Long Noncoding RNA LOC441178 Reduces the Invasion and Migration of Squamous Carcinoma Cells by Targeting ROCK1
BioMed Research International
In recent years, long noncoding RNAs (lncRNAs) have been reported to have significant regulating effect in human cancer development. Previous studies suggested that dysregulation of lncRNA 441178 (LOC441178) is possibly associated with oral squamous cell carcinoma (OSCC). The postoperative survival time was significantly prolonged in the high-grade OSCC patients with high LOC441178 expression compared with those with low LOC441178 expression, which indicated that LOC441178 may act as a
... y act as a prognostic marker and as a potential tumor suppressor for OSCC. However, the biological molecular mechanisms behind these phenomena remain almost unknown. Here, our studies revealed that LOC441178 suppressed the invasion and migration of squamous carcinoma cells (SCCs). Furthermore, we found that rho-associated, coiled-coil-containing protein kinase 1 (ROCK1) is one of the functionally relevant targets of LOC441178 in squamous cells, which is negatively correlated with LOC441178 in tumor tissues from OSCC patients. In conclusion, our findings demonstrated the inhibition effect of LOC441178 on tumor in OSCC and might have potential implications for OSCC gene therapy. In conclusion, these results suggest that LOC441178 could represent a prognostic indicator for OSCC and be a new target for the diagnosis and treatment of OSCC.
