In particular, key amino acids or intermediate metabolites involved in de novo or salvage synthesis of glutathione (GSH), particularly cysteine (Cys), - glutamylcystine (-GC), glutamine (Gln), glutamate (Glu), and GSH itself, were significantly decreased in LDHB KD A549 cells compared with those in control A549 cells expressing control siRNA (siNT) ( Figure 1c, d )
