Abstract

Laryngeal squamous cell carcinoma (LSCC) is one of the most aggressive cancers that affect the head and neck region. Recent researches have confirmed that long non-coding RNAs (lncRNAs) present an emerging role in diversiform diseases including cancers. Prostate cancer-associated ncRNA transcript 6 (PCAT6) is an oncogene in lung cancer, cervical cancer, colon cancer and gastric cancer, but its role in LSCC is still unknown. In the current study, we attempted to figure out the role of PCAT6 in LSCC. RT-qPCR was to analyze PCAT6 expression in LSCC cells. Functional assays were to uncover the role of PCAT6 in LSCC. Mechanism assays were to explore the regulatory mechanism behind PCAT6 in LSCC. PCAT6 exhibited higher expression in LSCC cells and PCAT6 strengthened cell proliferation and inhibited cell apoptosis. Furthermore, lncRNA PCAT6 modulated notch receptor 3 expression and activated NOTCH signaling pathway via serving as a sponge for miR-4731-5p. Taken together, lncRNA PCAT6 was identified as an oncogene in LSCC, which revealed that PCAT6 might be used as potential therapeutic target for LSCC.
