Item Adiponectin and IGF-1 are negative acute phase proteins in a dog model of acute endotoxaemia(Elsevier, 2011-03-15) Tvarijonaviciute, Asta; Ceron, Jose J.; Eralp, Oya İnan; Kocatürk, Meriç; Yılmaz, Zeki; Uludağ Üniversitesi/Veterinerlik Fakültesi/Dahiliye Anabilim Dalı.; 0000-0002-4242-8609; 0000-0001-9836-0749; AAG-2943-2020; 24472964600; 36437200800; 35944810500The objective of this study was to evaluate the influence of an experimentally induced acute inflammation on serum adiponectin and insulin-like growth factor 1 (IGF-1) levels in the dog, and to compare their evolution with other well-established acute phase proteins (APPs) such as C-reactive protein (CRP), and haptoglobin (Hp). Therefore levels of adiponectin, IGF-1 and a profile of APPs were measured in healthy dogs after intravenous administration of E. coli LPS (0.02 mg/kg) and compared with dogs injected with saline solution (0.2 mL/kg). Adiponectin and IGF-1 were both decreased in response to endotoxins in the dog. Significant positive correlations were found between adiponectin and IGF-1 (r = 0.31; p < 0.05). Adiponectin had also a significant negative correlation with CRP (r = 0.39; p < 0.05) and Hp (r = -0.27; p < 0.05), whereas IGF-1 had significant negative correlation with CRP (r = -0.52; p < 0.001). The results obtained in the present study indicate that adiponectin and IGF-1 behave as negative acute phase proteins after acute inflammatory stimulus in dogs.Publication Changes in choline and cholinesterase in saliva of dogs with parvovirus infection(Elsevier, 2021-01-01) Kocatürk, Meriç; Tecles, Fernando; Yalçın, Ebru; Cihan, Hüseyin; Tural, Merve; Levent, Pınar; Cansev, Mehmet; Ceron, Jose J.; Yılmaz, Zeki; KOCATÜRK, MERİÇ; YALÇIN, EBRU; CİHAN, HÜSEYİN; Tural, Merve; Levent, Pınar; CANSEV, MEHMET; YILMAZ, ZEKİ; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/İç Hastalıkları Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Farmakoloji Anabilim Dalı.; 0000-0002-2849-1222; 0000-0001-6703-4908; 0000-0003-2918-5064; 0000-0001-9836-0749; M-9071-2019; GDR-9018-2022 ; V-5578-2017; ACP-9956-2022; A-9637-2008; ABH-3742-2020; DDR-1481-2022This study investigated the changes in choline (Ch) and butyrylcholinesterase (BChE) in saliva in canine parvovirosis (CP) as a model of sepsis, and their correlations with these analytes in serum and with other markers of inflammation such as white blood cell count (WBC) and serum C-reactive protein (CRP). A total of 30 dogs with CP were sampled for saliva and serum at presentation, and 10 healthy puppies were also sampled as controls. Salivary Ch was higher in dogs with CP (P < 0.001) showing a positive correlation with CRP, whereas no differences were observed in salivary BChE. This is the first report in which Ch is measured in saliva of dogs and based in the results of this study, salivary Ch could be potentially used as biomarker of the severity of CP.Item Identification of novel biomarkers for treatment monitoring in canine leishmaniosis by high-resolution quantitative proteomic analysis(Elsevier, 2017-08-08) Martinez, Subiela Silvia; Horvatic, Anita; Escribano, Damian; Pardo, Luis Marin; Mrljak, Vladimir; Burchmore, Richard; Ceron, Jose J.; Kocatürk, Meriç; Yılmaz, Zeki; Uludağ Üniversitesi/Veteriner Fakültesi/İç Hastalıkları Anabilim Dalı.; 0000-0001-9836-0749; V-5578-2017; 36437200800; 35944810500The objective of this study was to use the Tandem Mass Tag (TMT) isobaric label-based proteomic approach, in order to identify new potential biomarkers for the treatment monitoring of canine leishmaniosis that could not be identified by the use of gel-based techniques. For this purpose serum samples were obtained from 5 clinically diseased dogs before and one month after the treatment of canine leishmaniosis. The non-depleted serum samples were subjected to reduction, alkylation and trypsin digestion, and the resulting peptides were labeled using 6-plex TMT reagents. To obtain information about protein identities and relative quantification, liquid chromatography-MS analysis of multiplexed TMT-labeled peptides was employed. This gel-free, label-based quantitative proteomic approach enabled identification of 117 canine proteins. Among these, 23 showed significant difference (p < 0.05) in expression (two downregulated and 21 upregulated ranging from 1.25 to 2.5 fold change). Comparison of gel-free TMT-based quantification and a gel-based approach previously applied to the same samples resulted in the identification of some common markers (Apo-A1, vitamin D binding protein and RBP4). However, 20 additional differentially represented proteins were highlighted by the gel-free approach, 13 of which have not been previously reported in canine leishmaniosis. In conclusion, the TMT-based proteomic approach allowed identification of new serum proteins that significantly change in concentration after canine leishmaniosis treatment. These proteins are involved in various physiopathological processes such as inflammatory, coagulation or defense mechanisms, and could potentially be suitable biomarkers for treatment monitoring of this parasitic disease.Item Serum butyrylcholinesterase and paraoxonase 1 in a canine model of endotoxemia: Effects of choline administration(Elsevier Science, 2012-10) Tvarijonaviciute, Asta; Tecles, Fernando; Ceron, Jose J.; Kocatürk, Meriç; Cansev, Mehmet; Yılmaz, Zeki; Uludağ Üniversitesi/Veteriner Fakültesi/İç Hastalıkları Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Farmakoloji Anabilim Dalı.; 0000-0001-9836-0749; M-9071-2019; 36437200800; 8872816100; 35944810500Butyrylcholinesterase (BChE) and paraoxonase 1 (PON1) are two serum enzymes synthesized by the liver that are related with inflammation. The main objectives of this study were to determine changes in serum BChE and PON1 by using a canine model of endotoxemia, and to evaluate whether choline alters BChE and PON1 activities during inflammation. For this purpose, a total of 20 mongrel dogs were divided into four groups: control, choline (C), lipopolysaccharide (LPS), and LPS + C. Dogs in the control group were injected with 0.9% NaCl (0.2 ml/kg, i.v.). Dogs in C and LPS + C groups received choline chloride (20 mg/kg, i.v., three times with 4 h intervals). Endotoxin was injected (0.02 mg/kg, i.v., once) to the dogs of LPS and LPS + C groups. Statistically significant decreases in BChE and PON1 activities in LPS group were detected 24 and 48 h post injection, respectively. No statistically significant changes in BChE and PON1 activities at different times were detected in control, C, or LPS + C groups. In conclusion, the data obtained in present study revealed a decrease in serum BChE and PON1 activities in dogs during experimentally induced endotoxemia and that choline administration attenuates these changes.
