在非活动 X 染色体上重新激活 MeCP2 的池 shRNA 屏幕

Overview

This article presents a protocol utilizing small hairpin RNA (shRNA) and next generation sequencing to identify regulators of X-chromosome inactivation in a murine cell line. The study incorporates firefly luciferase and hygromycin resistance genes fused to the methyl CpG binding protein 2 (MeCP2) gene on the inactive X chromosome.
