| T1 |
0-179 |
Sentence |
denotes |
Peroxisome proliferator-activated receptor alpha negatively regulates the vascular inflammatory gene response by negative cross-talk with transcription factors NF-kappaB and AP-1. |
| T2 |
180-310 |
Sentence |
denotes |
Interleukin-6 (IL-6) is a pleiotropic cytokine, whose plasma levels are elevated in inflammatory diseases such as atherosclerosis. |
| T3 |
311-587 |
Sentence |
denotes |
We have previously reported that peroxisome proliferator-activated receptor alpha (PPARalpha) ligands (fibrates) lower elevated plasma concentrations of IL-6 in patients with atherosclerosis and inhibit IL-1-stimulated IL-6 secretion by human aortic smooth muscle cells (SMC). |
| T4 |
588-792 |
Sentence |
denotes |
Here, we show that aortic explants isolated from PPARalpha-null mice display an exacerbated response to inflammatory stimuli, such as lipopolysaccharide (LPS), as demonstrated by increased IL-6 secretion. |
| T5 |
793-990 |
Sentence |
denotes |
Furthermore, fibrate treatment represses IL-6 mRNA levels in LPS-stimulated aortas of PPARalpha wild-type, but not of PPARalpha-null mice, demonstrating a role for PPARalpha in this fibrate action. |
| T6 |
991-1063 |
Sentence |
denotes |
In human aortic SMC, fibrates inhibit IL-1-induced IL-6 gene expression. |
| T7 |
1064-1180 |
Sentence |
denotes |
Furthermore, activation of PPARalpha represses both c-Jun- and p65-induced transcription of the human IL-6 promoter. |
| T8 |
1181-1378 |
Sentence |
denotes |
Transcriptional interference between PPARalpha and both c-Jun and p65 occurs reciprocally, since c-Jun and p65 also inhibit PPARalpha-mediated activation of a PPAR response element-driven promoter. |
| T9 |
1379-1548 |
Sentence |
denotes |
This transcriptional interference occurs independent of the promoter context as demonstrated by cotransfection experiments using PPARalpha, p65, and c-Jun Gal4 chimeras. |
| T10 |
1549-1741 |
Sentence |
denotes |
Overexpression of the transcriptional coactivator cAMP-responsive element-binding protein-binding protein (CBP) does not relieve PPARalpha-mediated transcriptional repression of p65 and c-Jun. |
| T11 |
1742-1872 |
Sentence |
denotes |
Finally, glutathione S-transferase pull-down experiments demonstrate that PPARalpha physically interacts with c-Jun, p65, and CBP. |
| T12 |
1873-2107 |
Sentence |
denotes |
Altogether these data indicate that fibrates inhibit the vascular inflammatory response via PPARalpha by interfering with the NF-kappaB and AP-1 transactivation capacity involving direct protein-protein interaction with p65 and c-Jun. |
