概括
MAPT反感1 (MAPT-AS1) 长非编码RNA不调节人类神经元中的Tau表达. 因此,MAPT-AS1不是降低阿尔茨海默氏症和其他病症的可行的治疗标.
科学领域:
- 神经科学是一个神经科学.
- 分子生物学分子生物学
- 遗传学 是一个遗传学.
背景情况:
- 陶蛋白,由MAPT基因编码,聚合在神经退行性疾病如阿尔茨海默氏症.
- 了解调节对于开发有效的阿尔茨海默病 (AD) 治疗至关重要.
- 自然反感转录 (NAT) 是长的非编码RNA (lncRNA),可以调节基因表达.
研究的目的:
- 研究MAPT反感1 (MAPT-AS1) lncRNA在调节MAPT基因表达中的作用.
- 确定MAPT-AS1是否是一种潜在的治疗点,用于降低陶氏度.
主要方法:
- 在人类神经母细胞瘤细胞系和诱导多能干细胞 (iPSC) 衍生神经元中调节了MAPT-AS1的表达.
- 在MAPT-AS1调节后,分析了MAPT mRNA和Tau蛋白水平.
主要成果:
- 调节MAPT-AS1表达并没有改变MAPT mRNA或Tau蛋白水平.
- 与之前的报道相反,MAPT-AS1在体外没有显示出Tau表达的调节作用.
结论:
- MAPT-AS1似乎没有调节人类神经元中的Tau表达.
- MAPT-AS1不太可能成为降低阿尔茨海默病或其他病的治疗点.

Microtubule Associated Proteins (MAPs)
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...
Microtubule Instability
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated assembly and...
