Numerous molecular abnormalities contribute to the genetic derangements involved in tumorigenesis. Chromosomal translocations are a frequent source of these derangements, producing unique fusion proteins with novel oncogenic properties. EWS/ETS fusions in Ewing sarcoma are a prime example of this, resulting in potent chimeric oncoproteins with novel biological properties and a unique transcript...

The p53 tumour suppressor plays a pivotal role in the prevention of oncogenic transformation. Cancers frequently evade the potent antitumour surveillance mechanisms of p53 through mutation of the TP53 gene, with approximately 50% of all human malignancies expressing dysfunctional, mutated p53 proteins. Interestingly, genetic lesions in the TP53 gene are only observed in 10% of Ewing Sarcomas, w...

Ewing sarcoma is a rare but aggressive disease most common in young adults. This cancer is driven by a unique chimeric fusion oncogene but targeted strategies have been elusive. Here we report the identification of the protein kinase PKC-ß (PRKCB) as a disease-specific druggable target for treatment of Ewing sarcoma. We found that transcriptional activation of PRKCB was directly regulated by th...

The occurrence of Ewing sarcoma as a secondary malignancy is an extremely rare event in long-term cancer survivors. In addition, the occurrence of Ewing sarcoma in the adrenal gland is highly unusual. In this case report, we treated a 20-year-old male patient with cyclophosphamide, doxorubicin, vincristine, dexamethasone, and methotrexate and cytarabine chemotherapy following a diagnosis of Sta...

Ewing sarcoma is the second most common pediatric bone tumor, with three cases per million worldwide. In clinical terms, Ewing sarcoma is an aggressive, rapidly fatal malignancy that mainly develops not only in osseous sites (85%) but also in extra-skeletal soft tissue. It spreads naturally to the lungs, bones, and bone marrow with poor prognosis in the two latter cases. Bone lesions from prima...

Ewing tumor is the second most common bone tumor in children. Its variant, malignant small cell tumor of the thoracopulmonary region, is infrequent in children and extremely rare in adults. A multimodal treatment approach is preferred for this tumor. We describe a rare case of primitive neuroectodermal tumor/Ewing sarcoma arising from the thoracic wall in a 54-year-old man. He underwent extensi...

Bone marrow cells (BMC) are critical to the expansion of the tumor vessel network that supports Ewing sarcoma growth. BMCs migrate to the tumor and differentiate into endothelial cells and pericytes. We recently demonstrated that stromal-derived growth factor 1α (SDF-1α) regulates platelet-derived growth factor B (PDGF-B) and that this pathway plays a critical role in bone marrow-derived pericy...

The review and meta-analysis conducted by Ewing and Cervero (2010) identifies a total of 17 studies that deal with the relationship between vehicle miles traveled (VMT) and land use mix, and a subset of those studies was used as the primary evidence for this brief. The studies that were included in the analysis met two criteria. First, the effect on VMT must have been statistically significant ...
