T1 |
0-182 |
Sentence |
denotes |
Immunosuppressant PG490 (triptolide) inhibits T-cell interleukin-2 expression at the level of purine-box/nuclear factor of activated T-cells and NF-kappaB transcriptional activation. |
T2 |
183-290 |
Sentence |
denotes |
PG490 (triptolide) is a diterpene triepoxide with potent immunosuppressive and antiinflammatory properties. |
T3 |
291-526 |
Sentence |
denotes |
PG490 inhibits interleukin(IL)-2 expression by normal human peripheral blood lymphocytes stimulated with phorbol 12-myristate 13-acetate (PMA) and antibody to CD3 (IC50 of 10 ng/ml), and with PMA and ionomycin (Iono, IC50 of 40 ng/ml). |
T4 |
527-600 |
Sentence |
denotes |
In Jurkat T-cells, PG490 inhibits PMA/Iono-stimulated IL-2 transcription. |
T5 |
601-803 |
Sentence |
denotes |
PG490 inhibits the induction of DNA binding activity at the purine-box/antigen receptor response element (ARRE)/nuclear factor of activated T-cells (NF-AT) target sequence but not at the NF-kappaB site. |
T6 |
804-1003 |
Sentence |
denotes |
PG490 can completely inhibit transcriptional activation at the purine-box/ARRE/NF-AT and NF-kappaB target DNA sequences triggered by all stimuli examined (PMA, PMA/Iono, tumor necrosis factor-alpha). |
T7 |
1004-1196 |
Sentence |
denotes |
PG490 also inhibits PMA-stimulated activation of a chimeric transcription factor in which the C-terminal TA1 transactivation domain of NF-kappaB p65 is fused to the DNA binding domain of GAL4. |
T8 |
1197-1371 |
Sentence |
denotes |
In 16HBE human bronchial epithelial cells, IL-8 expression is regulated predominantly by NF-kappaB, and PG490 but not cyclosporin A can completely inhibit expression of IL-8. |
T9 |
1372-1635 |
Sentence |
denotes |
The mechanism of PG490 inhibition of cytokine gene expression differs from cyclosporin A and involves nuclear inhibition of transcriptional activation of NF-kappaB and the purine-box regulator operating at the ARRE/NF-AT site at a step after specific DNA binding. |
