Sox15 is up regulated in the embryonic mouse testis

Abstract

The mammalian sex determining region on the Y chromosome, SRY, is the founding member of the SOX gene family. SOX genes share a common DNA-binding motif termed the HMG box and have diverse roles in vertebrate embryonic development and tissue differentiation. Sox15 expression was analysed during mouse embryogenesis by whole-mount in situ hybridisation and Real Time RT-PCR. Sox15 was found to be expressed in developing mouse gonads from 11.5 dpc to 13.5 dpc with a peak of expression at 12.5 dpc. Expression was approximately twice as high in the male gonad as in the female gonad. © 2003 Elsevier B.V. All rights reserved.
