MicroRNAs (miRNAs) are key molecules that regulate gene expression. miRNAs regulate protein synthesis by binding to mRNA, influencing processes such as cell proliferation, metastasis, and apoptosis. They play a pivotal role in cancer development. Current research mainly explores miRNA mechanisms and applications, and the techniques underpinning this research are foundational to both basic science and clinical translation. However, no review has comprehensively examined miRNA mechanisms and applications from a technical perspective, creating a need for this work. Advances in RNA sequencing technology, CRISPR/Cas9 technology, and bioinformatics tools have deepened our understanding of miRNA interactions. miRNA can serve as a biomarker for cancer diagnosis and prognosis, with significant clinical potential. The development of miRNA mimics and inhibitors has brought new hope for cancer treatment, especially in reversing cancer drug resistance. This article reviews the vital role of miRNA interactions in cancer occurrence, development, diagnosis, and treatment, providing new perspectives and strategies for personalized medicine and cancer therapy.

The human phosphatase and tensin homolog (PTEN) is a tumor suppressor. A slight deficiency in PTEN might cause cancer susceptibility and progression. Infection by the liver fluke Clonorchis sinensis could lead to persistent loss of PTEN in cholangiocarcinoma. However, the mechanism of PTEN loss and its malignant effect on cholangiocarcinoma have not yet been elucidated. Extracellular vesicles secreted by Clonorchis sinensis (CS-EVs) are rich in microRNAs (miRNAs) and can mediate communication between hosts and parasites. Herein, we delved into the miRNAs present in CS-EVs, specifically those that potentially target PTEN and modulate the progression of cholangiocarcinoma via ferroptosis mechanisms. CS-EVs were extracted by differential ultra-centrifugation for high-throughput sequencing of miRNA. Lentiviral vectors were used to construct stably transfected cell lines. Erastin was used to construct ferroptosis induction models. Finally, 36 miRNAs were identified from CS-EVs. Among them, csi-miR-96-5p inhibited PTEN expression according to the predictions and dual luciferase assay. The CCK-8 assay, xenograft tumor assays and transwell assay showed that csi-miR-96-5p overexpression and PTEN knockout significantly increased the proliferation and migration of cholangiocarcinoma cells and co-transfection of PTEN significantly reversed the effect. In the presence of erastin, the cell proliferation and migration ability of the negative transfection control group were significantly impaired, although they did not significantly change with transfection of csi-miR-96-5p and PTEN knockout, indicating that they obtained ferroptosis resistance. Mechanistically, csi-miR-96-5p and PTEN knockout significantly inhibited ferroptosis through a decrease in ferrous ion (Fe2+) and malondialdehyde (MDA), and an increase in glutathione reductase (GSH), Solute carrier family 7 member 11 (SLC7A11) and glutathione peroxidase 4 (GPX4). In conclusion, loss of PTEN promoted the progression of cholangiocarcinoma via the ferroptosis pathway and csi-miR-96-5p delivered by CS-EVs may mediate this process.
