摘要
Objective To study HOXAll expression and its correlation with that of the progesterone receptor (PR) gene in human endometriumMethods In situ hybridization and semi-quantitative RT-PCR were used. Results HOXAll mRNA was detected in both stromal and glandular cells of normal endometrium by in situ hybridization. But the expression levels in the glandular cells had a dramatic decline or even disappearance at mid-secretory stage. Semi-quantitative RT-PCR analysis, however, demonstrated that the total expression levels of HOXAll mRNA were markedly increased in the mid-secretory endometrium, which suggested that there was an increased expression in stromal cells. Similar results were obtained for PR gene expression in human endometrium by in situ hybridization and semi-quantitative RT-PCR analysis.Conclusion HOXAll gene spatial and temporal expression patterns were similar to that of PR gene in endometrium across menstrual cycle, and HOXAll was closely related to the endometrial proliferation and differentiation during menstrual cycle, especially the establishment of receptive status in implantation.
