The protective effect of Gln on oxidative stress was quantified by keeping colitis mice, involving Phosphatidylinositol-3-kinase (PI3K)/Protein kinase B (Akt)/mammalian target of Rapamycin (mTOR) signaling pathway, with different medications or distilled water through intragastric administration for 10 consecutive days. The gene discussed is AKT1; the disease is colitis.
