However, the aromatase-A mRNA level was significantly increased with 0.1 µg/L of phthalate, while no changes were observed with 1 and 10 µg/L of phthalate.Conclusion: These results suggest that short-time expose to environmentally relative concentrations of phthalate do not significantly affect genes in steroid synthesis during the early larval development of Alburnus tarichi.

Özet

Amaç: Bu çalışmanın amacı Alburnus tarichi’nin erken larval gelişimi üzerine fitalatın etkisini belirlemektir.Yöntem: Erken larval dönemde (yumurtadan çıktıktan 2 gün sonra) 0.1, 1, ve 10 µg/L fitalat’a, 6 gün, maruz bırakılarak larvalarda östrojen reseptörleri alfa, beta-1 ve beta-2 ve aromataz B ve A’nın mRNA seviyeleri ölçüldü. Bulgular: Fitalat’ın her üç konsantrasyonunda östrojen reseptör alfa, beta1, beta2 ve aromataz B’nin mRNA seviyelerinde belirgin bir değişiklik olmadığı belirlendi. Bununla birlikte aromataz A mRNA seviyesi fitalat’ın 0.1 µg/L uygulamasında belirgin olarak artarken 1 ve 10 µg/L uygulamalarda değişiklik gözlenmedi.Sonuç: Bu sonuçlar, fitalat’ın çevresel konsantrasyonlarının kısa sureli uygulamalarda, Alburnus tarichi erken larval gelişimi sırasında, steroid sentezindeki genleri önemli seviyede etkilemediğini göstermiştir. Bununla birlikte fitalat’ın gen ekspresyonu üzerindeki etkisini belirlemek için, dış beslenmeyi de içine alan uzun süreli uygulamalı çalışmalara ihtiyaç vardır.
