Abstract
Diabetic kidney disease (DKD) is a prevalent complication of diabetes, often leading to end-stage renal disease. Animal models have been widely used to study the pathogenesis of DKD and evaluate potential therapies. However, current animal models often fail to fully capture the pathological characteristics of renal injury observed in clinical patients with DKD. Additionally, modeling DKD is often a time-consuming, costly, and labor-intensive process. The current review aims to summarize modeling strategies in the establishment of DKD animal models by utilizing meta-analysis related methods and to aid in the optimization of these models for future research. A total of 1215 articles were retrieved with the keywords of "diabetic kidney disease" and "animal experiment" in the past 10 years. Following screening, 84 articles were selected for inclusion in the meta-analysis. Review manager 5.4.1 was employed to analyze the changes in blood glucose, glycosylated hemoglobin, total cholesterol, triglyceride, serum creatinine, blood urea nitrogen, and urinary albumin excretion rate in each model. Renal lesions shown in different models that were not suitable to be included in the meta-analysis were also extensively discussed. The above analysis suggested that combining various stimuli or introducing additional renal injuries to current models would be a promising avenue to overcome existing challenges and limitations. In conclusion, our review article provides an in-depth analysis of the limitations in current DKD animal models and proposes strategies for improving the accuracy and reliability of these models that will inspire future research efforts in the DKD research field.

Admixture Mapping of Sepsis in European Individuals With African Ancestries. Front Med (Lausanne) 2022; 9:754440. [PMID: 35345767 PMCID: PMC8957104 DOI: 10.3389/fmed.2022.754440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Accepted: 01/24/2022] [Indexed: 11/30/2022] Open
Abstract
Sepsis is a severe systemic inflammatory response to infections that is accompanied by organ dysfunction. Although the ancestral genetic background is a relevant factor for sepsis susceptibility, there is a lack of studies using the genetic singularities of a recently admixed population to identify loci involved in sepsis susceptibility. Here we aimed to discover new sepsis loci by completing the first admixture mapping study of sepsis in Canary Islanders, leveraging their distinctive genetic makeup as a mixture of Europeans and African ancestries. We used a case-control approach and inferred local ancestry blocks from genome-wide data from 113,414 polymorphisms genotyped in 343 patients with sepsis and 410 unrelated controls, all ascertained for grandparental origin in the Canary Islands (Spain). Deviations in local ancestries between cases and controls were tested using logistic regressions, followed by fine-mapping analyses based on imputed genotypes, in silico functional assessments, and gene expression analysis centered on the region of interest. The admixture mapping analysis detected that local European ancestry in a locus spanning 1.2 megabases of chromosome 8p23.1 was associated with sepsis (lowest p = 1.37 × 10−4; Odds Ratio [OR] = 0.51; 95%CI = 0.40–0.66). Fine-mapping studies prioritized the variant rs13249564 within intron 1 of MFHAS1 gene associated with sepsis (p = 9.94 × 10−4; OR = 0.65; 95%CI = 0.50–0.84). Functional and gene expression analyses focused on 8p23.1 allowed us to identify alternative genes with possible biological plausibility such as defensins, which are well-known effector molecules of innate immunity. By completing the first admixture mapping study of sepsis, our results revealed a new genetic locus (8p23.1) harboring a number of genes with plausible implications in sepsis susceptibility.

J Cell Physiol 2020; 236:3044-3058. [PMID: 33090488 DOI: 10.1002/jcp.30083] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2020] [Revised: 09/07/2020] [Accepted: 09/09/2020] [Indexed: 01/15/2023]
Abstract
The aim of this study was to investigate the role of scoparone (SCO) in hepatic fibrosis. For this, we conducted in vivo and in vitro experiments. In vivo rats that were divided into six groups, control, carbon tetrachloride, and colchicine, as well as SCO groups, SCO50, SCO100, and SCO200 treated with 50, 100, and 200 mg/kg SCO doses, respectively. Furthermore, SCO was shown to inhibit Toll-like receptor-4 (TLR-4)/nuclear factor kappa-B (NF-κB; TLR-4/NF-κB) signals by inhibiting TLR-4, which in turn downregulates the expression of MyD88, promotes NF-κB inhibitor-α, NF-κB inhibitor-β, and NF-κB inhibitor-ε activation, while inhibiting NF-κB inhibitor-ζ. Subsequently, the decrease of phosphorylation of nuclear factor-κB levels leads to the downregulation of the downstream inflammatory factors' tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1 beta, thus weakening hepatic fibrosis. Notably, the SCO200 treated group presented the most significant improvement. Hence, we conclude that SCO alleviates hepatic fibrosis by inhibiting TLR-4/NF-κB signals.
