Abstract
For the digestion of food, it is important for the gut to be differentiated regionally and to have proper motor control. However, the number of transcription factors that regulate its development is still limited. Meanwhile, the interstitial cells of the gastrointestinal (GI) tract are necessary for intestinal motility in addition to the enteric nervous system. There are Anoctamine1 (Ano1)-positive and Platelet-derived growth factor receptor alpha (Pdgfra)-positive interstitial cells in mammal, but Pdgfra-positive cells have not been reported in the zebrafish. To identify new transcription factors involved in GI tract development, we used RNA-sequencing comparing between larval and adult gut. We isolated 40 transcription factors that were more highly expressed in the larval gut. We demonstrated expression patterns of the 13 genes, 7 of which were newly found to be expressed in the zebrafish larval gut. Six of the 13 genes encode nuclear receptors. The osr2 is expressed in the anterior part, while foxP4, in its distal part. Also, we reported the expression pattern of pdgfra for the first time in the larval zebrafish gut. Our data would provide fundamental knowledge for studying vertebrate gut regionalization and motility by live-imaging using zebrafish. This article is protected by copyright. All rights reserved.
