- Accelerated cellular senescence may be a key process in the progression of periodontitis, as it integrates the devastating effects of the major risk factors for periodontitis. Circadian rhythm disruption (CRD) affects the expression levels of multiple genes, such as brain and muscle ARNT-Like-1 (BMAL1), which is thought to be an important trigger or exacerbator of periodontitis. Even though CRD mechanisms are acknowledged to control cellular senescence, their effect on the senescence that happens during periodontitis is not well defined. This research aimed to explore the role and pathogenic mechanism of CRD in periodontitis and the involvement of cellular senescence, with the purpose of providing innovative ideas for the prevention and treatment of periodontitis. A rat model combining CRD and periodontitis was established. Periodontal lesions were assessed via histological staining. The expression levels of core circadian genes and senescence markers were evaluated. Inflammatory mediators related to the senescence-associated secretory phenotype (SASP) were quantified. The BMAL1 agonist SR8278 was employed to verify the key role of BMAL1 and the BMAL1/cryptochrome 2 (CRY2)/period circadian regulator 1 (PER1) signaling pathway. Finally, the effect of BMAL1 modulation on cellular senescence was examined in lipopolysaccharide (LPS)-induced human periodontal ligament cells (hPDLCs). CRD exacerbated experimental periodontitis lesions and aggravated the periodontal tissue senescence phenotype. BMAL1/CRY2/PER1 gene levels were down-regulated in a model of CRD-complexed periodontitis, and restoration of BMAL1 levels could alleviate CRD-exacerbated periodontitis by attenuating the periodontal tissue senescence phenotype. Interestingly, LPS exposure resulted in increased cellular senescence and decreased BMAL1/CRY2/PER1 in hPDLCs. Knockdown of BMAL1 resulted in further upregulation of cellular senescence in hPDLCs, whereas overexpression of BMAL1 inhibited LPS-induced cellular senescence. This study establishes a significant link between CRD and the aggravation of experimental periodontitis, within which a dysregulated BMAL1/CRY2/PER1 axis and an enhanced senescence phenotype are prominent features. This perspective opens new avenues for periodontitis intervention by focusing on circadian rhythm modulation. - Source: PubMed

Zheng ChaoHuiLi YuanYuanZhang YanLiGeng TaoZhou ZiLingJin BeiFangWang LuPing - Following extensive liver resections, diminished liver regeneration impairs the maintenance or restoration of sufficient functional liver mass. Currently, effective therapies to restore liver regeneration are lacking, rendering liver transplantation the sole treatment option for end-stage liver disease. Therefore, it is imperative to elucidate the regulatory mechanisms underlying liver regeneration. In this study, we employed a multi-omics approach integrating Hi-C, RNA-seq, and ATAC-seq to dissect the early regulatory mechanisms of liver regeneration in rats and mice. Our results indicate that immune and inflammatory processes are markedly enriched during the early phase of regeneration, accompanied by upregulation of glucocorticoids (GCs) and their receptor (GR). First, the expression dynamics of the GC-related circadian gene Nr1d1 and its regulatory network-including Nfκbiα, Arntl, Clock, and Rora-align with chromatin reorganization, leading us to propose that the GC-GR-Nr1d1 axis is involved in maintaining liver homeostasis. Second, the GR-regulated FoxO family is significantly enriched, and the FoxO-associated gene Klf2 exhibits coordinated changes in expression, chromatin accessibility, and chromatin structure. Functional experiments demonstrate that Klf2 negatively regulates hepatocyte proliferation. Hence, we propose the GC-GR-FoxOs-Klf2 axis acts as a checkpoint in hepatocyte proliferation, preventing premature activation of proliferation- and cell cycle-related genes and ensuring orderly and efficient liver regeneration. Our findings on the role of GCs in liver regeneration may further support their future therapeutic application in liver diseases such as liver fibrosis, alcoholic cirrhosis, and hepatocellular carcinoma (HCC). - Source: PubMed

Ye BingyuXie DejianShen WenlongYue MeijuanJin QinpengGuo XinjieZhang YanLi PingZhao Zhihu - Research to date describes the suprachiasmatic nucleus (SCN) of the hypothalamus as the master pacemaker that synchronizes circadian rhythms in peripheral tissues. However, recent high-impact studies demonstrate that non-SCN tissues can also coordinate rhythms in other peripheral tissues. However, the extent to which the cardiac clock regulates peripheral clocks has not yet been tested. Therefore, we investigated the role of the cardiac clock in modulating extra-cardiac circadian function using a model of cardiac-specific deletion of the core clock protein Bmal1 (Bmal1 cKO). Bmal1 cKO mice demonstrated attenuated day-night differences in skeletal muscle core clock gene expression (Bmal1, Clock, Per1) and circadian expressed metabolic genes (Pdk4, Ppara) as well as impaired day-night muscle grip strength. In the kidney, Bmal1 cKO mice had blunted core clock gene and water balance gene expression (Avp) compared to WT mice. Proteomic analysis of serum identified fibulin 5 (Fbln5) as a potential cardiokine mediating peripheral circadian effects, with rhythmic expression of Fbln5 disrupted in the heart and serum of Bmal1 cKO mice compared to WT. Exogenous treatment of synchronized C2C12 myotubes and human renal cells with rFbln5 disrupted rhythmic clock gene expression. In vivo, supplementation of Fbln5 in the drinking water of healthy wildtype C57Bl6 mice also disrupted kidney muscle rhythms. RNA sequencing data suggested that Fbln5 alters circadian output programs via stress-activated mechanotransduction and metabolic remodeling. Importantly, these changes occur without overt SCN dysfunction. Together, we demonstrate a critical role for the heart in regulating peripheral circadian control through the novel circadian cardiokine Fbln5. - Source: PubMed
Bettadapura Sharanya STangeman David CSatyanarayana Sushumna BRuhmann Madison MBonds Willa JEdwards J HarrisonGupta PoojaYusifov AykhanTodd William DBruns Danielle R - Background / HypothesisHeadache attacks are reported to occur with circadian rhythmicity by 2/3 of individuals with cluster headache, hinting to potential dysfunctions of the molecular clock. The aim of this study was to investigate the contribution of genetic markers in core clock genes, alone or in combinations, to the genetic risk for cluster headache.MethodsSeven markers in core clock genes and were genotyped using TaqMan qPCR in 707 individuals with cluster headache and 682 controls. Genetic data from eleven additional markers located in six other core clock genes (, , and ) was obtained from the database of the Centre for Cluster Headache at Karolinska Institutet. Genotype analysis was applied for risk analysis for combinations of up to three markers. For validation we used a cluster headache cohort from the National Hospital for Neurology and Neurosurgery, London, UK.Results and interpretationSingle marker analysis of the newly genotyped markers in and found rs3789327 and rs3768984 more frequently among individuals with cluster headache (p < 0.01 and p < 0.05 respectively). Multiallelic analysis revealed that the median number of risk alleles was eight for controls and nine for individuals with cluster headache, which justifies the analysis of combinations of markers. The analysis of combinations of up to three markers identified 258 out of 897 combinations to be associated with significant risk. Further investigation starting from the function of genes in the molecular clock transcription-translation feedback loop (TTFL) found that 80% of the combinations had >50% markers located in the positive arm of the TTFL. The comparison between Swedish and UK cohorts identified 39 concordant combinations, which confirmed the risk associated with rs3768984 (), as well as the enrichment in markers in , , and in combinations associated with significant risk.ConclusionOur data points to molecular clock dysfunction playing a central role in the manifestation of cluster headache. - Source: PubMed

Rotenone is also administered to rats to induce nigrostriatal dopaminergic neuron loss in an established model of Parkinson’s Disease (PD). However, the molecular mechanisms linking rotenone action to the emergence of PD-like phenotypes are poorly understood. Here, we characterize rotenone-induced gene dysregulation in the striatum. Male Lewis rats at 12–14 months received rotenone injected at 3 mg/kg, i.p. once daily for nine days. Behavioral effects of rotenone were verified using the bar test for catalepsy. RNA sequencing was carried out on RNA extracted from the striatum of rats receiving the full course of Rotenone treatment and vehicle-treated controls. Illumina PE150 sequencing to 30 M clusters per sample revealed several hundred differentially expressed genes (DEGs) at FDR < 5%. These included Dopa decarboxylase (), which encodes an important enzyme in dopamine production, and Angiopoietin 2 (), a gene previously implicated in analysis of post-mortem PD brain. Pathway analysis of top findings identified the Circadian Clock System as enriched with rotenone DEGs. Circadian and sleep dysfunction is a known feature of PD. We validated the differential expression of two circadian genes via quantitative PCR: downregulation of Period 3 () and upregulation of the aryl hydrocarbon receptor nuclear translocator-like (). Overall this study represents a first look at striatal dysregulation of gene expression in the established rotenone PD model and indicates that further study of circadian gene dysregulation in this model may be fruitful. - Source: PubMed
