Fig. 8From: Mesenchymal stem cells combined with liraglutide relieve acute lung injury through apoptotic signaling restrained by PKA/β-cateninSchematic showing the regulation of apoptosis in MSCs through the PKA/β-catenin pathway. Liraglutide stimulated the expression of PKA by targeting GLP-1R and then motivated the expression of β-catenin, thereby attenuating the expression of Bax, cleaved caspase-9, and cleaved caspase-3 and enhancing the expression of Bcl-2, consequently reducing the apoptosis of MSCsBack to article page
