Qidan Yixin decoction (QDYXD) demonstrated encouraging clinical results in treating DCM; however, its underlying mechanics are yet unclear. <b>Methods:</b> Network pharmacology was applied to determine the active ingredients and targets of QDYXD. The GeneCards and GEO databases were used to retrieve genes associated with DCM and macrophage polarization. These targets were subjected to GO and KEGG enrichment analyses, immune infiltration study, and PPI network design. The core targets were further refined using SVM-RFE, LASSO, and random forest algorithms. Docking the core targets with the main active components followed. For experimental validation, rat models were created. <b>Results:</b> There were 48 potential targets in all. Quercetin, methyl palmitate, luteolin, and tanshinone IIA were identified as the primary active components. Enrichment analysis indicated that one of the key pathways associated with the potential targets was the signaling pathway of HIF-1. Machine learning techniques were used to identify two core targets, LDHA and PGK1. Animal experiments demonstrated that QDYXD can suppress the upregulation of PGK1, LDHA, and HIF1A; block the polarization of M1 macrophages; and considerably enhance DCM rats' cardiac function. <b>Conclusion:</b> QDYXD improves cardiac function in DCM by attenuating M1 macrophage polarization and inhibiting the HIF-1 signaling pathway, specifically through the modulation of PGK1, LDHA, and HIF1A. This study provides preliminary insights into how QDYXD modulates macrophage polarization during DCM treatment. Moreover, the identification of potential active components and core molecular targets of QDYXD offers promising directions for future drug development in DCM therapy.</p>","PeriodicalId":15576,"journal":{"name":"Journal of Diabetes Research","volume":"2025 ","pages":"7578626"},"PeriodicalIF":3.4,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12331402/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144799272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data on exposures including ferritin, serum iron, transferrin saturation (TSAT), and total iron-binding capacity (TIBC) were obtained from a genome-wide association study (GWAS). The outcomes were diabetic nephropathy, Type 1 diabetes mellitus (T1DM) with renal complications, Type 2 diabetes mellitus (T2DM) with renal complications, estimated glomerular filtration rate (creatinine) (eGFRcrea) in diabetes mellitus, and urinary albumin-to-creatinine ratio (UACR) in diabetes mellitus. The causal associations of exposures and outcomes were analyzed using MR analysis with the inverse variance-weighted (IVW) method as the primary analytical method. Leave-one-out analysis was utilized to find any individual SNP associated with exposures influencing outcomes. Odds ratio (OR) and 95% confidence interval (95% CI) were estimated. The <i>F</i> values of all the SNPs were > 10, indicating a sufficient strength of the instrumental variables. The results from pleiotropy analysis indicated that most SNPs showed no horizontal pleiotropy (<i>p</i> > 0.05). The ferritin level had a causal effect on decreased eGFRcrea level in diabetes mellitus patients (OR = 0.937, 95% CI: 0.887-0.990) and increased risk of T1DM with renal complications (OR = 1.783, 95% CI: 1.005-3.162).

Ferritin level had a causal effect on eGFRcrea level in diabetes mellitus patients and T1DM with renal complications. In conclusion, TIBC levels are causally linked to a lower risk of both diabetic nephropathy and T1DM with renal complications.

Research has increasingly focused on kidney injury resulting from lipid metabolism disorders. Adipose triglyceride lipase (ATGL), a pivotal enzyme in lipolysis, is essential for maintaining lipid metabolism balance. The objective of this study was to assess whether serum ATGL could serve as an early biomarker for DKD. <b>Methods:</b> The study divided 236 participants into four groups: healthy controls (<i>n</i> = 59), Type 2 diabetes mellitus (T2DM) with albumin-to-creatinine ratio (ACR) < 30 mg/g (<i>n</i> = 80), microalbuminuria (L-DKD) with ACR 30-300 mg/g (<i>n</i> = 41), and macroalbuminuria (H-DKD) with ACR ≥ 300 mg/g (<i>n</i> = 56). Relevant clinical data were collected, and serum levels of ATGL, kidney injury molecule-1 (KIM-1), and tumor necrosis factor-1 (TNFR-1) were measured. Various statistical analyses, including Spearman's correlation test, receiver operating characteristic curve analysis, multivariate logistic regression, and restricted cubic spline (RCS), were employed to assess the relationship between serum ATGL levels and renal function impairment in DKD. <b>Results:</b> Serum ATGL levels were notably lower in the T2DM, L-DKD, and H-DKD groups compared to healthy controls. Positive correlations were found between serum ATGL levels and estimated glomerular filtration rates (eGFR), while negative correlations were observed with diabetes duration, hypertension history, hyperlipidemia, urine ACR (UACR), 24-h urine total protein (UTP), serum creatinine (SCr), blood urea nitrogen, uric acid, TNFR-1, and KIM-1/creatinine (KIM-1/Cr) levels (<i>p</i> < 0.05). The receiver operating characteristic curve analysis demonstrated that the diagnostic performance of ATGL, when combined with traditional clinical markers, can enhance sensitivity. When participants were grouped by serum ATGL quartiles, it was observed that higher ATGL levels corresponded with lower UACR, 24 h-UTP, SCr, and TNFR-1 levels and higher eGFR. The odds ratios for elevated UACR and 24 h-UTP decreased, and eGFR increased with higher ATGL quartiles. Both univariate and multivariate logistic regression analyses indicated that serum ATGL is a protective factor against DKD development, even after adjusting for potential confounders. RCS analysis indicated a nonlinear dose-response association between serum ATGL levels and renal function metrics, specifically UACR and eGFR, in patients with DKD. <b>Conclusion:</b> Serum ATGL levels are linked to reduced renal function in T2DM patients.

The study employed network pharmacology to identify potential targets of NaP for Type 2 diabetes treatment, using oleic acid (OA) and advanced glycation end products (AGEs) to induce diabetic liver injury in HepG2 cells <i>in vitro</i>. Post-NaP intervention, Oil Red O staining assessed cellular lipid deposition, while Western blotting analyzed protein expression associated with oxidative stress, autophagy, and bile acid synthesis. NaP was administered to mice with diabetic liver injury induced by a high-fat and AGEs diet, and qPCR analysis was conducted to assess the expression of genes associated with inflammation, oxidative stress, and bile acid synthesis in the liver. HE staining was used to observe the liver injury, and nontargeted metabolomics analysis was used to analyze the effect of NaP on serum metabolic pathways. Network pharmacology analysis showed that NaP has anti-inflammatory and antioxidant effects, mainly involving multiple targets such as mitochondrial function, insulin resistance, and glucose metabolism. Experimental results in cells and animals demonstrated that NaP reduces lipid accumulation and inflammation in liver cells; decreases inflammatory markers like NLRP3, IL-1<i>β</i>, and TNF-<i>α</i>; enhances antioxidant factors such as serum SOD and liver Nrf2; increases the expression of the bile acid synthesis enzyme CYP7A1; and upregulates autophagy in liver cells. Serum nontargeted metabolomics indicated that NaP enhances anti-inflammatory and antioxidant metabolites, including proline and N-Acetyl-L-leucine, in diabetic liver injury mice. It potentially influences purine metabolism, amino acid synthesis (e.g., arginine, tryptophan, and tyrosine), and steroid hormone biosynthesis. This study indicates that NaP may serve as a preventive and therapeutic agent for diabetic liver injury.</p>","PeriodicalId":15576,"journal":{"name":"Journal of Diabetes Research","volume":"2025 ","pages":"3955893"},"PeriodicalIF":3.6,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12240661/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144600634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
