The prognostic value of miR-127-5p in cervical squamous cell carcinoma and its role in suppressing malignant behavior of cancer cells via SNX10 inhibition
摘要
Cervical squamous cell carcinoma (CESC) is the most common pathological type of cervical cancer. This study aimed to investigate the clinical relevance and functional role of miR-127-5p in CESC.
MethodThis study analyzed miR-127-5p expression in tumor and paired adjacent tissues from 134 CESC patients, and evaluated its association with clinicopathological features and prognosis using Kaplan-Meier and Cox regression analyses. The effects of miR-127-5p on cell functions were assessed by CCK-8 and Transwell assays, and its interaction with SNX10 was investigated using dual-luciferase and rescue experiments.
ResultsIn CESC tissues, miR-127-5p was significantly downregulated and this downregulation correlated with advanced FIGO stage and positive lymph node metastasis. Kaplan-Meier analysis showed that patients in the low miR-127-5p expression group had a lower 5-year survival rate. Cox regression analysis indicated that miR-127-5p is an independent factor affecting patient prognosis. Overexpression of miR-127-5p suppressed CESC cell proliferation, migration, and invasion by directly targeting the 3’UTR of SNX10, with rescue experiments identifying SNX10 as a key functional mediator that regulates EMT and autophagy-related pathways.
ConclusionsmiR-127-5p is lowly expressed in CESC and can serve as a potential prognostic biomarker. MiR-127-5p may inhibit the malignant behavior of CESC cells by targeting SNX10.
