Prion-like domain mediated phase separation of ARID1A promotes oncogenic potential of Ewing's sarcoma. Nat Commun 2024; 15:6569. [PMID: 39095374 PMCID: PMC11297139 DOI: 10.1038/s41467-024-51050-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Accepted: 07/26/2024] [Indexed: 08/04/2024] Open
Abstract
Liquid-liquid phase separation (LLPS) facilitates the formation of membraneless organelles within cells, with implications in various biological processes and disease states. AT-rich interactive domain-containing protein 1A (ARID1A) is a chromatin remodeling factor frequently associated with cancer mutations, yet its functional mechanism remains largely unknown. Here, we find that ARID1A harbors a prion-like domain (PrLD), which facilitates the formation of liquid condensates through PrLD-mediated LLPS. The nuclear condensates formed by ARID1A LLPS are significantly elevated in Ewing's sarcoma patient specimen. Disruption of ARID1A LLPS results in diminished proliferative and invasive abilities in Ewing's sarcoma cells. Through genome-wide chromatin structure and transcription profiling, we identify that the ARID1A condensate localizes to EWS/FLI1 target enhancers and induces long-range chromatin architectural changes by forming functional chromatin remodeling hubs at oncogenic target genes. Collectively, our findings demonstrate that ARID1A promotes oncogenic potential through PrLD-mediated LLPS, offering a potential therapeutic approach for treating Ewing's sarcoma.

Abstract
We have established Noonan syndrome (NS)-derived induced pluripotent stem cell (iPSC) lines derived from peripheral blood mononuclear cells (PBMCs) of a family cohort carrying the heterozygous PTPN11 c.188 A > G (p.Y63C) mutation. The new iPSC lines were validated by confirming the normal karyotype and targeted mutation, the pluripotent gene expression, and the differentiation capacity into three germ layers.

Abstract
The zebrafish is an ideal model for functional analysis of genes at the molecular, protein, cell, organ, and organism levels. We have used zebrafish to analyze the function of members of the protein tyrosine phosphatase (PTP) superfamily for more than two decades. The molecular genetic toolbox has significantly improved over the years. Currently, generating mutant lines that lack the function of a PTP gene is relatively straightforward by CRISPR/Cas9 technology-mediated generation of insertions or deletions in the target gene. In addition, generating point mutations using CRISPR/Cas9 technology and homology-directed repair (HDR) is feasible, albeit the success rate could be higher. Here, we describe the methods, including the tips and tricks, that we have used to generate knock-out and knock-in zebrafish lines in PTP genes successfully.

Lyulcheva-Bennett E, Genomics England Research Consortium, Bennett D. A retrospective analysis of phosphatase catalytic subunit gene variants in patients with rare disorders identifies novel candidate neurodevelopmental disease genes. Front Cell Dev Biol 2023; 11:1107930. [PMID: 37056996 PMCID: PMC10086149 DOI: 10.3389/fcell.2023.1107930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Accepted: 03/03/2023] [Indexed: 03/30/2023] Open
Abstract
Rare genetic disorders represent some of the most severe and life-limiting conditions that constitute a considerable burden on global healthcare systems and societies. Most individuals affected by rare disorders remain undiagnosed, highlighting the unmet need for improved disease gene discovery and novel variant interpretation. Aberrant (de) phosphorylation can have profound pathological consequences underpinning many disease processes. Numerous phosphatases and associated proteins have been identified as disease genes, with many more likely to have gone undiscovered thus far. To begin to address these issues, we have performed a systematic survey of de novo variants amongst 189 genes encoding phosphatase catalytic subunits found in rare disease patients recruited to the 100,000 Genomes Project (100 kGP), the largest national sequencing project of its kind in the United Kingdom. We found that 49% of phosphatases were found to carry de novo mutation(s) in this cohort. Only 25% of these phosphatases have been previously linked to genetic disorders. A gene-to-patient approach matching variants to phenotypic data identified 9 novel candidate rare-disease genes: PTPRD, PTPRG, PTPRT, PTPRU, PTPRZ1, MTMR3, GAK, TPTE2, PTPN18. As the number of patients undergoing whole genome sequencing increases and information sharing improves, we anticipate that reiterative analysis of genomic and phenotypic data will continue to identify candidate phosphatase disease genes for functional validation. This is the first step towards delineating the aetiology of rare genetic disorders associated with altered phosphatase function, leading to new biological insights and improved clinical outcomes for the affected individuals and their families.
