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. Most cases of campomelic dysplasia are caused by mutations within the SOX9 gene. These mutations prevent the production of the SOX9 protein or result in a protein with impaired ability to function as a transcription factor. About 5 percent of cases are caused by chromosome abnormalities that occur near the SOX9 gene. These chromosome abnormalities disrupt regions of DNA called enhancers that normally regulate the activity of the SOX9 gene. All of these genetic changes prevent the SOX9 protein from properly controlling the genes essential for normal development of the skeleton, reproductive organs, and other parts of the body. Abnormal development of these structures causes the signs and symptoms of campomelic dysplasia. Individuals with milder forms of campomelic dysplasia are more likely to have chromosome abnormalities near the SOX9 gene rather than mutations within the gene.

The genital abnormalities consisted of bifid scrotum, perineal hypospadias, and undescended right testis. Haydon: ude. Sox9 Genetics.

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.

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. Combining epigenetic, proteomic and functional analyses, we interrogate the ensuing chromatin and transcriptional dynamics, slowed temporally by the mature EpdSC niche microenvironment. We show that as SOX9 binds and opens key hair follicle enhancers de novo in EpdSCs, it simultaneously recruits co-factors away from epidermal enhancers, which are silenced.

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 an enhancer sequence upstream of the gene. Activation of FGF9 by SOX-9 starts vital processes in male development, such as the creation of testis cords and the multiplication of Sertoli cells. SOX-9 is a target of the Notch signaling pathway , as well as the Hedgehog pathway , [13] and plays a role in the regulation of neural stem cell fate. In vivo and in vitro studies show that SOX-9 negatively regulates neurogenesis and positively regulates gliogenesis and stem cell survival. Mutations lead to the skeletal malformation syndrome campomelic dysplasia , frequently with autosomal sex-reversal [6] and cleft palate. SOX9 sits in a gene desert on 17q24 in humans. The Sox9 protein has been implicated in both initiation and progression of multiple solid tumors.

Consequently, they speculated that the gene may play a critical role in differentiation or sex determination as a functional RNA. Malki S. These results demonstrated that COL2A1 expression is directly regulated by SOX9 protein in vivo and implicated abnormal regulation of COL2A1 during chondrogenesis as a cause of the skeletal abnormalities associated with campomelic dysplasia.
