Sox9

The process starts when the transcription factor testis determining factor encoded by the sex-determining region SRY of the Y chromosome activates SOX-9 activity by binding to sox9 enhancer sequence upstream of the gene, sox9. Activation of FGF9 by SOX-9 starts vital processes in male development, sox9, such as the creation of testis cords and the multiplication of Sertoli cells.

The SOX9 protein is especially important for development of the skeleton and plays a key role in the determination of sex before birth. The SOX9 protein attaches binds to specific regions of DNA and regulates the activity of other genes, particularly those that control skeletal development and sex determination.

It acts during chondrocyte differentiation and, with steroidogenic factor 1, regulates transcription of the anti-Muellerian hormone AMH gene.

Zhao B, sox9. Sox9 element increased the activity of a minimal SOX9 promoter in reporter constructs in a dose-dependent manner. The isolated cDNA corresponded to 3.

Alternative titles; symbols. Other entities represented in this entry:. Cytogenetic location: 17q SOX9 is a transcription factor essential for both sex and skeletal development. Transient expression of the Y chromosome gene SRY initiates a cascade of gene interactions orchestrated by SOX9, leading to the formation of testes from bipotential gonads summary by Cox et al. Foster et al. Using this map and a translocation chromosome breakpoint from a sex-reversed patient with campomelic dysplasia see previously reported by Young et al.

The SOX9 protein is especially important for development of the skeleton and plays a key role in the determination of sex before birth. The SOX9 protein attaches binds to specific regions of DNA and regulates the activity of other genes, particularly those that control skeletal development and sex determination. On the basis of this action, the SOX9 protein is called a transcription factor. More than 70 mutations involving the SOX9 gene have been found to cause campomelic dysplasia, a disorder that affects skeletal development, sex determination, and other processes in the body and is often life-threatening in the newborn period.

During development, progenitors simultaneously activate one lineage while silencing another, a feature highly regulated in adult stem cells but derailed in cancers. Equipped to bind cognate motifs in closed chromatin, pioneer factors operate at these crossroads, but how they perform fate switching remains elusive. Here we tackle this question with SOX9, a master regulator that diverts embryonic epidermal stem cells EpdSCs into becoming hair follicle stem cells.

Dimerization and the resulting capacity to activate promoters via dimeric binding sites was lost in both mutant SOX9 proteins while other features involved in SOX9 function remained unaltered. Patel, M. Potential use of Sox9 gene therapy for intervertebral degenerative disc disease. For instance, separate deletions of either Sox9 or Sox10 retain normal formation of oligodendrocytes, whereas the deletion of both results in widespread apoptosis. Kwok, C. Gubbay J. Sox proteins: regulators of cell fate specification and differentiation. Mori-Akiyama Y. Gonen, N. Thompson E. Fantauzzo, K. With 1 exception, all SOX9 nonsense and frameshift mutations in patients with campomelic dysplasia and sex reversal lead to truncation of this domain, suggesting to Sudbeck et al. Two of the patients showed 46,XY sex reversal see

In two 46,XY sisters who exhibited unambiguously female genitalia but did not undergo breast development or menstruation at puberty SRXY10; , Kim et al. After secondary antibody incubation, membranes were then washed four times in 0. Deletion of long-range regulatory elements upstream of SOX9 causes campomelic dysplasia. Dec ; 17 — Meyer et al. The results suggested to the authors that SOX9 plays an essential role in sex determination, possibly immediately downstream of SRY in mammals, and that it functions as a critical Sertoli cell differentiation factor, perhaps in all vertebrates. Qin, Y. The function of Sox9 in HF-SCs was first noted in the HF bulge, an adult-specific stem cell niche that provides an appropriate microenvironment to preserve the proliferative potential of hair follicles. Gene Expr Patterns. Peer review under responsibility of Chongqing Medical University. Trowe, M. Cyclic GMP-dependent protein kinase II inhibits cell proliferation, Sox9 expression and Akt phosphorylation in human glioma cell lines. These data began to provide a clearer picture of how SOX9 functions as a pioneer factor, as it not only binds to closed chromatin but also recruits co-factors to epigenetically modify flanking histones.
