The effect of hysteroscopic polypectomy on the gene expression of endometrial receptivity markers: HOXA10, HOXA11 and LIF

摘要

The aim of this study is to determine the effect of hysteroscopic polypectomy on themRNA expression levels of the endometrial receptivity markers, namely, homeobox A10 (HOXA10), homeobox A11 (HOXA11) and leukemia inhibitory factor (LIF). Twenty-five reproductive-aged women with endometrial polyps underwent hysteroscopy. Samples were taken at the mid-secretory phase using hysteroscopic polypectomy and 4 months after polypectomy, and the change in mRNA expression levels of normalized HOXA10, HOXA11 and LIF genes were determined using Reverse Transcription Quantitative Real Time?Polymerase Chain Reaction (RT-qPCR). The results show that mRNA levels of HOXA10 and HOXA11 taken prior to surgery and 4 months after the complete hysteroscopic removal of polyps were not significantly different (P=0.79 and P=0.14, respectively). Moreover, a marked difference could not be obtained between preoperative and postoperative endometrial LIF mRNA expression levels (P=0.86). As a conclusion, these results indicate that mRNA levels of HOXA10, HOXA11 and LIF genes, three of molecular markers of endometrial receptivity, are not affected by hysteroscopic polypectomy.
