GAPDH and escherichia coli infection: Interestingly, the DEGs encoding the T3SS needle filament protein VscF (Vp_N10_18_0060) and glyceraldehyde-3-phosphate dehydrogenase (gapA, Vp_N10_18_3876) in pathogenic E. coli infection were significantly up-regulated by 5.836- and 2.086-fold, respectively (p < 0.05).
