PFOS ile tedavi edilen Sertoli hücre kültüründe ezrin ve fascin 1'in araştırılması: İn vitro bir çalışma

Amaç: Bu çalışmada, Ezrin ve Fascin 1’in in vivo olarak baskılanması sonucundaki bulgularla birlikte, Kan testis bariyeri (KTB) yapısının bozulması ve primer Sertoli hücre kültüründe, Perflorooktansülfonat (PFOS) muamelesinden sonra F-aktin demetlenmesinin gösterilmesi amaçlanmaktadır.Yöntem: Çalışma Tasarımı: Primer Sertoli hücre izolasyonu, kontrol ve PFOS ile muamele edilen (20μM) gruplarla yapıldı. Sertoli hücre konsantrasyonu her iki deney için 0.5 x 106 hücre/ml olacak şekilde hazırlandı. Metod: Hem Fascin 1'in Sertoli hücrelerinde Ezrin ile birlikte lokalizasyonunu değerlendirmek üzere çift etiketli immünofloresan analizi yapıldı, hem de seminifer tübül lizatlarından aktin ve Ezrin proteinlerinin Fascin 1 proteini ile spesifik protein-protein etkileşimini tanımlamak için Co-IP deneyi uygulandı.Bulgular: İlk olarak, ektoplazma özelleşmesi bileşenleri olan Ezrin ve Fascin 1 in Sertoli hücrelerinde ko-lokalize olduğu ve birbirleri ile etkileşime girdiği gösterilmiştir. İkinci olarak ise PFOS ile muamele edilen Sertoli hücrelerinde Ezrin ve Fascin 1 dislokasyonu gösterilmiştir. 20μM PFOS uygulandığında aktin tabanlı hücre iskeleti KTB’deki hüce-hücre bağlantı bölgelerindeki aktin düzenleyici proteinlerin yayılmasını ve/veya lokalizasyonunu destekleyememiştir.Tartışma: Sonuç olarak bu bulgular, PFOS aracılı Sertoli hücre bozulmasında, Ezrin ve Fascin 1'in KTB bütünlüğünü korumak için F-aktin organizasyonunu düzenleyerek birlikte çalışabileceğini desteklemektedir.

Evaluation of ezrin and fascin 1 in the PFOS treated Sertoli cell culture: An in vitro study

Aim: Depending on the findings resulting from the knock-downing of ezrin and of fascin 1 in vivo, we aim to show the defects or disruption of the blood-testis barrier (BTB) structure and F-actin bundling after Perfluorooctanesulfonate (PFOS) treatment in primary Sertoli cell culture.
