- 2型糖尿病 (T2D) 与前列腺癌风险之间的联系是复杂的,与T2D相关的遗传因素的预后影响尚不清楚.
研究的目的:
- 调查T2D易感性单核酸多形态 (SNPs) 和BCR风险之间的关系,在男性进行激进前列腺切除术 (RP).
- 探索SNP在前列腺癌进展和复发中的功能作用.
主要方法:
- 在644名台湾前列腺癌患者中分析了113个与T2D相关的SNP,这些患者接受了RP治疗.
- 考克斯回归模型用于评估SNP与BCR的关联,并根据临床因素进行调整.
- 功能分析包括基因表达 (C2依赖域含4A - C2CD4A),途径分析 (GSEA,GSVA) 和与临床病理特征的相关性.
主要成果:
- 在C2CD4A中与T2D相关的SNPrs4502156独立地与BCR风险降低相关 (HR=0.80,p=0.035).

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

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...

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...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
