神经科学是一个神经科学.
发展生物学发展生物学
眼科医生眼科眼科

背景情况:

蛋白激酶N1 (PKN1) 作为转录因子神经分化-2 (NeuroD2) 的守门员.
神经D2对于亚马克林细胞 (AC) 和视网膜质细胞 (RGC) 的形成至关重要.

研究的目的:

通过检查野生型 (WT) 和Pkn1淘汰小鼠的NeuroD2表达来研究PKN1在视网膜发育中的作用.
具体分析对AC和RGC种群的影响.

主要方法:

在WT和Pkn1淘汰赛小鼠的产后视网膜中分析NeuroD2表达.
免疫组织化学测量特定细胞类型,包括AC和RGC.
视网膜结构和视神经指导的评估.

主要成果:

PKN1在视网膜中被广泛表达,在Pkn1淘汰网膜中没有明显的结构差异.
Pkn1淘汰网膜表现出较高的NeuroD2水平和更多的AC.
在Pkn1淘汰赛视网膜中观察到SMI-32+α-RGCs的特定减少,而不会影响其他RGC亚型或轴突指导.

The Retinoblastoma Gene

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
