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.

Project description:This SuperSeries is composed of the following subset Series: GSE16087: Gene expression profiles of canine osteosarcoma GSE16088: Gene expression profiles of human osteosarcoma GSE16091: Gene expression profiles of human osteosarcoma, set2 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. 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.

Project description:Osteosarcoma is a rare maligancy seen in pediatric human patients but frequently seen in canine patients. Because of the increased frequecy of osteosarcoma in canines it is becoming recognized as an informative model for human osteosarcoma. Therefore in a better effort to understand the moclular features common to both human and canine osteosracoma a transcriptional mRNA seq dataset of 186 canine osteosarcoma primary tumors

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. Canine osteosarcoma spheres were isolated by their ability to form tumourspheres. Spheres, adherent cells and mesenchymal stem cells were harvested and used for RNA extraction and hybridisation on Affymetrix microarrays (Canine 2.0). Four biological replicates of each sample were included.

Project description:Osteosarcoma is an aggressive tumor of the bone that primarily affects young adults and adolescents. Osteosarcoma is characterized by genomic chaos and heterogeneity. While inactivation of tumor suppressor p53 TP53 is nearly universal other high frequency mutations or structural variations have not been identified. Despite this genomic heterogeneity, key conserved transcriptional programs associated with survival have been identified across human, canine and induced murine osteosarcoma. The epigenomic landscape, including DNA methylation, plays a key role in establishing transcriptional programs in all cell types. The role of epigenetic dysregulation has been studied in a variety of cancers but has yet to be explored at scale in osteosarcoma. Here we examined genome-wide DNA methylation patterns in 24 human and 44 canine osteosarcoma samples identifying groups of highly correlated DNA methylation marks in human and canine osteosarcoma samples. We also link specific DNA methylation patterns to key transcriptional programs in both human and canine osteosarcoma. Building on previous work, we built a DNA methylation-based measure for the presence and abundance of various immune cell types in osteosarcoma. Finally, we determined that the underlying state of the tumor, and not changes in cell composition, were the main driver of differences in DNA methylation across the human and canine samples. Significance: This is the first large scale study of DNA methylation in osteosarcoma and lays the ground work for the exploration of DNA methylation programs that help establish conserved transcriptional programs in the context of different genomic landscapes.
