Reducing environmental factors linked to hypertension in children is necessary to prevent hypertension in adults. To investigate the associations between outdoor artificial light at night (ALAN) and blood pressure among children. We recruited 9354 children aged 5-17 in the Seven Northeastern Cities Study between 2012 and 2013. Trained nurses measured their blood pressure with a mercury sphygmomanometer. We defined hypertension as systolic blood pressure (SBP) or diastolic blood pressure (DBP) ≥95th age-sex-height-specific percentile. We geocoded the address of each child and linked it to estimated outdoor ALAN within 500 m (ALAN<sub>-500 m</sub>) sourced from the VIIRS/DNB. We utilized generalized linear mixed-effect models to assess the associations of outdoor ALAN and blood pressure and the odds of hypertension. Effect modification by age, sex, weight status, and other potential factors was also explored. The SBP, DBP, and mean arterial pressure at quartile 4 (Q4) of outdoor ALAN<sub>-500 m</sub> against Q1 increased in 1.45 (95% CI: 0.31-2.59) mmHg, 2.09 (95% CI: 1.18-2.99) mmHg, and 1.87 (95% CI: 0.99-2.76) mmHg, respectively. The odds of hypertension increased by 30% in Q3 of outdoor ALAN<sub>-500 m</sub> compared to Q1 (OR = 1.30, 95% CI: 1.05-1.61). Furthermore, stronger effect estimates were observed among children aged ≤11 years (Q4, β = 5.07[3.28-6.85] vs β = 1.54[0.37-2.71] for DBP) and who were overweight (Q4, OR = 1.95[1.17-3.22] vs OR = 0.89[0.60-1.32] for hypertension). Living in areas with high outdoor ALAN exposure increased the odds of hypertension in children, especially in children aged ≤11 years and overweight.

We previously reported the upregulation of Piezo1 in the glomerular podocytes of hypertensive nephropathy mice in vivo and a mechanical stretch-induced podocyte injury cascade via Piezo1 and Rac1 in vitro, suggesting the pathogenic involvement of Piezo1. However, recent reports on podocyte-specific Piezo1 knockout mice with various podocyte injury models other than hypertension have yielded inconsistent results, indicating pathogenic and anti-pathogenic roles of Piezo1. In this study, we generated podocyte-specific Piezo1 knockout mice and examined their podocyte phenotypes under normotensive and hypertensive conditions induced by angiotensin II and a high-salt diet. Podocyte-specific Piezo1 knockout mice did not spontaneously develop podocyte injury. Angiotensin II infusion and a high-salt diet for 14 days caused hypertension, but not significant podocyte injury and proteinuria in the littermate control mice, which were strengthened by podocyte-specific Piezo1 deletion. Through comprehensive transcriptome analysis of the glomeruli of wild-type and podocyte-specific Piezo1 knockout mice, we found altered expression of several genes, including Rhpn1 encoding Rho GTPase binding protein Rhophilin1. Podocyte injury in hypertensive podocyte-specific Piezo1 knockout mice was inhibited by the angiotensin II receptor blocker losartan, the anti-hypertensive drug hydralazine, and partially ameliorated by the Rho kinase inhibitor fasudil, suggesting that podocyte injury in the knockout mice may be mediated by Rhophilin1 and/or Rho signaling downstream of Piezo1. Findings related to the hypertensive podocyte injury model support the possible anti-pathogenic protective roles of Piezo1. We created podocyte-specific Piezo1 KO mice, and hypertension was induced by angiotensin II and a high-salt diet. Hypertension-evoked proteinuria and podocyte injury were exaggerated in the KO mice. They were ameliorated by anti-hypertensive drugs and Rho kinase inhibitor, suggesting protective roles of Piezo1 and involvement of RhoA signaling.</p>","PeriodicalId":13029,"journal":{"name":"Hypertension Research","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145212535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study included patients with fluid retention, defined by an extracellular water to total body water (ECW/TBW) ratio > 0.400, as measured by bioimpedance analysis. We evaluated 6-month changes in body fluid status and serum copeptin levels, a surrogate marker for vasopressin, between two groups: patients receiving SGLT2 inhibitor dapagliflozin monotherapy (SGLT2i group, n = 13; estimated glomerular filtration rate [eGFR] 25.0 ± 8.5 mL/min/1.73 m<sup>2</sup>) and those receiving dapagliflozin in combination with loop or thiazide diuretics (SGLT2i + diuretic group, n = 18; eGFR 29.8 ± 15.2 mL/min/1.73 m<sup>2</sup>). Changes in systolic blood pressure and estimated plasma volume did not significantly differ between groups. However, reductions in ECW/TBW, TBW, and interstitial fluid were significantly greater in the combination group than in the monotherapy group. Moreover, the increase in serum copeptin was significantly suppressed in the SGLT2i + diuretic group. No significant intergroup differences were observed in renin and aldosterone changes.
