摘要：
This research utilizes pooled CRISPR screens to identify trans-regulators of the Xist gene, crucial for X-chromosome inactivation. The study uncovers previously unknown regulators and their interactions with regulatory elements, providing insights into the complex regulatory landscape governing gene expression during development. The findings highlight the importance of both proximal and distal regulatory elements in controlling Xist levels, with implications for understanding developmental biology and potential applications in biotechnology.
