In particular, there were 37 targets involved in the PI3K-Akt signaling pathway (hsa04151), and the associated targets included AKT1, BDNF, GDNF, GSK3B, PTEN, TP53, VEGFA, etc. The above results pointed out that multiple mechanisms were involved in the pathogenesis of depression. The gene discussed is AKT1; the disease is depressive symptom measurement.
