Project description:185-3 MPNST cells cells were screened with a CRISPR library against TSGs in vitro and as tumors in Rag1-null and immunocompetent WT C57BL/6 mice
Project description:B16 melanoma cells were screened with a CRISPR library against TSGs in vitro and as tumors in Rag1-null and immunocompetent WT C57BL/6 mice
Project description:KP1233 lung tumor cells cells were screened with a CRISPR library against TSGs in vitro and as tumors in Rag1-null and immunocompetent WT C57BL/6 mice
Project description:Cancers are characterized by non-random, chromosome copy number variations that presumably contain oncogenes and tumor suppressor genes (TSGs). The affected loci are often large, making it difficult to pinpoint which genes are driving the cancer. Here, we report a cross-species, in vivo screen of 84 candidate oncogenes and 39 candidate TSGs, located within 28 recurrent chromosomal alterations in ependymoma. Through a series of mouse models we validate eight new ependymoma oncogenes and 11 TSGs that dysregulate a small number of cell functions including vesicle trafficking and cholesterol biosynthesis; pinpointing these as potential points for therapeutic intervention. Mouse cortical tumors were excised. These tumors derived from cells expressing one of 3 genes: RAB3A, BC74C, or ZNF668
Project description:C57BL/6 mouse pancreas cells were infected with a CRISPR library targeting TSGs. Total HLA and SIINFEKL presentation was measured by flow and cells were sorted for sequencing

Project description:Malignant peripheral nerve sheath tumor (MPNST) is a rare sarcoma that lacks effective therapeutic strategies. By characterizing recurrent gene copy number aberrations, we gain insight into the most altered pathways with the purpose of scanning possible therapeutic targets. We conducted a microarray-based comparative genomic hybridization profiling of two cohorts of primary MPNST tissue samples including 25 patients treated at The University of Texas MD Anderson Cancer Center and 26 patients from Tianjin Cancer Hospital. All samples had at least 90% tumor content. Commercially available normal genomic DNAs were used as control.
