Autocrine VEGF/VEGFR1 signaling in a subpopulation of cells associates with aggressive osteosarcoma.
UNLABELLED Osteosarcoma is the most common primary bone malignancy and accounts for more than half of primary skeletal malignancies in children and young adults. Although vascular endothelial growth factor (VEGF) expression in osteosarcoma has been associated with poor outcome, its role in the pathogenesis of osteosarcoma remains controversial. Here, VEGF and VEGFR1 expression in both human and...
متن کاملAggressive chondroblastic osteosarcoma in a dog: A case report
Canine osteosarcoma (OS) or osteogenic sarcoma is an aggressive tumor of the skeletal system, associated with a rapid progression and guarded prognosis. The osteosarcomas, mostly arise from the appendicular skeleton while axial OS (osteosarcoma of flat bones) are less reported in the majority of large breeds. This report describes complete para-clinical investigations of an aggressive chondrobl...
متن کاملThe Growth and Aggressive Behavior of Human Osteosarcoma Is Regulated by a CaMKII-Controlled Autocrine VEGF Signaling Mechanism
Osteosarcoma (OS) is a hyperproliferative malignant tumor that requires a high vascular density to maintain its large volume. Vascular Endothelial Growth Factor (VEGF) plays a crucial role in angiogenesis and acts as a paracrine and autocrine agent affecting both endothelial and tumor cells. The alpha-Ca2+/Calmodulin kinase two (α-CaMKII) protein is an important regulator of OS growth. Here, we...
متن کاملNotch Signaling is Associated with ALDH Activity and an Aggressive Metastatic Phenotype in Murine Osteosarcoma Cells
Osteosarcoma (OS) is the most common primary malignancy of bone, and pulmonary metastatic disease accounts for nearly all mortality. However, little is known about the biochemical signaling alterations that drive the progression of metastatic disease. Two murine OS cell populations, K7M2 and K12, are clonally related but differ significantly in their metastatic phenotypes and therefore represen...
متن کاملMicroRNA-155 influences B-cell receptor signaling and associates with aggressive disease in chronic lymphocytic leukemia.
High-level leukemia cell expression of micro-RNA 155 (miR-155) is associated with more aggressive disease in patients with chronic lymphocytic leukemia (CLL), including those cases with a low-level expression of ζ-chain-associated protein of 70 kD. CLL with high-level miR-155 expressed lower levels of Src homology-2 domain-containing inositol 5-phosphatase 1 and were more responsive to B-cell r...
