Project description:We utilized murine osteosarcoma cell lines F420 and K7M2. F420 was originally derived from a female C57BL/6 mouse transgenic for a mutant p53 under control of a bone-selective promoter (PMID: 25579177). K7M2 was derived from a spontaneous metastatic lesion in a female Balb/C background (PMID: 16837208). F420 osteosarcoma tumors were established by subcutaneously injecting 5 x 10^6 osteosarcoma cells into the flanks of 6-week-old C57BL/6 mice (Envigo, Frederick, MD). K7M2 tumors were established by transplanting small pieces of sectioned tumor (~2mm3) into the flanks of 6-week-old Balb/C mice (Envigo). We found K7M2 to be more immunogenic than F420 as it demonstrated higher immune cell infiltrates, higher expression of immune-related genes, and slower growth in syngeneic versus nude models.
Project description:To identify OS-specific gene alterations, 38 tumor samples were collected from 29 unique patients with osteosarcoma. We performed RNA-sequencing on 28 primary osteosarcoma tumors and 10 metastatic osteosarcoma tumors. We compared the primary and metastatic genomic signatures of all 38 samples to discover differentially expressed genes.
Project description:We used single-cell RNA sequencing to characterize the heterogeneity of circulating leukocytes in dogs, then employed the dataset to investigate how primary osteosarcoma (OS) tumors impacted circulating leukocytes.
Project description:Bulk RNA sequencing data of AB1-HA murine mesothelioma tumors from mice treated with tretinoin, immune checkpoint therapy or the combination of tretinoin+immune checkpoint therapy.
