Alanyl-Glutamine Inhibits the Epithelial-Mesenchymal Transition of Airway Epithelial Cells in Asthmatic Mice via DPP4-SIRT1 Pathway

Alanyl-glutamine (Ala-Gln) is a compound known for its protective effects in various tissue injuries. However, its role in asthma-related lung injuries remains underexplored. This study investigates the mechanisms by which Ala-Gln modulates sDPP4-induced airway epithelial-mesenchymal transition and ovalbumin (OVA)-induced asthma in a mouse model.
