Fig. 1. Activities of some key enzymes in glycolysis or closely related pathways before and during cold treatment. (C) and (B) represent (GSHþ) cells and (GSH) cells, respectively.
Panel A: pyruvate kinase (PK) activities of (GSHþ) cells and (GSH) cells before (A1) and during (A2) cold treatment. Panel B: glyceraldehyde-3-phophate dehydrogenase (GAPDH)
activities of (GSHþ) cells and (GSH) cells before (B1) and during (B2) cold treatment. Panel C: lactate dehydrogenase (LDH) activities of (GSHþ) cells and (GSH) cells before (C1) and
during (C2) cold treatment. Error bars indicate standard deviations (n ¼ 3). Statistically significant differences (p < 0.05) were determined by Student’s t-test and are indicated with
asterisks.
