概括
从白色脂肪组织 (WAT) 中的microRNAs (miRNAs) 的早期变化可以预测2型糖尿病 (T2D) 的风险. 女性的miR-335-5p变化与代谢变化和T2D发展有关.
科学领域:
- 内分泌学和新陈代谢学
- 分子生物学分子生物学
- 遗传学 遗传学是一种遗传学.
背景情况:
- 白色脂肪组织 (WAT) 功能障碍和改变的微RNA (miRNA) 表达与2型糖尿病 (T2D) 风险有关.
- 关于预测T2D的WAT衍生的miRNAs早期变化的证据有限.
- 这项研究调查了WAT早期miRNome变化作为潜在的T2D生物标志物.
研究的目的:
- 在小鼠和人类中早期识别白色脂肪组织 (WAT) 中的miRNome变化,这些变化是2型糖尿病 (T2D) 的预后.
- 在T2D的背景下探索miRNA表达,DNA甲基化和代谢表型之间的联系.
- 调查印制miRNAs在T2D发展中的作用.
主要方法:
- 进行了多组体分析 (转录组,miRNome,甲基组,蛋白质组) 对来自抗糖尿病和易患糖尿病的小鼠的淋巴腺WAT进行了分析.
- 代谢表型与脂肪组织miRNA表达和DNA甲基化在T2D不一致的单胞胎双胞胎对中相关.
- 在TÜF研究中,分析了高风险女性的血miRNA水平.
主要成果:
- 易患糖尿病的小鼠显示胰岛素敏感性降低,WAT.中大约有200个差异表达的miRNA.
- 综合分析显示,有227种蛋白质参与氨基酸代谢,炎症和胰岛素抵抗.
- 包括miR-335在内的20多种差异表达的miRNA位于印记区域,并在双胞胎中显示出类似的变化;在高危女性中,miR-335-5p的血水平与空腹血糖呈负相关性.
结论:
- 从WAT衍生的miRNAs,如miR-335-5p的早期变化可能会导致与T2D风险相关的全身代谢变化.
- 在WAT中印制的miRNAs可能通过DNA甲基化进行调节,并在T2D中表现出改变的表达.
- miR-335-5p作为T2D风险的潜在早期生物标志物,特别是在女性中.

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

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...
