Background: The dysregulation of microRNAs has been implicated in the progression of different malignancies. Herein, we sought to identify the precise roles of miR-155-5p in the progression of cervical cancer. Materials and methods: The expressions of miR-155-5p in cervical carcinoma cells and clinical tissues were assessed using qRT-PCR analysis. The functions of miR-155-5p on the growth of cervical cancer cell were investigated using MTT and colony formation. The Transwell and wound closure assays were selected to explore the influence of miR-155-5p on the invasion and migration of cervical cancer cell. The effect of miR-155-5p on cervical carcinoma cell growth and metastasis in vivo was investigated using xenograft model and experimental lung metastasis model. Bioinformatics analysis and luciferase reporter assay were applied to identify that tumor protein p53-inducible nuclear protein 1 (TP53INP1) was the target of miR-155-5p. Results: MiR-155-5p was significantly upregulated in cervical cancer tissue than that in control normal tissue. Downexpression of miR-155-5p decreased the growth, migration as well as invasiveness abilities of cervical cancer cell in vitro whereas overregulation of miR-155-5p caused the opposite outcomes. In addition, the in vivo mice xenograft model suggested that downexpression of miR-155-5p restrained the progression of cervical cancer cell whereas overexpression of miR-155-5p caused opposite outcomes. Furthermore, we revealed that TP53INP1 was the target of miR-155-5p and the level of TP53INP1 was inversely associated with miR-155-5p level in cervical carcinoma. Furthermore, TP53INP1 knockdown mimicked the influence of miR-155-5p on cervical cancer proliferation, migration and invasion phenotypes. Finally, overexpression of TP53INP1 impaired the promote effect of miR-155-5p on cervical cancer cell and downregulation of TP53INP1 counteracted the suppressive impact of miR-155-5p on the aggressiveness of cervical cancer cell. Conclusion: Our study indicated that miR-155-5p regulated the development of cervical cancer cell by regulating the expression of TP53INP1.
