摘要

心肌梗死相关转录本(MIAT)是一种核长链非编码RNA (LncRNA),具有四种不同的剪接变体。MIAT失调与癌变有关,主要作为癌基因调节细胞生长、侵袭和转移。本研究的目的是探讨mat在T细胞和慢性髓性白血病细胞存活调控中的作用。为此,在白血病细胞系中使用MIAT特异性sirna沉默MIAT,然后进行功能分析。本研究还旨在探讨MIAT沉默对癌症相关核心基因表达的影响。功能研究和基因表达测定证实,MIAT敲低不仅影响白血病细胞的短期和长期存活及凋亡,还在癌症相关关键基因c-MYC和HIF-1A的改变中起关键作用。我们的观察结果表明,MIAT可以作为一种致癌基因,它不仅有潜力作为白血病的可靠生物标志物,而且还可用于预后和治疗目的。

Investigation into the Role of Long-Non-Coding RNA MIAT in Leukemia.

Myocardial Infarction Associated Transcript (MIAT) is a nuclear long non-coding RNA (LncRNA) with four different splicing variants. MIAT dysregulation is associated with carcinogenesis, mainly acting as an oncogene regulating cellular growth, invasion, and metastasis. The aim of the current study is to investigate the role of MIAT in the regulation of T and chronic myeloid leukemic cell survival. To this end, MIAT was silenced using MIAT-specific siRNAs in leukemic cell lines, and functional assays were performed thereafter. This investigation also aims to investigate the effects of MIAT silencing on the expression of core genes involved in cancer. Functional studies and gene expression determination confirm that MIAT knockdown not only affects short- and long-term survival and the apoptosis of leukemic cells but also plays a pivotal role in the alteration of key genes involved in cancer, including c-MYC and HIF-1A. Our observations suggest that MIAT could act as an oncogene and it has the potential to be used not only as a reliable biomarker for leukemia, but also be employed for prognostic and therapeutic purposes.
