Glucose transporter-1 expression and the antiproliferative effects of 2-deoxy-d-glucose in osteosarcoma models
Osteosarcoma (OSA) is the most common bone tumor in the dog, more common in large to giant breed dogs. 90% of dogs diagnosed with OSA will die of metastatic disease within one year of diagnosis. There have been no great advances in therapy for canine OSA over the last 20 years. Hypoxia in tumors has been associated with an increased resistance to radiation and chemotherapy, and increased metastatic potential. Hypoxia-inducible factor 1-a (HIF-la) is a transcription factor stabilized by hypoxia. Glucose transporter 1 (GLUT-1), a downstream product of HIF-la pathway activation, is over-expressed ...
