MIR200C (MicroRNA 200c)

Furthermore, members of the miR‑200 family have potential as diagnostic and prognostic biomarkers and are closely linked to chemotherapy resistance. The present review aims to provide novel insights and a theoretical foundation for the diagnosis, treatment, and deeper investigation of BC by comprehensively examining the functional mechanisms of the miR‑200.

MiR-200c restoration inhibits FOXP3 and suppresses metastatic progression in breast cancer. Targeting the miR-200c/FOXP3 axis presents a novel and promising therapeutic approach for advanced breast cancer.

It also covers microbiota-host interactions, including bidirectional links between gut microbes and miRNAs, effects on intestinal homeostasis, and microbial metabolites that alter miRNA expression. Recent advances in RNA-based therapeutic strategies and progress in clinical trials are included to frame the current translational relevance.

These networks revealed several molecular modules associated with patient survival outcomes, such as the miR-200c-3p/ZEB2 axis in bladder cancer, the regulatory role of miR-98 in breast cancer, as well as the association of miR-21 with target genes APC in kidney renal cell carcinoma. These findings suggest that omics-specific clustering can identify robust survival-related patient clusters and uncover molecular features that may contribute to differential survival outcomes.

Given the small sample size (n = 10), these findings should be interpreted as preliminary and hypothesis-generating, warranting validation in larger cohorts. Nevertheless, findings support household testing, remediation at ≥100 Bq/m3, and integrated exposure studies considering PM2.5 co-exposures.

Persistent challenges, including oxidative degradation, dose-dependent toxicity, and large-scale manufacturing, are addressed alongside promising innovations such as biodegradable surface coatings and machine-learning-assisted material design. Altogether, dual-miRNA theranostics using MXenes hold immense promise as transformative tools for precision treatment of metastatic bladder cancer.

Among the miRNA alterations associated with stage I adenocarcinoma in nonsmokers, we found alterations in all 5 miR-200 family members (miR-200b, miR-200a, miR-141, miR-429, and miR-200c). Our identification of miRNA alterations associated with early-stage lung adenocarcinoma in nonsmokers, especially alterations in the miR-200 family, suggests that these miRNAs may play a unique role in the early stages of lung carcinogenesis and progression in nonsmokers and that they may be useful as markers for the early detection of lung cancer.

The C/T genotype of rs11614913 in MIR196A2, and C/A genotype and A allele of rs2682818 in MIR618, are associated with a protective effect against BrC in women from western Mexico.

Evaluation of miRNAs commonly deregulated between the three groups showed 14 shared upregulated miRNAs (miR-429, miR-425-5p, miR-200c-3p, miR-200c-5p, miR-200b-3p, miR-200a-3p, miR-183-5p, miR-182-5p, miR-141-5p, miR-141-3p, miR-96-5p, miR-93-5p, miR-10a-5p, miR-10a-3p) with a progressive increase in expression levels, from ovarian EMS to TL and ultimately to ECOC. The identified miRNA expression profiles associated with the progression from ovarian EMS, TL and ECOC provide valuable insights into the molecular progression from benign to malignant lesions and could represent potential biomarkers for the early detection of ECOC.

The combination of miR-6134, CA125, HE4, and IL-6, or miR-6134 alone, shows potential as a serum biomarker for EOC, particularly in distinguishing malignant from benign ovarian tumors. The combination of two miRNAs also demonstrated high discriminative power in cases with CA125 below the cutoff. These findings may contribute to the development of improved non-invasive diagnostic tools and warrant further validation.

Multivariate analysis confirmed miR-200c as an independent predictor of resistance (OR: 20.90; 95% CI: 1.54-283.73). Conclusions This pilot study identifies circulating miR-19a, miR-21, and miR-200c as novel biomarkers for poor NAC response in GC, providing a foundation for personalized treatment strategies.

The ISL demonstrated potent anticancer effects by: (1) Inducing apoptosis and autophagy via mechanistic target of rapamycin (mTOR) inhibition and disruption of arachidonic acid pathways; (2) modulating microRNAs (miRs; e.g., miR-374a, miR-200c) to suppress epithelial-mesenchymal transition (EMT); (3) altering hormone receptor [HR; ERα, breast cancer type 1 susceptibility protein (BRCA1)] expression and inhibiting phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mTOR signaling; and (4) reducing angiogenesis [vascular endothelial growth factor (VEGF)/hypoxia-inducible factor-1 alpha (HIF-1α) suppression] and inflammation [cyclooxygenase-2 (COX-2)/nuclear factor-kappa B (NF-κB) inhibition]...However, clinical trials are urgently needed to validate its efficacy, safety, and optimal delivery strategies in patients. Future research should prioritize translational studies and combinatorial therapies to bridge the gap between bench and bedside.
