PCa tends to spread to bones and acquire the bone-like phenotype, causing osteoblastic bone metastasis. Unfortunately, there is no effective treatment for this condition. However, melatonin, which regulates our circadian rhythm, has been found to have anti-tumor properties. It has yet to be established whether it is effective in treating osteoblastic PCa metastasis. Our findings show that melatonin inhibits the production of endothelin-1 (ET-1) in osteoblastic PCa cells, suppressing osteoblast differentiation. Clinical results indicate that bone metastatic PCa patients have higher levels of ET-1 compared to nonmetastatic PCa patients. Furthermore, melatonin-induced miR-let-7f-5p inhibits ET-1-promoted osteoblast differentiation in osteoblastic PCa. Melatonin also suppresses the property of osteomimicry in osteoblastic PCa cells. Importantly, in the intratibia injection PCa metastasis model, melatonin decreased osteoblastic PCa tumor growth, inhibiting ET-1 production and osteoblast differentiation in vivo. Taken together, melatonin inhibits osteoblastic PCa-regulated osteoblastogenesis by reducing ET-1 production through upregulation of miR-let-7f-5p, while suppressing the property of osteomimicry in osteoblastic PCa.

Normal sleep consists of an orderly progression through wakefulness, non-rapid eye movement (NREM) sleep, and rapid eye movement (REM) sleep, all of which are tightly regulated. Melatonin, often referred to as the “hormone of sleep,” plays a pivotal role as a regulator of the sleep/wake cycle and exerts its effects through high-affinity G-protein coupled receptors known as MT1 and MT2. Selective modulation of these receptors presents a promising therapeutic avenue for sleep disorders. This review examines research on the multifaceted role of melatonin in sleep regulation, focusing on selective ligands targeting MT1 and MT2 receptors, as well as studies involving MT1 and MT2 knockout mice. Contrary to common beliefs, growing evidence suggests that melatonin, through MT1 and MT2 receptors, might not only influence circadian aspects of sleep but likely, also modulate the homeostatic process of sleep and sleep architecture, or could be the molecule linking the homeostatic and circadian regulation of sleep. Furthermore, the distinct brain localization of MT1 and MT2 receptors, with MT1 receptors primarily regulating REM sleep and MT2 receptors regulating NREM sleep, is discussed. Collectively, sleep regulation extends beyond the circulating levels and circadian peak of melatonin; it also critically involves the expression, molecular activation, and regulatory functions of MT1 and MT2 receptors across various brain regions and nuclei involved in the regulation of sleep. This research underscores the importance of ongoing investigation into the selective roles of MT1 and MT2 receptors in sleep. Such research efforts are expected to pave the way for the development of targeted MT1 or MT2 receptors ligands, thereby optimizing therapeutic interventions for sleep disorders.</p>","PeriodicalId":198,"journal":{"name":"Journal of Pineal Research","volume":"76 7","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jpi.13011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142435646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we introduce the concepts of “L-shift” (longer light phase on the shift day) and “D-shift” (longer dark phase), and investigate how these variations impact the adaptability of mice to jet lag. By examining multiple phase shifts (12L vs. 12D, +6L vs. +6D, −6L vs. −6D), we demonstrate that L-shifts not only facilitate faster adaptation but also significantly reduce the severity of sepsis in a jet lag-sensitive lipopolysaccharide-induced sepsis model. Further investigations with additional phase shifts at 1-h intervals (+8 to +11) reinforced the enhanced fitness of mice under L-shifts. Mechanistically, L-shifts were found to increase sleep duration, thereby improving circadian entrainment, with sleep deprivation nullifying the adaptability differences between lighting protocols.

We used initially bioinformatics results to show that melatonin regulated significantly the correlation between pro-inflammation and myogenesis in RA synovial fibroblasts (RASF) and myoblasts. The conditioned medium (CM) from melatonin-treated RASF was incubated in myoblasts with growth medium and differentiated medium to investigate the markers of pro-inflammation, atrophy, and myogenesis.

Melatonin is a well-recognized antioxidant and an anti-inflammatory agent that benefits multiple organs. However, the beneficial effects of melatonin on gut leakiness–associated liver fibrosis have not been systemically studied. Here, we investigated the protective mechanisms of melatonin against thioacetamide (TAA)–induced gut barrier dysfunction and hepatic fibrosis by focusing on posttranslational protein modifications through the gut–liver axis. Our results showed that gut leakiness markers, including decreased gut tight/adherens junction proteins (TJ/AJs) with increased intestinal deformation, apoptosis, and serum endotoxin, were observed early at 1 week after TAA exposure. Liver injury, apoptosis, and fibrosis were prominent at 2 and 4 weeks. Mechanistically, we found that gut TJ/AJs were hyper-acetylated, followed by ubiquitin-dependent proteolysis, leading to their degradation and gut leakiness. Gut dysbiosis, hepatic protein hyper-acetylation, and SIRT1 downregulation were also observed. Consistently, intestinal <i>Sirt1</i> deficiency greatly enhanced protein hyper-acetylation, gut leakiness, endotoxemia, and liver fibrosis. Pretreatment with melatonin prevented or improved all these changes in both the gut and liver. Furthermore, melatonin blunted protein acetylation and injury in TAA–exposed T84 human intestinal and AML12 mouse liver cells. Overall, this study demonstrated novel mechanisms by which melatonin prevents gut leakiness and liver fibrosis through the gut–liver axis by attenuating the acetylation of intestinal and hepatic proteins. Thus, melatonin consumption can become a potentially safe supplement for liver fibrosis patients by preventing protein hyper-acetylation and gut leakiness.</p>","PeriodicalId":198,"journal":{"name":"Journal of Pineal Research","volume":"76 6","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jpi.13007","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142230950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to demonstrate the existence of ferroptosis in osteoarthritis and explore the specific mechanism of melatonin in suppressing ferroptosis and alleviating osteoarthritis. Our findings reveal that melatonin reverses inflammation-induced oxidative stress and lipid peroxidation while promoting the expression of extracellular matrix components in chondrocytes, safeguarding the cells. Our research has revealed that NADPH oxidase 4 (NOX4) serves as a crucial molecule in the ferroptosis process of osteoarthritis. Specifically, NOX4 is located on mitochondria in chondrocytes, which can induce disorders in mitochondrial energy metabolism and dysfunction, thereby intensifying oxidative stress and lipid peroxidation. LC-MS analysis further uncovered that GRP78 is a downstream binding protein of NOX4. NOX4 induces ferroptosis by weakening GRP78's protective effect on GPX4 and reducing its expression. Melatonin can inhibit the upregulation of NOX4 on mitochondria and mitigate mitochondrial dysfunction, effectively suppressing ferroptosis and alleviating osteoarthritis.
