Expression of HIF-1 alpha is regulated by cellular oxygen level alterations as well as in oxygen-independent manner via different cytokines (through the PI3K-AKT-mTOR pathway), growth factors, oncogenic activation, or loss of tumor suppressor function etc. In normoxic cells, HIF-1 alpha is proline hydroxylated leading to a conformational change that promotes its binding to the VLH (von Hippel Lindau) protein E3 ligase complex; ubiquitination and followed by rapid proteasomal degradation. Hypoxia as well as chemical hydroxylase inhibitors (desferrioxamine, cobalt etc.) inhibit HIF-1 alpha degradation and lead to its accumulation in the cells, whereas, contrastingly, HIF-1 beta\/ARNT (AhR nuclear translocator) remains stable under both conditions. Besides their critical role in hypoxic response, HIFs regulates the transcription of genes responsible for angiogenesis, erythropoiesis\/iron-metabolism, glucose metabolism, cell proliferation\/survival, adipogenesis, carotid body formation, B lymphocyte development and immune reactions.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhere multiple assay formats are possible, align the antibody format, host\/isotype, and listed applications with your detection system and controls to support clear interpretation of signal.\u003c\/p\u003e \u003ch2\u003eBiological background\u003c\/h2\u003e \u003cp\u003eIn this catalog, HIF1 is positioned within \u003cstrong\u003eCell Signaling, Tumor\u003c\/strong\u003e research contexts.
