Insulin-like growth factor-binding protein 7 (IGFBP7) is not only a biomarker of acute kidney injury (AKI), but also plays a functional role in promoting kidney injury and inflammation. Abnormal repair of AKI causes kidney fibrosis and chronic kidney disease. IGFBP7 has also been reported as a more sensitive biomarker for liver fibrosis. However, its role in hepatorenal fibrosis requires further investigation.METHODSIGFBP7 global and conditional knockout mice were used to determine the role of IGFBP7 in cadmium-induced hepatorenal fibrosis. Then, liquid chromatography-mass spectrometry, truncated mutants, co-immunoprecipitation, and microscale thermophoresis were employed to unravel the downstream mechanisms.RESULTSIGFBP7 expression was significantly elevated in kidney and liver tissues of mice subjected to chronic cadmium exposure. IGFBP7 deficiency attenuated cadmium-induced hepatorenal dysfunction and fibrosis, whereas restoration of IGFBP7 expression in IGFBP7-deficient mice reproduced hepatorenal fibrosis. Mechanistically, IGFBP7 interacted with alpha-enolase (ENO1) and inhibited its ubiquitination and degradation. Upregulated ENO1 further promoted glucose metabolic reprogramming and lactate accumulation. Conversely, lactate accumulation enhanced IGFBP7 transcription and expression through histone H3K18 lactylation. Importantly, therapy targeting IGFBP7 significantly ameliorated cadmium-induced hepatorenal fibrosis.CONCLUSIONSIGFBP7 promoted cadmium-induced hepatorenal fibrosis by enhancing ENO1-driven abnormal glycolysis and lactate accumulation.","PeriodicalId":17217,"journal":{"name":"Journal of The American Society of Nephrology","volume":"10 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143819376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clonal hematopoiesis of indeterminate potential (CHIP) has been associated with cardiovascular disease in the general population, with a causal role observed in animal models. In the general population, the effect of CHIP is greater for somatic mutations in pre-defined CHIP driver genes other than DNMT3A (referred to as non-DNMT3A CHIP). We sought to assess the prospective association between CHIP and cardiovascular events in patients with CKD.METHODSCHIP was measured by high-depth targeted sequencing. The primary analysis tested the association of somatic mutations in non-DNMT3A CHIP driver genes with a composite cardiovascular disease endpoint of myocardial infarction, stroke, congestive heart failure, and peripheral artery disease in 5,043 patients with CKD in four prospective cohorts. Sensitivity analyses examined the effect of CHIP subtypes, race, baseline comorbidities, APOL1 risk alleles, and IL6R p.Asp358Ala genotype.RESULTSAt baseline, patients had a mean age of 66 ± 12 years and eGFR of 43 ± 18 ml/min/1.73m2. CHIP was present in 24% of patients, with 13% of all patients carrying acquired non-DNMT3A mutations. Non-DNMT3A CHIP was associated with a 36% higher risk of the composite cardiovascular endpoint [95% confidence interval (CI), 6% - 76%]. Among composite components, non-DNMT3A CHIP was associated with a higher risk of stroke (HR 1.65; 95% CI 1.10 - 2.47). Baseline eGFR, diabetes status, or race did not alter the association of non-DNMT3A CHIP with cardiovascular risk.

Prior studies of CHIP in individuals with CKD had limited sample sizes and conflicting findings.METHODSWe examined CHIP and CKD progression in four CKD cohorts (N = 5,654): the Chronic Renal Insufficiency Cohort (CRIC), the African American Study of Kidney Disease (AASK), individuals with CKD from the BioVU biorepository, and the Canadian study of prediction of death, dialysis and interim cardiovascular events (CanPREDDICT).Primary outcomes were incident CKD progression (50% eGFR decline or kidney failure), and eGFR slope over time.

There is wide variation in current volume-related practices between dialysis units and an urgent need to develop better evidence to guide practice. Clinical decisions relating to volume management are implicitly based on assessment of volume status, and there are numerous different but imperfect methods of assessment. Isotope-based dilutions are impractical for clinical use and may not be a gold-standard for patients with kidney failure. Individual trends in body weight and blood pressure have been used as a pragmatic surrogate marker for volume status. Probing the target weight based on blood pressure is still widely practiced but may pose risks related to volume depletion and accelerated loss of residual kidney function. Clinical signs such as elevated jugular venous pressure and leg edema are readily accessible but have poor diagnostic accuracy and wide interobserver variability that limit their reproducibility for volume assessment in clinical trials. Lung ultrasound and bioelectrical impedance analysis have a sound scientific rationale for the assessment of extracellular volume, and are appropriately associated with clinical outcomes, but neither approach has demonstrated convincingly favorable clinical outcomes in clinical trials. Other technologies for volume assessment exist but require further assessment in clinical trials. Advancements in clinical care can be made with existing technologies through comparative effectiveness trials of different fluid management strategies, routine and standardized measurement of volumetric parameters and individual patient preferences, and innovative integration of existing volume assessment methods.

Late death-censored graft loss typically results from a combination of immune and nonimmune events leading to common nonspecific endpoints (e.g., tubular atrophy, interstitial fibrosis and glomerulosclerosis). Conversely, leading causes of death with graft function typically include cardiovascular events, malignancy, and infection. With an improved understanding of the multiple mechanism by which late graft dysfunction develops, there is an opportunity to identify patients at greatest risk and institute novel strategies to quell the process. Newer cardiometabolic agents with proven benefit in the general population have not been well-studied in kidney transplant recipients. However, in addition to their potential benefits in terms of reducing cardiovascular, infectious and malignancy endpoints (thus minimizing death with graft function risk), many novel agents may have additional anti-inflammatory and/or anti-fibrotic benefit (minimizing death-censored graft loss risk) in the kidney transplant population. In this review, we summarize existing literature regarding major causes of death-censored graft loss and death with graft function, and discuss the potential roles of new cardio-renal metabolic agents including sodium-glucose cotransport 2 inhibitors (SGLT2i), non-steroidal mineralocorticoid receptor antagonists (MRA), glucagon-like peptide 1 receptor agonists (GLP1-RA), and dual endothelin and angiotensin receptor antagonists in the kidney transplant population, including potential mechanisms to improve death with graft function and death-censored graft loss outcomes.</p>","PeriodicalId":17217,"journal":{"name":"Journal of The American Society of Nephrology","volume":" ","pages":""},"PeriodicalIF":10.3,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143795945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
