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:This study is to identify urinary exosome microRNAs (miRNAs) that are unique to premature ovarian insufficiency (POI) with and without Turner syndrome and to use them as diagnostic markers for POI patients. We examined the miRNAexpression profile in urine exosomes from POI patients with and without Turner syndrome.

Project description:The aim of the study was to analyse differences in serum and urinary proteomes between healthy dogs and dogs with renal dysfunction in babesiosis using label-based high-resolution quantitative proteomic approach. In the study 8 healthy control dogs (group H) and 22 dogs with naturally occurring babesiosis were enrolled. Dogs with babesiosis were divided into 3 groups: group A consisted of 6 non-azotaemic dogs (serum creatinine <140 μmol/L) with normal UPC (UPC < 0.5), group B of 10 non-azotaemic dogs with proteinuria (UPC > 0.5) and group C of 6 azotaemic dogs (serum creatinine > 140 μmol/L) and significant proteinuria (UPC > 2).

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:Exosome-derived miRNAs are regarded as biomarkers for the diagnosis and prognosis of many human cancers. However, its function in clear cell renal cell carcinoma (ccRCC) remains unclear. In this study, differentially expressed miRNAs from urinal exosomes were identified using next-generation sequencing (NGS) and verified using urine samples of ccRCC patients and healthy donors. Then the exosomes were analyzed in early-stage ccRCC patients, healthy individuals and patients suffering with other urinary system cancers. Afterwards, the target gene of the miRNA was detected. Its biological function was investigated in vitro and in vivo. The results showed that miR-30c-5p could be stably amplified. Its expression pattern was significantly different only between ccRCC patients and healthy control individuals, but not compared with that of other urinary system cancers, which indicated its ccRCC specificity. Additionally, the overexpression of miR-30c-5p inhibited ccRCC progression in vitro and in vivo. Heat shock Protein 5 (HSPA5) was found to be a direct target gene of miR-30c-5p. HSPA5 depletion caused by miR-30c-5p inhibition reversed the promoting effect of ccRCC growth. In conclusion, urinary exosomal miR-30c-5p acts as a potential diagnostic biomarker of early-stage ccRCC, and might modulate the expression of HSPA5, which is correlated with the progression of ccRCC.
