Long non-coding RNA (lncRNA) has emerged as a new avenue of interest due to its various biological functions in cancer. Abnormal expression of lncRNA has been reported in other malignancies but has been understudied in head and neck squamous cell carcinoma (HNSCC).
The lncRNA expression was interrogated via quantitative real-time polymerase chain reaction (qRT-PCR) array for 19 human papillomavirus (HPV)-negative HNSCC tumor-normal pairs. The Cancer Genome Atlas (TCGA) was used to validate these results. The association between differentially expressed lncRNA and survival outcomes was analyzed.
Differential expression was validated for 5 lncRNA (SPRY4-IT1, HEIH, LUCAT1, LINC00152, and HAND2-AS1). There was also an inverse association between MEG3 expression (not significantly differentially expressed in TCGA tumors but highly variable expression) and 3-year recurrence-free survival (RFS).
We identified and validated differential expression of 5 lncRNA in HPV-negative HNSCC. Low MEG3 expression was associated with favorable 3-year RFS, although the significance of this finding remains unclear.
长链非编码 RNA(lncRNA)因其在癌症中的各种生物学功能而成为一个新的研究热点。lncRNA 的异常表达已在其他恶性肿瘤中被报道,但在头颈部鳞状细胞癌(HNSCC)中研究较少。
通过定量实时聚合酶链反应(qRT-PCR)阵列对 19 对 HPV 阴性 HNSCC 肿瘤-正常对进行 lncRNA 表达检测。使用癌症基因组图谱(TCGA)验证这些结果。分析差异表达 lncRNA 与生存结局的相关性。
验证了 5 个 lncRNA(SPRY4-IT1、HEIH、LUCAT1、LINC00152 和 HAND2-AS1)的差异表达。MEG3 表达(在 TCGA 肿瘤中差异不显著,但表达高度可变)与 3 年无复发生存率(RFS)呈负相关。
我们鉴定并验证了 HPV 阴性 HNSCC 中 5 个 lncRNA 的差异表达。低 MEG3 表达与 3 年 RFS 良好相关,尽管这一发现的意义尚不清楚。
