We found stable phospho-AKT during infection (lane 2–4, third panel, Fig. 5b), and this phospho-AKT was further augmented in presence of supplementary tryptophan (lane 5–7, third panel, Fig. 5b), because increased melatonin (Supplementary Figure S2d) was able to maintain cell alive. The gene discussed is AKT1; the disease is infection.
