ObjectiveTo identify protein biomarkers and potential therapeutic targets associated with metabolic dysfunction-associated fatty liver disease (MAFLD) through an integrative multi-omics analysis. MethodsLarge-scale plasma protein quantitative trait locus data were integrated with MAFLD genome-wide association study data, and a proteome-wide Mendelian randomization analysis was performed. Summary data-based Mendelian Randomization (SMR)/heterogeneity in dependent instruments (HEIDI) test and colocalization analysis were used to assess significant proteins. The independent samples t-test was used for comparison of continuous data with homogeneity of variance between two groups, and the Welch-corrected t-test was used for comparison of continuous data with heterogeneity of variance. The transcriptomic validation results were compared with the Mendelian randomization results to evaluate the changing trends of gene expression, and boxplots were used to display the expression distribution of candidate genes between groups. ResultsAmong 7 130 proteins analyzed, 40 showed a causal relationship with MAFLD, among which 26 increased the risk of MAFLD and 14 exerted a protective effect against MAFLD (FDR<0.05). Nine proteins were supported by SMR/HEIDI (PSMR<0.05, PHEIDI>0.05), and 14 showed a strong colocalization signal (PPH4>0.9). The transcriptomic analysis identified 5 differentially expressed proteins (all P<0.05), i.e., adenosine diphosphate-ribosylation factor-like GTPase 2, insulin-like growth factor binding protein 2, casein kinase 1 delta (CSNK1D), leucine-rich repeat neuronal 1, and moesin (MSN). In vitro validation showed upregulated expression levels of MSN (1.612±0.346 vs 0.569±0.077, P<0.05), 14-3-3 protein theta (YWHAQ) (1.267±0.126 vs 0.313±0.029, P<0.05), and CSNK1D (0.871±0.025 vs 0.431±0.080, P<0.05) and a downregulated expression level of histone deacetylase 8 (0.637±0.059 vs 1.097±0.260, P<0.05) in the MAFLD cell model. Functional annotation showed that CSNK1D participated in circadian and metabolic regulation, YWHAQ modulated the Hippo pathway and lipid signal transduction, and MSN was associated with cytoskeletal remodeling and fibrogenic responses. ConclusionThe integrative proteogenomic analysis in this study shows that CSNK1D, YWHAQ, and MSN may be key mediators in the pathogenesis of MAFLD. These proteins have the potential to serve as novel biomarkers and therapeutic targets, providing new directions for research on disease mechanisms and the development of intervention strategies.

OBJECTIVE To investigate the mechanism by which resveratrol improves renal injury in rats with uric acid nephropathy (UAN) through inhibition of the protein kinase R-like endoplasmic reticulum kinase (PERK)/eukaryotic translation initiation factor 2α (eIF2α) pathway.METHODS A UAN rat model was established via oral administration of adenine plus potassium oxonate, and the rats were divided into a UAN model group, a positive control group (allopurinol 10 mg/kg), a resveratrol group (100 mg/kg), and a resveratrol+tunicamycin group [resveratrol 100 mg/kg+tunicamycin (PERK activator) 1 mg/kg]. A control group (without modeling) was also established, with 6 rats in each group. Rats in each group were administered the corresponding drug solution and/or normal saline via gavage or intraperitoneal injection once daily for 28 consecutive days. The contents of renal function-related parameters (24-hour urinary total protein, and uric acid, creatinine and blood urea nitrogen in serum), the levels of inflammation-related markers [interleukin-6 (IL-6), IL-18, tumor necrosis factor-α (TNF-α), IL-10, and nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3)], and pathological changes in renal tissue were determined, and the score for tubular damage, the score for inflammatory infiltration, and the degree of mesangial proliferation were assessed. The mRNA expressions of neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1), as well as the expressions of proteins associated with the PERK/eIF2α pathway, were measured in renal tissue from each group.RESULTS Compared with the control group, rats in the UAN model group exhibited marked tubular damage, inflammatory cell infiltration, and mesangial proliferation. The contents of renal function-related parameters, levels of IL-6, IL-18, TNF-α and NLRP3, scores for tubular damage and inflammatory infiltration, degree of mesangial proliferation, mRNA expressions of NGAL and KIM-1, and phosphorylation levels of PERK and eIF2α, as well as the expressions of activating transcription factor 4 and C/EBP homologous protein, were all significantly increased or upregulated, while IL-10 levels were significantly decreased ( P <0.05). Compared with the UAN model group, the resveratrol group and the positive control group showed significant improvements in all of the aforementioned parameters ( P <0.05). Tunicamycin could significantly reverse the beneficial effects of resveratrol on all quantitative parameters ( P <0.05).CONCLUSIONS Resveratrol can reduce inflammatory responses in renal tissue of UAN rats, and improve tubular damage and renal function. These effects may be related to the inhibition of endoplasmic reticulum stress mediated by the PERK/eIF2α pathway.

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by hallmark pathological features, including β-amyloid deposition, neurofibrillary tangles formed by hyperphosphorylated tau protein, and chronic neuroinflammation. Recent studies have revealed that the glymphatic-meningeal-cervical lymphatic system plays a pivotal role in intracranial metabolic waste clearance, and its dysfunction may impair the clearance efficiency of β-amyloid and tau proteins. Based on this mechanism, domestic scholars have innovatively proposed lympho-microsurgical reconstruction of the brain-cervical lymphatic drainage pathway, aiming to ameliorate AD pathological progression and cognitive function by enhancing intracranial waste clearance. Through a comprehensive literature review, this article focuses on the theoretical rationale for lympho-microsurgical intervention in AD. While critically evaluating existing surgical approaches and efficacy assessment systems, it further examines the fundamental scientific challenges and clinical translation barriers in directly applying this technique to AD treatment, with the goal of providing theoretical insights and methodological guidance for future research.

Objective:To explore the influence of initial high-risk cytogenetic abnormalities on the outcomes of children with acute myeloid leukemia (AML) after post-transplant Cyclophosphamide (PTCy)-based allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:A retrospective cohort study.AML children who underwent PTCy-based allo-HSCT after the first complete remission at Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science and Technology between April 2017 and April 2024 were enrolled.Patients were divided into intermediate-risk and high-risk groups based on their initial cytogenetic features.These patients were further divided into complex karyotype, 11q23 rearrangement, and other karyotype groups.Clinical characteristics and survival outcomes were compared among these groups.Measurement and count data were analyzed using Wilcoxon rank-sum/Kruskal-Wallis and χ2 tests, respectively.Survival and risk factor analyses were performed using Kaplan-Meier and Cox proportional hazards methods, respectively. Results:A total of 51 AML children who underwent allo-HSCT were included in this study.The median age at transplantation was 3.2 years and the median follow-up time was 4.6 years.There were 26 cases in the intermediate-risk group and 25 cases in the high-risk group; 8 cases in the complex karyotype group, 14 cases in the 11q23 rearrangement group, and 29 cases in the other karyotype groups.By the end of the follow-up on November 30, 2024, 11 patients relapsed, 8 patients died, and 13 patients developed grades Ⅱ-Ⅳ acute graft-versus-host disease (GVHD).The 3-year overall survival (OS), relapse-free survival (RFS), and grades Ⅱ-Ⅳ acute GVHD-free and relapse-free survival (GRFS) were 84.0% (95% CI: 74.4%-94.8%), 74.5% (95% CI: 63.4%-87.5%), and 58.8% (95% CI: 46.7%-74.0%), respectively.The 3-year OS of the high-risk group was significantly lower than that of the intermediate-risk group (71.8% vs.96.2%, P=0.022), while differences in 3-year RFS and GRFS between the 2 groups were not statistically significant (68.0% vs.80.8%, P=0.400; 52.0% vs.65.4%, P=0.420).The 3-year OS, RFS and GRFS of the complex karyotype group were significantly lower than those of 11q23 rearrangement and other karyotype groups (50.0% vs.85.7%, 93.1%, P=0.009; 37.5% vs.85.7%, 79.3%, P=0.022; 25.0% vs.64.3%, 65.5%, P=0.049).Multivariate analysis showed that a complex karyotype was an independent prognostic factor affecting 3-year OS and GRFS [OS: HR=6.79 (95% CI: 1.13-43.80), P=0.044; GRFS: HR=3.72(95% CI: 1.13-12.20), P=0.030]. Conclusions:High-risk cytogenetic features are significant predictors of survival outcomes in pediatric AML patients undergoing PTCy-based allo-HSCT.

Aim To investigate the expression levels of cytoplasmic FMR1-interacting protein-1(CYFIP1)in colorectal cancer and assess the impact of CYFIP1 interaction on the proliferation and apoptosis of colorec-tal cancer cell HT29,along with its potential mecha-nisms.Methods Immunohistochemistry was em-ployed to assess CYFIP1 expression in 32 colorectal cancer tissues and adjacent tissues.Coexpressed genes were identified using the GEPIA2 website to predict potential correlations and binding sites.Following the construction of a siRNA-CYFIP1,alterations in cell proliferation,apoptosis,and levels of apoptosis-related proteins were evaluated through CCK-8 assay,Hoechst 33342/PI double staining assay,and Western blot a-nalysis,respectively.Results The immunohisto-chemical findings revealed a significantly elevated level of CYFIP1 expression in colorectal cancer tissues com-pared to paracancer tissues(P<0.05).The expres-sion of CYFIP1 did not show any correlation with age and gender,but exhibited associations with TNM stage and lymph node metastasis(P<0.05).A conserved TP53 binding site was predicted in the 3kbps DNA re-gion upstream of the CYFIP1 gene using GEPIA2,JASPAR databases,and rVista 2.0 promoter prediction software.Following transfection of HT29 cells with siRNA-CYFIP1,the clonogenesis and proliferation of cells significantly decreased(P<0.05).Additional-ly,the levels of cleaved caspase-3 were elevated,while the expression levels of caspase-3 and Bcl-2 were reduced after transfection with siRNA-CYFIP1(P<0.05),which might be related to the interaction be-tween CYFIP1 and TP53.Conclusions The upregu-lation of CYFIP1 in colorectal cancer is associated with TNM stage and lymph node metastasis.Upon silen-cing,CYFIP1 demonstrates the ability to suppress pro-liferation in HT29 cells and modulate the expression of apoptotic proteins.
