Abstract Background With the increasing incidence of steroid-induced necrosis femoral head (SNFH), numerous scholars have investigated its pathogenesis. Current evidence suggests that imbalance between lipogenesis and osteoblast differentiation in bone marrow mesenchymal stem cells (BMSCs) is a key pathological feature SNFH. MicroRNAs (miRNAs) strong gene regulatory effects can influence direction cell differentiation. N6-methyladenosine (m6A) prevalent epigenetic modification involved diverse pathophysiological processes. However, knowledge how miRNAs regulate m6A-related factors affect BMSC limited.

Abstract Periodontal disease ranks third among noncommunicable illnesses, behind cancer and cardiovascular disease, is closely related to the occurrence progression of various systemic diseases. However, elucidating processes periodontal promoting bone regeneration remains a challenge. Here, quercetin demonstrated reduce oxidative stress state orofacial mesenchymal stem cells (OMSCs) in vitro affect osteogenic growth OMSCs through molecular mechanisms that mediate m6A change Per1. Nevertheless, limited therapeutic efficacy medication limitations local resulting from small, moist, highly dynamic environment make it challenging treat tissues with medication. Herein, biosafe injectable hydrogel drug‐controlled delivery system constructed as bone‐enhancing factory loaded injury tissues. This drug‐carrying made up nanoscale bioglass microspheres light‐cured hydrogel, allows effective drug particle loading cementation moist environment.

Abstract Background D-2-hydroxyglutarate (D-2HG), an oncometabolite derived from the tricarboxylic acid cycle. Previous studies have reported diverse effects of D-2HG in pathophysiological processes, yet its role breast cancer remains largely unexplored. Methods We applied advanced biosensor approach to detect levels samples. then investigated biological functions through multiple vitro and vivo assays. A joint MeRIP-seq RNA-seq strategy was used identify target genes regulated by D-2HG-mediated N6-methyladenosine (m 6 A) modification. RNA pull-down assays were further reader that could specifically recognize m modification on angiopoietin like 4 (ANGPTL4) mRNA immunoprecipitation confirm findings. Results found accumulated triple-negative (TNBC), exerting oncogenic both promoting TNBC cell growth metastasis. Mechanistically, enhanced global modifications cells, notably upregulating ANGPTL4 mRNA, which mediated inhibition Fat-mass obesity-associated protein (FTO), resulting increased recognition A-modified YTH binding F1 (YTHDF1), thereby translation ANGPTL4. As a secretory protein, subsequently activated integrin-mediated JAK2/STAT3 signaling cascade cells autocrine signaling. Notably, knockdown or treatment with GLPG1087 (an integrin antagonist) significantly reduced D-2HG-induced proliferation metastasis cells. Additionally, promote macrophage M2 polarization within tumor microenvironment via paracrine signaling, driving progression. The association poor prognosis patients underscores clinical relevance. Conclusions Our study unveils previously unrecognized for progression targeting D-2HG/FTO/m A/ANGPTL4/integrin axis can serve as promising therapeutic patients.

Abstract Skeletal muscular atrophy is a complex disease involving large number of gene expression regulatory networks and various biological processes. Despite extensive research on this topic, its underlying mechanisms remain elusive, effective therapeutic approaches are yet to be established. Recent studies have shown that epigenetics play an important role in regulating skeletal muscle atrophy, influencing the numerous genes associated with condition through addition or removal certain chemical modifications at molecular level. This review article comprehensively summarizes different types DNA, histones, RNA, their known regulators. We also discuss how epigenetic change during process by which proteins control assess translational potential. The stem cells highlighted. In addition, we propose alternative splicing interacts regulate mass, offering novel perspective enhances our understanding inheritance’s network governing atrophy. Collectively, advancements provide invaluable insights into study Moreover, knowledge paves way for identifying new avenues development more strategies pharmaceutical interventions.
