1Hypoxia increases adipogenesis and affects adipocytokine production in orbital fibroblasts-a possible explanation of the link between smoking and Graves' ophthalmopathy显示文摘AIM:To assess the effects of hypoxia on human orbital fibroblasts(OF)on adipogenesis and adipocytokine production.METHODS:Human OF were derived from tissues obtained from patients with Graves'ophthalmopathy(GO)and from patients without known thyroid diseases undergoing blepharoplasty.The OF were cultured separately under normoxic and hypoxic conditions.Comparisons of adipocytokine concentrations using multiplex ELISA and lipid accumulation in the cells using Oil Red O staining were subsequently performed.RESULTS:There was increased adipogenesis in OF from GO subject when exposed to hypoxic culture conditions.This was not observed in OF from normal controls.Hypoxia led to an increase in leptin and a decrease in MCP-1 secretion in OF cultures.CONCLUSION:Hypoxia induces adipogenesis in OF and may represent a mechanism by which smoking contributes to deterioration of GO.We also found novel changes to leptin and MCP-1 production in OF cultures exposed to hypoxia suggesting important roles of these cytokines in the disease process.Chiaw Ling Chng Oi Fah Lai Charmaine Sze-Min Chew Yu Pei Peh Stephanie Man-Chung Fook-Chong Lay Leng Seah Daphne Hsu-Chin Khoo 2014International Journal of Ophthalmology(English edition)2014,7,3:10
