Head and neck squamous cell carcinomas (HNSCC) is one of the most prevalent type of cancer known in Indian population. Studies are needed to identify the early biomarkers for HNSCC. MicroRNAs (miRNAs) are non-coding RNA molecules, expression of which can be used as biomarker for early diagnosis of HNSCC. For miRNA profiling total RNA, which also contained small RNAs were isolated from ten HNSCC tissue samples and adjacent control. Purity and concentration of eluted RNA was assessed using the NanoDrop1000® spectrophotometer, Reverse Transcription reaction was carried out with megaplex RT primers of pool A and pool B and the expression of selected miRNAs (miR-143/145 and miR-18a/b) was measured using TaqMan primers specific for mature miRNAs. Our study showed dramatic downregulation in expression of two miRNAs, miR-18b and miR-145 in blood samples of HNSCC patients, which are inhibitor of tumorigenesis and can be targeted as biomarker of HNSCC pathogenesis therefore developing avenues for miRNA role in prognosis and therapeutics.

头颈部鳞状细胞癌(HNSCC)是印度人群中已知的最常见癌症类型之一。需要开展研究以确定HNSCC的早期生物标志物。微小RNA(miRNA)是非编码RNA分子,其表达可作为HNSCC早期诊断的生物标志物。为了进行miRNA谱分析,从10个HNSCC组织样本和相邻对照中分离出总RNA,其中也包含小RNA。使用NanoDrop1000®分光光度计评估洗脱RNA的纯度和浓度,用A池和B池的多重逆转录引物进行逆转录反应,并使用针对成熟miRNA的TaqMan引物测量所选miRNA(miR-143/145和miR-18a/b)的表达。我们的研究表明,HNSCC患者血液样本中两种miRNA,即miR-18b和miR-145的表达显著下调,它们是肿瘤发生的抑制剂,可作为HNSCC发病机制的生物标志物,因此为miRNA在预后和治疗中的作用开辟了途径。
