Ovarian cancer (OC) has the highest mortality rate of all gynecological malignancies. Moreover, at the time of the first clinical manifestation, most patients have an advanced stage of the disease. Our study examined differences in mRNA levels of hypoxia-inducible factor 1-alpha (); endothelial PAS domain protein 1, also known as hypoxia-inducible factor 2-alpha (); and vascular endothelial growth factor A () between cancerous tissue, benign hyperplastic changes in the ovary, and normal tissue. Our cohorts consisted of 52 patients diagnosed with OC ( = 55), benign non-cancerous changes ( = 21), and normal tissue samples ( = 38). The mRNA expression level was evaluated using RT-qPCR. We found that gene expression changes were visible not only in the case-control study, but also along with changes in severity. Additionally, the gene expression was differentiated in age, BMI, menopausal status, and the number of comorbidy-related groups. Furthermore, our findings demonstrate that analyzing the correlation between genes is essential. In a case-to-case and case-to-control study, we observed disturbances in the expression levels of interdependent genes. Our findings suggest that mutual association in the expression of both and with has prognostic importance for patients with OC. Our observations may help identify patients for clinical trials aimed at inhibiting the hypoxia-induced neovascularization-dependent pathways.
卵巢癌(OC)在所有妇科恶性肿瘤中死亡率最高。此外,在首次临床表现时,大多数患者已处于疾病晚期。我们的研究检测了缺氧诱导因子1α(HIF-1α)、内皮PAS结构域蛋白1(也称为缺氧诱导因子2α,HIF-2α)和血管内皮生长因子A(VEGF-A)在癌组织、卵巢良性增生性改变组织和正常组织之间的mRNA水平差异。我们的队列包括52例诊断为OC的患者(n = 55)、良性非癌性改变患者(n = 21)和正常组织样本(n = 38)。使用逆转录定量聚合酶链反应(RT-qPCR)评估mRNA表达水平。我们发现,基因表达变化不仅在病例对照研究中可见,而且随着疾病严重程度的变化而变化。此外,基因表达在年龄、体重指数、绝经状态和合并症相关组数量方面存在差异。此外,我们的研究结果表明,分析基因之间的相关性至关重要。在个案和病例对照研究中,我们观察到相互依赖基因表达水平的紊乱。我们的研究结果表明,HIF-1α和HIF-2α与VEGF-A表达之间的相互关联对OC患者具有预后重要性。我们的观察结果可能有助于确定适合进行旨在抑制缺氧诱导的新生血管依赖途径的临床试验的患者。
