Serum proteome profiling across different stages of myxomatous mitral valve disease in domestic dogs

ABSTRACT: Development and progression of myxomatous mitral valve disease (MMVD) in domestic dogs is unpredictable and pathobiology still unclear. The American College of Veterinary Internal Medicine (ACVIM) perceived that mayor improvement in management of diseased dogs would be timely diagnosis, especially detection of transition from MMVD stage B1 into B2. Thus, in this study we compared by tandem mass tag (TMT) protocol and mass spectrometry (MS) acquired quantitative proteome profiles of serum collected from healthy (control) (N=12) and dogs diagnosed with different stages of naturally occurring MMVD: B1 (N=13), B2 (N=12) and C (N=13). Prior to proteomic analysis dogs were distinguished into experimental categories based on echocardiography results. Serum biochemistry and concentrations of three cardiac biomarkers (galectin-3, suppression of tumorigenicity 2 and asymmetric dimethylarginine) were performed to obtain better characterization of healthy/control group and MMVD cases.

Canine myxomatous mitral valve disease (MMVD) is similar to Barlow's form of MMVD in humans. These valvulopathies are complex, with varying speeds of progression. We hypothesized that the relative abundances of serum proteins would help identify the consecutive MMVD stages and discover new disease pathways on a systemic level. To identify distinction-contributing protein panels for disease onset and progression, we compared the proteomic profiles of serum from healthy dogs and dogs with differen ...[more]

Project description:Bovine mastitis, the infection of the mammary gland which leads to great health and economic challenges for dairy farmers is accompanied by dramatic changes in the milk proteome. In this study of naturally occurring mastitis not only have the changes in the milk proteome been quantified in subclinical and clinical mastitis but simultaneous changes in the serum proteome have also been characterised and quantified. Milk and serum samples from healthy dairy cows (n=12) were compared to those of cows with subclinical (n=10) and clinical mastitis (n=112) using TMT label-based proteomic approach. The study included the milk and serum samples taken from thirty-two dairy cows ( kept on private farms located in Croatia. All cows were checked by physical examination. Somatic cells count (SCC) and mastitis test in milk samples were performed. According to the results, cows were assigned into three groups: Group I (control, n=10) consisted of healthy cows with SCC below 400,000 cells/ml on the monthly check-up and a negative mastitis test and without any clinical sign of mastitis. Group II (subclinical mastitis, n=12) comprised cows without clinical signs of mastitis but with SCC above 400,000 cells/ml on the monthly basis and a positive mastitis test at the time of sampling. Group III (clinical mastitis, n=10) consisted of cows with clinical signs of mastitis which include changes in milk appearance (flakes and clots in milk), different stages of udder inflammation (hyperemia, edema, pain, udder enlargement and elevated udder temperature) and disturbance of general health (depression, relaxed cold ears, dehydration, elevated body temperature, increased heart and respiratory rate, decreased ruminal contraction and decreased appetite). Blood samples were taken from v. coccygea and centrifuged at 3000 g for 15 min after clotting for two hours at room temperature. Serum samples were stored at -80°C until analysis. Milk samples were taken aseptically before the morning milking. First few streams were discarded. Teat ends were disinfected with cotton swabs soaked with 70% ethanol. Samples were taken into sterile tubes and transported to laboratory on ice within a few hours.
