生殖道系统的性二态性建立需要中肾的Wolffian管和Müllerian管的性别特异性退化。在XX胚胎中,沃尔夫管在间充质转录因子COUP-TFII的控制下退化。为了了解Wolffian管退化的细胞和分子作用,我们对XX中肾(有或没有Coup-TFII)进行了转录组学分析,并对XX中肾中的COUP-TFII染色质占有率进行了全基因组分析。COUP-TFII全基因组结合和转录组学分析的综合分析揭示了COUP-TFII对肌肉分化和细胞外基质基因的抑制,并确定了一组COUP-TFII在间充质中的潜在转录伙伴,这些转录伙伴可能促进沃尔夫管消退。这些研究结果提供了深入了解的分子作用的COUP-TFII在沃尔夫管间充质,并确定了一系列的生物学相关的候选基因和途径,为未来的功能分析在生殖道的性别分化。
Sexually dimorphic establishment of the reproductive tract system requires sex-specific regression of the Wolffian duct and Müllerian duct in the mesonephros. In an XX embryo, the Wolffian duct regresses under the control of the mesenchymal transcription factor COUP-TFII. To understand cellular and molecular actions underlying Wolffian duct regression, we performed transcriptomic analyses of XX mesonephroi with or without Coup-tfII and genome-wide analysis of COUP-TFII chromatin occupancy in XX mesonephroi. The integrative analysis of COUP-TFII genome-wide binding and transcriptomic analysis revealed the suppression of muscle differentiation and extracellular matrix genes by COUP-TFII and identified a group of COUP-TFII’s potential transcriptional partners in the mesenchyme that potentially facilitate Wolffian duct regression. These findings provide insights into the molecular action of COUP-TFII in the Wolffian duct mesenchyme and identify a list of biologically relevant candidate genes and pathways for future functional analyses in sexual differentiation of reproductive tracts.
