Abstract

Rapamycin which is an inhibitor of mammalian target of rapamycin (mTOR), has effects as antineoplastic, retarding aging, anti-inflammatory and neuroprotective. Aim of this study is to investigate the effects of rapamycin on maternal aggression in rats. In this study 63 Wistar female rats were used. The animals were divided into 3 groups: the solvent (DMSO) group, the 5 mg/kg rapamycin group, and the 10 mg/kg rapamycin group. For behavioral testing the resident-intruder paradigm was used. The groups were compared in terms of the latency to the first aggressive behavior, the number of attacks, the total duration of aggressive behaviors and the intensity of attacks. When the groups were compared in terms of the latency to the first aggressive behavior, it was found that 5 and 10 mg/kg rapamycin groups were significantly prolonged latencies compared to the control group. When were evaluated the number of aggressive behaviors, total duration of aggressive behaviors and average severity of attacks it was found that 5 mg/kg rapamycin group's values were significantly lower than the control groups. These results show that acute administration of rapamycin, especially in 5 mg/kg dose of rapamycin prolongs the latency of maternal aggression, and decreased the number of attacks, the intensity of attacks and the total duration of aggressive behaviors in rats. Therefore rapamycin may have potential for use as a sedative drug, however it is necessary to conduct further studies.

Özet

Memelideki rapamisin hedefinin (mTOR) bir inhibitörü olan rapamisin antineoplastik, yaşlanmayı geciktirici, anti-inflammatuar ve nöroprotektif etkilere sahiptir. Bu çalışmadaki amacımız sıçanlarda rapamisinin maternal agresyon üzerine etkisini araştırmaktır. Çalışmada 63 adet dişi Wistar sıçan kullanıldı. Hayvanlar çözücü (DMSO) grubu, 5 mg/kg rapamisin grubu ve 10 mg/kg rapamisin grubuna ayrıldı. Davranış testi için ev sahibi-yabancı paradigması kullanıldı. Gruplar; ilk agresif davranışın başlama zamanı, toplam atak sayısı, agresif davranışın toplam süresi ve atak şiddeti açısından karşılaştırıldı. Gruplar ilk agresif davranış başlama zamanı bakımından karşılaştırıldığında 5 ve 10 mg/kg rapamisin gruplarının kontrol grubuna göre başlama zamanını anlamlı düzeyde uzattığı bulundu. Toplam agresif davranış sayısı, agresif davranışın toplam süresi ve ortalama atak şiddeti değerlendirildiğinde 5 mg/kg rapamisin grubunun değerleri kontrol grubuna göre anlamlı düzeyde düşük bulundu. Bu sonuçlar akut rapamisin uygulamasının, özellikle 5 mg/kg dozda, sıçanlarda maternal agresyonun başlama zamanını uzattığını, toplam atak sayısı, atak şiddeti ve agresyonda geçen toplam süreyi kısalttığını göstermektedir. Fakat rapamisinin sedatif bir ilaç olarak kullanılabilme potansiyeline sahip olabilmesi için daha ileri çalışmalar gerekmektedir.
