Project description:Background: Recent single-cell RNA sequencing (scRNA-seq) analyses have offered much insight into cell-specific gene expression profiles in normal kidneys. However, in diseased kidneys, understanding of changes in specific cells, particularly glomerular cells, remains limited. Methods: To elucidate the glomerular cell–specific gene expression changes in diabetic kidney disease, we performed scRNA-seq analysis of isolated glomerular cells from streptozotocin-induced diabetic endothelial nitric oxide synthase (eNOS)–deficient (eNOS-/-) mice and control eNOS-/- mice. Results: We identified five distinct cell populations, including glomerular endothelial cells, mesangial cells, podocytes, immune cells, and tubular cells. Using scRNA-seq analysis, we confirmed the expression of glomerular cell–specific markers and also identified several new potential markers of glomerular cells. The number of immune cells was significantly higher in diabetic glomeruli compared with control glomeruli, and further cluster analysis showed that these immune cells were predominantly macrophages. Analysis of differential gene expression in endothelial and mesangial cells of diabetic and control mice showed dynamic changes in the pattern of expressed genes, many of which are known to be involved in diabetic kidney disease. Moreover, gene expression analysis showed variable responses of individual cells to diabetic injury. Conclusion: Our findings demonstrate the ability of scRNA-seq analysis in isolated glomerular cells from diabetic and control mice to reveal dynamic changes in gene expression in diabetic kidneys, with variable responses of individual cells. Such changes, which might not be apparent in bulk transcriptomic analysis of glomerular cells, may help identify important pathophysiologic factors contributing to the progression of diabetic kidney disease.

Project description:Activation of A Disintegrin and A Metalloprotease Domain17 (ADAM17) is involved in nephropathy, but the role of this metalloprotease and its inhibitor TIMP3 in diabetic kidney disease is unclear. We used microarray profiling to find genes differentially expressed in the 2 genotypes which could explain the more severe diabetic kidney disease features observed in T3-/- mice compared to the WT littermates. Total RNA was extracted from 3 WT and 3 Timp3-/- diabetic kidneys

Project description:The pathogenesis of diabetic kidney disease (DKD) involves multifactorial processes that converge to initiate and advance the disease. Although DKD is not typically classified an inflammatory glomerular disease, mounting evidence supports the involvement of renal inflammation as a key contributor in DKD pathogenesis. However, detailed characteristics of specific immune cell types in the context of diabetic kidneys remain poorly understood. To capture the gene expression changes in specific immune cell subsets in early DKD, we performed a single-cell transcriptomic analysis of CD45-enriched kidney immune cells from control and diabetic OVE26 mice. Unsupervised clustering identified 11 distinct cell types that represented the major immune cells and an unidentified cell type. Further analysis of mononuclear phagocytes showed increased macrophage subsets in the diabetic kidneys and that pro-inflammatory and anti-inflammatory macrophages were concomitantly increased. Moreover, rather than in discrete M1 or M2 states, many macrophage subsets expressed genes consistent with the continuum of activation and differentiation states, and that their gene expression shifted toward increased inflammatory and differentiated status in the diabetic kidneys. Our study provides a comprehensive analysis of immune cell transcriptomic profiles in mouse DKD and underscores the dynamic macrophage activation in promoting DKD.

Project description:Diabetic nephropathy is a chronic complication of diabetes, presenting albuminuria at an early stage and leading to renal failure. Kidney is a complicated organ, which is responsible for body fluids control, acid-base balance, and removal of toxins. To better understand the progress of diabetic nephropathy, mice renal cortex of control mice, six-week db-/- (increased serum glucose without pathological changes in kidneys), and ten-week db-/- (with pathological changes in kidneys) were collected for single-cell sequencing analyses. A subgroup of glomerular endothelial cells with pro-angiogenetic features was identified in diabetic kidneys.

Project description:There is a temporal window from the time diabetes is diagnosed to the appearance of overt kidney disease during which time the disease progresses quietly without detection. Currently, there is no way to detect early diabetic nephropathy (EDN). Here we performed an unbiased assessment of gene-expression analysis of postmortem human kidneys using microarrays to identify candidate genes that may contribute to EDN.

Project description:The most relevant pomegranate phenolics (ellagitannins and ellagic acid) are extensively metabolized by the human gut microbiota to yield a number of metabolites called urolithins (mainly Uro-A). Urolithins have been reported to regulate in vivo the expression of genes involved in inflammation and cancer. Our hypothesis is that urolithins can be detected in the human colon mucosa where these metabolites can exert anti-inflammatory and anti-cancer activities. After colonoscopy and diagnosis, colorectal cancer patients will consume capsules containing three different pomegranate extract formulations until surgery. The aims of this trial are:
* To evaluate the disposition of pomegranate phenolics and urolithins in tumoral and normal colon tissues.
* To evaluate gene expression profiling and protein markers in tumoral and normal colon tissues from these patients.
* To compare different pomegranate extract formulations on the above.

Project description:The transcription factor c-Maf has been widely studied and has been reported to play a critical role in embryonic kidney development; however, the postnatal functions of c-Maf in adult kidneys remain unknown as c-Maf null C57BL/6J mice exhibit embryonic lethality. In this study, we investigated the role of c-Maf in adult mouse kidneys by comparing the phenotypes of tamoxifen (TAM)-inducible c-Maf knockout mice (c-Maf flox/flox; CAG-Cre-ERTM mice named “c-Maf ΔTAM”) with that of c-Maf flox/flox control mice, 10 days after TAM injection (TAM(10d)). In addition, we examined the effects of c-Maf deletion on diabetic conditions by injecting the mice with streptozotocin (STZ), 4 weeks before TAM injection. c-Maf ΔTAM mice displayed primary glycosuria caused by Sglt2 and Glut2 downregulation in the kidneys without diabetes, as well as morphological changes and life-threatening injuries in the kidneys on TAM(10d). Under diabetic conditions, c-Maf deletion promoted recovery from hyperglycemia and suppressed albuminuria and diabetic nephropathy by causing similar effects as did Sglt2 knockout and SGLT2 inhibitors. In addition to demonstrating the unique gene regulation of c-Maf, these findings highlight the renoprotective effects of c-Maf deficiency under diabetic conditions and suggest that c-Maf could be a novel therapeutic target gene for treating diabetic nephropathy.
