Nephrolithiasis is a common urological disease with high prevalence and recurrence rates. Characterizing gut microbiome profiles of nephrolithiasis patients may provide valuable insights and potential biomarkers for the disease. Therefore, we explored the relation between gut microbiome and nephrolithiasis using 16S ribosomal RNA (rRNA) gene sequencing. 13 patients with multiple kidney stones and 13 matched healthy controls were recruited. A decreasing trend in number of observed species in nephrolithiasis patients was detected, although statistical significance was not reached (p = 0...

Interleukin-6 receptor-alpha (IL6R) interacts with IL6 and forms a ligand-receptor complex, which can stimulate various cellular responses, such as cell proliferation, cell differentiation, and activation of inflammatory processes. Both genetic mutation and epigenetic modification regulate gene transcription. We identified a novel splice variant of bovine IL6R, designated as IL6R-TV, which is characterized by the skipping of exon 2 of the NCBI-referenced IL6R gene (IL6R-reference). The expression levels of IL6R-TV and IL6R-reference transcripts were lower in normal mammary gland tissues...

Uric acid has been recognised as a potential marker of endothelial dysfunction and kidney disease but there are scarce data about its importance in systemic lupus erythematosus (SLE) nephritis. This study aimed to evaluate serum uric acid (UA) levels in lupus nephritis (LN), by comparing SLE patients with normal renal function, with and without nephritis. Forty-six female SLE patients were consecutively selected and divided in two groups according to renal activity at the evaluation: presence of a recently diagnosed lupus nephritis (LN+, n = 18) and absence of lupus nephritis (LN-, n = 28)...

Sepsis, the systemic inflammatory responses after infection, remains a serious cause of morbidity and mortality in critically ill patients. The anti-malarial agent dihydroartemisinin (DHA) has been shown to be anti-inflammatory. In this study, we examined the effects of DHA on sepsis-induced acute kidney injury (AKI) and explored the mechanism underlying its mode of action in AKI. In a lipopolysaccharide (LPS)-induced mouse model, we observed that DHA treatment ameliorated glomerular injury, and relieved elevation of the urine albumin to creatinine ratio (UACR) and serum creatinine...

OBJECTIVE: Studies find both very low and high serum uric acid (UA) levels are related to oxidative stress and to conditions such as cardiovascular diseases and chronic kidney disease in the general population. Pregnancy studies have focused only on high maternal UA. In present study, we tested whether unusually high and low levels of maternal serum UA are associated with increases in blood pressure (BP) during pregnancy. STUDY DESIGN: The Pregnancy Outcomes and Community Health Study enrolled 3019 pregnant women between their 16th-27th week of pregnancy from 52 clinics in 5 Michigan communities (1998-2004)...

Trimethylamine N-oxide (TMAO) is a diet and gut microbiota-derived metabolite that has been linked to cardiovascular disease risk in human studies and animal models. TMAO levels show wide inter and intra individual variability in humans that can likely be accounted for by multiple factors including diet, the gut microbiota, levels of the TMAO generating liver enzyme Flavin-containing monooxygenase 3 (FMO3) and kidney function. We recently found that dioxin-like (DL) environmental pollutants increased FMO3 expression to elevate circulating diet-derived TMAO in mice, suggesting that exposure to this class of pollutants might also contribute to inter-individual variability in circulating TMAO levels in humans...

Systemic autoimmune diseases can affect various kinds of organs including the kidney, the skin, soft tissue and the bone. Among others, cardiovascular involvement in rheumatic diseases has been shown to affect myocardium, pericardium, cardiac vessels, conduction system and valves, eventually leading to mortality. In general, underlying chronic inflammation lead to premature atherosclerosis, but also other manifestations such as arrhythmia and heart failure may have a 'silent' progress. Traditional cardiovascular risk factors play a secondary role, while disease-specific factors (i...

Transferrin (TF), an iron-binding glycoprotein, plays an important role in host defense against pathogenic infection, which inhibits the growth and proliferation of pathogens, deprives iron from invading pathogens, and activates anti-microbial responses in macrophages. In this study, a TF homologue (OnTF) was identified from Nile tilapia (Oreochromis niloticus) and characterized at expression pattern against bacterial infection and capability binding bacterial pathogens. The open reading frame of OnTF is 2118 bp of nucleotide sequence encoding polypeptides of 705 amino acids...

The purpose of this study was primarily to evaluate the association of total fibre intake with the risk of incident chronic kidney disease (CKD). We also evaluated the association of dietary fibre from fruits, vegetables, cereals and legumes with the incidence of CKD in a population-based prospective study. We followed up 1630 participants of the Tehran Lipid and Glucose Study for 6·1 years, who were initially free of CKD. Baseline diet was assessed by a valid and reliable FFQ. Estimated glomerular filtration rate (eGFR) was calculated, using the Modification of Diet in Renal Disease Study equation, and CKD was defined as eGFR <60 ml/min per 1·73 m2...

The aim of the study is to clarify the role of hypoxia-inducible factor-1 (HIF-1) in the development of renal fibrosis in mouse obstructive nephropathy. We used mice with floxed HIF-1α alleles and tamoxifen-inducible Cre/ERT2 recombinase under ubiquitin C promoter to induce global HIF-1α deletion. Following tamoxifen administration, mice were subjected to unilateral ureteral obstruction (UUO). At 3, 7 and 14 days after UUO, renal gene expression profiles and interstitial fibrosis were assessed. HIF-1 dependent up-regulation of prolyl hydroxylase 3 and glucose transporter-1 was observed in the obstructed kidney at 3 and 7 days but not at 14 days after UUO...

Renal recovery after dialysis-requiring acute kidney injury (AKI-D) is an important clinical and patient-centered outcome. Here we examined whether the pre-admission proteinuria level independently influences risk for non-recovery after AKI-D in a community-based population. All adult members of Kaiser Permanente Northern California who experienced AKI-D between January 1, 2009 and September 30, 2015 were included. Pre-admission proteinuria levels were determined by dipstick up to four years before the AKI-D hospitalization and the outcome was renal recovery (survival and dialysis-independence four weeks and more) at 90 days after initiation of renal replacement therapy...

Multiple lines of evidence show that the anti-aging and cognition-enhancing protein Klotho fosters neuronal survival, increases the anti-oxidative stress defense, and promotes remyelination of demyelinated axons. Thus, upregulation of the Klotho gene can potentially alleviate the symptoms and/or prevent the progression of age-associated neurodegenerative diseases such as Alzheimer's disease and demyelinating diseases such as multiple sclerosis. Here we used a CRISPR-dCas9 complex to investigate single-guide RNA (sgRNA) targeting the Klotho promoter region for efficient transcriptional activation of the Klotho gene...
