorly understood. Here, we analyzed mRNA expression patterns and levels of glucose transporters (GLUT) as well as rate-limiting enzymes in glycolysis using zebrafish mib1ta52b mutants, in which Notch signaling was deficient at the early embryonic and larval stages. Our results indicated that in neural tissues, Notch signaling positively regulates glut1a and glut3a expression and negatively regulates hk2 expression at the larval stage but may not regulate them during early embryonic stages. Therefore, these results suggest that Notch signaling regulates glycolysis-related gene expression in a context-dependent manner in neural tissues at different developmental stages.
