自然反义转录子(natural antisense transcripts,NAT)在生物界中广泛存在,且发挥着重要的基因表达调控作用。NAT表达水平的高、低可调控多种生物的多种重要的生理活动,尤为重要的是,目前已经证实aHIF、gfg-1、p15AS、rTSα等NAT分子能直接作用于多种肿瘤相关的关键因子,其异常表达与多种肿瘤的发生、发展有密切关系。
Natural antisense transcripts (NATs) are widespread in the biological world and play an important regulatory role in gene expression. NAT high and low expression can regulate a variety of important biological activities of a variety of organisms, it is especially important that it has been confirmed that aHIF, gfg-1, p15AS, rTSα and other NAT molecules can directly affect a variety of tumor-related key Factors, abnormal expression and a variety of tumor occurrence and development are closely related.
