We aimed to characterize the time-course of changes after contralateral nephrectomy (Nx) in a model of unilateral ischemic AKI-induced CKD with good translational utility. (2) Methods: Severe (30 min) left renal ischemia-reperfusion injury (IRI) or sham operation (S) was performed in male Naval Medical Research Institute (NMRI) mice followed by Nx or S one week later. Expression of proinflammatory, oxidative stress, injury and fibrotic markers was evaluated by RT-qPCR. (3) Results: Upon Nx, the injured kidney hardly functioned for three days, but it gradually regained function until day 14 to 21, as demonstrated by the plasma urea. Functional recovery led to a drastic reduction in inflammatory infiltration by macrophages and by decreases in macrophage chemoattractant protein-1 (MCP-1) and tumor necrosis factor-alpha (TNF-α) mRNA and most injury markers. However, without Nx, a marked upregulation of proinflammatory (TNF-α, IL-6, MCP-1 and complement-3 (C3)); oxidative stress (nuclear factor erythroid 2-related factor 2, NRF2) and fibrosis (collagen-1a1 (Col1a1) and fibronectin-1 (FN1)) genes perpetuated, and the injured kidney became completely fibrotic. Contralateral Nx delayed the development of renal failure up to 20 weeks. (4) Conclusion: Our results suggest that macrophage activation is involved in postischemic renal fibrosis, and it is drastically suppressed by contralateral nephrectomy ameliorating progression.}, keywords = {Inflammation; MICE; chronic kidney disease; TNF-α; acute kidney injury; MCP-1}, year = {2020}, eissn = {1422-0067}, orcid-numbers = {Tod, Pál/0000-0001-9163-7071; Róka, Beáta/0000-0002-1491-1644; Kaucsár, Tamás/0000-0003-4460-1265; Fintha, Attila/0000-0002-0519-8170; Krenács, Tibor/0000-0001-9164-065X; Szénási, Gábor/0000-0002-7350-6091; Hamar, Péter/0000-0002-1095-3564} } @article{MTMT:31291830, title = {Podocyte RNA sequencing reveals Wnt- and ECM-associated genes as central in FSGS}, url = {https://m2.mtmt.hu/api/publication/31291830}, author = {Bukosza, Éva Nóra and Kratochwill, Klaus and Kornauth, Christoph and Schachner, Helga and Aufricht, Christoph and Gebeshuber, Christoph A.}, doi = {10.1371/journal.pone.0231898}, journal-iso = {PLOS ONE}, journal = {PLOS ONE}, volume = {15}, unique-id = {31291830}, issn = {1932-6203}, year = {2020}, eissn = {1932-6203} } @article{MTMT:31257752, title = {ECM Characterization Reveals a Massive Activation of Acute Phase Response during FSGS.}, url = {https://m2.mtmt.hu/api/publication/31257752}, author = {Bukosza, Éva Nóra and Kornauth, Christoph and Hummel, Karin and Schachner, Helga and Huttary, Nicole and Krieger, Sigurd and Nöbauer, Katharina and Oszwald, André and Razzazi Fazeli, Ebrahim and Kratochwill, Klaus and Aufricht, Christoph and Szénási, Gábor and Hamar, Péter and Gebeshuber, Christoph A}, doi = {10.3390/ijms21062095}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {21}, unique-id = {31257752}, issn = {1661-6596}, abstract = {The glomerular basement membrane (GBM) and extra-cellular matrix (ECM) are essential to maintain a functional interaction between the glomerular podocytes and the fenestrated endothelial cells in the formation of the slit diaphragm for the filtration of blood. Dysregulation of ECM homeostasis can cause Focal segmental glomerulosclerosis (FSGS). Despite this central role, alterations in ECM composition during FSGS have not been analyzed in detail yet. Here, we characterized the ECM proteome changes in miR-193a-overexpressing mice, which suffer from FSGS due to suppression of Wilms' tumor 1 (WT1). By mass spectrometry we identified a massive activation of the acute phase response, especially the complement and fibrinogen pathways. Several protease inhibitors (ITIH1, SERPINA1, SERPINA3) were also strongly increased. Complementary analysis of RNA expression data from both miR-193a mice and human FSGS patients identified additional candidate genes also mainly involved in the acute phase response. In total, we identified more than 60 dysregulated, ECM-associated genes with potential relevance for FSGS progression.

Only a subset of patients responds to current therapies, making it important to identify alternative therapeutic options. The interleukin (IL)-1 receptor antagonist anakinra is beneficial in several diseases with renal involvement. Here, we evaluated the potential of anakinra for FSGS treatment. Molecular process models obtained from scientific literature data were used to build FSGS pathology and anakinra mechanism of action models by exploiting information on protein interactions. These molecular models were compared by statistical interference analysis and expert based molecular signature matching. Experimental validation was performed in Adriamycin- and lipopolysaccharide (LPS)-induced nephropathy mouse models. Interference analysis (containing 225 protein coding genes and 8 molecular process segments) of the FSGS molecular pathophysiology model with the drug mechanism of action of anakinra identified a statistically significant overlap with 43 shared molecular features that were enriched in pathways relevant in FSGS, such as plasminogen activating cascade, inflammation and apoptosis. Expert adjudication of molecular signature matching, focusing on molecular process segments did not suggest a high therapeutic potential of anakinra in FSGS. In line with this, experimental validation did not result in altered proteinuria or significant changes in expression of the FSGS-relevant genes COL1A1 and NPHS1. In summary, an integrated bioinformatic and experimental workflow showed that FSGS relevant molecular processes can be significantly affected by anakinra beyond the direct drug target IL-1 receptor type 1 (IL1R1) context but might not counteract central pathophysiology processes in FSGS. Anakinra is therefore not suggested for extended preclinical trials.}, year = {2019}, eissn = {1932-6203}, orcid-numbers = {Herzog, Rebecca/0000-0003-1946-7770; Kratochwill, Klaus/0000-0003-0803-614X} } @article{MTMT:30789521, title = {Glomerular Collagen Deposition and Lipocalin-2 Expression Are Early Signs of Renal Injury in Prediabetic Obese Rats}, url = {https://m2.mtmt.hu/api/publication/30789521}, author = {Bukosza, Éva Nóra and Kaucsár, Tamás and Godó, Mária and Lajtár, Enikő and Tod, Pál and Koncsos, Gábor and Varga, Zoltán and Baranyai, Tamás and Nguyen, Minh Tu and Schachner, Helga and Sőti, Csaba and Ferdinandy, Péter and Giricz, Zoltán and Szénási, Gábor and Hamar, Péter}, doi = {10.3390/ijms20174266}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {20}, unique-id = {30789521}, issn = {1661-6596}, abstract = {Feeding rats with high-fat diet (HFD) with a single streptozotocin (STZ) injection induced obesity, slightly elevated fasting blood glucose and impaired glucose and insulin tolerance, and caused cardiac hypertrophy and mild diastolic dysfunction as published before by Koncsos et al. in 2016.

HFD and STZ increased body weight and visceral adiposity and plasma leptin concentration. Despite hyperleptinemia, plasma C-reactive protein concentration decreased in PRED rats. Immunohistochemistry revealed elevated collagen IV protein expression in the glomeruli, and Lcn2 mRNA expression increased, while Il-1β mRNA expression decreased in both the renal cortex and medulla in PRED vs. CON rats. Kidney histology, urinary protein excretion, plasma creatinine, glomerular Feret diameter, desmin protein expression, and cortical and medullary mRNA expression of TGF-β1, Nrf2, and PPARγ were similar in CON and PRED rats. Reduced AMPKα phosphorylation of the autophagy regulator Akt was the first sign of liver damage, while plasma lipid and liver enzyme concentrations were similar.

Proteomic analyses of EEV fractions identified > 1,700 cargo proteins and revealed a dominant motility-promoting protein signature.
