概括

催产素 (OT) 会影响卡韦林和聚合酶转录释放因子 (PTRF) 的表达. 在前列腺癌细胞中,OT影响了催产素受体 (OTR) 运动,可能导致扩散.

科学领域:

细胞生物学细胞生物学
分子瘤学分子瘤学
前列腺癌研究前列腺癌研究.

背景情况:

正常前列腺细胞中的催产素 (OT) 受体位于洞穴内.
前列腺癌的进展包括聚合酶转录释放因子 (PTRF) 的降低,洞穴的丧失和受体转位.
这项研究研究了OT对洞穴蛋白和催产素受体 (OTR) 动态的影响.

研究的目的:

研究OT如何影响参与洞穴形成的蛋白质.
确定OT治疗对活细胞中催产素受体 (OTR) 运动的影响.
阐明与OTR和洞穴蛋白相关的细胞增殖机制.

主要方法:

使用了正常的人类前列腺上皮细胞 (PrEC) 和与雄激素无关的PC3癌细胞.
在细胞系和人类前列腺组织中评估了OTR,caveolin和PTRF的表达.
使用TIRF显微镜实时观察OTR转位.

主要成果:

PTRF表达与前列腺癌恶性病变相反相关.
OT治疗降低了Caveolin-1的调节,并影响了PrEC和PC3细胞中的Caveolin-2表达.
OT 降低了 PrEC 细胞中的 PTRF; OTR 在正常细胞中转移到洞穴内,但在恶性细胞中自由移动.

结论:

OT调节了卡韦林和PTRF的表达.
在恶性前列腺细胞中,OTR运动不受约束,可能促进信号通路.
研究结果表明,在前列腺癌中,OTR,洞穴蛋白和增强的细胞增殖之间存在联系机制.

Internal Receptors

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Intracellular Hormone Receptors

Intracellular Hormone Receptors

Lipid-soluble hormones diffuse across the plasma and nuclear membrane of target cells to bind to their specific intracellular receptors. These receptors act as transcription factors that regulate gene expression and protein synthesis in the target cell

Transducer Mechanism: Enzyme-Linked Receptors

Transducer Mechanism: Enzyme-Linked Receptors

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.
Major types that are helpful drug targets include:
