Abstract
Background The interplay between gut microbiota and metabolites in the early stages of sepsis-induced acute kidney injury (SA-AKI) is not yet clearly understood. This study explores the characteristics and interactions of gut microbiota, and blood and urinary metabolites in patients with SA-AKI. Methods Utilizing a prospective observational approach, we conducted comparative analyses of gut microbiota and metabolites via metabolomics and metagenomics in individuals diagnosed with SA-AKI compared to those without AKI (NCT06197828). Pearson correlations were used to identify associations between microbiota, metabolites, and clinical indicators. The Comprehensive Antibiotic Resistance Database was employed to detect antibiotic resistance genes (ARGs), while Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways informed on metabolic processes and microbial resistance patterns. Results Our study included analysis of four patients with SA-AKI and five without AKI. Significant disparities in bacterial composition were observed, illustrated by diversity indices (Shannon index: 2.0 ± 0.4 vs. 1.4 ± 0.6, P = 0.230; Simpson index: 0.8 ± 0.1 vs. 0.6 ± 0.2, P = 0.494) between the SA-AKI group and the non-AKI group. N6, N6, N6-Trimethyl-L-lysine was detected in both blood and urine metabolites, and also showed significant correlations with specific gut microbiota (Campylobacter hominis and Bacteroides caccae, R > 0, P < 0.05). Both blood and urine metabolites were enriched in the lysine degradation pathway. We also identified the citrate cycle (TCA cycle) as a KEGG pathway enriched in sets of differentially expressed ARGs in the gut microbiota, which exhibits an association with lysine degradation. Conclusions Significant differences in gut microbiota and metabolites were observed between the SA-AKI and non-AKI groups, uncovering potential biomarkers and metabolic changes linked to SA-AKI. The lysine degradation pathway may serve as a crucial link connecting gut microbiota and metabolites.

Downregulation of IL-1β/p38 mitogen activated protein kinase pathway by diacerein protects against kidney ischemia/reperfusion injury in rats. Cytokine 2024; 176:156511. [PMID: 38290257 DOI: 10.1016/j.cyto.2024.156511] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 12/08/2023] [Accepted: 01/16/2024] [Indexed: 02/01/2024]
Abstract
Renal ischemia-reperfusion (I/R) can be precipitated by multiple clinical situations that lead to impaired renal function and associated mortality. The resulting tubular cell damage is the outcome of complex disorders including, an inflammatory process with an overproduction of cytokines. Here, diacerein (DIA), an inhibitor of proinflammatory cytokine interleukin-1 beta (IL-1β), was investigated against renal I/R in rats. DIA was orally administrated (50 mg/kg/day) for ten days before bilateral ischemia for 45 min with subsequent 2 hr. reperfusion. Interestingly, DIA alleviated the renal dysfunction and histopathological damage in the renal tissues. Pretreatment with DIA corrected the oxidative imbalance by prevented reduction in antioxidant levels of GSH and SOD, while it decreased the elevation of the oxidative marker, MDA. In addition, DIA downregulated IL-1β and TNF-α expression in the renal tissues. Consequent to inhibition of the oxidative stress and inflammatory cascades, DIA inhibited the phosphorylation of p38 mitogen-activated protein kinase (p38 MAPK). Therefore, downstream targets for p38 MAPK were also inhibited via DIA which prevented further increases of inflammatory cytokines and the apoptotic marker, caspase-3. Collectively, this study revealed the renoprotective role of DIA for renal I/R and highlighted the role of p38 MAPK encountered in its therapeutic application in renal disease.

Abstract
Sepsis involves an immunological systemic response to a microbial pathogenic insult, leading to a cascade of interconnected biochemical, cellular, and organ-organ interaction networks. Potential drug targets can depict aquaporins, as they are involved in immunological processes. In immune cells, AQP3 and AQP9 are of special interest. In this study, we tested the hypothesis that these aquaporins are expressed in the blood cells of septic patients and impact sepsis survival. Clinical data, routine laboratory parameters, and blood samples from septic patients were analyzed on day 1 and day 8 after sepsis diagnosis. AQP expression and cytokine serum concentrations were measured. AQP3 mRNA expression increased over the duration of sepsis and was correlated with lymphocyte count. High AQP3 expression was associated with increased survival. In contrast, AQP9 expression was not altered during sepsis and was correlated with neutrophil count, and low levels of AQP9 were associated with increased survival. Furthermore, AQP9 expression was an independent risk factor for sepsis lethality. In conclusion, AQP3 and AQP9 may play contrary roles in the pathophysiology of sepsis, and these results suggest that AQP9 may be a novel drug target in sepsis and, concurrently, a valuable biomarker of the disease.

Abstract
Chronic kidney disease (CKD) is a serious problem which negatively affects human health. AIMS The purpose of this investigation was to explore the possible beneficial impacts of diacerein on adenine-induced CKD in rats. MAIN METHODS 32 male Sprague Dawley rats were allocated into 4 groups; normal, diseased (200 mg/kg adenine, orally) and diacerein (25 and 50 mg/kg, orally). KEY FINDINGS Adenine produced marked reduction in rats' body weights and a substantial increase in kidney/body weight index. Additionally, adenine significantly increased serum creatinine and BUN levels besides proteinuria levels, and also reduced creatinine clearance. Adenine induced oxidative stress as evidenced by increased MDA content and diminished GSH concentration in renal tissues. These biochemical measurements were confirmed by the morphological and histopathological results. Moreover, adenine revealed substantial elevation in renal level and expression of MYD88, TRAF6 and TNF-α, and renal level of IL-1β in addition to increased expression of TLR4, NF-κB p65 and p-NF-κB p65 while reduced the expression of IκB-α. Diacerein in a dose-dependent manner effectively ameliorated adenine-induced alterations. SIGNIFICANCE Diacerein could be used as a therapeutic agent to attenuate CKD after further clinical studies.

AQP3-mediated activation of the AMPK/SIRT1 signaling pathway curtails gallstone formation in mice by inhibiting inflammatory injury of gallbladder mucosal epithelial cells. Mol Med 2023; 29:116.

Abstract
BACKGROUND Inflammatory injury of gallbladder mucosal epithelial cells affects the development of cholelithiasis, and aquaporin 3 (AQP3) is an important regulator of inflammatory response. This study reports a mechanistic insight into AQP3 regulating gallstone formation in cholelithiasis based on high-throughput sequencing. METHODS A mouse model of cholelithiasis was induced using a high-fat diet, and the gallbladder tissues were harvested for high-throughput sequencing to obtain differentially expressed genes. Primary mouse gallbladder mucosal epithelial cells were isolated and induced with Lipopolysaccharides (LPS) to mimic an in vitro inflammatory injury environment. Cell biological phenotypes were detected by TdT-mediated dUTP Nick-End Labeling (TUNEL) assay, flow cytometry, Cell Counting Kit-8 (CCK-8) assay, and Trypan blue staining. In addition, enzyme linked immunosorbent assay (ELISA) determined the production of inflammatory factors in mouse gallbladder mucosa. RESULTS Whole-transcriptome sequencing data analysis identified 489 up-regulated and 1007 down-regulated mRNAs. Bioinformatics analysis revealed that AQP3 was significantly down-regulated in mice with cholelithiasis. AQP3 might also confer an important role in LPS-induced gallbladder mucosal injury. Overexpression of AQP3 activated the AMPK (adenosine monophosphate-activated protein kinase) / SIRT1 (sirtuin-1) signaling pathway to reduce LPS-induced inflammatory injury of the gallbladder mucosa epithelium, thereby ameliorating gallbladder damage and repressing gallstone formation in mice. CONCLUSION Data from our study highlight the inhibitory role of AQP3 in gallbladder damage and gallstone formation in mice by reducing inflammatory injury of gallbladder mucosal epithelial cells, which is achieved through activation of the AMPK/SIRT1 signaling pathway.

Abstract
Sepsis most often involves the kidney and is one of the most common causes of acute kidney injury. The prevalence of septic acute kidney injury has increased significantly in recent years. The gut microbiota plays an important role in sepsis. It interacts with the kidney in a complex and multifactorial process, which is not fully understood. Sepsis may lead to gut microbiota alteration, orchestrate gut mucosal injury, and cause gut barrier failure, which further alters the host immunological and metabolic homeostasis. The pattern of gut microbiota alteration also varies with sepsis progression. Changes in intestinal microecology have double-edged effects on renal function, which also affects intestinal homeostasis. This review aimed to clarify the interaction between gut microbiota and renal function during the onset and progression of sepsis. The mechanism of gut–kidney crosstalk may provide potential insights for the development of novel therapeutic strategies for sepsis.

Abstract
Background and aim Cis-Diamminedichloroplatinum (II) (Cisplatin) is one of the most synthetic anticancer drug but have several adverse effects and one of them is acute ren failure. Cisplatin can induce nephrotoxicity occur via the toxic generation of reactive oxygen species (ROS). Black soybean (Glycine max L. Merr.) has been reported contain high levels of phenolics and anthocyanins that has antioxidant activity. This study aims to determine the effect of ethanol extract of black soybean (EEBS) against cisplatin-induced nephrotoxicity in rats. Experimental procedure Cisplatin-induced nephrotoxicity rats treated with EEBS and the blood samples taken on days 0, 9, and 18. The effects of EEBS was evaluated by determining Interferon-γ (IFN-γ), Caspase-3 (Casp-3), and Interleukin-1β (IL-1β) expression using immunohistochemistry (IHC), blood urea nitrogen (BUN), Uric Acid (UA) content and catalase (CAT) content in the blood plasma with colorimetric assay kit. Results and conclusion Based on the results, EEBS treatment had successfully reduced pro-inflammatory cytokines IL-1β and IFN-γ, and improved physiological condition by lowering BUN and UA content while increasing CAT activity. No significant effect was found in Casp-3 expression. EEBS has potential to improve acute renal failure condition through inflammatory suppression and renal function improvement.

Abstract
AIM To examine the effect of diacerein on vascular dysfunction in type 2 diabetic rats and elucidate the mechanism of diacerein. METHODS In a rat model, type 2 diabetes was induced by high-fat diet and streptozotocin. Vascular function was assessed in vascular reactivity experiment. The effect of diacerein (10 or 20 mg/kg/day) on blood glucose, inflammation and insulin signaling, and modulators in vascular tissue in diabetic rats were investigated by molecular and biochemical approaches. RESULTS In this study, diacerein inhibited diabetes-induced vascular dysfunction. Diacerein treatment normalized blood glucose, insulin tolerance test, inflammatory cytokine levels and nitric oxide synthases expression in diabetic rats. Moreover, diacerein inhibited NF-κB and NLRP3 pathways and activated insulin signaling pathway related proteins IRS-1 and AKT in diabetic rats. CONCLUSION Diacerein improved vascular function effectively in diabetic rats by suppressing inflammation and reducing insulin resistance. These results suggest that diacerein may represent a novel therapy for patients with diabetes.

Inhibition of Inflammation and Regulation of AQPs/ENaCs/Na +-K +-ATPase Mediated Alveolar Fluid Transport by Total Flavonoids Extracted From Nervilia fordii in Lipopolysaccharide-induced Acute Lung Injury. Front Pharmacol 2021; 12:603863. [PMID: 34887746 PMCID: PMC8650715 DOI: 10.3389/fphar.2021.603863] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Accepted: 10/07/2021] [Indexed: 11/13/2022] Open
Abstract
Aims: The occurrence of vascular permeability pulmonary edema in acute lung injury (ALI) is related to the imbalance of alveolar fluid transport. Regulating the active transport of alveolar fluid by aquaporins (AQPs), epithelial sodium channels (ENaCs), and Na+-K+-ATPase can effectively reduce the edema fluid in the alveolar cavity and protect against ALI. We evaluated the therapeutic effects of total flavonoids, extracted from Nervilia fordii (TFENF), and investigated its potential mechanisms of alveolar fluid transport in a rat ALI model. Materials and methods: A model of lipopolysaccharide (LPS, 5 mg/kg)-induced ALI was established in Sprague-Dawley (SD) rats through the arteriae dorsalis penis. SD rats were divided into six groups, including the vehicle, LPS model, TFENF (6 mg/kg, 12 mg/kg, 24 mg/kg), and dexamethasone group (DEX group, 5 mg/kg). The wet-to-dry (W/D) lung weight ratio, oxygenation index, and histopathological observation were used to evaluate the therapeutic effect of TFENF. The mRNA expression of AQPs, ENaCs, and pro-inflammatory cytokines was determined using real-time polymerase chain reaction, whereas protein expression was determined using immunohistochemistry. The Na + -K + -ATPase activity was assessed using enzyme-linked immunosorbent assay. Results: LPS significantly stimulated the production of inflammatory mediators including tumor necrosis factor (TNF)-α and interleukin (IL)-1β, and disrupted the water transport balance in the alveolar cavity by inhibiting AQPs/ENaCs/Na + -K + -ATPase. Pretreatment with TFENF reduced the pathological damage and W/D ratio of the lungs and ameliorated the arterial blood oxygen partial pressure (PaO2) and oxygenation index. TFENF further decreased the mRNA level of TNF-α and IL-1β; increased the expression of AQP-1, AQP-5, αENaC, and βENaC; and increased Na + -K + -ATPase activity. Moreover, the regulation of AQPs, βENaC, and Na + -K + -ATPase and the inhibition of TNF-α and IL-1β by TFENF were found to be dose dependent. Conclusion: TFENF protects against LPS-induced ALI, at least in part, through the suppression of inflammatory cytokines and regulation of the active transport capacity of AQPs/ENaCs/Na + -K + -ATPase. These findings suggest the therapeutic potential of TFENF as phytomedicine to treat inflammation and pulmonary edema in ALI.

Abstract
Cisplatin is an antineoplastic medicine used for solid tumor treatment. The main side effect that limits its dose is nephrotoxicity. Diacerein has been used for the treatment of joint diseases like osteoarthritis. It also has exhibited analgesic effects and antipyretic activities in animal models so this study targets to indicate the diacerein effect on nephrotoxicity induced by cisplatin in rats. Rats were distributed into four groups: normal healthy control; diacerein, which received diacerein daily by gastric gavage (50 mg/kg/day); cisplatin, which received only one intraperitoneal injection of cisplatin (6 mg/kg) and cisplatin and diacerein, which received diacerein daily after the cisplatin injection till 7th and 12th days, respectively. Diacerein treatment decreased kidney function markers so the cisplatin effect was reversed. Also, diacerein increased the renal antioxidants and decreased oxidative stress. Diacerein up-regulated Ho-1 (heme oxygenase 1), Nrf2 (Nuclear factor erythroid 2–related factor 2) and endothelial nitric oxide synthase (eNOS) genes expression, while down-regulated Bcl-2-associated X protein (Bax) gene expression. Furthermore, the renal transforming growth factor beta-1 (TGF-β1) decreased by the diacerein effect. Consequently, diacerein has a curative effect against cisplatin due to its anti-inflammatory, antioxidant, and antiapoptotic properties.

Abstract
Background Severe renal ischemia-reperfusion injury results in worse outcomes of kidney transplantation. Compared to the collecting duct, the proximal tubule is more likely to exhibit severe pyroptosis and damage during renal ischemia-reperfusion. Aquaporins were reported of having regulatory roles in pyroptosis. We explored whether aquaporin 2 overexpression in proximal tubular cells could alleviate ischemia-reperfusion injury related pyroptosis. Methods A renal ischemia-reperfusion model of mice was established, and human kidney 2 cells were treated with hypoxia-reoxygenation. Aquaporin 2 overexpression was achieved in human kidney 2 cells transfected with lentivirus, which were then cultured with murine cells. Renal tissues and serum of the mice, and human kidney 2 cells were subjected to histological, molecular, and biochemical examinations. Results Compared with the sham group, the renal function of the ischemia-reperfusion group was significantly decreased, and the tissue injury was severe and accompanied by more nuclear dissolved and necrosis. Besides, the expression of aquaporin 1-5 decreased significantly, while the expression of Toll-like receptor 4, caspase-1, kim-1 and interleukin 1β and 18 increased significantly in ischemia-reperfusion group. Similar results were observed in the human kidney 2 cells test. Overexpression of aquaporin 2 partially reversed the cell damage, pyroptosis, and molecular expression changes of human kidney 2 cells induced by hypoxia-reoxygenation. Conclusions Our findings suggest that aquaporin 2 overexpression can potentially reduce pyroptosis in proximal tubular cells, and thus might be a novel target for relieving pyroptosis and injury in renal ischemia-reperfusion injury.

Abstract
Diacerein is a symptomatic slow-acting drug in osteoarthritis (SYSADOA) and the active metabolite is rhein. It is a non-steroidal anti-inflammatory drug with unique pharmacological properties as anti-oxidant and anti-apoptosis. Diacerein has recently shown to have a potential role by mediating anti-inflammatory as well as anti-oxidant and anti-apoptosis in kidney injury, diabetes mullites, and a beneficial effect on pain relief. It may have a therapeutic role in cancer, ulcerative colitis, testicular injury and cervical hyperkeratosis. Furthermore, diacerein has a valuable addition in combination therapy as a synergetic agent. This review, the first of its kind, highlights the proposed roles of diacerein in osteoarthritis and discusses recent results supporting its emerging roles with a particular focus on how these new insights may facilitate the rational development of diacerein for targeted therapies in the future.

Abstract
(1) Background: Lipopolysaccharide (LPS)-induced systemic inflammation is associated with septic acute kidney injury (AKI). We investigated the time-dependent miRNA expression changes in the kidney caused by LPS. (2) Methods: Male outbred NMRI mice were injected with LPS and sacrificed at 1.5 and 6 h (40 mg/kg i.p., early phase, EP) or at 24 and 48 h (10 mg/kg i.p., late phase, LP). The miRNA profile was established using miRCURY LNA™ microarray and confirmed with qPCR. Total renal proteome was analyzed by LC-MS/MS (ProteomeXchange: PXD014664). (3) Results: Septic AKI was confirmed by increases in plasma urea concentration and in renal TNF-α and IL-6 mRNA expression. Most miRNAs were altered at 6 and 24 h and declined by 48 h. In EP miR-762 was newly identified and validated and was the most elevated miRNA. The predicted target of miR-762, Ras related GTPase 1B (Sar1b) was downregulated. In LP miR-21a-5p was the most influenced miRNA followed by miR-451a, miR-144-3p, and miR-146a-5p. Among the potential protein targets of the most influenced miRNAs, only aquaporin-1, a target of miR-144-3p was downregulated at 24 h. (4) Conclusion: Besides already known miRNAs, septic AKI upregulated miR-762, which may regulate GTP signaling, and miR-144-3p and downregulated its target, aquaporin-1.

Abstract
Notch is a ligand-receptor interaction-triggered signaling cascade highly conserved, that influences multiple lineage decisions within the hematopoietic and the immune system. It is a recognized model of intercellular communication that plays an essential role in embryonic as well as in adult immune cell development and homeostasis. Four members belong to the family of Notch receptors (Notch1-4), and each of them plays nonredundant functions at several developmental stages. Canonical and noncanonical pathways of Notch signaling are multifaceted drivers of immune cells biology. In fact, increasing evidence highlighted Notch as an important modulator of immune responses, also in cancer microenvironment. In these contexts, multiple transduction signals, including canonical and alternative NF-κB pathways, play a relevant role. In this chapter, we will first describe the critical role of Notch and NF-κB signals in lymphoid lineages developing in thymus: natural killer T cells, thymocytes, and thymic T regulatory cells. We will address also the role played by ligand expressing cells. Given the importance of Notch/NF-κB cross talk, its role in T-cell leukemia development and progression will be discussed.

Abstract
AIMS Renal interstitial fibrosis and glomerulosclerosis are the characteristic presentation of diabetic nephropathy progression. Twist-1 overexpression contributes to renal fibrosis. Previous studies have demonstrated that pioglitazone (PIO), a PPAR-γ agonists, can ameliorate renal fibrosis and protect renal function. However, whether PIO attenuates renal fibrosis and delays diabetic nephropathy progression by regulating Twist-1 expression remains unclear. METHODS Male Zucker diabetic fatty (ZDF) rats were randomly divided into 3 groups: (1) ZDF group, (2) ZDF + PIO group treated with PIO for 10 weeks, (3) ZDF + PIO + GW9662 group treated with GW9662 (a PPAR-γ antagonist) and PIO for 10 weeks. Age-matched Zucker lean rats (ZL group) were used as a control group. Urinary albumin/creatinine ratio (UACR) and renal blood flow were measured. Renal histopathology and Twist-1 expression were determined by immunohistochemistry. The protein and mRNA levels of Twist-1 and PPAR-γ were analyzed by Western blot and qRT-PCR. RESULTS PIO considerably reduced UACR and improved renal blood flow. This was associated with amelioration of glomerulosclerosis and tubulointerstitial fibrosis evidenced by the expression decrease of collagen I, aquaporin 1, α-SMA, transforming growth factor β1 and nephrin, although glycaemia remained high. Moreover, Twist-1 protein and mRNA expression in kidney of ZDF rats were significantly increased compared with ZL rats and PIO significantly decreased Twist-1 levels. CONCLUSIONS This study shows that PIO can downregulate Twist-1 expression in the kidney, inhibit renal fibrosis and protect renal function in ZDF rats. These PIO-mediated effects are independent of glycemic control.

Abstract
Osteoarthritis (OA) is the most common degenerative disease of the cartilage and is characterized by inflammation of the synovial membrane and subchondral osteosclerosis. β1,4-galactosyltransferase-I (β1,4-GalT-I) is a crucial regulator of inflammation based on its role in the stimulation and sustenance of inflammation in OA. In the present study, we aimed at elucidating the expression pattern and potential biological activity of β1,4-GalT-I in chondrocytes isolated from OA patients. Chondrocytes were isolated from the cartilage and cultured. Western blotting and quantitative real-time polymerase chain reaction (qRT-PCR) were used to analyze β1,4-GalT-I expression. Isolated chondrocytes were stimulated with tumor necrosis factor (TNF). Our results indicate significantly enhanced expression of β1,4-GalT-I in cultivated chondrocytes upon stimulation with TNF. β1,4-GalT-I inhibited the inflammation and cell death triggered by TNF. In addition, β1,4-GalT-Iinhibited the expression of Toll-like receptor 4 (TLR4) and phosphorylation of p65 and IKK. In conclusion, our findings suggest the protective effect of β1,4-GalT-I in chondrocytes against OA induced by TNF based on its ability to block the TLR4 signaling pathway. Our results also indicate significant contribution of β1,4-GalT-I towards the anti-inflammation in the cartilage of patients suffering from OA.

Abstract
Sepsis is defined as organ dysfunction resulting from the host's deleterious response to infection. One of the most common organs affected is the kidneys, resulting in sepsis associated acute kidney injury (SA-AKI) that contributes to the morbidity and mortality of sepsis. A growing body of knowledge has illuminated the clinical risk factors, pathobiology, response to treatment, and elements of renal recovery that have advanced our ability to prevent, detect, and treat SA-AKI. Despite these advances, SA-AKI remains an important concern and clinical burden, and further study is needed to reduce the acute and chronic consequences. This review summarizes the relevant evidence, with a focus on the risk factors, early recognition and diagnosis, treatment, and long term consequences of SA-AKI. In addition to literature pertaining to SA-AKI specifically, pertinent sepsis and acute kidney injury literature relevant to SA-AKI was included.
