Summary: Co-dependency mapping assays have identified genetic dependencies in cancer and can provide insights into chromatin crosstalk mechanisms. The authors developed a pipeline to integrate co-dependency mapping with molecular information in pan-cancer cell lines to uncover chromatin complexes and potential drug targets. This study sheds light on trans-regulatory interactions as mechanisms of chromatin regulation and potential synthetic lethality targets.

Summary: Infertility affects 15% of couples worldwide, with recurrent implantation failure (RIF) being a major issue in IVF-ET programs. This study revealed that a uterine gene network regulated by the polycomb repressive complex 2 (PRC2) controls embryo implantation. Dysregulation of PRC2 components and target genes was observed in patients with RIF. Knockout mice studies showed that stromal Ezh2 plays a crucial role in female fertility. This research highlighted the importance of the EZH2-PRC2-H3K27me3 axis in preparing the endometrium for successful embryo invasion.

Summary: In colorectal cancer (CRC), active AKT phosphorylates EZH2 on serine 21, leading to the modulation of gene expression through the AKT/EZH2/beta-catenin axis. EZH2 interacts with and methylates beta-catenin, increasing its binding to chromatin and promoting transcription. Furthermore, EZH2-mediated beta-catenin trimethylation enhances its interaction with TCF1 and RNA polymerase II, resulting in significant gains in genomic regions with beta-catenin occupancy.

Summary: This study investigates the pharmacological mechanism of the PRC2 inhibitor MAK683 and identifies a group of senescence-associated genes that are derepressed upon PRC2 inhibition, leading to tumor regression and improved therapeutic efficacy. Furthermore, the combination of PRC2 inhibitors and CDK4/6 inhibitors shows even better effects, providing a novel strategy for clinical treatment.

Summary: The hippocampus plays a crucial role in learning and memory, and its development requires precise coordination of cell patterning, proliferation, differentiation, and migration. In this study, it was found that KDM2B mediates a gene repressive program that controls fate specification and cell migration in the hippocampus, affecting its morphology and related behaviors.

Summary: The authors identify SUZ12 as a cellular substate of casein kinase 2 (CK2) and highlight its role in promoting PRC2 function in cell identity maintenance during stem cell differentiation. This phosphorylation-dependent mechanism stimulates PRC2 enzymatic activity, enhancing its binding to substrates and promoting gene repression. Loss of this phosphorylation impairs PRC2 recruitment and compromises its ability to maintain differentiated cell identity.

Summary: PALI1 is a newly identified accessory protein that plays a role in advanced prostate cancer. It competes with JARID2 for binding to the PRC2 core subunit SUZ12 and interacts with the H3K9 methyltransferase G9A, forming a unique super-complex involved in dual H3K9/K27 methylation and gene repression. PALI1 and G9A promote prostate cancer cell proliferation and invasion, and drive tumor growth in xenograft models.

Summary: CTR9 is a scaffold subunit in PAFc complex and plays a crucial role in controlling H3K27me3 levels and genomic distribution mediated by PRC2. Loss of CTR9 leads to increased H3K27me3 levels, expanded recruitment of PRC2 on chromatin, and a shift from less active PRC2.2 to more active PRC2.1, resulting in hypersensitivity of breast cancer cells to PRC2 inhibitors.

Summary: The study found that U2AF1 mutations are associated with poor prognosis in MDS and AML patients, significantly inhibiting cell proliferation and inducing cellular apoptosis in cell models. The results showed that U2AF1 mutations promoted FOXO3a-dependent apoptosis and NLRP3 inflammasome activation, leading to pyroptotic cell death. FOXO3a was identified as the key molecule on which these pathways converge.

Summary: Link prediction is a classical problem in the field of complex networks, which is of great significance for understanding the evolution and dynamic development mechanisms of networks. This study proposes a novel method called MOLI, which utilizes local information from neighbors at different distances and defines a local network diffusion process via random walks on the graph, achieving better utilization of network information. The results show that MOLI outperforms other widely used link prediction methods on different types of networks.

Summary: Network models are widely used in various fields for their ability to represent relationships between variables. Network structure can be unclear due to factors like experimental noise and missing data, hindering downstream analyses such as community detection. Therefore, network denoising is necessary before analysis. However, the importance of network pre-processing for community detection has been neglected. In this study, a novel network denoising method, called Network Refinement (NR), was proposed to enhance the self-organization properties of complex networks through a global diffusion process. NR significantly improved the clarity of the network's mesoscale structure and boosted the performance of various community detection algorithms.
