GAPDH and cryptosporidiosis: Additionally, significantly upregulated glycolysis pathway proteins such as glyceraldehyde-3-phosphate dehydrogenases from yeasts (P00360, cFC = 11.02) and Lactobacillus (A0A062X383, cFC = 1.41) were seen in the jejunum–ileum section during cryptosporidiosis (Figure 5A, Supporting Dataset 1).
