High Glucose Stimulates Expression of MFHAS1 to Mitigate Inflammation via Akt/HO-1 Pathway in Human Umbilical Vein Endothelial Cells

Inflammation. 2018 Mar;41(2):400-408. doi: 10.1007/s10753-017-0696-0.

Abstract

Hyperglycemia is a highly dangerous factor to various diseases, even resulting in death of people. Inflammation plays a key role in this process. The aim of this study was to explore the role of malignant fibrous histiocytoma amplified sequence 1 (MFHAS1) in high-glucose induced inflammation. Our research showed that high glucose stimulated the expression of MFHAS1, and overexpression of MFHAS1 can attenuate high-glucose induced inflammation in endothelial cells by decreasing the secretion of cytokines interleukin-1β (IL-1β), interleukin-1α (IL-1α), adhesion molecule intercellular adhesion molecule-1 (ICAM), interleukin-6 (IL-6), interleukin-8 (IL-8), and chemokine ligand 1 (CXCL-1). Furthermore, we found that MFHAS1 promoted the phosphorylation of Akt and the expression of heme oxygenase-1 (HO-1). Our results indicated that MFHAS1 deadened high-glucose induced inflammation by activating AKT/HO-1 pathway, suggesting that MFHAS1 may act as a new therapeutic target of diabetes mellitus.

Keywords: AKT; HO-1; MFHAS1; high glucose; inflammation.
