Web7 de jan. de 2024 · Albendazole inhibited growth of NSCLC cells by suppressing HIF-1α-dependent glycolysis and VEGF expression. Albendazole (ABZ) has an anti-tumor ability and inhibits HIF-1α activity. HIF-1α is associated with glycolysis and vascular endothelial cell growth factor (VEGF) expression, which plays an important role in cancer progression.

WebFigure 1. Induction of glycolysis by hypoxia is dependent on growth factor signals. (A) Cells were cultured in the presence or absence (3 wk) of IL-3.Following 24 h incubation at 21% O 2 or 1.5% O 2, cellular glucose utilization was measured by the conversion of 5-3 H-glucose to 3 H 2 O. Data represent mean of three independent experiments ± SD. (B) Glucose … Web1 de abr. de 2024 · For example, HIF-1 activation which upregulates glycolysis, occurs at low doses of ROS (H 2 O 2) while higher doses of ROS cause HIF-1 inactivation thereby decreasing glycolysis. Inactivation of PKM2, which causes the deviation towards PPP, requires higher doses of ROS and longer exposure times compared to what is required …
