Project description:Meningeal solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms that are associated with hematogenous metastasis, and the cell states and spatial transcriptomic architecture of SFTs are unknown. Here we use single-cell and spatial RNA sequencing to show SFTs are comprised of regionally distinct gene expression programs that resemble cerebral vascular development and homeostasis. Our results shed light on mechanisms underlying SFT biology in comparison to other central nervous system tumors and provide a framework for integrating single-cell and spatial transcriptomic data in human cancer samples.
Project description:Gene expression profiling of human solitary fibrous tumor samples was performed using the NanoString Human nCounter PanCancer IO 360 Panel
Project description:In this study, we characterize the fusion protein produced by the EPC1-PHF1 translocation in Low Grade Endometrial Stromal Sarcoma (LG-ESS) and Ossifying FibroMyxoid Tumors (OFMT). We express the fusion protein and necessary controls in K562 Cells. The fusion protein assembles a mega-complex harboring both NuA4/TIP60 and PRC2 subunits and enzymatic activities and leads to mislocalization of chromatin marks in the genome, linked to aberrant gene expression.
