Heme oxygenase-1 alleviates advanced glycation end product-induced oxidative stress, inflammatory response and biological behavioral disorders in rat dermal fibroblasts.

ABSTRACT: Advanced glycation end products (AGEs) are involved in delaying the wound healing of diabetic foot ulcers. The present study investigated the effects of heme oxygenase-1 (HO-1) on oxidative stress, inflammatory insult and biological behaviors in rat dermal fibroblasts in the presence of AGEs. Rat dermal fibroblasts were cultured in the presence of AGEs (100 µg/ml), glucose (1.0 g/l or 4.5 g/l), hemin (5 µM) and chromium mesoporphyrin (CrMP; 20 µM). A bilirubin kit, reverse transcription-quantitative PCR and western blotting were used to measure the activity and mRNA and protein levels of HO-1, respectively. ELISA kits were used to measure the levels of reactive oxygen species (ROS), malondialdehyde (MDA), 8-hydroxydeoxyguanosine (8-OHdG), TNF-α, IL-6, IL-1β and the viability and collagen (
