Non-healing lesions in diabetic foot ulcers are a significant effect of poor angiogenesis. Epigenetic regulators, mainly lncRNA and miRNA, are recognized for their important roles in disease progression. We deciphered the regulation of lncRNA NEAT1 through the miR-146a-5p/mafG axis in the progression of DFU. A lowered expression of lncRNA NEAT1 was associated with dysregulated angiogenesis through the reduced expression of , , and in chronic ulcer subjects compared to acute DFU. This was validated by silencing NEAT1 by SiRNA in the endothelial cells which resulted in the transcriptional repression of target genes. Our in silico analysis identified miR-146a-5p as a potential target of lncRNA NEAT1. Further, silencing NEAT1 led to an increase in the levels of miR-146a-5p in chronic DFU subjects. This research presents the role of the lncRNA NEAT1/miR-146a-5p/mafG axis in enhancing angiogenesis in DFU.

This study identifies a transcriptomic profile of long noncoding RNAs in gingival crevicular fluid samples in pregnant women with gestational diabetes risk. NEAT1 and LINC-PINT were increased expression in gingival crevicular fluid samples in pregnancies later diagnosed with gestational diabetes mellitus.

This study, based on datasets from healthy tissues, lactating mammary epithelial cells, and breast cancer phenotypes, investigates mammary gland pathophysiology at single-cell resolution to identify key regulators in breast cancer development and to gain a deeper understanding of its biology and heterogeneity. We suggest that antileukoproteinase (SLPI) has prognostic value associated with metastasis in basal breast cancers. Our analysis highlights the similarity between triple-negative breast cancer cells and mature luminal lactocytes, which share active regulons (SOX2, MTHFD1, POU4F3, and ZNF32), suggesting conserved molecular mechanisms.

Objectives: To study the molecular mechanisms of LDH-loaded si-NEAT1 for regulating paclitaxel resistance and tumor-associated macrophage (TAM) polarization in breast cancer.
Methods: qRT-PCR and Western blotting were used to detect the expression of lncRNA NEAT1, miR-133b, and PD-L1 in breast cancer SKBR3 cells and paclitaxel-resistant SKBR3 cells (SKBR3-PR). The effects of transfection with si-NEAT1 and miR-133b mimics on MRP, MCRP and PD-L1 expressions and cell proliferation, migration and apoptosis were investigated using qRT-PCR, Western blotting, scratch and Transwell assays, and flow cytometry.

Cellular senescence is accompanied by extensive genomic reorganization, such as senescence-associated heterochromatin foci and expanded interchromatin compartments, to ultimately affect gene expression. Here, we demonstrate that chromatin structural changes in senescent cells drive significant alterations in the phase behavior and motility of paraspeckles, a type of interchromatin compartment condensate. We observe increased numbers, size, and elongation of paraspeckles harboring NONO and NEAT1_2, driven by elevated levels of those components, consistent with the micellization model of longitudinal growth rather than condensate coalescence.

Childhood acute lymphoblastic leukaemia (chALL) remains the most prevalent malignancy in children and adolescents. Improving risk stratification and providing personalized prognosis and treatment remain major clinical challenges. Herein, we analysed the clinical utility of NEAT1 lncRNA for the prognosis and prediction of treatment outcome of childhood B-cell precursor ALL (chB-ALL).
