“…HIF-1α is an important transcription factor that regulates glucose uptake and glycolysis at the transcriptional level (Huang et al, 2012 ; Harris et al, 2014 ; Masoud and Li, 2015 ). Several studies have shown that HIF-1α upregulates glucose transporters (GLUT1, GLUT3, GLUT4; Toberer et al, 2020 ), glycolysis enzyme (HK2; Cao et al, 2020 ; Shen et al, 2020 ), pro-angiogenic factors (HO-1, VEGF; Choi et al, 2006 ). Whereas, downregulation of HIF-1α suppressed the target genes and protein expressions, such as GLUT1, GLUT3, and HK2 (Liu et al, 2008 ; Lee et al, 2019 ).…”
