“…KEGG analysis also revealed that p53 and PI3K-AKT signaling pathways, reportedly involved in ROS-mediated apoptosis, were altered in the WL-808 + laser group. It has been confirmed that p53 activation and PI3K/AKT inactivation can induce cell apoptosis by regulating the downstream mitochondrial apoptotic signaling pathway [ 35 , 36 , 40 ]. Moreover, western blotting analysis further confirmed that compared to the control group, PDT with WL-808 enhanced the expression of p53 and decreased the expression of PI3K and p -AKT in the tendon injury sites.…”
