MIR135B (MicroRNA 135b)

Furthermore, pharmacological inhibition of HIF1α using PX‑478 abrogated hypoxia‑induced NED and attenuated activation of AKT/mTOR signaling, further underscoring the significance of the miR‑135b‑5p‑HIF1AN‑HIF1α axis in NED of PCa cells. Collectively, the findings of the present study reveal a novel miR‑135b‑5p‑HIF1AN‑HIF1α signaling axis that is involved in hypoxia‑induced NED via AKT/mTOR activation and identify miR‑135b‑5p and HIF1α as potential therapeutic targets for NEPC.

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.

Supratentorial ependymomas with ZFTA-RELA fusions represent a highly aggressive pediatric brain tumor subtype, yet the post-transcriptional mechanisms driving their malignancy remain unclear. This study fills a critical gap by systematically profiling miRNA expression in fusion-positive and fusion-negative supratentorial ependymomas, revealing a distinct fusion-associated miRNA signature. The identification of hsa-miR-138-5p upregulation and hsa-miR-135b-5p/hsa-miR-216a-3p downregulation, converging on key oncogenic nodes such as TERT, YAP1, RELA, and TP53, provides novel mechanistic insight into how fusion-driven miRNA dysregulation enhances epithelial-mesenchymal transition and stemness. The findings suggest that miRNA-fusion interactions play an important role in tumor aggressiveness and highlight hsa-miR-138-5p as a potential biomarker for disease progression. Clinically, the work advances understanding of fusion-driven ependymoma biology and lays the foundation for developing miRNA-based diagnostic and therapeutic strategies targeting molecular mechanisms of tumor progression.

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.

Distinct mirna signatures differentiate radiation-resistant and radiation-sensitive prostate cancer cells. Mir-20a-5p, mir-128-3p, and mir-135b-5p may contribute to radioresistance, whereas mir-23b-3p and mir-381-3p may act as radiosensitizers.

Interpretation & conclusionsmiR-135b-5p and miR-21-5p act synergistically as oncomiRs by suppressing LIMD1 and VHL, promoting HIF-1α-mediated cervical cancer progression. This study demonstrated the synergistic oncogenic role of miR-135b-5p and miR-21-5p in cervical cancer via co-regulation of the LIMD1-VHL-HIF-1α axis.

Multivariate Cox regression analysis indicated that both were independent prognostic factors for OSCC. Conclusion The miR-135b-5p/TXNIP axis critically regulates OSCC progression through ferroptosis and may serve as a prognostic biomarker and therapeutic target for OSCC.

Our findings emphasize the intricate transcriptomic profiles in oral leukoplakia and proliferative verrucous leukoplakia development, laying the groundwork for future studies to enhance clinical management and patient outcomes in oral oncology. Syndecan 3 gene polymorphisms may represent a key point in proliferative verrucous leukoplakia differential diagnosis and prognostic prediction.

Emerging microbiota-based therapies, including probiotics and fecal microbiota transplantation, show promise in modulating gut flora and potentially reversing ncRNA dysregulation; however, their mechanistic effects on the F. nucleatum-ncRNA axis require further investigation. This review underscores the critical role of F. nucleatum-regulated ncRNAs in CRC and presents new opportunities for biomarker discovery and targeted therapeutics.

Our findings suggest that miR-135b overexpression in PCOS ovaries contributes to abnormal granulosa cell proliferation by inhibiting the Hippo pathway. This study enhances our understanding of ovarian abnormalities in PCOS and identifies miR-135b as a potential biomarker and therapeutic target for the disorder.

In contrast to the clathrin-dependent pathway, the caveolae-mediated endocytosis and the macropinocytosis of the AuNPs resulted in the effective targeting and reduction of the miR 135b. The bio-produced AuNPs can effectively enter mammalian cells simultaneously by different endocytic pathways but the delivery of functional cargo is not achieved via the clathrin-dependent endocytosis.
