service@sailgene.comIntroduction
ATAC-seq (Assay for Transposase Accessible Chromatin with High-Throughput Sequencing) is a high-throughput sequencing technology used to study chromatin accessibility. This method leverages the Tn5 transposase, which recognizes and binds to open chromatin regions. It simultaneously cuts the DNA at these regions and inserts sequencing adapters at both ends of the cut DNA fragments. High-throughput sequencing is then performed to identify open chromatin regions across the genome. This technique is commonly used to investigate how chromatin structure influences gene transcriptional regulation.

Abstract：Gonadal sex determination relies on tipping a delicate balance involving the activation and repression of several transcription factors and signaling pathways. This is likely mediated by numerous noncoding regulatory elements that shape sex-specific transcriptomic programs. To explore the dynamics of these in detail, we performed paired time series of transcriptomic and chromatin accessibility assays on pre-granulosa and Sertoli cells throughout their development in the embryo, making use of new and existing mouse reporter lines. Regulatory elements were associated with their putative target genes by linkage analysis, and this was complemented and verified experimentally using promoter capture Hi-C. We identified the transcription factor motifs enriched in these regulatory elements along with their occupancy, pinpointing LHX9/EMX2 as potentially critical regulators of ovarian development. Variations in the DNA sequence of these regulatory elements are likely to be responsible for many of the unexplained cases of individuals with differences of sex development.
