Discrete subsets of myogenic and mesenchymal precursors give rise to soft tissue sarcomas of distinct lineage differentiation

ABSTRACT: This work examines sarcoma formation within discrete subsets of KRAS(G12V)-expressing p16p19null myogenic and mesenchymal cells found normally in skeletal muscle. We show that prospectively isolated skeletal muscle precursor cells (SMPs) within the satellite cell pool can serve as cancer cells-of-origin for mouse rhabdomyosarcomas (soft tissue sarcomas with features of myogenic differentiation). Alternatively, non-myogenic progenitors (ScaPCs) induce sarcomas lacking myogenic differentiation markers.

Discrete subsets of myogenic and mesenchymal precursors give rise to soft tissue sarcomas of distinct lineage differentiation

Project description:This work examines sarcoma formation within discrete subsets of KRAS(G12V)-expressing p16p19null myogenic and mesenchymal cells found normally in skeletal muscle. We show that prospectively isolated skeletal muscle precursor cells (SMPs) within the satellite cell pool can serve as cancer cells-of-origin for mouse rhabdomyosarcomas (soft tissue sarcomas with features of myogenic differentiation). Alternatively, non-myogenic progenitors (ScaPCs) induce sarcomas lacking myogenic differentiation markers. We used Affymetrix whole mouse genome 430 2.0 microarrays to gain deeper insights into the molecular underpinnings of the three types of KRAS; p16p19null mouse soft-tissue sarcomas (originating from SMPs, ScaPCs and CD45-MAC1-TER119-Sca1-CXCR4- cells). Four replicates of each type.

20 human soft-tissue sarcomas (TMT)

Project description:SCX fractiond, TMT labeled pleomorphic soft-tissue sarcomas. 32 raw files (8x4) plus 8 pools (also TMT labeled) corresponding to each SCX fraction are submitted. The latter were used to propagate identifications across the runs.

Spatial transcriptomics analysis of soft tissue sarcomas.

Project description:The tumor microenvironment plays a crucial role in soft tissue sarcoma development and response to therapy. We used spatial transcriptomics to analyze the spatial distribution of malignant, immune, and other stromal cells present within soft tissue sarcomas.

Nitrocamptothecin in Treating Patients With Soft Tissue Sarcomas

Project description:RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of nitrocamptothecin in treating patients who have locally advanced or metastatic soft tissue sarcomas.

EWS/ATF1 activates Fos and induces soft tissue sarcomas [Affymetrix].

Project description:Clear cell sarcoma (CCS) is an aggressive soft tissue malignant tumor characterized by a unique t(12; 22) translocation, leading to the expression of a chimeric EWS/ATF1 fusion gene. However, little is known about the mechanisms underlying how EWS/ATF1 is involved in the development of CCSs. In addition, the cells of origin for CCSs remain to be determined. We generated EWS/ATF1-inducible mice, and examined the effects of EWS/ATF1 expression in adult cells. We show that the forced expression of EWS/ATF1 results in the development of EWS/ATF1-dependent sarcomas in mice. The histology of EWS/ATF1-induced sarcomas resembles that of CCSs and EWS/ATF1-induced tumor cells express CCS-markers, such as S100, Sox10, and Mitf. A lineage tracing experiment revealed that such sarcomas are derived from neural crest-lineage cells. Finally, we found that EWS/ATF1 directly induces Fos in an ERK-independent manner, and demonstrated that the increased Fos expression is important for the active cell proliferation in not only EWS/ATF1-induced sarcomas, but also in human CCSs. Our results indicate that FOS, as well as EWS/ATF1 itself, could be a promising therapeutic target for the treatment of EWS/ATF1-related sarcomas.

Distinct expression profiles of soft tissue sarcomas

Project description:Soft tissue sarcomas (STTs) are neoplasms of mesenchymal cells, and are composed of more than 60 subtypes. Although many of these STTs could be distinguished from each other by morphology and limited IHC biomarkers, the precise diagnosis of STTs with similar morphology is still difficult to achieve. Therefore developing novel diagnosis biomarker and molecular signatures will be very helpful to pathologist in clinic.
