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

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.

Project description:We apply developmental and single cell gene expression analysis to fetal skin of domestic cats, together with genetic characterization of Mendelian color variation, to identify when, where, and how, during fetal development, felid color patterns are established. Prior to the appearance of hair follicle placodes, we identify changes in epidermal thickness that represent a signature of color pattern establishment, and that are preceded by a pre-pattern of gene expression in which the secreted Wnt inhibitor encoded by Dickkopf 4 (Dkk4) plays a central role. We also demonstrate that mutations in Dkk4 underlie the Ticked pattern mutation in cats. Our results bring molecular understanding to how the leopard got its spots, suggest that similar mechanisms underlie periodic color pattern and periodic hair follicle spacing, and provide a genomic framework to explore natural selection for diverse pattern types in wild felids.

Project description:The purpose of this study was the identification of RNAs contained in the urinary exosome (UExo) from dogs and cats. The quality of total RNA in isolated urinary exosome (UExo)-derived total RNAs obtained from the column-based method (urine 1 mL) was checked by using a Bioanalyzer, and samples from normal renal function (NR) group and kidney disease (KD) group were pooled as one sample for each group. We collected NR dogs (n = 37), KD dogs (n = 47), NR cats (n=43), and KD cats (n = 45). For the next generation sequencing, libraries were prepared according to the manufacturer’s protocols and sequenced using 50-base reads acquired by using a HiSeq 2000 platform. The December 2011 (GRCm38/mm10) mouse (Mus musculus) genome data were used as reference. As a result, we could identify the miRNA from these samples.

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.
