Long noncoding RNA (lncRNA) cardiac mesoderm enhancer-associated noncoding RNA () is a newly discovered tumor-suppressor lncRNA in cancers. However, its role in cervical cancer (CC) remains elusive. This study was conducted to analyze the molecular mechanism of in CC cell growth and provide a novel theoretical basis for CC treatment. RT-qPCR and clinical analysis revealed that and B-cell translocation gene 2 () were downregulated, whereas was upregulated in CC tissues and cells and their expressions were correlated with clinicopathological characteristics and prognosis. MTT assay, flow cytometry, and Transwell assays revealed that overexpression reduced proliferation, migration, and invasion and increased apoptosis rate in CC cells. Mechanically, repressed to promote transcription. Functional rescue assays revealed that overexpression or downregulation reversed the inhibitory role of overexpression in CC cell growth. Western blot analysis elicited that Wnt3a and β-catenin were elevated in CC cells and blocked the Wnt/β-catenin signaling pathway via the axis. Overall, our findings demonstrated that repressed to upregulate transcription and then blocked the Wnt/β-catenin signaling pathway, thereby suppressing CC cell growth.
