title: Expression of growth-regulated oncogene beta in an endometrial epithelial cell line, HHUA, and cultured human endometrial cells.
abstract: It has been demonstrated that human endometrial epithelial cells (EEC) and stromal cells (ESC) produce a variety of chemokines in vivo and in vitro. Growth-regulated oncogene (GRO)beta, which belongs to the CXC chemokine family, is a potent chemoattractant for neutrophils. To evaluate the regulation of GRO beta expression in the endometrium, the production of GRO beta by an EEC line, HHUA, and cultured ESC stimulated with various inflammatory mediators was examined by using an enzyme-linked immunosorbent assay. Unstimulated HHUA and ESC constitutively secreted GRO beta. Interleukin-1 beta, tumor necrosis factor-alpha and interferon-gamma significantly stimulated the expression of GRO beta by HHUA and ESC. Lipopolysaccharide also stimulated the expression of GRO beta by ESC, but not by HHUA. It is suggested that, in the human endometrium, the regulation of GRO beta expression is distinct from that of other CXC chemokines expressed in the endometrium, such as GRO alpha and interleukin-8. The modulation of the GRO beta concentration in the endometrium by inflammatory mediators may contribute to the normal and pathological processes of human reproduction by regulating the trafficking of neutrophils into the endometrium.
