Previous studies have shown that miRNAs involved in a number of biological processes, such as cell growth, development, differentiation, and apoptosis. The dysregulation of miRNA expression is associated with various diseases, including cervical cancer. However, the involvement of miR‐3647‐5p in the progression of tumors is unclear. In this study, we confirmed that miR‐3647‐5p was down‐regulated during cervical carcinogenesis and development, which was positively correlated with the prognosis of patients with cervical cancer. In addition, our study showed that miR‐3647‐5p can inhibit the proliferation of cervical cancer cells and promote apoptosis, suggesting that miR‐3647‐5p is involved in the development of cervical cancer as a tumor suppressor gene. Furthermore, we found that transcription factor TP53 could promote the expression of miR‐3647‐5p, suggesting that the dysfunction of miR‐3647‐5p in cervical cancer may be related to TP53. In addition, we also found that miR‐3647‐5p can inhibit the proliferation of cervical cancer cells and promote apoptosis by targeting AGR2. In summary, our research reveals that transcription factor TP53 promotes the expression of miR‐3647‐5p, while up‐regulated miR‐3647‐5p targets AGR2, inhibiting cervical cancer cell proliferation and promoting apoptosis. Our study reveals the mechanism of TP53/miR‐3647‐5p/AGR2 axis in cervical cancer, which may be useful for targeted therapy of cervical cancer.
