15 صفحه اولErratic evolution of SRY in higher primates.
SRY, a Y-chromosomal gene that is pivotal in initiating the development of testis and a determinant of male sex in mammals (Goodfellow and Lovell-Badge 1993), has been subject to intense evolutionary study in the past decade (Foster et al. 1992; Tucker and Lundrigan 1993; Whitfield, Lovell-Badge, and Goodfellow 1993; Pamilo and O’Neill 1997; Nagai 2001). SRY protein is a transcription factor co...
متن کاملInteractions between SRY and SOX genes in mammalian sex determination.
The SRY gene on the mammalian Y chromosome undoubtedly acts to determine testis, but it is still quite unclear how. It was originally supposed that SRY acts directly to activate other genes in the testis-determining pathway. This paper presents an alternative hypothesis that SRY functions indirectly, by interacting with related genes SOX3 (from which SRY evolved) and SOX9 (which appears to be i...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Transcription of the sex-determining region genes Sry and Zfy in the mouse preimplantation embryo.
We have confirmed the faster growth of male preimplantation mouse embryos. We have also studied the transcription of Y chromosomal genes postulated to have a role in sex determination, using the highly sensitive technique of reverse-transcription polymerase chain reaction at these early stages. We find that two sex-determining region genes, Sry and Zfy, are transcribed during mouse preimplantat...
