WebJan 1, 2009 · Glucokinase (hexokinase IV) has a major role in the control of blood glucose homeostasis because it is the predominant hexokinase expressed in the liver, has a very high control strength on hepatic glucose disposal (), and is the glucose sensor for insulin secretion in pancreatic β-cells ().Glucokinase is currently considered a strong candidate … WebHexokinase is responsible for glucose phosphorylation, a process fundamental to regulating glucose uptake. In some tissues, hexokinase translocates to the mitochondria, thereby increasing its efficiency and decreasing its susceptibility to product inhibition. It may also decrease free radical formation in the mitochondria and prevent apoptosis.

WebApr 14, 2024 · In CD4 + T cells, the decreased expression of HIF1α inhibits the expression of the glycolytic genes encoding GLUT1, hexokinase 2 (HK2), and downstream metabolic rate-limiting enzymes. This leads to significant downregulation of the glycolysis level of CD4 + T cells, thus inhibiting the differentiation of naive CD4 + T cells into Th17 cells [ 66 ]. WebThe aim of the study was to explore whether hexokinase 1 (HK1) is involved in the inhibition of inflammation mediated by nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) signalling pathway in the development of apical periodontitis (AP). Methodology. Human AP tissues and normal control tissues were collected in the clinic.
