Abstract The accumulation of lactate is a rising risk factor for patients after flap transplantation. Endothelial‐to‐mesenchymal transition (EndoMT) plays critical role in skin fibrosis. Nevertheless, whether overproduction directly contributes to necrosis and its mechanism remain unknown. current study reveals that mice exhibit enhanced PKM2 fibrotic response. Endothelial‐specific deletion attenuates ameliorates fibrosis mice. Administration or overexpressing promotes dysfunction endothelial cells stimulates mesenchymal‐like phenotype following hypoxia. Mechanistically, glycolytic‐lactate induces correlation between Twist1 p300/CBP, leading lactylation lysine 150 (K150la). increase K150la phosphorylation nuclear translocation further regulates the transcription TGFB1 , hence inducing phenotype. Genetically endothelial‐specific diminishes lactylation, then EndoMT‐associated ischemia. serum levels transplantation are elevated predictive value prognosis. This findings suggested novel PKM2‐derived mediating exacerbates Inhibition reduces response might become potential therapeutic strategy

However, the of lactylation metabolic center, hypothalamus, is still unknown. Here, we show that hypothalamic pro-opiomelanocortin (POMC) neuron-specific deletion family with sequence similarity 172, member A (Fam172a) can increase and protect mice against diet-induced obesity (DIO) related disorders. Conversely, overexpression Fam172a POMC neurons led to an obesity-like phenotype. Using RNA-seq CUT&Tag chromatin profiling analyzes, find knockdown activates glycolytic process increases peptidylglycine α-amidating monooxygenase (PAM), affects synthesis α-MSH, via H4K12la (histone lactylation). In addition, pharmacological inhibition production clearly abrogates anti-obesity effect PFKO (POMC-Cre, Fam172aloxP/loxP, knockout).

Purpose: This study investigates the role of EFEMP1 in choroidal vascular dysfunction and its implications for myopia progression, specifically focusing on FOXO3/VEGFA signaling pathway as a potential therapeutic target. Methods: We utilized adeno-associated virus (AAV) to overexpress knock down choroid guinea pigs. Subsequent proteomic analyses were conducted tissue. used Gene Ontology (GO) Kyoto Encyclopedia Genes Genomes (KEGG) identify relevant pathways genes. In vitro experiments performed RF/6A cells, where both FOXO3 underwent overexpression knockdown. series cell culture experiments, including assessments proliferation, migration, tube formation, sprouting assays, evaluate functional effects EFEMP1. Quantitative reverse transcription PCR Western blot measure gene protein expression levels. Results: Silencing significantly reduced slowed progression myopia. Proteomic analysis demonstrated that regulates activity, resulting increased VEGFA cells promoting angiogenesis. Conversely, knockdown led decreased levels, confirming modulates through FOXO3. Conclusions: Targeting may offer novel strategy prevention treatment by alleviating associated dysregulation. Further exploration could provide additional insights into interventions
