Integrated landscape of renal metabolism in domestic cats with spontaneous chronic kidney disease: a multi-omics study

ABSTRACT: Chronic kidney disease (CKD) is the leading cause of mortality in aged cats. After injury, feline kidneys undergo extensive metabolic reprogramming, but a comprehensive evaluation is lacking. We integrate serum metabolome from 15 early stages, 6 late stages CKD and 14 healthy control cats, with renal cortex and medulla transcriptome and proteome. Our analysis reveals spatiotemporal patterns of gene and protein expression changes. In the early stages, there are ~2000 differentially expressed genes in the medulla, but 6 in the cortex. The number in the cortex increases to >4000 in the late stages. We provide evidence of deranged bioenergetics in CKD: circulating fatty acids and acylcarnitines accumulate, while genes and proteins involved in fatty acid transport and oxidation are downregulated. Glucose and pyruvate metabolism is altered in CKD. Impaired glutamine metabolism contributes to both energy deficiency and acid-base imbalance. Additionally, there is a downregulation of redox enzymes, and overexpression of proinflammatory and profibrotic markers in CKD. Finally, hypoxia signaling pathway is upregulated, and negatively correlated with SGLT2 expression. These data unveil profound metabolic abnormalities in feline CKD.

Integrated landscape of renal metabolism in domestic cats with spontaneous chronic kidney disease: a multi-omics study

Project description:Chronic kidney disease (CKD) is the leading cause of mortality in aged cats. After injury, feline kidneys undergo extensive metabolic reprogramming, but a comprehensive evaluation is lacking. Integration of serum metabolome from early stages, late stages CKD and healthy control cats with renal cortex and medulla transcriptome and proteome can reveal spatiotemporal patterns of gene and protein expression changes. In this study, we conducted mass spectrometry (MS)-based proteomic analysis of kidney (cortex and medulla) tissues from cats with CKD and control cats, euthanized for humane reasons unrelated to the study.

miRNA expression profiles in the serum of cats with hypertrophic cardiomyopathy compared to healthy cats

Project description:MicroRNAs negatively regulate gene expression and may serve as biomarkers for human cardiomyopathy. In the domestic cat, hypertrophic cardiomyopathy (HCM) represents the most common primary cardiomyopathy. In humans, the etiology of HCM is linked to mutations in genes of contractile muscle proteins, while in cats a clear proof for causal mutations is missing. The etiology of feline HCM is uncertain. Diagnosis is made by heart ultrasound examination and measuring the serum level of N-terminal pro B-type natriuretic peptide. The purpose of this study was to investigate whether microRNA profiles in the serum of cats with HCM are different from the profiles of healthy cats and whether specific miRNAs can be detected to serve as potential biomarkers for feline HCM or may help in understanding the etiology of this disease Blood was drawn from two groups of cats: 12 healthy cats and 11 cats suffering from hypertrophic cardiomyopathy. After clotting, samples were centrifuged and total mRNA was extracted from serum. These 23 serum samples were analyzed and the groups were compared

miRNA expression profiles in the serum of diabetic cats

Project description:BACKGROUND: MicroRNAs negatively regulate gene expression and play a pivotal role in the pathogenesis of human type 2 diabetes mellitus (T2DM). As the domestic cat presents a spontaneous animal model for human T2DM, the purpose of this study was to investigate whether microRNAs are detectable in feline serum and whether microRNA expression profiles differ between healthy and diabetic cats. METHODS: Total RNA was extracted from 400 M-BM-5l serum of healthy lean (HL) and newly diagnosed diabetic (D) cats. MicroRNA microarrays representing 1079 distinct mouse miRNA targets were used to measure miRNA expression in samples from eight HL and eight D cats. RESULTS: By microarray, 227 distinct microRNAs were identified. Nineteen miRNAs were differentially expressed in diabetic cats, but only two reached statistical significance after correction for multiple comparisons. In qRT-PCR, miR-122* was found to be upregulated in diabetic cats more than 40-fold compared to HL cats, while miR-193b was upregulated about 10-fold. MiR-483* showed a 6- fold increase in diabetic cats compared to HL cats. CONCLUSIONS: Small volumes of serum samples yield sufficient material to detect altered microRNA expression profiles in diabetic cats. The domestic cat may be considered a useful animal model for studying miRNAs involved in human T2DM. Blood was drawn from two groups of cats: 8 healthy cats and 8 cats suffering from diabetes. After clotting, samples were centrifuged and total mRNA was extracted from serum. These 16 serum samples were analyzed and the groups were compared. Due to technical problems during hybridization (leaking chamber), sample 1_4_B (Serum_diabetic_8) was not included into analysis.

Host RNA dynamics in cats with feline infectious peritonitis

Project description:Feline infectious peritonitis (FIP) is a fatal disease, if left untreated, caused by feline coronavirus (FCoV). Although the role of the immune system in the pathogenesis of FIP remains incompletely understood, an excessive and harmful immune response appears to be a key factor. In a recent study by the same authors, 18 cats with FIP were successfully cured with oral GS-441524. The present study aimed to analyze the molecular signatures of these treated cats using next-generation RNA-sequencing on full blood samples by highlighting key immune pathways involved in disease progression, treatment response, and recovery. Therefore, samples were analyzed at three stages: untreated (d0), treated with the antiviral drug (days 2, 7, 28), and fully cured (days 168, 252, 365). Additionally, gene expression profiles were compared to those of healthy FCoV-infected control cats (n=12) and uninfected healthy control cats (n=5). Multiple tests with adjusted p-value (adj.p<0.001) were performed. Within the first few days of treatment, massive changes in the RNA signature profile were observed, with approximately 75% of expressed genes significantly differentially regulated between d0 and later time points. Notably, a strong antiviral immune response, which was dominant at the onset of the disease, was significantly downregulated within two days, accompanied by a shift in blood cell composition from monocytes and neutrophils to B cells. Our findings revealed a rapid normalization of the blood RNA signature within the first week of treatment suggesting that elimination of the virus from the blood leads to a rapid down-regulation of the damaging immune response.

Comparative Transcriptome Analysis of PBMCs in Cats Diagnosed with and Recovered from FIPV

Project description:Background Feline infectious peritonitis is a viral disease caused by feline coronavirus an enveloped virus with a single-stranded RNA genome that is approximately 30 kb long. Although FCoV generally causes mild symptoms, approximately 5 % of cases progress to death in cats worldwide. FCoV shares certain virological features with severe acute respiratory syndrome coronavirus 2 that causes COVID-19, indicating that common therapeutic strategies may be applicable. GS-441524 the parent drug of remdesivir and a competitive inhibitor of nucleoside triphosphates in viral RNA synthesis is a well-known treatment for FIP. However, comparative transcriptome and gene ontology analyses of normal (Normal), FIP-diseased (FIPD), and FIP-recovered (FIPR) cats have not yet been conducted. Results In this study, we compared the mRNA expression profiles of peripheral blood mononuclear cells from Normal, FIPD, and FIPR cats to identify immunological alterations. We identified 715 (FIPD/Normal) and 1,164 (FIPR/FIPD) differentially expressed genes with statistical significance. These data were input into the bioinformatics program. As a result, the analysis revealed statistically significant and contrasting patterns of canonical pathways of neutrophil degranulation and interleukin-8 (IL-8) signaling pathways. Additionally, we observed that kruppel-like factor 6 (KLF6) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) were upstream molecules of IL-8, promoting neutrophil activation and function. Conclusions This study identified immunological alterations in PBMCs of Normal, FIPD, and FIPR cats. KLF-6 and NF-κB were found to regulate IL-8-mediated neutrophil activation.
