Although microRNAs (miRNAs or miRs) are able to function as oncogenes or tumor suppressors, the role of miR-326 in regulating human cervical cancer cells remains unclear. In the present study, the expression of miR-326 was identified to be downregulated in cervical cancer cell lines and primary tumor samples, and the overexpression of miR-326 decreased cell proliferation, migration and invasion in cervical cell lines. Bioinformatics prediction and experimental validation results revealed that the function of miR-326 was achieved by targeting and repressing ETS domain-containing protein Elk-1 () expression. was targeted directly by miR-326, which was downregulated in human cervical cancer tissues compared with that in adjacent normal tissues. The results of the present study suggest that miR-326, a potential tumor suppressor, may be used in the treatment of cervical cancer.
尽管微小RNA(miRNA或miR)能够作为癌基因或肿瘤抑制因子发挥作用,但miR-326在调控人宫颈癌细胞中的作用仍不清楚。在本研究中,已确定miR-326在宫颈癌细胞系和原发性肿瘤样本中的表达下调,并且miR-326的过表达降低了宫颈细胞系中的细胞增殖、迁移和侵袭。生物信息学预测和实验验证结果表明,miR-326的功能是通过靶向并抑制含ETS结构域蛋白Elk-1()的表达来实现的。被miR-326直接靶向,与相邻正常组织相比,其在人宫颈癌组织中表达下调。本研究结果表明,miR-326作为一种潜在的肿瘤抑制因子,可能用于宫颈癌的治疗。
