Project description:Epithelioid hemangioendothelioma (EHE) is a rare vascular sarcoma that is associated with a TAZ-CAMTA1 fusion in greater than 90% of cases and loss of CDKN2A in human EHE tumors is associated with late stage disease. Murine EHE tumors were created by conditionally expressing TAZ-CAMTA1 and conditionally knocking out Cdkn2a within vascular endothelium. Resultant tumors were used for single cell RNA sequencing and compared against age matched wild type mice tissue.
Project description:Epithelioid hemangioendothelioma (EHE) is a rare vascular sarcoma that is associated with a WWTR1-CAMTA1 fusion gene in greater than 90% of cases. Cell lines were generated from WWTR1-CAMTA1 positive murine EHE tumors which also harbor a loss of CDKN2A. RNA sequencing was performed on cell lines.
Project description:Epithelioid hemangioendothelioma (EHE) is a rare vascular sarcoma that is associated with a WWTR1-CAMTA1 fusion gene in greater than 90% of cases. Using an adaptation of the FLEx system, we generated a genetically engineered mouse model of EHE whereby the endogenous Wwtr1 Locus is replaced with an Wwtr1-Camta1 locus. Tumors generated from this mouse model were dissociated and a 10X genomics library preparation was performed. The barcoded library was then deep sequenced.
Project description:Epithelioid hemangioendothelioma (EHE) is a rare vascular sarcoma that is associated with a WWTR1-CAMTA1 fusion gene in greater than 90% of cases. We aimed to investigate the transcriptional pathways activated in EHE. Total RNA was isolated from EHE tumors from surgical resection or autopsy specimens (n=6) followed by RNA-Seq. The results of this study identified a unique transcriptional profile for EHE and helped to validate a novel murine model of EHE.

Using an adaptation of the FLEx system, we generated a genetically engineered mouse model of EHE whereby the endogenous Wwtr1 Locus is replaced with an Wwtr1-Camta1 locus. RNA was isolated from the resultant tumors and from control liver tissue and RNA sequencing was performed. Cross species analysis between human and mice tumors demonstrated murine EHE maintains the defining transcriptional features of human EHE.
