Next-Generation Sequencing Facilitates Quantitative Analysis of WT, Ring1a-/-, Ring1b-/-, Ring1a/b-/-, Pcgf1/3/5/6-/- and Pcgf1/2/3/4/5/6-/- Embryonic Stem Cells Transcriptomes
Polycomb repressive complexes (PRC) are epigenetic transcriptional repressors by establishing facultative heterochromatin repressive domains and play an essential role in numerous developmental processes. PRC1, which contains the E3 ligases RING1A/B and deposits H2AK119ub, forms six biochemically subcomplexes (PRC1.1-PRC1.6) based on the assembled PCGF protein (PCGF1–PCGF6), and has been involved in the maintenance of embryonic stem (ES) cell state. More recent evidence indicates that PCGF family participates in the self-renewal and pluripotent maintenance. However, it is still enigmatic that how the PCGF family engaged in the controlling process. Here, we generate the Ring1a-/-, Ring1b-/-, Ring1a/b-/-, Pcgf1/3/5/6-/- and Pcgf1/2/3/4/5/6-/- ES cells using CRISPR/Cas9 technique and CRE-LoxP recombination system to discover the central determinants in PCGF family-related biological process. Overall design: Gene expression profiling of WT (control), Ring1a-/-, Ring1b-/-, Ring1a/b-/-, Pcgf1/3/5/6-/- and Pcgf1/2/3/4/5/6-/- embryonic stem cells.
