- Abstract
Chlorogenic acid as an antioxidant exists widely in edible and medicinal plants, and can protect cell against apoptosis induced by oxidative stress. However, its molecular mechanisms remain largely unknown. Here, we showed that Chlorogenic acid suppressed reactive oxygen species increase by activation of Akt phosphorylation,and increased FOXO family genes and anti-apoptotic protein Bcl-2 expression in MSCs culturing under oxidative stress. In addition, PI-3Kinase Inhibitor (2-(4-Morpholinyl)-8-phenyl-4H-1-benzopyran-4-one, LY294002) could suppress the Chlorogenic acid-induced: (1) the cellular protective role, (2) the increase of the FOXO family genes expression, (3) increased expression of Bcl-2. These results suggested that Chlorogenic acid protected MSCs against apoptosis via PI3K/AKT signal and FOXO family genes., (Copyright © 2011 Elsevier B.V. All rights reserved.)
