Abstract

BACKGROUND: Uterine leiomyoma and endometriosis are the most common gynecological diseases in women of reproductive age. A number of data indicate that there are common elements in the pathogenesis of these hyperproliferative conditions. This article is devoted to comparative analysis of the role of the WNT4, HOXA10 and TWIST1 genes in the development of uterine leiomyoma and external genital endometriosis. AIM: The aim of this study was to evaluate the frequency of polymorphic variants rs7521902 (WNT4) and rs4721745 (TWIST1) in patients with uterine leiomyoma, external genital endometriosis and in the comparison group; to determine the frequency of rare allelic variants of the HOXA10 gene in patients with external genital endometriosis; and to study the expression of these genes in the endometrium in patients with uterine leiomyoma, EGE and in the comparison group. MATERIALS AND METHODS: The polymorphic variants of the WNT4 and TWIST1 genes were studied by real-time PCR in patients with external genital endometriosis, uterine leiomyoma and in the comparison group. In patients with EGE and women in the comparison group, the second exon of the HOXA10 gene was sequenced. Real-time PCR with reverse transcription analysis of the expression of the WNT4, TWIST1 and HOXA10 genes in endometrial samples from the patients of the study groups was performed. RESULTS: The frequencies of polymorphic variants rs7521902 (WNT4) and rs4721745 (TWIST1) in patients with uterine leiomyoma, external genital endometriosis and in the comparison group did not differ significantly. Minor alleles of the HOXA10 gene were not identified in patients with external genital endometriosis. Expression of the WNT4 gene in the endometrium of patients with external genital endometriosis was independent of menstrual cycle phase and was reduced by 1.9 times compared to the endometrium of women with uterine leiomyoma. Expression of the HOXA10 gene in the endometrium of endometriosis patients on days 20-23 of the menstrual cycle was significantly reduced compared to the women in the comparison group. Expression of the TWIST1 gene was not altered in the endometrium of patients with uterine leiomyoma and external genital endometriosis. CONCLUSIONS: We did not identify associations of the studied polymorphic variants of the WNT4 and TWIST genes and minor variants of the HOXA10 gene with uterine leiomyoma and external genital endometriosis. The expression of the WNT4 and HOXA10 genes is reduced in the endometrium in patients with external genital endometriosis, but not in women with uterine leiomyoma. Changes in expression patterns of the studied genes in the endometrium differ significantly in these two diseases.
