Head and neck squamous cell carcinoma (HNSCC) is the sixth most prevalent malignancy worldwide. Accumulating evidence suggests that persistent HPV infection is closely related to a subset of HNSCC types, and the incidence of human papillomavirus (HPV)-positive HNSCC has been annually increasing in recent decades. Although the carcinogenesis of HPV-positive HNSCC has not been completely elucidated, it has been well confirmed that E6 and E7, the main viral oncoproteins are responsible for the maintenance of malignant transformation, promotion of cell proliferation, and increase in tumor invasion. Moreover, compared with HPV-negative HNSCC, HPV-positive HNSCC shows some special clinical-pathological features, which are possibly related to HPV infection and their specific regulatory mechanisms. Non-coding RNA (ncRNA) is a class of RNA lacking the protein-coding function and playing a critical regulatory role multiple complex molecular mechanisms. NcRNA is an important regulatory pattern of epigenetic modification, which can exert significant effects on HPV-induced tumorigenesis and progression by deregulating downstream genes. However, the knowledge of ncRNAs is still limited, hence, a better understanding of ncRNAs could provide some insights for exploring the carcinogenesis mechanism and identifying valuable biomarkers in HPV-positive HNSCC. Therefore, in this review, we mainly focused on the expression profile of ncRNAs (including lncRNA, miRNA, and circRNA) and explored their regulatory role in HPV-positive HNSCC, aiming to clarify the regulatory mechanism of ncRNAs and identify valuable biomarkers for HPV-positive HNSCC.
头颈部鳞状细胞癌(HNSCC)是全球第六大常见恶性肿瘤。越来越多的证据表明,持续性人乳头瘤病毒(HPV)感染与一部分HNSCC类型密切相关,并且近几十年来HPV阳性HNSCC的发病率一直在逐年上升。尽管HPV阳性HNSCC的致癌机制尚未完全阐明,但已充分证实,主要病毒癌蛋白E6和E7负责维持恶性转化、促进细胞增殖以及增加肿瘤侵袭。此外,与HPV阴性HNSCC相比,HPV阳性HNSCC表现出一些特殊的临床病理特征,这可能与HPV感染及其特定调节机制有关。非编码RNA(ncRNA)是一类缺乏蛋白质编码功能且通过多种复杂分子机制发挥关键调节作用的RNA。NcRNA是表观遗传修饰的一种重要调节模式,它可以通过调控下游基因对HPV诱导的肿瘤发生和进展产生显著影响。然而,目前对ncRNAs的了解仍然有限,因此,更好地了解ncRNAs可为探索HPV阳性HNSCC的致癌机制和识别有价值的生物标志物提供一些见解。因此,在本综述中,我们主要关注ncRNAs(包括lncRNA、miRNA和circRNA)的表达谱,并探讨它们在HPV阳性HNSCC中的调节作用,旨在阐明ncRNAs的调节机制并为HPV阳性HNSCC识别有价值的生物标志物。
