Abstract Background Mounting studies demonstrate long non-coding RNAs (lncRNAs) play an important role in tumor progression. However, the potential biological functions and clinical importance of linc01234 in oral squamous cell carcinoma (OSCC) still remain unclear. Methods Two OSCC cells were transfected with siRNAs targeting linc01234, and RT-qPCR, CCK-8, EDU, wound healing and Transwell and western blot assays were performed to analyze the effect of linc01234 on cell proliferation, migration and invasion. Bioinformatic analysis, luciferase assays and RT-qPCR identified a competitive endogenous RNAs (ceRNAs) among linc01234, miR-433-3p and PAK4. Results We found that linc01234 was significantly upregulated in OSCC tissues and cell lines and positively associated with T stage, lymphnode metastasis, differentiation. Kaplan-Meier analysis of OSCC reveals a positive correlation between linc01234 and the overall survival. Following the linc01234 deletion, the cell proliferation and metastasis abilities in CAL27 and SCC25 cells were found to be extremely reduced. Mechanism studies indicated that linc01234 located in cytoplasm and shared microRNA (miRNA) response elements with miR-433-3p. Luciferase assays indicated that miR-433-3p bind to the 3′-UTR of PAK4. Conclusions Our results indicated that linc01234 functioned as an oncogene in OSCC and might be a potential therapeutic target for OSCC.

Abstract Background: Mounting studies demonstrate long non-coding RNA s ( lncRNAs ) play an important role in tumor progression. However, the potential biological functions and clinical importance of Linc01234 in oral squamous cell carcinoma ( OSCC ) still remain unclear. Methods: We evaluated the expression profile and prognostic values of Linc01234 in OSCC tissues via RT-qPCR. Then, functional experiments in vitro were performed to investigate the effects of Linc01234 on tumor growth, migration and invasion in OSCC. Mechanistically, RT-qPCR, bioinformatic analysis and dual luciferase reporter assays were performed to identify a competitive endogenous RNA s ( ceRNA s) among Linc01234, miR-433-3p and PAK4. Results: We found that Linc01234 was evidently upregulated in OSCC tissues and cell lines, and its level was positively associated with T stage, lymphnode metastasis, differentiation and poor prognosis of patients with OSCC. Our results found that Linc01234 inhibited cell proliferation and metastasis abilities in CAL27 and SCC25 cells following its deletion. Mechanistic analysis indicated that Linc01234 may act as a ceRNA (competing endogenous RNA) of miR-433-3p to relieve the repressive effect of miR-433-3p on its target PAK4. Conclusions: Our results indicated that Linc01234 promotes OSCC progression through Linc01234/miR-433/PAK4 axis and might be a potential therapeutic target for OSCC.

Oral squamous cell carcinoma (OSCC) had the poor prognosis. miR-155 was involved in some diseases. However, whether BMSCs with high expression miR-155 affect the proliferation and metastasis of OSCC is unclear. Our study aims to assess BMSCs’ effect on OSCC cells. miR-155 level in OSCC tumor tissues was analyzed. BMSCs were transfected with miR-155 followed by analysis of cell proliferation by MTT assay, cell apoptosis and migration, and MMP-9 level by ELISA and PTEN12 level. In the tumor tissue, miR-155 level was significantly increased (P <0.05). Co-culture of BMSCs with high expression miR-155 with OSCC cells could significantly promote OSCC cell proliferation and reduced cell apoptotic activity, increased cell migration and MMP-9 secretion as well as downregualted PTEN12 expression (P <0.05). In conclusion, miR-155 was increased in the OSCC patients and BMSCs of high expression miR-155 could promote the proliferation and metastasis of OSCC by regulating PTEN12.
