Meiosis is a process unique to the differentiation of germ cells. Retinoic acid (RA) is the key factor controlling the sex-specific timing of meiotic initiation in tetrapods; however, the role of RA in meiotic initiation in teleosts has remained unclear. In this study, the genes encoding RA synthase aldh1a2, and catabolic enzyme cyp26a1 were isolated from(More)
The fox genes play important roles in various biological processes, including sexual development. In the present study, we isolated 65 fox genes, belonging to 18 subfamilies named A-R, from Nile tilapia through genome-wide screening. Twenty-four of them have two or three (foxm1) copies. Furthermore, 16, 25, 68, and 45 fox members were isolated from(More)
MicroRNAs (miRNAs) represent a second regulatory network that has important effects on gene expression and protein translation during biological process. However, the possible role of miRNAs in the early stages of fish sex differentiation is not well understood. In this study, we carried an integrated analysis of miRNA and mRNA expression profiles to(More)
The complete mitochondrial genome was sequenced from one of the endemic bitterling fish in China. The mitochondrial genome sequence was 16,575 bp in size, and the gene order and contents were identical with the species of the same subfamily like T. lanceolata, T. limbata, Acheilognathus macropterus and A. yamatsutae. Five genes (COII, COIII, ND3, ND6, and(More)
The dmrt6 gene has been isolated from tetrapods and recently from a coelacanth, Latimeria chalumnae. Its evolutionary history and exact function remain unclear. In the present study, dmrt6 was isolated from Perciformes (five cichlids and stickleback), Siluriformes (southern catfish), and Lepisosteiformes (spotted gar).
