Annexin A13 protects against acute kidney injury by inactivating TGF-β/Smad3 signaling

ABSTRACT: Acute kidney injury (AKI) is a common cause of chronic kidney disease, but the pathogenic mechanisms remain unclear and treatments remain limited. Here we report that Annexin A13 (ANXA13), the founder member of Annexins is renal protective in AKI. Clinically, ANXA13 was lost in the AKI kidney in both patients and ischemic-reperfusion injury (IRI)-induced mice. This was associated with declined serum levels of ANXA13 but elevated urinary ANXA13. To explore the functional role of ANXA13 in AKI, we kidney-specifically overexpressed ANXA13 and found that overexpressing ANXA13 protected against IRI-AKI by significantly inhibiting tubular necrosis and lowering serum creatinine. In contrast, kidney-specifically silencing ANXA13 largely promoted AKI. Mechanistically, renal ANXA13 was downregulated by TGF-β1 via Smad3 signaling as mice lacking Smad3 were protected from the loss of renal ANXA13 and the development of AKI. More importantly, we also uncovered that ANXA13 could directly bind TGF-β receptor type 1 and inhibit its phosphorylation, thereby inactivating Smad3 signaling and Smad3-mediated tubular cell death via the p21-dependent G1cell cycle arrest. In conclusion, ANXA13 is renal protective and may be a potential new biomarker and a novel therapeutic agent for AKI.

Tubular epithelial NF-κB activity regulates acute ischemic kideny injury [OTT-211009]

Project description:NF-κB is a key regulator of innate and adaptive immunity and is implicated in the pathogenesis of acute kidney injury (AKI). The cell type-specific functions of NF-κB in the kidney are unknown; however, the pathway serves distinct functions in immune and tissue-parenchymal cells. We analyzed tubular epithelial-specific NF-κB signaling in a mouse model of ischemia-reperfusion injury (IRI)-induced AKI. NF-κB reporter activity and nuclear localization of phosphorylated NF-κB subunit p65 analyses in mice revealed widespread NF-κB activation in renal tubular epithelia and in interstitial cells following IRI that peaked at 2-3 days after injury. To genetically antagonize tubular epithelial NF-κB activity, we generated mice expressing the human NF-κB super-repressor IκBα∆N in renal proximal, distal, and collecting duct epithelial cells. These mice were protected from IRI-induced AKI, as indicated by improved renal function, reduced tubular apoptosis, and attenuated neutrophil and macrophage infiltration. Tubular NF-κB-dependent gene expression profiles revealed temporally distinct functional gene clusters for apoptosis, chemotaxis, and morphogenesis. Primary proximal tubular cells isolated from IκBα∆N-expressing mice exposed to hypoxia-mimetic agent cobalt chloride were protected from apoptosis and expressed reduced levels of chemokines. Our results indicate that postischemic NF-κB activation in renal-tubular epithelia aggravates tubular injury and exacerbates a maladaptive inflammatory response.

Effects of GPX3-Specific Knockout in Renal Tubular Epithelial Cells on Kidney Gene Expression During the IRI-AKI Process

Project description:GPX3 is primarily synthesized and secreted by renal tubular epithelial cells and serves as the main source of GPX3 in plasma. A portion of GPX3 adheres to the renal basement membrane, suggesting that GPX3 may also regulate renal cell physiological functions. Our previous work has found that GPX3 expression is downregulated in the renal tubular epithelial cells of mice that have undergone ischemia-reperfusion-induced acute kidney injury, but the specific impact of this downregulation remains unclear. To address this, we constructed mice with specific deletion of GPX3 in renal tubular epithelial cells and subjected them to ischemia-reperfusion modeling. We reported the protective role of native GPX3 in the kidneys under IRI-AKI conditions in mitigating oxidative stress and mitochondrial damage in tubular epithelial cells. The deletion of GPX3 in tubular epithelial cells exacerbated oxidative stress, apoptosis, and mitochondrial dysfunction in IRI-AKI. Renal cortex tissue from control and IRI-modeled mice was used for RNA sequencing. Overall, our data provide an overview of the genetic changes in the kidneys of mice with GPX3 knockout in both non-modeled and IRI-AKI-modeled conditions, laying the groundwork for studying the specific mechanisms by which GPX3 regulates renal function.

Inhibition of prolyl hydroxylase promotes the reprogramming of Sox9+ renal progenitor cells and renal regeneration

Project description:Mammalian kidney has very limited ability to repair or regenerate after acute kidney injury (AKI). The maladaptive repair of AKI promotes the progression to chronic kidney disease (CKD). Therefore, it is extremely urgent to explore new strategies to promote the repair/regeneration of injured renal tubules after AKI. It has been shown that hypoxia induces heart regeneration in adult mice. However, it is unknown whether hypoxia can induce kidney regeneration after AKI. In this study, we used a prolyl hydroxylase domain inhibitor (PHDI), MK-8617, to mimic hypoxia condition and found that MK-8617 significantly ameliorates ischemia reperfusion injury (IRI) induced acute kidney injury. We then showed that MK-8617 dramatically facilitates renal regeneration via promoting the proliferation of injured renal proximal tubular cells (RPTCs) after IRI-induced AKI. We then performed bulk mRNA sequencing and discovered that multiple nephrogenesis- related genes were significantly upregulated with MK-8617 pretreatment. Furthermore, we showed that MK-8617 may alleviate proximal tubule injury via stabilizing HIF-1α protein specifically in renal proximal tubular cells. We also demonstrated that MK-8617 promotes the reprogramming of renal proximal tubular cells to Sox9+ renal progenitor cells, and the regeneration of renal proximal tubules. In summary, we discovered that inhibition of prolyl hydroxylase improves renal proximal tubule regeneration after IRI-induced AKI via promoting the reprogramming of renal proximal tubular cells to Sox9+ renal progenitor cells.

Evaluation of renal mononuclears cells in acute kidney injury after inhibiting retinoic acid signaling in proximal tubular epithelial cells

Project description:Retinoic acid (RA) signaling is activted in proximal tubular epithelial cells (PTECs) after acute kidney injury (AKI). In these studies we evaluated the functional role of this by inducing ischemia reperfusion-induced AKI (IRI-AKI) in mice after inhibiting RA signaling in PTECs genetically. Here we evaluated the effects of this on the activation of renal mononuclear cells (MNCs) by evaluating RNA expression in CD11B+ cells isolated from kidneys after IRI-AKI. Compared with control mice, there was a reducion in expression of inflammatory marker gene expression 3 days after IRI-AKI in mice with inhibition of RAR signaling in PTECs. These findings suggest a mechanism by which inhibition of RAR signaling in PTECs is protective against AKI.

NLRC5 deficiency protects against acute kidney injury in mice by mediating CEACAM1 signaling

Project description:Although there is significant progress in understanding the structure and function of NLRC5, a member of the NOD like receptor (NLR) family, in the context of MHC class I gene expression, the functions of NLRC5 in innate and adaptive immune responses beyond the regulation of MHC class I genes remain controversial and unresolved. In particular, the role of NLRC5 in the kidney keeps unknown. In this study, we found that NLRC5 was significantly upregulated in the kidney from mice with renal ischemia/reperfusion injury (IRI). NLRC5 deficient (NLRC5-/-) mice significantly ameliorated renal injury as evidenced by decreased serum creatinine levels, improved morphological injuries, and reduced inflammatory responses versus wild type mice. Similar protective effects were also observed in cisplatin-induced acute kidney injury (AKI). Mechanistically, NLRC5 contributed to renal injury by promoting tubular epithelial cell apoptosis and reducing inflammatory responses which is associated with, at least in part, the negative regulation of carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1). To determine the relative contribution of NLRC5 expression by parenchymal cells or leukocytes to renal damage during IRI, we generated bone marrow (BM) chimeric mice. NLRC5-/- mice engrafted with WT hematopoietic cells had significantly lower serum creatinine and less tubular damage than WT mice reconstituted with NLRC5-/- BM, suggesting that NLRC5 signaling in renal parenchymal cells plays the dominant role in mediating renal damage. Collectively, modulation of NLRC5-mediated pathway may have important therapeutic implications for patients with AKI.

Proteomic experiment of lysine crotonylation modification to analysis of the role of knocking down NRP1 after IR in kidney

Project description:Neuropilin-1 (NRP1), a co-receptor for various cytokines, including TGF-β, has been identified as a potential therapeutic target for fibrosis. However, its role and mechanism in renal fibrosis remains elusive. Here, we show that NRP1 is upregulated in distal tubular (DT) cells of patients with transplant renal insufficiency and mice with renal ischemia-reperfusion (I-R) injury. Knockout of Nrp1 reduced multiple endpoints of renal injury and fibrosis. We found that Nrp1 facilitates the binding of TNF-α to its receptor in DT cells after renal injury. This signaling results in a downregulation of lysine crotonylation of the metabolic enzyme Cox4i1, decreased cellular energetics and exacerbation of renal injury. Furthermore, by single-cell RNA-sequencing we found that Nrp1-positive DT cells secrete collagen and communicate with myofibroblasts, exacerbating acute kidney injury (AKI)-induced renal fibrosis by activating Smad3. Dual genetic deletion of Nrp1 and Tgfbr1 in DT cells better improves renal injury and fibrosis than either single knockout. Together, these results reveal that targeting of NRP1 represents a promising strategy for the treatment of AKI and subsequent chronic kidney disease.

HNF3α targets Nckap1l and promotes renal fibrosis following ischemia-reperfusion injury

Project description:Ischemia-reperfusion injury-induced acute kidney injury is a major cause of chronic kidney disease, lacking effective interventions. We found elevated HNF3α expression in CKD patients, which correlated with collagen deposition, serum creatinine, and urea levels. Conditional knockout of HNF3α in renal tubular epithelial cells protected against IRI-induced renal fibrosis in vivo. To explore the mechanisms by which HNF3α promotes renal fibrosis, we transfected TKPTS cells with Hnf3a overexpression plasmids or control plasmids, and then performed transcriptome sequencing.
