Abstract



Bu çalışmanın amacı, Van Gölü’nden yakalanan dişi Alburnus tarichi’de P450 aromataz izoformları olan beyin kaynaklı Cyp19b ve ovaryum kaynaklı Cyp19a genlerini klonlanmak ve üreme bakımından ovaryum gelişimi engellenmiş (RA) ve ovaryum gelişimi normal olan (RN) balıklardan alınan hypothalamus ve ovaryum örneklerinde bu genlerin ekspresyon seviyelerini belirlemektir. Cyp19b gen ekspersyonu beyinde, Cyp19a gen ekspresyonu ise ovaryumda daha fazlaydı. Cyp19b mRNA seviyesi, RA balıkların ovaryum ve hipotalamusunda, RN balıkların ovaryum ve hipotalamusundan belirgin olarak düşüktü (P<0.05). CYP19a ekspresyon seviyesi, hem RN ve hem de RA balıkların hipotalamusunda fark bulunmazken RA balıkların ovaryumunda, RN balıkların ovaryumundan belirgin olarak düşüktü (P<0.05). Bu sonuçlara bize, RA balıkların populasyonun bir parçası olduğunu ve bu balıkların endokrin bozucu bileşik veya bileşiklere diğer balıklardan daha çok duyarlı olabileceğini düşündürmektedir.

Abstract



In this study, we aimed to clone brain-derived Cyp19b and ovary-derived Cyp19a the P450 aromatase gene isoforms and to indicate the expression levels of these genes in the hypothalamus and ovary tissues from reproductively arrested ovarian development (RA) and non-arrested ovarian development (RN) Alburnus tarichi from Lake Van, Turkey. The expression levels of Cyp19b and Cyp19a genes were predominant in the hypothalamus and ovary, respectively. The level of Cyp19b mRNA was significantly lower in the hypothalamus and ovary from RA fish than in the hypothalamus and ovary from RN fish (P<0.05). The expression level of Cyp19a was significantly lower in the ovary of RA fish (P<0.05) than RN fish while no difference was found in the hypothalamus of both RA and RN fish (P<0.05). According to these findings, we suggest that the RA fish represent a segment of the population and these fish may be more sensitive to endocrine disruption compound/s than others.
