چکیده انگلیسی
Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors implicated in lipid metabolism. In this study, the full-length cDNA of canine PPARβ and γ were sequenced, and expression of PPARs was evaluated in normal tissues and primary cultures of adipocytes in dogs, followed by investigations for polymorphisms of canine PPARγ. Comparison of the deduced amino acid sequences of canine PPARβ and γ cDNA with that of human PPARβ and γ cDNA revealed 95.9% and 98.2% identity, respectively. PPARβ expression was ubiquitous and high PPARγ expression was detected in the subcutaneous and omental adipose tissues, spleen and large intestine. Canine PPARγ mRNA expression in cultured adipocytes began to increase from 4 days after induction of differentiation, and increased nearly ninefold within 10 days after induction of differentiation. Although expression level of PPARα was low in the cultured adipocytes, it slightly increased within 10 days. In contrast, expression of PPARβ showed only small variations during adipocyte differentiation, though expression levels were relatively high. These results suggest that PPARγ may play an important role in adipocyte differentiation in dogs. Investigations for polymorphisms of PPARγ revealed a silent polymorphism, C1362T, in 3 of 92 dogs.
