Modulation of the expression of peroxisome proliferators-activated receptors in human fibroblasts
Abstract:
To determine the levels of peroxisome proliferators-activated receptors (PPARs) in normal and adhesion fibroblasts, we utilized real-time reverse transcription-polymerase chain reaction to measure messenger RNA (mRNA) levels in fibroblasts from normal peritoneum and adhesions from five patients in both the presence or absence of dichloroacetic acid (DCA) and a cyclooxygenase-2 (COX-2) inhibitor, NS-398. Peroxisome proliferators-activated receptor alpha, PPARbeta, PPARgamma1, and PPARgamma2 mRNA are all present in normal peritoneal and adhesion fibroblasts, and selectively rose in response to hypoxia and either DCA or NS-398.

Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...
