Abstract

Background: Oral squamous cell carcinoma (OSCC) at early stages can be misdiagnosed as an oral ulcer (OU) due to similar symptoms, such as chronic and indurated ulcer. LncRNA NCK1-AS1 has been characterized as a key player in cervical cancer, while its role in OSCC is unknown.

Methods: All participants were selected at Jiangxi Province Tumor Hospital from December 2016 to December 2018. Expression levels of NCK1-AS1 and miR-100 in plasma from both OSCC and OU patients were measured by RT-qPCR. Diagnostic analysis was performed through ROC curve. Potential interactions between NCK1-AS1 and miR-100 were detected by cell transfection experiments. Cell invasion and migration were assessed by Transwell assays.

Results: The expression of NCK1-AS1 was upregulated in early-stage OSCC patients but not in OU patients. Upregulation of NCK1-AS1 distinguished OSCC patients from OU patients. The expression of miR-100 was inversely correlated with the expression of NCK1-AS1. Overexpression of NCK1-AS1 was followed by promoted OSCC cell invasion and migration. Overexpression of miR-100 did not affect the expression of NCK1-AS1 but inhibited the role of NCK1-AS1.

Conclusions: Therefore, NCK1-AS1 may promote the metastasis of OSCC by downregulating miR-100.

血浆中LncRNA NCK1-AS1可区分口腔溃疡与早期口腔鳞状细胞癌。

背景:口腔鳞状细胞癌(OSCC)早期由于症状相似，如慢性溃疡和硬化性溃疡，容易被误诊为口腔溃疡(OU)。LncRNA NCK1-AS1被认为在宫颈癌中起关键作用，而其在OSCC中的作用尚不清楚。方法:所有受试者均于2016年12月至2018年12月在江西省肿瘤医院就诊。RT-qPCR检测OSCC和OU患者血浆中NCK1-AS1和miR-100的表达水平。通过ROC曲线进行诊断分析。通过细胞转染实验检测NCK1-AS1与miR-100之间潜在的相互作用。Transwell法检测细胞侵袭和迁移。结果:NCK1-AS1在早期OSCC患者中表达上调，而在OU患者中表达上调。NCK1-AS1的上调可将OSCC患者与OU患者区分开来。miR-100表达与NCK1-AS1表达呈负相关。过表达NCK1-AS1会促进OSCC细胞的侵袭和迁移。过表达miR-100不影响NCK1-AS1的表达，但抑制NCK1-AS1的作用。结论:NCK1-AS1可能通过下调miR-100促进OSCC转移。
