Genetic Structure and Variation of Van Cats
(Springer/plenum Publishers, 2011) Altunok, Vahdettin; Yuksek, Nazmi; Berkman, Ceren C.; Agaoglu, Zahid Tevfik; Togan, Inci
To determine the genetic structure and variation of Van cats and some other cats, seven enzyme loci were examined using horizontal starch gel electrophoresis. ME bands were observed for the first time in cats. For the enzyme loci CA (1) , SOD, GPI, and GOT, neither the individual Van cats nor the specimens of other cat species exhibited any variation. These enzymes presented identical bands, all of which were homozygous. With respect to the PGD, ME, and ESD loci, however, genetic variation was observed in all of the cats. Hence, three of the seven gene-enzyme systems (43%) were polymorphic with two alleles, contributing to an estimate of average heterozygosity of 0.33-0.49 for the Van cats. PGD was the most discriminatory among the three polymorphic loci. The phylogenetic tree indicated that the Van, Persian, Turkish Angora, and Turkish Tekir cats are distinct from Siamese and Bombay cats.
Immunoglobulins and Acute Phase Proteins in Van Cats - Associations With Sex, Age, and Eye Colour
(Tubitak Scientific & Technological Research Council Turkey, 2021) Coskun, Pinar; Altunok, Vahdettin; Kazak, Filiz; Yuksek, Nazmi
It was aimed to determine concentrations of plasma immunoglobulins (IgG, IgA, IgM) and acute phase proteins (alpha-1 acid glycoprotein, serum amyloid A, ceruloplasmin) and the association of these parameters with age, sex, and eye colour in Van cats. Blood plasma of healthy, forty-seven Van cats (Van Cat Home) fed with standard cat food were involved in the study. Cats were divided into four groups based on age (<1, 2 to 2.5, 3 to 4, > 5) and eye colour (amber-amber, amber-blue, blue-amber, and blue-blue eyes described from left to right), and two groups based on sex (male and female). Plasma IgG, IgA, IgM, alpha-1 acid glycoprotein, serum amyloid A, and ceruloplasmin concentrations were determined, and the concentrations were found to be 2.20 +/- 0.05 mg/mL, 1.05 +/- 0.04 mg/mL, 2.52 +/- 0.18 mg/mL, 562.00 +/- 14.27 mu g/mL, 1.49 +/- 0.03 mu g/mL, and 2.88 +/- 0.13 mg/dL, respectively. Male Van cats had higher IgA levels than the female cats (P < 0.05). alpha-1 acid glycoprotein concentrations in cats under 1-year-old were higher from that in the other age groups, whereas the significant difference was obtained compared to 2 to 2.5-year-old cats (p < 0.05). IgM concentrations were higher in cats with blue-blue eye colour than in the cats with other eye colours, while statistically significant difference was observed only cats with amber-blue eye colour (p < 0.05). Amber-amber eyed cat plasma ceruloplasmin concentrations were higher from that in the other eye coloured cats while significant difference was determined compared to amber-blue eyed cats (p < 0.05). Plasma immunoglobulins and acute phase proteins were determined and the associations of these parameters with age, sex, and eye colour were examined for the first time in Van cats. These data are thought to be important as reference levels in terms of diagnosis and prognosis.
Relation of Some Biochemical Parameters in Van (Turkey) Cats With Sex, Age, Eye Colour and Hair Length
(2018) Akalın, Pınar Peker; Başpınar, Nuri; Altunok, Vahdettin; Yuksek, Nazmi
Amaç: Van kedileri, doğu Türkiye kaynaklıdır ve ulusal kültürel varlıkların bir parçasıdır. Van kedilerinin en belirgin özelliği, gözlerinin renkleridir (diskromatopsi). Bu çalışmanın amacı, Van kedilerinde plazma aspartat aminotransferaz, alanin aminotransferaz aktiviteleri, total protein, albümin, glikoz, trigliserit, LDL kolesterol, HDL kolestrol, kan üre / nitrojen ve kreatinin düzeylerini saptamak ve bu parametrelerin cinsiyet, yaş, göz rengi ve tüy uzunluğu ile ilişkisini araştırmaktır. Gereç ve Yöntem: Bu çalışmada, standart kedi yemi ile beslenen, sağlıklı, 47 adet Van kedisi (Van Kedi Evi, Yuzuncu Yil Üniversitesi, Van) kan plazması kullanıldı. Kediler, cinsiyet (dişierkek), yaş (1-2; 3-4; 5'in üzerinde), göz rengi (amber-amber, amber-mavi, mavi-amber, mavi-mavi, soldan sağa açıklanan gözler) ve tüy uzunluğu (kısa; uzun) temel alınarak gruplara ayrıldı. Plazma biyokimyasal parametreleri ticari kitlerle kolorimetrik olarak spektrofotometre ile belirlendi.Bulgular: Cinsiyete ilişkin olarak parametreler arasında fark yoktu. Kısa tüylü kedilerde uzun tüylü kedilere göre albumin düzeyleri daha yüksekti (p<0.05). Göz rengi açısından değerlendirildiğinde, mavi-mavi gözlü kedi plazma glikoz düzeyleri diğer göz rengi gruplarına göre çok daha yüksekti (p<0.001). Yaş gruplarında, 1-2 yaşındaki kedilerde kreatinin düzeyleri diğer yaş gruplarına göre daha düşüktü (p<0.05)Öneri: Sonuçlarımız, Van kedilerinin plazma biyokimyasal parametrelerininbazılarının göz rengi, yaş ve tüy uzunluğu ileilişkili olabileceğini göstermiştir. Ayrıca Van kedilerinden eldeedilen bu biyokimyasal bulguların, klinik tanıda yarar sağlayacağıdüşünülmektedir.
