| 内容記述 | The nanos gene is essential for germ cell development. Although its functions and expression have been investigated in mouse, nanos genes in other vertebrates are yet to be well characterized. Based on the similarity and syntenic analysis of nanos, we have identified four different nanos on the genome of medaka (Oryzias latipes). Nanos1 is duplicated on teleost fish genomes and named as nanos1a and nanos1b. Of all medaka nanos, nanos3 is well conserved in terms of expression and synteny. In contrast to a previous study on mice, nanos2 was not detected in the gonads at early stages of sex differentiation; however, both oogonia and spermatogonia in adult gonads exhibit nanos2 expression. Nanos1a and 1b are both expressed in the developing brains, consistent with the expression of mice nanos1. In the gonads, nanos1a is expressed in the somatic cells surrounding oocytes and spermatocytes, whereas expression of nanos1b is not detectable in the gonads by in situ hybridization. These results suggest common and distinct functions of nanos genes among vertebrates. | |||||
