Long non-coding RNAs (LncRNAs), are significant in a number of biological stages and illnesses. The myocardial infarction associated transcript (MIAT) serves a function in numerous types of illness and physiological and pathological processes, including paranoid schizophrenia, diabetic retinopathy, myocardial infarction and neuroendocrine prostate cancer. However, the function of the lncRNA MIAT in the development of osteosarcoma is unknown. It has been identified that during the development of osteosarcoma, MIAT is upregulated in tumor tissues compared to adjacent non-tumor tissues. The spreading and proliferation of osteosarcoma cells was reduced by MIAT knockdown. These findings indicate that MIAT functions by competing with critical RNAs to target miR-150-5p and activate zinc finger E-box binding homeobox 1 to modulate the function of osteosarcoma cells. Together, the present findings may contribute to the understanding of the pathogenesis of osteosarcoma.
长链非编码RNA(LncRNAs)在许多生物学阶段和疾病中具有重要意义。心肌梗死相关转录本(MIAT)在多种疾病以及生理和病理过程中发挥作用,包括偏执型精神分裂症、糖尿病视网膜病变、心肌梗死和神经内分泌前列腺癌。然而,lncRNA MIAT在骨肉瘤发生发展中的作用尚不清楚。现已确定,在骨肉瘤发生过程中,与相邻非肿瘤组织相比,MIAT在肿瘤组织中表达上调。敲低MIAT可减少骨肉瘤细胞的扩散和增殖。这些发现表明,MIAT通过与关键RNA竞争来靶向miR-150-5p并激活锌指E盒结合同源框1,从而调节骨肉瘤细胞的功能。总之,目前的研究结果可能有助于理解骨肉瘤的发病机制。
