endometrial cancer is the most common gynecological malignancy, affecting up to 3% of women at some point during their lifetime (Morice et al., 2016; Li and Wang, 2021). Based on the pathogenesis and biological behavioral characteristics, endometrial cancer can be divided into estrogen-dependent (I) and non-estrogen-dependent (II) types (Ulrich, 2011). Type I accounts for approximately 80% of cases, of which the majority are endometrioid carcinomas, and the remaining are mucinous adenocarcinomas (Setiawan et al., 2013). It is generally recognized that long-term stimulation by high estrogen levels with the lack of progesterone antagonism is the most important risk factor; meanwhile, there is no definite conclusion on the specific pathogenesis. The incidence of endometrial cancer has been on the rise during the past two decades (Constantine et al., 2019; Gao et al., 2022; Luo et al., 2022). Moreover, the development of assisted reproductive technology and antiprogestin therapy following breast cancer surgery has elevated the risk of developing type I endometrial cancer to a certain extent (Vassard et al., 2019). Therefore, investigating the influence of estrogen in type I endometrial cancer may provide novel concepts for risk assessment and adjuvant therapy, and at the same time, provide a basis for research on new drugs to treat endometrial cancer.

概要: 子宫内膜癌是最常见的子宫癌类型,占子宫癌病例的90%。本文通过临床研究,检测子宫内膜癌患者标本中雌激素受体(ER)和DNA复制ATP依赖性解旋酶/核酸酶(DNA2)的表达,并分析两者之间的关系。通过细胞培养实验研究ER调控DNA2表达的机制,证实其与PI3K-AKT通路有关。研究还发现,使用短发夹RNA(shRNA)特异性靶向降低Ishikawa中DNA2的表达,会导致细胞增殖和克隆形成能力降低。总的来说,本研究证实了DNA2作为治疗靶点的可行性,并证明抑制DNA2可使Ishikawa对喜树碱(CPT)化疗增敏。我们的发现为DNA2的潜在机制提供了新的见解,这将有助于开发与子宫内膜癌诊断和治疗相关的新方法。
