HIF1A expression level is dependent on its GC-rich promoter activation. In most cells, HIF1A gene is constitutively expressed in low levels under normoxic conditions, however, under hypoxia , HIF1A transcription is often significantly upregulated. Ver mais Hypoxia-inducible factor 1-alpha, also known as HIF-1-alpha, is a subunit of a heterodimeric transcription factor hypoxia-inducible factor 1 (HIF-1) that is encoded by the HIF1A gene.
