MIR199A (MicroRNA 199a)

From a therapeutic point of view, miR-199a-3p replacement synergized with palbociclib and overcame sorafenib resistance. This review highlights the importance of the TG221 transgenic mouse as a powerful model for studying miRNA-driven hepatocarcinogenesis and enables preclinical evaluation of RNA-based chemopreventive and therapeutic approaches. Metformin, miRNA inhibition, miRNA replacement and miRNA-guided viral therapies emerge as promising approaches for advancing precision prevention and treatment strategies in HCC.

m214-sEV treatment reprograms secondary tumor-derived sEVs toward a less prometastatic cargo profile and decreases carboplatin resistance and cell migration. Enforced YKT6 overexpression abrogates these effects, establishing YKT6 as a key downstream effector. Collectively, these findings support engineered sEVs as a translatable strategy to overcome chemoresistance and disrupt pro-tumorigenic EV signaling in recurrent OC.

LncRNA NPSR1-AS1 targets miR-199a-3p and affects the progression of BCa. Moreover, it can serve as a biomarker for BCa.

miRNAs show potential as non-invasive markers for early detection and prognosis of HCC. This review emphasises the potential of miRNAs as non-invasive indicators for the diagnosis and prognosis of HCC. Nonetheless, the variability across studies and the absence of methodological consistency restrict their prompt application in clinical settings. It is crucial to validate findings through extensive, multicentre studies and to integrate them with traditional diagnostic methods to guarantee their relevance in clinical practice. Future research should focus on confirming miRNA panels and integrating them into current diagnostic methods.

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.

In the training and validation sets, the area under the curve of the 4-miRNA panel was 0.909 and 0.942, respectively. These findings suggest that the serum glycosylated exosomal 4-miRNA panel developed using the GlyExo-Capture approach may serve as a promising strategy for liquid biopsy-based early detection of LUAD.

PDHA1, OGG1, and OPA1 were identified as potential prognostic markers for pediatric AML, providing valuable insights for the development of targeted therapeutic strategies. However, further validation in larger and more diverse clinical cohorts is still required to confirm its clinical applicability.

These findings underscore the critical roles of miR-125b-5p and miR-100-5p in PM-associated lung cancer progression and their potential as biomarkers and therapeutic targets. This study highlights distinct mechanisms of lung carcinogenesis in smokers and non-smokers, providing a foundation for targeted interventions in PM-associated lung cancer.

In vivo studies confirmed that either overexpression of LINC01133 or inhibition of miR-199a-5p suppresses gastric adenocarcinoma cell growth. In summary, LINC01133 re-activation may serve as a potential therapeutic strategy for inhibiting metastasis in gastric adenocarcinoma.

The high expression of miR-199a-5p can inhibit SLC1A5 and thus the progression of NPC. At the same time, the high expression of miR-199a-5p can increase the sensitivity of NPC to cisplatin.

Collectively, these findings demonstrate that miR‑199a‑3p suppresses NSCLC progression by targeting FTO, promoting m6A methylation‑dependent downregulation of MZF1, and consequently decreasing CLDND1 expression. Thus, the miR‑199a‑3p/FTO/MZF1/CLDND1 axis may serve as a promising therapeutic target in NSCLC.
