MIR302B (MicroRNA 302b)

FKBPL-based peptide mimetic, AD-01 (1 nM), in high-glucose conditions, upregulated endothelial vcam1 and glut1 mRNA expression, independent of miR-302b-5p. FKBPL plays an important role in glucose metabolism, endothelial function, angiogenesis, cardiac inflammation and function, and could be explored as a therapeutic target of cardiovascular disease both in nondiabetes and diabetes settings using precision medicine approach.

The study by Bi et al. (2025) presents "Senoreverse", an innovative strategy that utilizes exosomal miR-302b to restore the proliferative capacity of senescent cells (SnCs), thus extending lifespan and enhancing cognitive and physical function in aging mice without the risk of tumorigenicity.

In conclusion, this study provides evidence for the potential role of MGLL and microRNAs (miR-302b-5p, miR-190a-3p, miR-450a-2-3p) in NSCLC. In subsequent studies, it was determined that MSRB3, FCER1G and LTB4R2 genes, especially the HTR4 gene, could be potential target genes for lung cancer.

The study recommends that restoring the expression of tumor suppressor miRNAs may be a suitable cancer therapy. Utilizing this technology does present certain difficulties, and resolving them will improve the methods for miRNA transfer to target cells. With more research and the resolution of associated issues, miRNA can be employed as an efficient therapeutic method for OSCC.

Notably, miR-302b-3p exhibited a significant association with all the evaluated clinical features. Our findings suggest that miRNAs have the potential to aid in the diagnosis, prognosis, and management of patients with malignant GCTs.

The circulating serum miR-133b and miR-206 can serve as significant biomarkers for monitoring the clinical outcome of progression with metastatic CRC patients. Increased drug-responsive CRC patients associated with crucial molecular intervention should be further explored, clinically.

Metformin inhibited RFA-deficiency-induced HCC growth and tumor vascular abnormalities in vivo. Overall, metformin promotes the normalization of abnormal blood vessels after RFA deficiency in HCC by miR-302b-3p targeting TXNIP, which can be used to prevent the progression of HCC after RFA.

The expression of UBE2R2-AS1 allowed the prognostic stratification of gastric cancer patients. UBE2R2-AS1 may accelerate the progression of gastric cancer via miR-302b-5p.

In addition to malignant conditions, ZEB1-AS1 has functional role in non-malignant conditions like diabetic nephropathy, diabetic lung, arthrosclerosis, Chlamydia trachomatis infection, pulmonary fibrosis and ischemic stroke. This review outlines different molecular mechanisms of ZEB1-AS1 in a variety of disorders and highlights its importance in their pathogenesis.

This study highlights the altered expression of miRNA in gingiva, and their expression depends on the time-points of infection. This is the first in vivo study that identified specific signature miRNAs (miR-103 and miR-30d) in P. gingivalis invasion of epithelial cells, establishes a link between miRNA and development of periodontitis and helping to better understand the pathobiology of periodontitis.

These six microRNAs were related to the clinical-pathological characteristics (histological types, risk, metastasis, AFP marker, survival) and miR-302b-3p was the only one that showed significant correlation with all events. Yolk sac tumor showed significant overexpression of miR-302b-3p compared with embryonal carcinoma, teratomas, and dysgerminoma.ConclusionsOur results suggest that miRNA-302b-3p are promising candidate biomarkers in malignant GCTs and miRNAs may improve the quality of the care of patients, contributing to personalized medicine.

FAM230B is accumulated to high levels in OS and may serve as an endogenous competing RNA for premature miR-302b in the nucleus to promote OS cell invasion and migration.
