Abstract:

As a master transcription factor regulating cartilage, craniofacial and gonad development, the expression level of SOX9 is strictly regulated in different tissues. Previous studies have well revealed that structural variations of non-coding regions around SOX9 are associated with cartilaginous abnormalities, craniofacial malformations and sex reversal, indicating different areas upstream of SOX9 could harbor various tissue-specific enhancers. Cartilage-specific enhancers of SOX9 include E84, E195, E250 and RCSE, whereas the E3 enhancer and F2 enhancer may activate SOX9 expression in craniofacial development, and Enh13 as well as TES are gonad specific enhancers of SOX9. More candidate tissue-specific enhancers of SOX9 could be identified through chromosome conformation capture techniques, chromatin accessibility analysis and species conservation analysis. In addition, functional study of these enhancers could shed light on the mechanism of regulating SOX9 gene expression and disease development.

摘要:

SOX9(SRY-related high-mobility-group-box gene 9)作为在软骨、颅颌面及性腺发育中的重要基因,在不同组织中的表达受到精细的调控。既往研究揭示了SOX9非编码区域的染色体结构异常同软骨发育障碍、颅颌面畸形、性别反转等表型相关,且SOX9基因上游不同区段内包含组织特异性调控其表达的增强子元件,如E84、E195、E250、RCSE等与SOX9在软骨组织的表达相关。E3、F2等增强子负责调控SOX9在颅颌面组织中的表达,而Enh13、TES等则为SOX9的性腺特异性增强子。通过染色质构象捕获、染色质开放性分析、种属间保守性分析等方法,可发掘更多调控SOX9在不同组织中表达的增强子。结合功能研究,有望进一步深入阐明组织特异性增强子在调控SOX9基因表达和疾病发生中的作用机制。
