Differential Expression and Activation of a Family of Murine Peroxisome Proliferator-Activated Receptors
To gain insight into the function of peroxisome proliferator-activated receptor (PPAR) isoforms in mammals, we have cloned and characterized two PPARα-related cDNAs (designated PPARγ and -δ, respectively) from mouse. The three PPAR isoforms display widely divergent patterns of expression during embr...

Summary: | To gain insight into the function of peroxisome proliferator-activated receptor (PPAR) isoforms in mammals, we have cloned and characterized two PPARα-related cDNAs (designated PPARγ and -δ, respectively) from mouse. The three PPAR isoforms display widely divergent patterns of expression during embryogenesis and in the adult. Surprisingly, PPARγ and -δ are not activated by pirinixic acid (Wy 14,643), a potent peroxisome proliferator and activator of PPARα. However, PPARγ and -δ are activated by the structurally distinct peroxisome proliferator LY-171883 and linoleic acid, respectively, indicating that each of the isoforms can act as a regulated activator of transcription. These data suggest that tissue-specific responsiveness to peroxisome proliferators, including certain fatty acids, is in part a consequence of differential expression of multiple, pharmacologically distinct PPAR isoforms. |
