We examined the expression of type I collagen genes in prostaglandin E2 (PGE2)-treated human lung fibroblast cultures. Addition of PGE2 to fibroblast cultures inhibited alpha 1(I) mRNA levels by approx. 25% after 6 h and 60% after 24 h. Further studies showed that dibutyryl cAMP did not inhibit alpha 1(I) mRNA levels and that cycloheximide blocked the inhibitory effect of PGE2. In contrast, PGE2 treatment with or without cycloheximide did not affect alpha 2(I) mRNA levels. Moreover, in vitro translation of RNA derived from untreated and PGE2-treated cells yielded similar amounts of alpha 2(I) collagen peptides. Taken together, these results suggest that PGE2 induces a protein which inhibits alpha 1(I) transcription through distinct regulatory elements not under the control of cAMP and provide further evidence that the type I collagen genes can be discordantly regulated.
