概括
研究人员在头部和部状细胞癌 (HNSCC) 中发现了微抑制行为细胞骨 (MIAC). 较低的MIAC表达与低生存率相关,并影响其他癌症,这表明它在瘤发生中起作用.
科学领域:
- 分子生物学
- 癌症学
- 基因组学
背景情况:
- 由非编码RNA编码的微被越来越多地识别.
- 此前在头部和部状细胞癌 (HNSCC) 中没有报告过微.
研究的目的:
- 发现和描述HNSCC中的新型微.
- 研究MIAC在HNSCC进展和其他癌症中的作用.
主要方法:
- 癌症基因组图谱 (TCGA) 数据库的分析 (n=500).
- 对新鲜临床HNSCC样本 (n=94) 和组织微阵列 (n=60) 的分析.
- 在32个TCGA癌症队列中对9657个人体组织进行RNA测序分析.
主要成果:
- 发现并描述了一种新型人体内源性,即抑制动因细胞骨的微 (MIAC).
- 较低的MIAC表达与HNSCC患者的整体存活率较低有关.
- MIAC表达与其他5种瘤类型的进展有显著关联.
结论:
- 通过调节Septin 2 (SEPT2) / Integrin Beta 4 (ITGB4),MIAC直接与Aquaporin 2 (AQP2) 相互作用以抑制行为细胞骨.
- 在HNSCC中抑制瘤生长和转移.
- 在HNSCC瘤发生过程中,MIAC起着至关重要的作用,对其他癌症有影响.

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
