Single-nucleus atlas of the human kidney papilla identifies significant immune injury in patients with stone disease

Project description:Kidney stone disease causes significant morbidity and increases health care utilization. In this dataset, we applied a single-nucleus assay to renal papila samples in order to charachterize the cellular and molecular niches in patients with calcium oxalate (CaOx) stone disease and healthy subjects. In addition to identifying cell types important in papillary physiology, we characterize collecting duct cell subtypes and an undifferentiated epithelial cell type that was more prevalent in stone patients. Despite the focal nature of mineral deposition in nephrolithiasis, we uncover a global injury signature characterized by immune activation, oxidative stress and extracellular matrix remodeling. We also identify the association of MMP7 and MMP9 expression with stone disease and mineral deposition, respectively. MMP7 and MMP9 are significantly increased in the urine of patients with CaOx stone disease, and their levels correlate with disease activity. Our results define the spatial molecular landscape and specific pathways contributing to stone-mediated injury in the human papilla and identify associated urinary biomarkers.

Microarray analysis of long noncoding RNA and mRNA expression profiles in Randall’s Plaques of CaOx stones patients

Project description:Microarray analysis was used to assess the expression levels of lncRNAs and mRNAs in three pairs of Randall’s plaques tissues of CaOx renal stones patients and normal renal papillary tissues.Randall’s Plaques tissues of CaOx renal stones patients were obtained from patients with idiopathic CaOx renal stone who underwent percutaneous nephrolithotomy. Normal renal papillary tissues were obtained from patients with renal tumor who underwent nephrectomy, the tissues were obtained from papillary without tumor invasion. Randall’s Plaques tissues of CaOx renal stones patients were obtained from patients with idiopathic CaOx renal stone who underwent percutaneous nephrolithotomy.

Oxidative modifications of urinary proteins increase kidney stone risk

Project description:Clinical and animal studies have demonstrated the increasing evidence of oxidative stress in kidney stone disease. Recent findings have shown that the interactions between calcium oxalate (CaOx) crystals and renal tubular cells can promote many cellular events such as cell proliferation, cell death, cellular injury, mitochondrial dysfunction and inflammatory cascade. All of these cellular events are associated with oxidative stress and overproduction of free radicals and reactive oxygen species (ROS) such as superoxide and hydrogen peroxide in renal tubular cells. However, almost all of these references have shown that oxidative stress occurs after the causative crystals have been deposited in the kidney or exposed to renal tubular cells, whereas its primary role as the etiology remained unclear. In this study, we examined effects of oxidative modifications of urinary proteins on CaOx stone formation processes. Urinary proteins were modified by performic oxidation and the presence of oxidatively modified urinary proteins was verified, quantified and characterized by Oxyblot assay and tandem mass spectrometry (nanoLC-ESI-LTQ-Orbitrap-MS/MS). Subsequently, activities of oxidatively modified urinary proteins on CaOx stone formation processes were examined.

In vitro stimulation of mouse spleen cells by mouse urine

Project description:Urinary tract-associated lymphoid structures (UTLASs), tertiary lymphoid tissues, are formed in renal pelvis (RP) of humans and mice with chronic kidney disease. We found that UTALS development was accelerated by urine leakage from RP lumen to the parenchyma following dysfunction of transitional epithelium covering UTLASs. Thus, UTALS-forming cells were stimulated by urine including urinary bio active substances.

Abnormal metabolism of palmitic acid promotes the formation of renal calcium oxalate stones

Project description:Individual metabolic factors are involved in the occurrence and development of CaOx stones, and dyslipidemia is an independent risk factor for the formation of urolithiasis. This study have screened out palmitic acid as one of the significantly differential metabolites in the urine of patients with renal CaOx stones compared with healthy controls by metabolomics. This study aims to further clarify the correlation between abnormal palmitic acid metabolism and the formation of renal CaOx stones, confirm the promoting effect of abnormal palmitic acid metabolism on the adhesion of CaOx crystals and the formation of renal CaOx stones

Compared gene expression between kidney and renal pelvis

Project description:Tertiary lymphoid tissues (TLTs) are formed in systemic organs manifesting chronic inflammation. Herein, we found that the renal pelvis (RP) could form urinary tract-associated lymphoid tissues (UTALTs) in a TLT-formation manner in humans and mice with chronic kidney disease (CKD), regardless of infectious pyelonephritis. Our results demonstrated that urine is crucial for UTALT development. Urine leak from the lumen into the parenchyma of the RP through an altered transitional epithelium (TE) barrier, stimulated RP stromal cells immunologically and attracted immune cells via cytokine and chemokine production. Pathophysiological crosstalk was observed between UTALT development and tubulointerstitial lesions and TLT formation in the kidney.
