CRP and gastric cancer: Notably, among the GC patients after chemotherapy, TrxR activity in CRP group [7.12 (6.08, 8.37) U/mL] was significantly lower than that in CUP group [10.07 (8.19, 11.02) U/mL], suggesting that TrxR activity was markedly reduced when patients benefit from chemotherapy (Fig. 3B).
