D-Serine activates glycolysis via mTOR pathway in kidney remodeling and suppresses onset of diabetes

ABSTRACT: D-Serine, a long-term undetected enantiomer of serine1,2, is a novel biomarker that reflects kidney function and disease activity3-5 and has unclear physiological functions. Here we show that D-serine is a physiological molecule that promotes tissue remodeling and suppresses the onset of diabetes. D-serine is quickly and dominantly distributed to the kidney upon injection in mice, suggesting that the kidney is a key target organ. Unilateral nephrectomy in human living kidney donors decreases urinary excretion and thus increases the blood level of D-serine, which in turn promotes the compensatory enlargement of the remnant kidney in mouse model. D-Serine activates cell cycle for tissue remodeling through an mTOR-related pathway, which promotes metabolic reprograming to glycolytic activation. In rodent diabetic model, D-serine promotes glycolysis in the kidney and suppresses the surge of blood glucose levels. D-Serine has physiological activity that influences kidney function and maintains metabolic homeostasis to reduce diabetic propensity.

Comparison of transcriptome landscape between adenine-induced and nephrectomy-induced uremic cardiomyopathy

Project description:Adenine and nephrectomy can be used to establish models of uremic cardiomyopathy in rodents. Although these two approaches cause similar phenotypes of heart, adenine may directly act on cardiomyocytes and lead to different molecular changes from nephrectomy-induced uremic cardiomyopathy. Transcriptome analysis on left ventricles showed 789 upregulated and 345 downregulated genes in mice with nephrectomy-induced uremic cardiomyopathy compared to control mice, while 432 upregulated and 155 downregulated genes in mice with adenine diet-induced uremic cardiomyopathy compared to control mice. Functional analysis revealed that these DEGs were involved in pathways related to immune inflammation, metabolic responses, and synaptic transmission. Further analysis demonstrated that nephrectomy-induced uremic cardiomyopathy has enhanced cell cycle process/extracellular matrix remodeling and suppressed fatty acid metabolism, whereas adenine diet-induced uremic cardiomyopathy only exhibits increased inflammatory response/extracellular matrix remodeling. Compared with nephrectomy-induced uremic cardiomyopathy, adenine diet-induced uremic cardiomyopathy showed improved oxidative phosphorylation, aerobic electron transport chain, and tricarboxylic acid cycle, and suppressed cell cycle-related process, indicating that adenine and its derivates may affect the process of chronic kidney induced cardiac changes.

Project description:From the past reports, we hypothesized that spleen is an ideal site for inducing regeneration of transplanted islets, and leading to reduce the required number of islets for ameliorating the hyperglycemia of diabetic recipients in mice. In order to confirm this hypothesis, we performed 25 islets transplantation into spleen (SP25); it was not enough number to ameliorate the hyperglycemia of recipient mice, with 100 islets transplantation into beneath the kidney capsule (KC100) to maintain recipients' blood glucose normoglycemic temporary. All recipient mice (n=11) became normoglycemic after receiving SP25 with KC100. On 240 days after transplantation, we performed nephrectomy for removing islet grafts in the kidney. After nephrectomy, 8 of 11 mice remained normoglycemic, and 3 of 11 mice' non-fasting blood glucose levels were maintained around 300 mg/dL. On 290 days after transplantation (50 days after nephrectomy), all recipient mice received splenectomy to remove islet grafts in the spleen. All mice became hyperglycemic after splenectomy, indicating that intra-splenic islet grafts maintained the blood glucose levels of diabetic recipient mice. In order to investigate the gene expression associated with islets engraftment in the spleen, microarray studies were performed in comparison of the Tlx-1 (Hox11) related gene expression profiles of Sample 1, Sample 2 and Sample 3.

Dysfunction of the circadian clock in the renal tubule leads to enhanced renal gluconeogenesis and exacerbated hyperglycemia in diabetes

Project description:In diabetes, the kidney contributes to the development of diabetic hyperglycemia by increasing glucose reabsorption from the primary urine and by upregulating gluconeogenesis in the proximal tubule. However, these two processes are also controlled by the circadian clock, a mechanism that synchronizes a large number of specific renal functions with environmental daily cycles. Here, we investigated the (patho)physiological role of intrinsic renal tubule circadian clocks in the diabetic kidney. We demonstrate that diabetic mice devoid of the circadian transcriptional regulator BMAL1 in the renal tubule exhibit additional enhancement of renal gluconeogenesis, exacerbated hyperglycemia, increased glucosuria, polyuria and renal hypertrophy. Collectively, our results suggest that diabetic hyperglycemia can be worsened by dysfunction or misalignment of intrinsic renal circadian clocks.

Project description:In this study, we compared the transcriptomes of the kidney subjected to unilateral IRI with contralateral nephrectomy (IRI/CL-NX) and the normal healthy control kidney at the single cell level to identify major cell types in the kidney and the differential transcriptional response during kidney repair following IRI.

Urinary peptidomics in youths with and without type 1 diabetes

Project description:Although the early mechanisms responsible for diabetic kidney disease remain unclear, it is widely believed that chronic hyperglycemia disrupts the proteolytic milieu in the diabetic kidney and may contribute to early kidney injury. We thus performed mechanistic peptidomics in type 1 diabetes before the onset of microalbuminuria. In the discovery cohort of 30 participants, we identified 6550 peptides from 753 proteins. After removing false hits and potential contaminants, there were 6323 quantified peptides: 5708 peptides can be found in youths with type 1 diabetes, 5011 in healthy controls, and 4396 common to both groups. After applying a cut-off of 100%, there were 162 peptides found in each and every urine sample. From this subset, fifteen peptides were differentially excreted between youths with type 1 diabetes and their non-diabetic peers (P < 0.05, t-test); five remained significant after Benjamini-Hochberg adjustment (Q < 0.05). Excretion rates of six peptides were validated in a second cohort of thirty participants using parallel reaction monitoring (separate PRIDE file). Interestingly, these peptides originated from a small region near the C-terminus of uromodulin, a kidney-specific protein. In silico analyses of cleavage sites implicated several metallo and serine proteases involved in wound healing. Two of the uromodulin peptides activated NFκB in a TLR4-dependent manner in cultured kidney tubular cells and also promoted neutrophil migration in vitro. In summary, the differential excretion of uromodulin peptides may shed light onto early inflammatory processes in the diabetic kidney.

A KLF2-BMPER-Smad1/5 checkpoint regulates high fluid shear stress-mediated artery remodeling

Project description:Vascular remodeling to match arterial diameter to tissue metabolic requirements commonly fails in ischemic disease. Endothelial cells (EC) sense fluid shear stress (FSS) from blood flow to maintain FSS within a narrow range in healthy vessels. Higher FSS induces vessel outward remodeling to return FSS to physiological levels, but mechanisms are poorly understood. We previously reported that Smad1/5 is maximally activated at physiological FSS and suppressed at higher flow. The Smad1/5 pathway opposes activation of Akt, suggesting that inhibiting Smad1/5 may be required for outward remodeling. Here, we report that suppression of Smad1/5 at high FSS is mediated by elevated KLF2, which induces the BMP pathway inhibitor BMPER, which suppresses Smad1/5 and de-inhibits Akt. In a mouse arteriovenous fistula (AVF) model, high FSS induces arterial outward remodeling coincident with elevated BMPER expression and Smad1/5 inactivation. Endothelial BMPER deletion impaired blood flow recovery and vascular remodeling in the AVF and a hindlimb ischemia (HLI) model, with the latter reversed by BMP9/10 blocking antibodies (bAbs). In both STZ-induced type 1 and HFD-induced type 2 diabetic mice that show poor recovery from HLI, BMP9/10 bAbs improved outcomes. Thus, suppression of Smad1/5 is required for high FSS-mediated outward remodeling and is a potential therapeutic approach for ischemic disease.
