Analyses of previously reported transcriptomic data revealed increased expression of Titin-cap (Tcap) in adult compared to embryonic myocytes and identified myosin light chain 2 (Myl2) as clock-controlled. Given cardiac sarcomeric roles of the encoded proteins, we hypothesized that extracellular cues driving postnatal cardiac maturation and hypertrophy influence time-of-day Tcap and Myl2 expression. Tcap induction was concomitant with neonatal myocyte binucleation, fetal gene suppression, and increased heart weight during the early phase of cardiac growth. Since norepinephrine stimulates β-adrenergic and α-adrenergic receptors, the latter driving clock-controlled transcriptional remodeling, phase‑response curves of the β‑adrenergic agonist isoproterenol (ISO) following α-adrenergic stimulation with phenylephrine (PE) were performed on neonatal rat ventricular myocytes (NRVM), revealing periodic myocyte hypertrophy and TCAP protein expression. PE entrenched ISO-mediated Tcap suppression, to which oscillatory Per2 and Myl2 transcription was impervious. Differential NRVM culture density revealed biomass-dependent changes in Per2 and Tcap transcription and hypertrophy timing. Hypoxia initiated myocyte atrophy and Bmal1-dependent Tcap transcription, reflected in decreased heart weight and increased Tcap expression in hypoxic neonatal rat hearts. Tcap depletion impaired Bmal1 and fetal hypertrophic gene expression, compromised hypoxia-mediated Myl2 transcriptional suppression, and aggravated hypoxia-induced atrophy. In summary, Tcap and Myl2 are circadian genes differentially influenced by environmental factors, including adrenergic stimulation, paracrine signaling, and O<sub>2</sub> tension during postnatal cardiac maturation. These findings have implications for the distinct regulation of myocyte growth and maturation, by external cues during the postnatal period.</p>","PeriodicalId":11767,"journal":{"name":"Epigenetics","volume":"21 1","pages":"2694794"},"PeriodicalIF":3.7,"publicationDate":"2026-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13393232/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148548202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how oncogenic signaling pathways interface with the DNA methylation machinery remains poorly understood. In this study, we identify AURKA as a key regulator of global DNA methylation in PCa cells. AURKA depletion markedly reduces genomic 5-methylcytosine (5mC) levels, indicating its essential role in DNA methylation maintenance. Mechanistically, AURKA directly interacts with UHRF1-a crucial epigenetic regulator that recruits DNMT1 to hemimethylated DNA, and phosphorylates it at Ser76, thereby enhancing UHRF1 protein stability. AURKA depletion accelerates UHRF1 degradation via the ubiquitin-proteasome pathway, whereas AURKA overexpression stabilizes UHRF1 by suppressing its polyubiquitination. The phospho-deficient UHRF1 S76A mutant exhibits reduced stability and increased polyubiquitination, confirming that phosphorylation at Ser76 is critical for AURKA-mediated UHRF1 stabilization. Functionally, disruption of the AURKA-UHRF1 axis de-represses <i>p16</i> and <i>p21</i> and significantly impairs PCa cell proliferation; these effects are contingent upon UHRF1 phosphorylation, as only wild-type UHRF1, not the phospho-deficient S76A mutant, can rescue the observed phenotypic impairments. Collectively, our study reveals a previously unrecognized AURKA-UHRF1 signaling axis that links kinase activity to epigenetic maintenance. By phosphorylating UHRF1 at Ser76 and stabilizing its protein, AURKA sustains global DNA methylation and promotes PCa cell proliferation.

It is often achieved by monoallelic 5-methylcytosine, resulting in the formation of differentially methylated regions (DMRs). These show a bias towards oocyte-derived methylation and survive reprogramming in the pre-implantation embryo. Imprinting is widespread in the human placenta. We have recently performed whole-genome screens for novel imprinted placenta-specific germline DMRs (gDMRs) by comparing methylomes of gametes, blastocysts and various somatic tissues, including placenta. We observe that, unlike conventional imprinting, for which methylation at gDMRs is observed in all tissues, placenta-specific imprinting is associated with transient gDMRs, present only in the pre-implantation embryo and extra-embryonic lineages. To expand the list of <i>bona fide</i> imprinted genes subject to placenta-specific imprinting, we reinvestigated our list of candidate loci and characterized two novel imprinted genes, <i>PIK3R1</i> and <i>G0S2</i>, both of which display polymorphic imprinting. Interrogation of placenta single-cell RNA-seq datasets, as well as cell-type methylation profiles, revealed complex cell-type specificity. We further interrogated their methylation and expression in placental samples from complicated pregnancies, but failed to identify differences between intrauterine growth restricted or pre-eclamptic samples and controls, suggesting they are not involved in these conditions.</p>","PeriodicalId":11767,"journal":{"name":"Epigenetics","volume":"20 1","pages":"2523191"},"PeriodicalIF":2.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12203861/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144495310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
