Fig 1: Western blot analysis of phosphoglucomutase 1 (PGM1; A), malic enzyme 1 (ME1; B), isocitrate dehydrogenase (IDH1; C), and malate dehydrogenase 2 (MDH2; D) protein expression of liver tissue of ducks in the pantothenic acid deficient (PAD) and Control (CON) groups. Loading control, vinculin, was used to normalize the levels of PGM1, ME1, IDH1, and MDH2. Representative Western blots are shown. Values are means with their standard errors. a, b Mean values with unlike letters were significantly different (P < 0.05). Data were analyzed by the Student's t-test.
