Background/Aims: Cervical cancer, which is one of the most aggressive cancers affecting females, has high rates of recurrence and mortality. Small nucleolar RNA host gene 12 (SNHG12) is known to promote the progression of several cancers; however, its exact effects and molecular mechanisms in cervical cancer remain unknown. Methods: Real-time quantitative PCR was used to determine the expression level of SNHG12 in cervical cancer tissues and cell lines. Loss-of-function assays were performed to examine the effect of SNHG12 on the proliferation, apoptosis, migration and invasion of cervical cancer cells in vitro and tumor growth in vivo. Luciferase experiments were employed to explore the interactions between SNHG12 and miR-424-5p. Results: SNHG12 was found to be abnormally elevated in human cervical cancer tissues compared with paired adjacent normal tissues. Moreover, high SNHG12 expression in tumor tissues was significantly correlated with vascular involvement, lymph node metastasis, advanced FIGO stage and poor prognosis. Furthermore, the knockdown of SNHG12 was found to inhibit proliferation, migration and invasion of cervical cancer cells in vitro, and silencing SNHG12 was shown to suppress tumor growth in a nude mouse model. Mechanistic studies showed that SNHG12 functioned as an endogenous sponge for miR-424-5p, thereby downregulating the expression of miR-424-5p in cervical cancer. Furthermore, the inhibition of miR-424-5p in SNHG12-depleted cells partially reversed the effects on cervical cancer cell apoptosis, adhesion and invasion. Conclusion: In summary, our findings suggest that the tumor-promoting role of SNHG12 is to function as a molecular sponge, which negatively regulates miR-424-5p. These findings may provide a potent therapeutic target for cervical cancer.

Small nucleolar RNA host gene 14 (SNHG14) is a long non-coding RNA found to be overexpressed in various types of cancers. Moreover, the expression level of SNHG14 was closely associated with multiple clinicopathological characteristics such as prognosis, tumor differentiation, TNM stage, and lymph node metastasis. Functionally, gain- and loss-of-function of SNHG14 revealed that overexpressed SNHG14 promoted cancer cell viability, invasion, and migration, whereas its down-regulation produced the opposite effect. Mechanistically, regulating its target gene expression by sponging distinct miRNAs might be the major mechanism underlying the oncogenic functions of SNHG14. Thus, SNHG14 might be a promising prognostic biomarker and therapeutic target for cancers. In this review, we discuss the expression profile, biological function, and molecular mechanisms of SNHG14 in cancers to provide a molecular basis for the clinical utility of SNHG14 in the future.
