Bir yaşlanma modeli olarak Caenorhabditis elegans bireylerinde kalsinörin inhibisyonu ile ortaya çıkan değişiklikler
Öz
Amaç: Kalsinörin inhibisyonunun Caenorhabditis elegans (C. elegans) bireylerinde yaşam süresini
uzattığı bilinmektedir. C. elegans
genlerinin önemli bir kısmı insan genlerine büyük benzerlik göstermektedir. Bu
çalışmada kalsinörin inhibisyonunun C.
elegans bireylerindeki yaşamsal fonksiyonlar üzerine olan etkilerinin
değerlendirilmesi amaçlandı.
Yöntem: Çalışma için bir
kalsinörin inhibitörü olan siklosporin A’nın 1 μM (1.doz), 0.1 μM (2.doz), 0.01
μM (3.doz) ve 0.001 μM (4.doz) dozunda çözeltileri hazırlanarak her bir
çözeltiden 1’er ml, içlerinde 10’ ar ml Nematod Growth Media (NGM) bulunduran
petrilere eklenmiştir. Kontrol grubu siklosporin eklenmemiş besiyerinde
beslenmiştir. Senkronizasyonu yapılmış C.
elegans’lardan siklosporinin belirtilen dozları ile hazırlanmış her bir
petriye 20’ şer adet aktarılmıştır. 6X–50X arasında büyütme sağlayan alttan
ışıklandırmalı stereo mikroskop ile C.
elegans’lar izlenmiştir. Bütün petrilerdeki C. elegans’lar ölene kadar her gün aynı saatte canlı hayvanlar
sayılmış ve kontrol grubuyla karşılaştırılmıştır.
Bulgular: Çalışma
sonucunda siklosporine maruz bırakılan C.
elegans’ların kontrol grubuna göre yaşam sürelerinde doz artışına bağlı
istatistiksel olarak anlamlı bir artış olduğu tespit edilmiştir (p<0,05).
Siklosporine maruz bırakılan C. elegans’ların
fiziksel gelişimlerinin doz artışına bağlı olarak anlamlı derecede azaldığı saptanmıştır
(p<0,05). Siklosporin dozundaki artış farinks pompalama sayısında
istatistiksel olarak anlamlı bir değişikliğe neden olmamıştır (p>0,05).
Sonuç: Kalsinörin
inhibisyonu, C. elegans’ların
gelişimsel sürecini yavaşlatır ve yaşam süresini uzatır. Kalsinörin
inhibitörleri, benzer mekanizmalarla insanlarda deri yaşlanması üzerine olumlu
etki yapabilir. Bu nedenle kalsinörin inhibisyonunun, deri yaşlanması üzerine
etkinliğini ve etki mekanizmasını açıklayacak ileri çalışmalar gereklidir.

Objective: It is known that
calcineurin inhibition prolongs life in individuals with Caenorhabditis elegans (C.
elegans). An important part of C.
elegans genes shows great similarity to human genes. This study aims to
evaluate the effects of a calcineurin inhibitor on vital functions in C. elegans individuals.
Method: In this study,
solutions of cyclosporine A which is a calcineurin inhibitör 1 μM (1.dose), 0.1
μM (2.dose), 0.01 μM (3.dose) and 0.001 μM (4.dose) were prepared and 1 ml from
each solution was taken and added to petri dishes, containing 10 ml Nematode
Growth Media (NGM). The control group was fed the medium which was not added
cyclosporine. The indicated doses of cyclosporine whose synchronization has
been completed were transferred to petri dishes in order that each would have
20 pieces. C. elegans were observed
using bottom light stereo microscop that provided 6X-50X magnification. Live
animals at the same time every day were counted and compared with the control
group until all C. elegans in all
petri dishes died.
Results: The results have
showed that there was a statistically significant increase in life span periods
of C. elegans exposed to cyclosporin
depending on dose increase (p<0,05).
It has been found out that physical development of C. elegans exposed to increased doses of cyclosporin decreased
significantly (p<0,05). The increase in doses of cyclosporin have not caused
statitically significant change in the number of pharynx pumping (p>0,05).
Conclusions: Calcineurin
inhibition slows down the developmental process in C. elegans and prolongs survival, and may produce positive effects
on aging.
