Differential expression of PPAR gamma1 and gamma2 isoforms in human adipose tissue.
One of the essential factors for adipogenesis, peroxisome proliferator activated receptor gamma (PPAR gamma), is classified into two isoforms, gamma1 and gamma2 encoded by a single PPAR gamma gene. To examine the mode of expressions of both the PPAR gamma1 and gamma2 isoforms in human adipose tissue, we cloned a partial cDNA of the human PPAR gamma2 (hPPAR gamma2) from a human adipose tissue cDNA library. The sequence encoded an additional 28 amino acids amino-terminal to the first ATG codon of hPPAR gamma1. The simultaneous quantitation of hPPAR gamma1 and gamma2 mRNA in subcutaneous or visceral (mesenteric) fat tissue from 10 different individuals was performed by an RNase protection assay and revealed a relatively higher expression of gamma1 than gamma2 in all specimens examined.
