Long noncoding RNAs (lncRNAs) act as essential regulators in cancer tumorigenesis. Our study aimed to explore the underlying mechanism of lncRNA human leukocyte antigen complex group 11 (HCG11) in cervical cancer (CC) progression. Long noncoding RNA HCG11 was downregulated in CC. Functional assays demonstrated that lncRNA HCG11 inhibited CC cell proliferation and invasion. Then, we confirmed that lncRNA HCG11 could directly bind to miR‐942‐5p. Moreover, inhibition of miR‐942‐5p suppressed the growth and invasion of CC cells, and growth factor‐independent transcription repressor 1 ( GFI1 ) gene was the target gene of miR‐942‐5p. Long noncoding RNA HCG11 increased the expression of GFI1 and suppressed cell proliferation and invasion by acting as a miR‐942‐5p sponge. Finally, the overexpression of lncRNA HCG11 suppressed the proliferation and metastasis of CC cells in vivo.
