Abstract

In this study, we investigated the regulation of interleukin-8 (IL-8) gene expression in separated endometrial stromal and epithelial cells of human endometrium. This research was conducted as part of an analysis of the role of these cells in regulating the recruitment of leukocytes to the endometrium. Well-characterized model systems were used to study the regulation of endometrial IL-8 gene expression, namely, stromal cells in monolayer culture after first passage and glandular epithelium in primary culture. The levels of IL-8 mRNA and the accumulation of immunoreactive IL-8 in the medium of endometrial stromal cells is culture increased in a time- and concentration-dependent manner upon treatment with IL-lα, tumor necrosis factor-α, or serum. The effects of IL-lα plus serum on IL-8 mRNA levels were at least additive. Serum treatment caused a modest stimulation of IL-8 gene transcription (evaluated after 6 h of treatment) in endometrial stromal cells, but serum also acted in these stromal cells to prolong the half-life of IL-8 mRNA by more than 2.5-fold. The regulation of the levels of IL-8 mRNA in endometrial epithelial cells is distinctly different from that in stroma. First, the levels of IL-8 mRNA in non-treated epithelial cells in serum-free medium were much greater than those in stromal cells under similar conditions. Second, whereas the levels of IL-8 mRNA in endometrial epithelial cells also increased in response to serum and to IL-1 in the absence of serum, in the presence of serum, 1L-1 treatment caused no appreciable change in the levels of IL-8 mRNA as was the case in endometrial stromal cells.
