Cell apoptosis,proliferation and migration were measured by annexin-V and PI double staining,MTT degradation assay and cell monolayer scratch assays,*** At 8 h after treatment,HO-1 and CHOP expression in CsA-treated cells increased significantly compared to untreated *** promoted apoptosis and inhibited cell proliferation and migration of the *** increased HO-1 protein and mRNA expressions *** hemin decreased CsA -induced CHOP expression,it did not prevent CsA -induced apoptosis,proliferation and migration inhibitions compared to untreated ***-releasing molecule CORM-2 did not affect biological properties and protein expressions of the cells without CsA treatment although it decreased migration of the ***,it blocked CsAinduced cell proliferation inhibition, apoptosis and CHOP expression although it did not change cell migration,ATF-6 expression and activation of CsA-treated *** Pharmacological dose of Cs
