概括

用网膜酸 (RA) 和双乙烯循环AMP治疗的甲状腺癌细胞分化为神经丝表达细胞. 进一步添加神经生长因子 (NGF) 诱导上腺特征,这表明F9细胞可以模拟上腺神经元发育.

科学领域:

发育生物学是发展生物学.
神经科学是一个神经科学.
细胞生物学细胞生物学

背景情况:

甲状腺癌细胞作为脊椎动物分化和发育的模型.
网红素酸 (RA) 和双基循环AMP在一些胚胎癌 (EC) 细胞系中诱导神经分化.
短期的RA和 dibutyryl循环AMP治疗增加了F9细胞中的乙胆酶 (AChE) 活性.

研究的目的:

为了研究F9甲状腺癌细胞的长期分化.
为了确定F9细胞是否可以分化为上腺神经元类细胞.

主要方法:

长期培养的F9细胞与RA和 dibutyryl循环AMP.
使用特定抗体检测神经丝表达的免疫光学.
添加神经生长因子 (NGF) 并评估氨酸氧酶和Leu-enkephalin类的免疫活性.

主要成果:

长期培养诱导了F9细胞中的神经丝表达.
与NGF同时治疗导致细胞表达氨酸氧酶,这是一种上腺神经元的标记物.
还观察到类似于leu-enkephalin的的免疫活性.

结论:

可以诱导F9癌细胞分化为具有上腺神经元特征的细胞.
这为研究上腺神经元分化提供了一个模型.

Enzyme-linked Receptors

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
