Involvement of homeobox genes in mammalian sexual development.

چکیده
In eutherian mammals, sexual development hinges on the differentiation of the gonadal primordia into either testes or ovaries, in turn determined by the activity of the Y-linked gene Sry. Organogenesis of the gonads requires input from a complex network of morphogenetic signals, many of which are still uncharacterised. Homeobox genes are known to play important roles in embryo morphogenesis and organogenesis in a number of systems. Here, we review current data relating to possible roles of the extended homeobox gene family on gonad development, sex-specific morphogenesis and gametogenesis, and speculate that these genes may play a broader role in these processes than is currently suspected.

The homeobox genes are known to play a crucial role in controlling the development of multicellular organisms. The majority of these genes have been determined to express regulatory proteins act as a regulatory protein. These trans-acting factors regulate the expression of proteins that are necessary during the developmental processes throughout the body. TGIFLX/Y is a homeobox gene and it cont...
متن کاملP-65: Maternal Effect Genes in Mammalian Reproduction
Background: Regulation of gene expression in mammalian embryos is not completely known. Pre-implantation embryos need maternal RNA and proteins synthesized during oogenesis, to regulate development before mater-embryo transition, as the grown oocyte and the 1-cell zygote are transcriptionally silent. There are some oocyte-specific genes called maternal effect genes which may account for this ea...

Thyroid transcription factor 1 (TTF1) [also known as Nkx2.1 (related to the NK-2 class of homeobox genes) and T/ebp (thyroid-specific enhancer-binding protein)], a homeodomain gene required for basal forebrain morphogenesis, remains expressed in the hypothalamus after birth, suggesting a role in neuroendocrine function. Here, we show an involvement of TTF1 in the control of mammalian puberty an...
متن کاملExpression and Purification of Homeodomain
Homeobox genes encode transcription factors which play important roles in the developmental processes of many multicellular organisms. TGIFLX/Y (TGIFLX and TGIFLY) are members of the homeobox superfamily of genes. Their expressions are specifically detected in the human adult testis but their functions are remained to be investigated. In this investigation we cloned full length of TGIFLY cDNA a...
متن کاملThe Dlx5 and Dlx6 homeobox genes are essential for craniofacial, axial, and appendicular skeletal development.
Dlx homeobox genes are mammalian homologs of the Drosophila Distal-less (Dll) gene. The Dlx/Dll gene family is of ancient origin and appears to play a role in appendage development in essentially all species in which it has been identified. In Drosophila, Dll is expressed in the distal portion of the developing appendages and is critical for the development of distal structures. In addition, hu...
