概括

赛尔图因5 (SIRT5) 通过去糖化p53,从而导致状硬化,促进糖尿病脏病中的中细胞增殖和细胞外矩阵积累,导致状硬化.

科学领域:

腎臟病學 (nephrology) 是一種醫學專業.
分子生物学分子生物学
生物化学生物化学

背景情况:

糖尿病病 (DN) 的特点是介质细胞 (MC) 增殖和细胞外矩阵 (ECM) 积累,导致状硬化症.
识别DN中MC增殖的关键调节者对于理解疾病的发病过程至关重要.

研究的目的:

确定导致DN中MC扩散的关键因素 (SIRT5).
探索SIRT5在质硬化症中的作用和机制.

主要方法:

蛋白质组学和发明路径分析 (IPA) 进行SIRT5.5选.
共同免疫沉 (CO-IP) 和质谱测量用于识别SIRT5标.
在MC和小鼠模型中,SIRT5的siRNA介导的淘汰/过度表达.
实时PCR检测p53的目标基因表达.
用于p53化分析的CO-IP.

主要成果:

升高的SIRT5会诱导DN中的MC增殖,ECM积累和质硬化.
在SIRT5脱化p53,降低其转录活性而不会改变蛋白质表达.
抑制p53可以抵消SIRT5对MC增殖和ECM分泌的影响.

结论:

在高葡萄糖条件下的MC中升级的SIRT5通过脱化减少p53的转录活性来促进DN.
这种机制增强了MC的扩散和ECM的分泌,导致了质硬化.
SIRT5是糖尿病脏病的潜在治疗标.

PI3K/mTOR/AKT Signaling Pathway

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...
