概括
孕期糖尿病 (GDM) 和肥胖会改变胎盘结构,体积和血管化. 表观遗传变化,特别是DNA甲基化,与这些胎盘功能障碍有关.
科学领域:
- 产科和妇科 产科和妇科
- 生殖生物学 生殖生物学
- 代谢障碍 代谢障碍 代谢障碍
背景情况:
- 肥胖和妊娠期糖尿病 (GDM) 是影响母亲和胎儿健康的流行代谢疾病.
- 这些情况经常与胎盘功能障碍和结构变化有关.
- 主要的胎盘功能调节者包括阿佩林受体 (APLNR),血管内皮生长因子 (VEGF),丁和DNA甲基化.
研究的目的:
- 调查肥胖和GDM的母亲的胎盘体积和血管化.
- 在这些人群中确定胎盘APLNR,VEGF,瘦素和DNA甲基化中的变化.
主要方法:
- 使用3D超声波对体积和血管化进行分析的人类胎盘 (n = 48).
- 胎盘APLNR表达通过RT-PCR量化.
- 使用ELISA测量了瘦素和VEGF度.
- 全球DNA甲基化被评估使用色度测定试验.
主要成果:
- 与对照组相比,肥胖和GDM病例的胎盘体积增加.
- 在GDM和肥胖的胎盘中,血管化指数显著降低.
- 在肥胖和GDM胎盘中,APLNR,瘦素和VEGF水平下降,GDM具有更明显的效果.
- 在这两组中,DNA甲基化升高,在GDM中更为如此.
结论:
- 这项研究揭示了肥胖和GDM的胎盘结构变化.
- 这两种情况都影响着胎盘体积和血管性,减少了勒和VEGF,可能由表观遗传因素介导.
- 结果表明,在GDM和肥胖症中异常的胎盘功能是潜在的治疗点.

Pathophysiology of Diabetes
3.1K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes Mellitus: Type 2 and Gestational
4.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
