1 In the present studies we found that incubation of human lung fibroblasts with transforming growth factor-beta 1 (TGF-beta 1) potentiated the interleukin-1 beta (IL-1 beta) and/or tumor necrosis factor-alpha (TNF-alpha)-stimulated production of prostaglandin E2 (PGE2).

5 In summary, we demonstrate that the potentiation of PGE2 production by TGF-beta 1 in IL-1 beta and TNF-alpha-treated fibroblasts is the result of transcriptional stimulation of the Cox-2 gene by IL-1 beta and TNF-alpha and the stabilization of the resulting transcripts by TGF-beta 1.
