Project description:Diabetic kidney disease (DKD) is a significant clinical challenge, with an increasing prevalence. Our research identified that fibroblast growth factor 4 (FGF4) secreted by podocytes is a key factor in a mouse model of DKD. Given the importance of FGF4 in DKD-induced kidney injury, we performed gene expression analysis on kidney tissues. This analysis compared db/db model mice with those treated with recombinant FGF4 (rFGF4). The results showed that, compared to the db/db model group, db/db mice treated with long-term rFGF4 demonstrated significant improvements in renal function markers, such as serum urea nitrogen and urinary protein levels.Overall, our findings indicate that FGF4 is a critical regulatory factor in DKD-induced renal injury, providing evidence that it alleviates glomerular damage by inhibiting oxidative stress and apoptosis.

Project description:We identified 1,700 differentially expressed probesets in DKD glomeruli and 1,831 in diabetic tubuli; 330 probesets were commonly differentially expressed in both compartments. The canonical complement signaling pathway was determined to be statistically differentially regulated in both DKD glomeruli and tubuli and was associated with increased glomerulosclerosis even in an additional set of DKD samples. Affymetrix expression arrays were used to identify differentially regulated transcripts in 44 microdissected human kidney samples. Stringent statistical analysis using the Benjamini_Hochberg corrected 2-tailed t-test was used to identify differentially expressed transcripts in control and diseased glomeruli and tubuli. This Series includes DKD and control glomeruli samples.

Project description:Analysis of gene expression changes in differentiated human podocytes treated with the serum from patients with (DKD+) or without (DKD-) diabetic kidney disease when compared to normal subjects (C). The hypothesis is that the three groups can be distinghed by their differential gene expression pattern. The results obtained revealed important information regarding differences in gene expression in human podocytes treated with the serum from patients with (DKD+) or without (DKD-) diabetic kidney disease when compared to normal subjects (C). Human podocytes were contacted with the serum from patients with diabetes and kidney disease (DKD+) or without kidney disease (DKD-) and compared to normal human podocytes contacted with serum from patients without diabetes (C).

Project description:Peptidyl Arginine Deiminase 4 (PAD4) is an enzyme predominantly expressed in myeloid cells, and its role in diabetic kidney disease (DKD) remains unknown. We functionally characterized 48 PAD4 variants identified among 469,779 participants from UK Biobank and examined their associations with renal function. We found that 32 PAD4 variants causes loss of function, which was significantly associated with higher estimated glomerular filtration rate. We observed an enhanced PAD4 expression in renal tubulointerstitium among DKD patients and animal models of DKD. Both PAD4 deficiency in macrophages and PAD4 inhibitor GSK484 significantly alleviated renal tubulointerstitial injury by reducing macrophage infiltration in diabetic mice models. Mechanistically, PAD4 interacted with p65 to promote its binding to Cmklr1 promoter and induce the expression of Cmklr1, which led to an enhanced macrophage migration. These findings demonstrate the crucial role of PAD4-mediated macrophage migration in tubulointerstitial injury of DKD.
