Web3 de set. de 2024 · Hypoxia-inducible factor 1 (HIF1) is a transcription factor that exerts pivotal regulatory role in oxygen homeostasis by controlling both the delivery and utilization of oxygen [Citation 6]. HIF1α is the functional subunit of HIF1 and important to the HIF1 activation under hypoxia condition [ Citation 7 ]. Web1 de jan. de 2024 · Previous research has shown that microtubule-regulated HIF1α nuclear translocation is a key factor for HIF1 activation under hypoxia. In this review, we summarize experimental reports on the role of microtubule-associated factors, such as microtubule, dynein, and dynein adaptor protein, in nuclear translocation of HIF1α.

WebFibroblasts harboring activated HIF1 a showed a dramatic reduction in Cav-1 levels and a shift towards aerobic glycolysis, as evidenced by a loss of mitochondrial activity, and an increase in lactate production. Activated HIF1a also induced BNIp3 and BNIp3L expression, markers for the autophagic destruction of mitochondria. WebHypoxia-inducible factor 1 (HIF1) is a heterodimeric transcription factor that plays a critical role in the cellular response to hypoxia (1). The HIF1 complex consists of two subunits, HIF-1α and HIF-1β, which are basic helix-loop-helix proteins of the PAS (Per, ARNT, Sim) family (2). HIF1 regulates the transcription of a broad range of genes ... Web4 de dez. de 2024 · HIF1 in mediating this isoform switch. Our study provides a new, detailed characterization of the early transcriptome after MI. From this analysis, we identified an HIF1-mediated alternative splicing event in the PKM gene. Pkm1 and Pkm2 play distinct roles in glycolytic metabolism and the upregulation of Pkm2 is likely to have … the qwant
