The intricate crosstalk between long noncoding RNAs (lncRNAs) and epigenetic modifications such as chromatin/histone methylation acetylation offer new perspectives on the pathogenesis treatment of kidney diseases. lncRNAs, a class transcripts longer than 200 nucleotides with no protein-coding potential, are now recognized key regulatory molecules influencing gene expression through diverse mechanisms. They modulate by recruiting or blocking enzymes responsible for adding removing methyl acetyl groups, DNA, N6-methyladenosine (m6A) histone acetylation, subsequently altering chromatin structure accessibility. In diseases acute injury (AKI), chronic disease (CKD), diabetic nephropathy (DN), glomerulonephritis (GN), renal cell carcinoma (RCC), aberrant patterns DNA/RNA/histone have been associated onset progression, revealing complex interplay lncRNA dynamics. Recent studies highlighted how lncRNAs can impact pathology affecting function genes involved in cycle control, fibrosis, inflammatory responses. This review will separately address roles diseases, particular emphasis elucidating bidirectional effects underlying mechanisms conjunction addition to potential exacerbating renoprotective pathologies. Understanding reciprocal relationships not only shed light molecular underpinnings pathologies but also present avenues therapeutic interventions biomarker development, advancing precision medicine nephrology.

Abstract Background LncRNA AK044604 (regulator of insulin sensitivity and autophagy, Risa ) autophagy-related factors Sirt1 GSK3β play important roles in diabetic nephropathy (DN). In this study, we sought to explore the effect on Sirt1/GSK3β-induced podocyte injury. Methods Diabetic db/db mice received -inhibition adeno-associated virus (AAV) via tail vein injection, intraperitoneal injection lithium chloride (LiCl). Blood, urine, kidney tissue samples were collected analyzed at different time points. Immortalized mouse cells (MPCs) cultured treated with lentivirus (LV), EX-527, LiCl. MPCs under stimulations as noted. The effects autophagy examined by qRT-PCR, Western blotting analysis, transmission electron microscopy, Periodic Acid-Schiff staining, immunofluorescence staining. Results activated overexpressed, but was downregulated DN high glucose-treated ( P < 0.001, db/m vs. db/db, NG or HM HG), which correlated poor prognosis. overexpression attenuated Sirt1-mediated downstream levels aggravated injury inhibiting expression HG). contrast, suppression enhanced Sirt1-induced injury, could be abrogated EX-527 + -AAV HG -LV Furthermore, LiCl treatment restore GSK3β-mediated podocytes suggesting that decreasing autophagy.

Autophagy is a ubiquitous intracellular cytoprotective quality control program that maintains cellular homeostasis by recycling superfluous cytoplasmic components (lipid droplets, protein, or glycogen aggregates) and invading pathogens. Mitophagy selective form of autophagy damaged mitochondrial material, which can extracellularly act as damage-associated molecular patterns, prevents their release. mitophagy are indispensable for the maintenance kidney exert crucial functions during both physiological disease conditions. Impaired negatively impact pathophysiological state promote its progression. helps in maintaining structural integrity kidney.

BACKGROUND Periodontitis, when exacerbated by diabetes, is characterized increased M1 macrophage polarization and decreased M2 polarization. O-linked β-N-acetylglucosamine (O-GlcNAcylation), catalyzed O-GlcNAc transferase (OGT), promotes inflammatory responses in diabetic periodontitis (DP). Additionally, p38 mitogen-activated protein kinase regulates However, the interplay between OGT, polarization, signaling progression of DP remains unexplored. AIM To investigate effect OGT on its role mediating O-GlcNAcylation p38. METHODS For vivo experiments, mice were divided into four groups: Control, model, model + short hairpin (sh) RNA-negative control, sh-OGT. Diabetes was induced streptozotocin, followed ligation lipopolysaccharide (LPS) administration to induce periodontitis. The impact assessed injecting sh-OGT lentivirus. Maxillary bone destruction evaluated using micro-computed tomography analysis tartrate-resistant acid phosphatase staining, while determined through quantitative real-time polymerase chain reaction (qPCR) immunohistochemistry. vitro RAW264.7 cells treated with LPS high glucose (HG) (25 mmol/L D-glucose) establish a cell DP. inhibited inhibitor (OSMI4) treatment knocked down transfection. M1/M2 analyzed qPCR, immunofluorescence, flow cytometry. Levels measured immunoprecipitation western blotting. RESULTS Our results demonstrated that led maxillary loss mice, associated elevated levels. Knockdown promoted shift from both mouse periodontal tissues HG-induced cells. Furthermore, HG enhanced interacted promote at residues A28, T241, T347, as well phosphorylation residue Y221.

Extracellular vesicles (EVs) from mesenchymal stem cells (MSCs) have emerged as promising agents. This study explored effects and mechanisms EVs derived human placental (hP-MSCs) on DKD. were isolated cultured hP-MSCs administered to streptozotocin (STZ)-induced diabetic mice high glucose–treated glomerular mesangial cells. The impact was assessed through histological analysis biochemical assays. miR-99b-5p expression in its role modulating mechanistic target rapamycin (mTOR)/autophagy pathway examined via western blotting RT‒qPCR. Treatment with hP-MSC-derived significantly alleviated fibrosis improved function DKD models. These enriched miR-99b-5p, which targeted inhibited mTOR signaling, thereby increasing autophagic activity reducing cellular proliferation extracellular matrix accumulation tissues. can mitigate injury by miR-99b-5p/mTOR/autophagy pathway. findings suggest potential cell-free strategy for managing
