چکیده انگلیسی
MicroRNAs (miRNAs) are important regulators in tumorigenesis and progression of multiple human cancers, including ovarian cancer (OC). As a member of miRNAs family, miR-374b-5p has been reported to be a tumor suppressive gene in human cancers. In this study, the lower expression of miR-374b-5p was identified in OC tissues and cell liens using quantitative real time PCR (qRT-PCR). Forkhead box protein P1 (FOXP1) can act as an oncogene in human cancers. Mechanism experiments revealed that FOXP1 is a target of miR-374b-5p. Functionally, miR-374b-5p suppressed cell proliferation, migration and epithelial-mesenchymal transition (EMT) in ovarian cancer. Moreover, the sensitivity of OC cells to cisplatin was markedly enhanced by miR-374b-5p. However, FOXP1 reversed However, FOXP1 reversed miR-374b-5p-mediated biological functions. Previous reports demonstrated the inhibitory effect of FOXP1 on transcription FOXP1. Thus, we further examined the effect of FOXP1 on the transcription activity of miR-374b-5p in OC cells. The results showed that FOXP1 decreased miR-374b-5p expression by inhibiting the transcription activity of miR-374b-5p. Rescue assays revealed the regulatory effect of miR-374b-5p-FOXP1 feedback loop on ovarian cancer progression. In conclusion, miR-374b-5p-FOXP1 feedback loop regulates tumor progression and chemosensitivity in ovarian cancer.
