Analysis of VEGF, IGF1/2 and the Long Noncoding RNA (lncRNA) H19 Expression in Polish Women with Endometriosis

Abstract

The coordinated action of VEGF, IGF1/2 and H19 factors influences the development of endometriosis. The aim of this study was to analyze the expression level of these genes in patients with endometriosis. The study group consisted of 100 patients who were diagnosed with endometriosis on laparoscopic and pathological examination. The control group consisted of 100 patients who were found to be free of endometriosis during the surgical procedure and whose eutopic endometrium wasnormal on histopathological examination. These patients were operated on for uterine fibroids. Gene expression was determined by RT-PCR. The expression of the VEGF gene was significantly higher in the samples classified as clinical stage 1–2 compared to the control material (p p VEGF gene in the group classified as 1–2 was significantly higher. IGF1 gene expression was significantly lower both in the group of samples classified as clinical stages 1–2 and 3–4 compared to the control group (p H19 gene was significantly lower in the group of samples classified as clinical stage 3–4 compared to the control group (p VEGF, IGF and H19 expression in the pathogenesis of endometriosis.
