Diabetic kidney disease (DKD) is one of the major complications diabetes, and its pathological progression closely associated with lipid metabolic reprogramming. Under diabetic conditions, renal cells undergo significant abnormalities, including increased uptake, impaired fatty acid oxidation, disrupted cholesterol efflux, enhanced catabolism, as adaptive responses to stress. These changes result in accumulation lipids such free acids, diacylglycerol, ceramides, leading lipotoxicity that triggers inflammation fibrosis. Hypoxia DKD microenvironment suppresses oxidation promotes synthesis through HIF-1α pathway, while chronic exacerbates disturbances via inflammatory cytokines, inflammasomes, macrophage polarization. Targeting metabolism represents a promising therapeutic strategy for alleviating DKD; however, further clinical translational studies are warranted validate efficacy safety these approaches.

Extrapulmonary manifestations of COVID-19 have gained attention due to their links clinical outcomes and potential long-term sequelae1. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) displays tropism towards several organs, including the heart kidney. Whether it also directly affects liver has been debated2,3. Here we provide clinical, histopathological, molecular bioinformatic evidence for hepatic SARS-CoV-2. We find that injury, indicated by a high frequency abnormal function tests, is common feature in two independent cohorts patients with requiring hospitalization. Using autopsy samples obtained from third patient cohort, multiple levels SARS-CoV-2 tropism, viral RNA detection 69% specimens, successful isolation infectious tissue postmortem. Furthermore, identify transcription-, proteomic- transcription factor-based activity profiles samples, revealing similarities signatures associated other infections human liver. Together, comprehensive multimodal analysis which increases our understanding consequences severe could be useful identification organ-specific pharmacological targets.

Diabetic kidney disease (DKD) is a long-term and serious complication of diabetes that affects millions people worldwide. It characterized by proteinuria, glomerular damage, renal fibrosis, leading to end-stage disease, the pathogenesis complex involves multiple cellular molecular mechanisms. Among three kinds intraglomerular cells including podocytes, endothelial (GECs) mesangial (MCs), alterations in one cell type can produce changes others. The cell-to-cell crosstalk plays crucial role maintaining filtration barrier (GFB) homeostasis. In this review, we summarized recent advances understanding pathological interactions these types DKD then focused on signaling pathways factors mediate crosstalk, such as angiopoietins, vascular growth factors, transforming factor-β, Krüppel-like retinoic acid receptor response protein 1 exosomes, etc. Furthermore, also simply introduce application latest technologies studying within new promising mediators for DKD. conclusion, review provides comprehensive updated overview highlights its importance development novel intervention approaches.

Current therapies for Fabry disease are based on reversing intracellular accumulation of globotriaosylceramide (Gb3) by enzyme replacement therapy (ERT) or chaperone-mediated stabilization the defective enzyme, thereby alleviating lysosomal dysfunction. However, their effect in reversal end-organ damage, like kidney injury and chronic disease, remains unclear. In this study, ultrastructural analysis serial human biopsies showed that long-term use ERT reduced Gb3 podocytes but did not reverse podocyte injury. Then, a CRISPR/Cas9-mediated α-galactosidase knockout cell line confirmed ERT-mediated without resolution Transcriptome-based connectivity mapping SILAC-based quantitative proteomics identified α-synuclein (SNCA) as key event mediating Genetic pharmacological inhibition SNCA improved structure function podocytes, exceeding benefits ERT. Together, work reconceptualizes Fabry-associated beyond accumulation, introduces modulation potential intervention, especially patients with nephropathy.

Diabetic kidney disease (DKD) is the leading cause of end-stage renal and number patients affected increasing worldwide. Thus, there a need to establish new treatment for DKD improve prognosis diabetic patients. Recently, it has shown that intracellular metabolic abnormalities are involved in pathogenesis DKD. In particular, activity mechanistic target rapamycin complex 1 (mTORC1), nutrient-sensing signaling molecule, hyperactivated various organs patients, which suggests involvement excessive mTORC1 activation diabetes. DKD, may be podocyte damage, causes proteinuria, tubular cell injury decreases function. Therefore, elucidating role developing therapeutic agents suppress hyperactivity shed light on treatments future.

The effects of healthy aging on the kidney, and how these intersect with superimposed diseases, are highly relevant in context population's increasing longevity. Age-associated changes to podocytes, which terminally differentiated glomerular epithelial cells, adversely affect kidney health. This review discusses molecular cellular mechanisms underlying podocyte aging, might be augmented by disease aged approaches mitigate progressive damage podocytes. Furthermore, we address biologic pathways such as those associated growth confound humans rodents.

Renal podocyte injury, apoptosis and autophagy are involved in the occurrence development of diabetic nephropathy (DN). Kaempferol (KPF) has promotion inhibition properties miscellaneous diseases, but these functions DN have not yet been elucidated.We used db/db mice to evaluate protective role KPF on DN. The anti-DN effect was evaluated by urine albumin-to-creatinine ratio pathological changes kidney tissue. Injury podocytes observed through Transmission electron microscopy. Immunofluorescence, Western blot, Immunohistochemistry were detect protein expression podocyte-associated molecules, autophagy, AMPK/mTOR pathway.We demonstrated that treatment significantly attenuated diabetes-induced albuminuria glycolipid metabolism dysfunction. In addition, alleviated mesangial matrix expansion, glomerular basement membrane thickening loss or fusion podocytes. Mechanistically, regulated autophagic proteins (upregulated LC3II, Beclin-1, Atg7 Atg 5, downregulated p62/SQSTM1), accompanied inhibited renal (downregulated Caspase 3 Bax, upregulated Bcl-2). could regulate signaling pathways increasing p-AMPK decreasing p-mTOR expressions.In conclusion, might a reduced enhanced which correlated with regulating pathways.
