چکیده انگلیسی
Hypoxic environment in solid tumor is known to favor cell survival and to initiate the formation of new capillaries. In this work, we identified by 2D gel analysis 94-kDa glucose-regulated protein (GRP94) as being upregulated in human endothelial cells in response to hypoxia. Three putative hypoxia responsive elements (HRE) were found in the GRP94 promoter. Competition experiments of HIF-1 DNA binding using specific probes containing each HRE sequence of the GRP94 promoter clearly evidenced that HIF-1 binds these sequences with high affinity. The human GRP94 promoter was then cloned upstream of the luciferase gene and showed enhanced activity in hypoxic conditions. Mutation of two of the three HREs present in this promoter completely inhibited the hypoxia-induced increase in luciferase activity.
