Transcriptional expression responses of digestive enzymes to SHMT RNAi. a Responses of trypsin to the depletion of SHMT by RNAi. b Responses of chymotrypsin to the depletion of SHMT by RNAi. c Responses of carboxyprotease to the depletion of SHMT by RNAi. d Responses of serine proteases to the depletion of SHMT by RNAi. The data are shown as means ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001; ns, not significant
