Abstract
Mesenchymal stromal cells (MSCs) contribute to the microenvironment regulating normal and malignant hematopoiesis, and thus may support subpopulations of cancer cells to escape therapeutic pressure. Here, we engineered bone marrow MSCs to express a synthetic CD19-sensor receptor to detect and display interacting primary CD19+ leukemia cells in coculture. This implementation provides a versatile platform facilitating ex vivo drug response profiling of primary CD19+ leukemia cells in coculture with high-sensitivity and scalability.

Vanoli F, Antonescu CR. Modeling sarcoma relevant translocations using CRISPR-Cas9 in human embryonic stem derived mesenchymal precursors. Genes Chromosomes Cancer 2023; 62:501-509. [PMID: 36965130 PMCID: PMC10725040 DOI: 10.1002/gcc.23141] [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: 01/24/2023] [Revised: 03/06/2023] [Accepted: 03/16/2023] [Indexed: 03/27/2023] Open
Abstract
The role of cancer relevant translocations in tumorigenesis has been historically hampered by the lack of faithful in vitro and in vivo models. The development of the latest genome editing tools (e.g., CRISPR-Cas9) allowed modeling of various chromosomal translocations with different effects on proliferation and transformation capacity depending on the cell line used and secondary genetic alterations. The cellular context is particularly relevant in the case of oncogenic fusions expressed in sarcomas whose histogenesis remain uncertain. Moreover, recent studies have emphasized the increased frequency of gene fusion promiscuity across different mesenchymal tumor entities, which are clinicopathologically unrelated. This review provides a summary of different strategies utilized to generate cancer models with a focus on fusion-driven mesenchymal neoplasia.

BAF complexes drive proliferation and block myogenic differentiation in fusion-positive rhabdomyosarcoma. Nat Commun 2021; 12:6924. [PMID: 34836971 PMCID: PMC8626462 DOI: 10.1038/s41467-021-27176-w] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Accepted: 10/25/2021] [Indexed: 12/12/2022] Open
Abstract
Rhabdomyosarcoma (RMS) is a pediatric malignancy of skeletal muscle lineage. The aggressive alveolar subtype is characterized by t(2;13) or t(1;13) translocations encoding for PAX3- or PAX7-FOXO1 chimeric transcription factors, respectively, and are referred to as fusion positive RMS (FP-RMS). The fusion gene alters the myogenic program and maintains the proliferative state while blocking terminal differentiation. Here, we investigated the contributions of chromatin regulatory complexes to FP-RMS tumor maintenance. We define the mSWI/SNF functional repertoire in FP-RMS. We find that SMARCA4 (encoding BRG1) is overexpressed in this malignancy compared to skeletal muscle and is essential for cell proliferation. Proteomic studies suggest proximity between PAX3-FOXO1 and BAF complexes, which is further supported by genome-wide binding profiles revealing enhancer colocalization of BAF with core regulatory transcription factors. Further, mSWI/SNF complexes localize to sites of de novo histone acetylation. Phenotypically, interference with mSWI/SNF complex function induces transcriptional activation of the skeletal muscle differentiation program associated with MYCN enhancer invasion at myogenic target genes, which is recapitulated by BRG1 targeting compounds. We conclude that inhibition of BRG1 overcomes the differentiation blockade of FP-RMS cells and may provide a therapeutic strategy for this lethal childhood tumor.
