Abstract:
Oral squamous cell carcinoma (OSCC) is a common and aggressively malignant tumor of the head and neck region. Long non-coding RNAs (lncRNAs) are important regulatory molecules in many types of cancer. However, there are limited studies on the role of lncRNAs in OSCC. In this study, we identified that lncRNA P4713 was one of the most up-regulated lncRNAs in OSCC by exploring the expression profile of lncRNAs/mRNAs in four pairs of OSCC samples and adjacent non-cancer tissues. In addition, silencing of P4713 inhibited OSCC proliferation, migration, and invasion in vitro. Furthermore, through bioinformatics analysis and functional experiments, we found that decreased P4713 expression affected the expression and phosphorylation of Janus Kinase (JAK) 2 and signal transducer and activator of transcription (STAT) 3. Taken together, the results suggest that P4713 contributes to OSCC cell proliferation, migration, and invasion by activating the JAK/STAT3 pathway. Accordingly, this molecule could be a potential biomarker and therapeutic target in the treatment of OSCC.
