摘要
非编码RNA(ncRNA)分子中的单核苷酸多态性(SNP)影响基因和蛋白质表达并产生影响肿瘤疾病风险的遗传变异性。 HOTAIR位于细胞记忆基因程序的核心,代表了长非编码RNA(LncRNA)的原型,因为它具有调节远距离染色体景观的能力。 HOTAIR的异常表达通常与发病机理相关,并且主要与几种人类癌症的转移性进展相关。 不同的多态性,特别是存在于内含子序列中,以及HOTAIR的启动子区域,通常与其异常表达,患者预后和不同肿瘤表型中的癌症易感性相关。 在这个小视图中,我们总结了HOTAIR序列中的主要SNP及其与几种类型实体瘤中癌症风险的关系。

摘要: Single nucleotide polymorphisms (SNPs) in non-coding RNAs (ncRNA) molecules affect gene and protein expression and generate genetic variability influencing the risk of tumor diseases. HOTAIR locates at the heart of the cell memory gene program and represents a prototype of long non coding RNA (LncRNA) due to its capacity to regulate in-trans a distant chromosome landscape.
Aberrant expression of HOTAIR is frequently associated with pathogenesis and mostly with metastatic progression of several human cancers. Different polymorphisms, particularly present in intronic sequences, as well as in promoter regions of HOTAIR, are often associated with its aberrant expression, patient prognosis, and cancer susceptibility in different tumor phenotypes.
In this minireview, we have summarized the main SNPs in HOTAIR sequence and their relation with cancer risk in several types of solid tumors.
