Fig. 3From: Betaine affects muscle lipid metabolism via regulating the fatty acid uptake and oxidation in finishing pigThe relative gene expression of key factors involved fatty acid uptake in muscle. mRNA expression was performed by RT-PCR and β-actin was chosen as reference gene. aThe relative expression of FAT/CD36, FATP1, LPL and PPARγ in muscle, (b) The relative expression of FABP3 in muscle. a,bValues without common superscript letters differ significantly (P < 0.05). Low betaine and high betaine represent 1250 mg/kg and 2500 mg/kg betaine addition, respectivelyBack to article page
