Disruption of sulfhydryl homeostasis, which resulted in ER stress, accumulation of ubiquitinated proteins and subsequent ER dilation, contributed to peroxisome proliferator-activated receptor gamma (PPARgamma)-independent cell death by 15d-PGJ2.

15-deoxy-delta (12,14)-PGJ (2)(15d-PGJ (2)) is a natural ligand that activates the peroxisome proliferators-activated receptor (PPAR) gamma, a member of nuclear receptor family implicated in regulation of lipid metabolism and adipocyte differentiation.
Although cycloheximide reversed 15d-PGJ (2)-mediated inhibition of Stat3 activation, actinomycin D had no effect on 15d-PGJ (2)-mediated inhibition of IL-6 signaling, indicating that inhibition of IL-6 signaling occur independent of de novo gene expression.

To investigate the effect of dehydroepiandrosterone (DHEA) on intracellular mRNA levels of peroxisome proliferator-activated receptors (PPARs) and PPAR-gamma coactivators (PGCs), we conducted a quantitative real-time RT-PCR study using HepG2 cells.

CONCLUSIONS: Rosiglitazone directly regulates transcription of ATGL, likely through a PPARgamma-mediated mechanism.
Finally, we found that rosiglitazone increased ATGL mRNA levels in 3T3-L1 adipocytes in the presence of cycloheximide, an inhibitor of protein synthesis, suggesting that rosiglitazone regulation of ATGL occurs at the transcriptional level.
