Abstract The etiology of epilepsy is ascribed to the synchronized aberrant neuronal activity within brain. Circular RNAs (circRNAs), a class non‐coding characterized by their circular structures and covalent linkage, exert substantial influence on this phenomenon. CircRNAs possess stereotyped replication, transience, repetitiveness, paroxysm. Additionally, MicroRNA (miRNA) plays crucial role in regulation diverse pathological processes, including epilepsy. CircRNA particular significance due its ability function as competing endogenous RNA, thereby sequestering or inhibiting miRNA through binding target mRNA. Our review primarily concentrates elucidating functional roles, well underlying mechanisms, circRNA–miRNA–mRNA networks it explores potential utility these for early detection therapeutic intervention.

Temporal lobe epilepsy (TLE), a prevalent neurological disorder, is associated with hippocampal oxidative stress and inflammation. A recent study reveals that the long noncoding RNA ILF3 divergent transcript (ILF3-AS1) level elevated in hippocampus of TLE patients; however, functional roles ILF3-AS1 underlying mechanisms deserve further investigation. Hence, this aimed to elucidate whether involved pathogenesis by regulating inflammation explore its mechanism vitro.

Reactivation of fetal hemoglobin (Hb F, α2γ2) has been demonstrated to be a therapeutic strategy for patients with β-hemoglobinopathies. MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression by silencing RNA. Both coding and non-coding can compete the same miRNAs, acting as competing endogenous (ceRNAs). However, role ceRNAs in β-thalassemia major (β-TM) their impact on γ-globin remains poorly understood. In this study, we conducted transcriptome sequencing collect circularRNA (circRNA), miRNA, mRNAs from β-TM healthy individuals. Through bioinformatics analysis, constructed GATA2‑associated ceRNA network, emphasizing hsa_circ_0005245_hsa-miR-425-3p_GATA2 pathway. Validation using qRT-PCR analysis samples, RNA immunoprecipitation, dual-luciferase reporter assays confirmed Furthermore, overexpression hsa_circ_0005245, hsa-miR-425-3p, GATA2 HUDEP-2 cells individually resulted elevated levels. Our findings identify novel pathway regulates expression, providing potential insights clinical management patients.

Diabetic retinopathy (DR) is the leading manifestation of diabetic microangiopathy. However, effective biomarkers and therapies are lacking. Circular RNAs (circRNAs) have been implicated in various diseases including DR. role circRNAs DR remains elusive. In present study, circNXN was upregulated high glucose (HG)-treated human retinal microvascular endothelial cells (hRMECs). knockdown inhibited proliferation, migration, angiogenesis hRMECs promoted apoptosis. addition, acted as a sponge for miR-338-3p to facilitate FGFR1 (fibroblast growth factor receptor 1) expression. Furthermore, rescue assays revealed that reduced promoting effect on induced by could be reversed inhibitor HG-treated hRMECs. Additionally, rat model, downregulation ameliorated vasculature changes. Our findings reveal new therapeutic strategy may provide approach clinical therapy.

Diabetic kidney disease (DKD), characterized by mesangial fibrosis and renal dysfunction, is a major microvascular complication of diabetes. Studies have shown that miRNAs are closely related to the progression DKD. Therefore, in this study, we aimed explore whether miR-1225-3p can regulate Smad ubiquitin regulatory factor 2 (SMURF2)-mediated carbohydrate response element binding protein (ChREBP) ubiquitination through Rho GTPase-activating 5 (ARHGAP5) affect DKD mice were established intraperitoneally injecting streptozocin (STZ), cell model was generated culturing media supplemented with 25 mmol/L glucose (high glucose, HG). StarBase used predict target sites between ARHGAP5, dual-luciferase reporter gene assay verify relationship. Western blotting, RT-qPCR, flow cytometry, immunoprecipitation, ELISAs, HE staining, Masson staining detect relevant indicators. ARHGAP5 SMURF2 expression decreased, but ChREBP highly expressed tissue HG-induced mouse cells (MMCs). could transcription an association revealed. facilitated oxidative stress MCCs inhibiting ARHGAP5. In addition, promoted HA-ChREBP, mediating ARHGAP5/SMURF2-mediated MCCs. Furthermore, inhibitor inhibited inflammation tissues mice. facilitates ChREBP.
