Project description:This was a prospective clinical trial testing the ability of gene expression models of drug sensitivity that were developed in human and canine cell lines and applied to outcomes in dogs treated with adjuvant carboplatin and/or doxorubicin. Tumor samples were collected prospectively, and gene expression analysis was conducted using Affymetrix Canine Genome 2.0 Arrays.

Project description:We developed a method using canine osteosarcoma in mouse xenografts to distinguish tumor-derived from host-response exosomal mRNAs. The model allows for the identification of canine osteosarcoma-specific gene signatures by RNA sequencing and a species-differentiating bioinformatics pipeline. An osteosarcoma-associated signature consisting of five gene transcripts was validated in dogs with osteosarcoma. Serum/plasma exosomes were isolated from 53 dogs in distinct clinical groups (“healthy”, “osteosarcoma”, “other bone tumor”, or “non-neoplastic disease”). Pre-treatment samples from osteosarcoma cases were used as the training set and a validation set from post-treatment samples was used for testing, classifying as “osteosarcoma–detected” or “osteosarcoma–NOT detected”. Dogs in a validation set whose post-treatment samples were classified as “osteosarcoma–NOT detected” had longer remissions, up to 15 months after treatment. In conclusion, we identified a gene signature predictive of molecular remissions with potential applications in the early detection and minimal residual disease settings. These results provide proof-of-concept for our discovery platform and its utilization in future studies to inform cancer risk, diagnosis, prognosis, and therapeutic response.

Project description:Pulmonary metastasis continues to be the most common cause of death in osteosarcoma. Indeed, the 5-year survival for newly diagnosed osteosarcoma patients has not significantly changed in over 20 years. Further understanding of the mechanisms of metastasis and resistance for this aggressive pediatric cancer is necessary. Pet dogs naturally develop osteosarcoma providing a novel opportunity to model metastasis development and progression. Given the accelerated biology of canine osteosarcoma, we hypothesized that a direct comparison of canine and pediatric osteosarcoma expression profiles may help identify novel metastasis-associated tumor targets that have been missed through the study of the human cancer alone. Collectively, these data support the strong similarities between human and canine osteosarcoma and underline the opportunities provided by a comparative oncology approach as a means to improve our understanding of cancer biology and therapy.

Project description:Osteosarcoma is the most common primary bone tumours of dogs. Canine osteosarcoma contains a sub-population of cancer stem cells. Here we used canine-specific microarrays to compare the global gene expression profiles of osteosarcoma stem cells to adherent cancer cells and canine mesenchymal stem cells.

Two datasets consisting of canine osteosarcoma tumors, canine osteosarcoma cell lines, and three normal tissues and an analogous human dataset were used to define the similarity between human and canine osteosarcoma. A third dataset, human osteosarcoma with outcome data, was then used to suggest that some of the differences between the canine and human osteosarcoma were, perhaps, related to survival.
