angiofibroma/hypoxia

OBJECTIVE To examine the expression of hypoxia-inducible factor-1α (HIF-1α) and its related molecules (cellular repressor of E1A-stimulated genes [CREG], osteopontin [OPN], proto-oncogene tyrosine-protein kinase Src [c-Src], and vascular endothelial growth factor [VEGF]) in juvenile nasopharyngeal

OBJECTIVE To examine (1) the molecular angiogenic relationship between endothelial and stromal cells of angiofibromas and how this may elucidate the pathogenesis of angiofibromas and (2) the effects of embolization on the expression of angiotrophic factors and proapoptotic and antiapoptotic factors

Angiogenic factors are discussed to participate in growth and promotion of juvenile nasopharyngeal angiofibroma (JNA). However, only few data are available and mechanisms remain unclear. In the presented study we analysed the expression and subcellular distribution of several angiogenic growth
