Several EMT-related miRNAs show consistent associations with invasion, metastasis, peritoneal dissemination, prognosis, and chemoresistance, and many are detectable in circulation. Overall, EMT-related miRNAs orchestrate gastric cancer cell plasticity and tumor-microenvironment crosstalk and represent promising biomarker and therapeutic candidates that warrant validation in prospective, subtype-stratified, and translational studies.
miR-17-5p mimics partially reversed these effects. Carnosol may exert its radiosensitizing effect in NSCLC by targeting the miR-17-5p/TOLLIP/NF-κB axis and disrupting DNA repair, highlighting its therapeutic potential in overcoming radioresistance.

Our findings suggest that miR-20a-5p plays an oncogenic role in luminal breast cancer by promoting EMT, while MALAT1 may contribute to disease progression through indirect regulatory mechanisms. Finally, MALAT1 and miR-20a-5p might serve as potential therapeutic and prognostic targets in LBC.
This review provides a comprehensive overview of the current and future applications of liquid biopsy in TNBC management, highlighting its potential to improve early disease detection, optimize therapeutic strategies, and refine patient classification. Integrating liquid biopsy into routine clinical practice could lead to better treatment outcomes and more personalized approaches to TNBC care.
Importantly, therapeutic responses in vivo substantially exceeded predictions based on in vitro tumor cell proliferation and motility measurements, revealing critical contributions of systemic immunomodulation. These findings demonstrate that miRNA inhibition reshapes tumor-immune interactions, positioning anti-miRNA therapeutics as immunomodulatory agents for effective colorectal cancer treatment.
The gradual increase in specific miRNAs with lesion severity and HPV infection suggests their role in cervical carcinogenesis. The identified miRNAs may serve as promising non-invasive biomarkers for early detection and monitoring of HPV-associated cervical lesions.
While novel therapies such as rituximab and polatuzumab vedotin have led to improved outcomes, approximately 35% of patients eventually develop relapsed or refractory disease. Among these, miR-155 and miR-21 are particularly well studied, playing central roles in both tumor progression and remodeling of the tumor microenvironment. This review summarizes current evidence on the biological and clinical relevance of miRNAs in DLBCL, emphasizing their diagnostic and prognostic potential.
In the myoblast model system, transduction studies with exogenous miR-17-92 or miRNA-sponge expression constructs indicated that miR-17-92 is necessary but not sufficient for oncogenic transformation. Together, these findings establish a cooperative transcriptional axis in FP-RMS involving P3F and MYCN that activates MIR17HG through a distal regulatory element, thereby contributing to oncogenic behavior and uncovering a novel mechanistic vulnerability.
Background: HER2-positive breast cancer patients receiving chemotherapy and targeted therapy (including anthracyclines and trastuzumab) face an elevated risk of cardiotoxicity, which can lead to long-term cardiovascular complications... Circulating miRNAs show promise as biomarkers for predicting cardiotoxicity in breast cancer patients. Machine learning approaches may enhance miRNA-based risk stratification, enabling personalized monitoring and early cardioprotective interventions.
miRNA-targeted mesyl phosphoramidate oligonucleotides are effective tools for overcoming resistance to the clinically approved chemotherapeutics cisplatin and doxorubicin. The relationship between miR-21, miR-17, and miR-155 and the novel MDR markers such as SEH1L, TUBA4A, and ZYX was revealed, thereby expanding the current understanding of the molecular mechanisms underlying tumor cell resistance to chemotherapy.

A weak negative correlation between PTEN and three miRNAs, and weak positive correlations between CCND1 and miR-106b-5p and also TP53 and miR-20a-5p were observed. These findings emphasize the potential role of HPV and related biomarkers in the progression of breast cancer, indicating avenues for further research and therapeutic strategies.
Animal experiments confirmed its role in promoting tumor growth and lung metastasis. Exosomal miR-17-5p remodels the pulmonary microenvironment into a pro-inflammatory niche, facilitating thyroid cancer colonization and offering a potential therapeutic target.
