The risk of malignant transformation of enchondromas (EC) toward central chondrosarcoma is increased up to 35%, while the exact etiology of EC is unknown. The purpose of this research was to authenticate gene signatures during EC and reveal their potential mechanisms in occurrence and Neoangiogenesis has been demonstrated in chondrosarcoma. Anti-angiogenic therapies are being tested in clinical trials for chondrosarcomas. Studies of the underlying mechanisms have been performed almost exclusively in cell lines. We immunostained 20 samples of chondrosarcoma and 20 samples of
Angiogenesis is characteristic of cartilage tumors, not of normal cartilage tissue. In addition to our previous report on differential expression of proangiogenic vascular endothelial growth factor A (VEGF-A) in cartilage tumors, we analyzed the expression of a disintegrin and metalloproteinase with
Chondrocytes within the growth plates acclimatize themselves to a variety of stresses that might otherwise disturb cell fate. The tumor suppressor PTEN (phosphatase and tensin homolog deleted from chromosome 10) has been implicated in the maintenance of cell homeostasis. However, the functions of
In contrast to normal cartilage, which is avascular, angiogenesis is characteristic of cartilage tumors. In this review, we outline the basic principles of angiogenesis with regard to recent findings on differential morphological and molecular aspects of angiogenesis in cartilage tumors, including
As a group, cartilage tumours are the most common primary bone lesions. They range from benign lesions, such as enchondromas and osteochondromas, to malignant chondrosarcoma. The benign lesions result from the deregulation of the hedgehog signalling pathway, which is involved in normal bone
