- -葡萄糖共运输体2 (SGLT2) 在功能中至关重要,其抑制剂用于糖尿病,心力衰竭和病.
- 在乳头细胞癌 (pRCC) 中SGLT2的作用仍然未被探索.
研究的目的:
- 为了研究SGLT2在pRCC中的表达.
- 分析SGLT2表达和临床分子特征之间的相关性.
- 为了确定SGLT2在pRCC患者存活率中的预后意义.
主要方法:

- 在pRCC瘤中分析了SGLT2mRNA表达z-scores,与正常样本相比.
- 相关的SGLT2表达与基因表达,瘤突变负担,动脉化和整体存活率 (OS).
主要成果:
- 在273名pRCC患者中,66%的SGLT2表达低.
- 在SGLT2和像IRX5,FOXC1和HIF-2α这样的基因之间观察到高相关性.
- 在未经改变的SGLT2表达组中,SETD2的改变更频繁.

Glucose Transporters
22.3K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Glucose Absorption Into the Small Intestine
31.2K
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and...

Transducer Mechanism: Enzyme-Linked Receptors
2.3K
Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
