概括

一种新发现的小细胞肺癌 (SCLC) 亚型是由神经性转录因子ATOH1.1.定义的. 这种亚型表现出细胞存活和前转移功能,表明新的治疗点.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
癌症研究癌症研究

背景情况:

小细胞肺癌 (SCLC) 的分子亚型是由转录因子 (TF) 定义的,如ASCL1,NEUROD1和POU2F3.
之前的研究已经在SCLC循环瘤细胞衍生扩散剂 (CDX) 模型中确定了ATOH1表达亚型.

研究的目的:

在SCLC中验证ATOH1作为定义血统的TF.
研究ATOH1在SCLC细胞存活率和转移中的功能性作用.

主要方法:

在临床前SCLC模型和临床样本中检测ATOH1蛋白.
使用ex vivo培养和体内实验的ATOH1-阳性CDX模型的功能研究.
分析ATOH1在调节神经发生,分化,细胞存活,瘤生长和转移中的作用.

主要成果:

在102个临床SCLC样本中的16个和81个临床前模型中的7个中检测到ATOH1蛋白.
在CDX模型中,ATOH1调节神经发生和分化.
在ex vivo培养物中,ATOH1对于细胞生存至关重要,其枯竭会减缓瘤生长,并减少体内肝转移.

结论:

ATOH1是SCLC的一个子集中的真诚的谱系定义TF.
ATOH1具有细胞存活和转移前的功能.
通过预测性生物标志物准ATOH1驱动的脆弱性,需要对SCLC治疗进行进一步调查.

lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
