    Published 2022-05-01
    “…ObjectiveTo explore the effects of osthole on renal tubular epithelial cell damage and Nrf2/HO-1 signal pathway induced by high glucose,hypoxia and reoxygenation.MethodsHuman renal tubular epithelial cells HK-2 were cultured in high-glucose medium and subjected to hypoxia-reoxygenation treatment to establish a cellular model.CCK-8 experiment was utilized for detecting the effects of 0,10,20,40,80,160 µg/ml osthole on its growth and screen the optimal concentration.HK-2 cells were divided into control,model,osthole (80 µg/ml),ML385 (Nrf2 inhibitor,20 nmol/ml) and osthole (80 µg/ml)+ML385 (20 nmol/ml) groups.Except for control group,the other groups were induced for establishing cellular models.After high glucose,hypoxia and reoxygenation,CCK-8 experiment was utilized for detecting cellular viability in each group.Kits were employed for measuring the levels of reactive oxygen species (reactive oxygen species,ROS),glutathione peroxidase (GSH-Px),malondialdehyde (MDA),lactate dehydrogenase (LDH),tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6) and interleukin-1β (IL-1β); Immunofluorescence for detecting the expression of Nrf2/HO-1 pathway protein; Western blot for detecting the expression of Nrf2/HO-1 pathway protein.ResultsCompared with control group,HK-2 cellular viability (100±0 <italic>vs</italic> 43.47±6.14),cellular GSH-Px level (9.53±1.64 <italic>vs</italic> 3.25±0.32) and cellular Nrf2 protein (1.78±0.30 <italic>vs</italic> 0.89±0.12) were markedly down-regulated in model group (all <italic>P</italic>&lt;0.05); the levels of ROS (1.13±0.17 <italic>vs</italic> 6.52±1.03) and TNF-α spiked markedly (all <italic>P</italic>&lt;0.05).Compared with model and osthole + ML385 groups,HK-2 cellular viability (43.47±6.14,44.83±7.06 <italic>vs</italic> 87.76±9.42),cellular GSH-Px level (3.25±0.32,3.27±0.38 <italic>vs</italic> 9.07±1.78) and cellular Nrf2 protein (0.89±0.12,0.90±0.18 <italic>vs</italic> 1.74±0.26) rose in osthole group (<italic>P</italic>&lt;0.05); ROS (6.52±1.03,6.47±0.96 <italic>vs</italic> 1.59±0.21) and TNF-α declined (both <italic>P</italic>&lt;0.05); HK-2 cellular viability (43.47±6.14,44.83±7.06 <italic>vs</italic> 24.80±3.79),cellular GSH-Px level (3.25±0.32,3.27±0.38 <italic>vs</italic> 0.88±0.15) and cellular Nrf2 protein (0.89±0.12,0.90±0.18 <italic>vs</italic> 0.30±0.05) decreased in ML385 group (all <italic>P</italic>&lt;0.05); ROS (6.52±1.03,6.47±0.96 <italic>vs</italic> 9.76±2.02) and TNF-α increased (all <italic>P</italic>&lt;0.05).ConclusionOsthole can up-regulate the expression of Nrf2/HO-1 signaling pathway protein,suppress ROS and inflammatory factors production induced by high glucose,hypoxia and reoxygenation,thereby relieving oxidative stress and inflammation and lessening the damage of renal tubular epithelial cells.…”
