Abstract
INTRODUCTION Focal segmental glomerulosclerosis (FSGS) is characterized by focal and segmental obliteration of glomerular capillary tufts with increased matrix and usually associated with nephrotic range proteinuria. FSGS is a huge burden to society; however, the mechanisms remain unclear and treatment is still lacking. METHODS Adriamycin nephropathy was induced by Adriamycin injection and some mice were also injected with Anti-miR-155-5p LNA or YC-1 (a pharmacological inhibitor of HIF-1). At 6 weeks, the mice were sacrificed, and kidneys, blood and urine samples were collected for further analysis. RESULTS We demonstrated a significant increase of miR-155-5p in kidney tissues in Adriamycin-induced FSGS mouse models. We also found Adriamycin treatment led to the activation of HIF-1, and inhibition of HIF-1 using YC-1 partly prevented the induction of miR-155-5p. Functionally, anti-miR-155-5p attenuated kidney injury and delayed the progression of renal fibrosis. Further, anti-miR-155-5p also enhanced the expression of Nrf2 following Adriamycin treatment. Further, our luciferase microRNA target reporter assay verified Nrf2 as a direct target of miR-155-5p. Our further results indicated anti-miR-155-5p could suppress kidney oxidative stress and inflammation, also supporting Nrf2 was the direct target of miR-155-5p. Finally, we also found miR-155-5p did not increase in serum but significantly increased in urine, indicating urinary miR-155-5p may be useful for FSGS diagnosis. CONCLUSION This study identified a HIF-1/miR-155-5p/Nrf2 axis which can promote kidney oxidative stress and inflammation, finally aggravating kidney injury and accelerating the progression of renal fibrosis in FSGS. Moreover, the increase in urinary miR-155-5p may be useful for the diagnosis of FSGS.

STAT-3 signaling role in an experimental model of nephropathy induced by doxorubicin. Mol Cell Biochem 2022; 478:981-989. [PMID: 36201104 DOI: 10.1007/s11010-022-04574-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Accepted: 09/23/2022] [Indexed: 01/10/2023]
Abstract
The focal segmental glomerulosclerosis (FSGS) is one of the most frequent glomerulopathy in the world, being considered a significative public health problem worldwide. The disease is characterized by glomerular loss mainly due to inflammation process and collagen fibers deposition. STAT-3 is a transcription factor associated with cell differentiation, migration and proliferation and in renal cells it has been related with fibrosis, acting on the progression of the lesion. Considering this perspective, the present study evaluated the involvement of STAT-3 molecule in an experimental model of FSGS induced by Doxorubicin (DOX). DOX mimics primary FSGS by causing both glomerular and tubular lesions and the inhibition of the STAT3 pathway leads to a decrease in fibrosis and attenuation of kidney damage. We described here a novel FSGS experimental model in a strain of genetically heterogeneous mice which resembles the reality of FSGS patients. DOX-injected mice presented elevated indices of albuminuria and glycosuria, that were significantly reduced in animals treated with a STAT-3 inhibitor (STATTIC), in addition with a decrease of some inflammatory molecules. Moreover, we detected that SOCS-3 (a regulator of STAT family) was up-regulated only in STATTIC-treated mice. Finally, histopathological analyzes showed that DOX-treated group had a significant increase in a tubulointerstitial fibrosis and tubular necrosis, which were not identified in both control and STATTIC groups. Thus, our results indicate that STAT-3 pathway possess an important role in experimental FSGS induced by DOX and may be an important molecule to be further investigated.

Abstract
The reported cases describe the association between collapsing focal segmental glomerulosclerosis (FSGS) and acute dengue virus infection. In both cases, patients were diagnosed with dengue virus infection and had a severe kidney disease, with nephrotic syndrome and acute kidney injury. Kidney biopsy was performed and showed collapsing FSGS. The first patient, a 27-year-old man, was diagnosed with dengue virus infection and developed nephrotic syndrome after two weeks of illness. He was treated with methylprednisolone for three days and intravenous furosemide. This patient evolved well, although his renal function did not fully recover. The second patient, a 32-year-old man, was diagnosed with a milder clinical presentation of dengue virus infection. He had a past medical history of nephrotic syndrome in childhood, which might have caused its relapse. This patient was treated with intravenous furosemide and also did not fully recover renal function. These cases highlight the possible implication of dengue virus infection in the etiology of collapsing variant of FSGS. Healthcare professionals should be prepared to identify similar cases.

Abstract
Hereditary nephropathy is a progressive fatal renal disease caused by genetic changes. In this study, genetic screening was used to reveal mutations in a family in Southern China, in which there are two patients with confirmed hereditary nephropathy, who are alive at the time of publication. Imaging tests, including color Doppler ultrasonography and magnetic resonance imaging (MRI), as well as pathological examinations, including hematoxylin-eosin staining, electron microscopy and immunohistochemistry were performed. Target sequencing of nephrosis 2 (NPHS2), wilms tumor 1 (WT1), phospholipase C ε 1 (PLCE1), actinin α 4 (ACTN4), angiotensin I converting enzyme (ACE), uromodulin (UMOD) and nephrocystin 1 (NPHP1) was also carried out. This study indicated that heterozygous genetic variants of NPHS2, WT1, ACTN4, PLCE1 and UMOD found in the patients were gene polymorphisms. A renal biopsy showed sclerosing glomerulonephritis, dilated tubules and lymphocyte/monocyte infiltration in the interstitium of the index patients. Genetic analysis showed vertical transmission of the disease-causing mutations, including a homozygous deletion in NPHP1 and a nonsense mutation in ACE found via PCR-based single nucleotide polymorphism screening. Further network analysis identified direct and indirect co-location genes between NPHP1 and ACE. To conclude, familial adolescent nephronophthisis was diagnosed in two index patients in this study. It is recommended that comprehensive gene mutation screening is used in the diagnosis of complex hereditary diseases.

Abstract
Background The collapsing variant of focal segmental glomerulosclerosis (FSGS) is the most aggressive form of FSGS and is characterized by at least one glomerulus with segmental or global collapse and overlying podocyte hypertrophy and hyperplasia. Viruses can act as aetiological agents of secondary FSGS. This study aims to establish an aetiological link between dengue virus (DENV) infection and the collapsing variant of FSGS and to analyse possible influences of the apolipoprotein 1 (APOL1) gene risk alleles on the disease. Methods Biopsies and medical records were gathered from 700 patients of the Instituto de Nefropatologia, Belo Horizonte, Brazil. Screening for the collapsing variant of FSGS was performed and serological, immunohistochemical, tissue polymerase chain reaction (PCR) and genetic analysis were conducted. Results Eight patients were identified with positive DENV serology and negative serological and/or tissue markers for hepatitis B virus, hepatitis C virus, Epstein–Barr virus, human immunodeficiency virus, cytomegalovirus and parvovirus B19. In PCR analysis, six patients had positive markers for DENV strain genetic material, one patient had positive markers for co-infection of Zika virus (ZIKV) and DENV and one patient had positive markers only for ZIKV infection. Six of the eight patients did not show risk alleles of the APOL1 gene. One patient had only one risk allele (G1) and the sample from another did not contain enough DNA for genetic analysis to be performed. Conclusions This study provided strong evidence that DENV can infect renal tissue and possibly functions as a second hit to the development of the collapsing variant of FSGS. Nonetheless, this study also highlights the possible implication of ZIKV infection in FSGS and supports the argument that risk alleles of the APOL1 gene may not be implicated in the susceptibility to FSGS in these patients.

Abstract
BACKGROUND Low birth weight (LBW) is associated with reduced nephron endowment. Clinical-pathologic features of post adaptive focal segmental glomerulosclerosis (FSGS) have been observed in subjects with prematurity and very LBW. METHODS We aimed to investigate the correlation between LBW and outcome in a cohort of 89 children with idiopathic nephrotic syndrome (NS) (2-12 years-old at onset, followed for > 3 years), of whom 21 with LBW (birth weight < 10th percentile for gestational age, gender, ethnicity, and maternal parity or birth weight < 2500 g). RESULTS Children with NS and LBW were found to have FSGS more frequently than children with normal birth weight (NBW) [8/21 = 38% vs. 4/68 = 6%; odds ratio, OR 7.754 (95% confidence interval, CI 2.184-27.525); χ2 = 9.817; p < 0.003]. Children with LBW and cortico-sensitive NS had a greater risk of cortico-dependence (CD) than those with NBW [10/13 = 76.9% vs. 28/63 = 44.4%, OR 4.744 (1.188-18.936); χ2 = 4.158; p < 0.05]. Moreover, children with LBW and CDNS needed a greater dose of immunosuppressive drugs than those with NBW [OR 4 (1.153-13.877); χ2 = 3.842; p = 0.05]. CONCLUSIONS LBW children developing NS had higher risk of FSGS and CD, and needed heavier immunosuppressive therapy than those with NBW. These data might suggest a conditioning role for hemodynamic and podocyte changes due to reduced nephron mass in LBW.

Abstract
Background/Aim: Focal segmental glomerulosclerosis (FSGS) typically presents with nephrotic range proteinuria, which could eventually develop into end-stage renal disease. Resveratrol (RSV) is a natural polyphenol compound, which has been reported to suppress inflammatory response and renal interstitial fibrosis. This study is aimed at evaluating the renoprotective effect of RSV treatment on adriamycin-induced FSGS. Methods: In Balb/c mice, adriamycin nephropathy was induced by adriamycin (10 mg/kg body weight, diluted in normal saline) via a tail vein on day 0. Then the mice were treated with RSV (40 mg/kg body weight) once daily by oral gavage, again starting on the day of adriamycin injection and continued for 6 weeks. At 6 weeks, the mice were sacrificed; kidneys and blood samples were collected for further analysis. Results: When treated with adriamycin, the expressions of C3aR, C5aR, sphingosine kinase 1 (Sphk1), and soluble urokinase-type plasminogen activator receptor (suPAR) were upregulated, while RSV treatment could inhibit the expressions of C3aR, C5aR, Sphk1, and suPAR, eventually leading to anti-inflammatory and anti-fibrosis conditions. Conclusion: RSV attenuates adriamycin-induced FSGS through C3aR/C5aR-Sphk1 pathway.

Abstract
Background The European Veterinary Renal Pathology Service (EVRPS) is the first Web‐based registry for canine renal biopsy specimens in Europe. Hypothesis/Objectives The aim was to verify whether differences exist between the clinical and laboratory presentation of dogs with nephropathy according to renal pathological findings, as defined by light and electron microscopy of renal biopsy specimens submitted to EVRPS. Animals Renal biopsy specimens of dogs were collected from the archive of the service (n = 254). Cases were included if both light and electron microscopy were available (n = 162). Methods Renal biopsy specimens were classified based on the morphological diagnoses. Thereafter, they were grouped into 3 disease categories, including immune‐complex‐mediated glomerulonephritis (ICGN), non‐immune‐complex‐mediated GN (non‐ICGN), and renal lesions not otherwise specified (RL‐NOS). Differences among morphological diagnoses and among disease categories were investigated for clinical and laboratory variables. Results Serum albumin concentration was lower in dogs with ICGN than in those with non‐ICGN (P = 0.006) or RL‐NOS (P = 0.000), and the urine protein‐to‐creatinine ratio (UPC) was significantly higher in ICGN than in the other 2 disease categories. Regarding morphological diagnoses, albumin was significantly lower in amyloidosis (AMY) and membranous (MGN), membranoproliferative (MPGN) or mixed glomerulonephritis (MixGN) than in minimal change disease, primary (FSGS I) or secondary (FSGS II) focal and segmental glomerulosclerosis and juvenile nephropathies (JN). The UPC was higher in MPGN than in FSGS I and FSGS II. Conclusions and clinical importance Dogs with ICGN, in particular MPGN, had higher protein loss than those with non‐ICGN or RL‐NOS, leading to more severe hypoalbuminemia. Clinical and laboratory differentiation among dogs with the different morphological diagnoses and among dogs with different disease categories was difficult due to overlapping results.
