solid plate-based dietary restriction in caenorhabditis elegans

Yetersiz beslenme veya açlık olmadan gıda alımının azaltılması, ömrünü uzatır ve memeliler dahil olmak üzere çeşitli türlerin geniş bir yelpazede, yaşa bağlı hastalıkları, başlangıcından gecikme bilinir. Aynı zamanda vücut ağırlığı ve doğurganlık azalması yanı sıra, plazma glukozu, insülin ve IGF-1, bu hayvanlarda düşük seviyelerde neden olur. Bu tedavi genellikle diyet kısıtlaması (DR) ya da kalori kısıtlaması (CR) olarak adlandırılır. Nematod Caenorhabditis elegans yaşlanma biyoloji eğitimi için önemli bir model organizma olarak ortaya çıkmıştır. Her ikisi de çevresel ve genetik manipülasyonlar modeli DR kullanılmış olan ve C. ömrünü uzatmaya göstermiştir elegans. Ancak, C. içinde bildirilen DR çalışmaları birçok elegans yaşlanma alanında genetik çalışmaların çoğu standart katı agar petri tabak yapıldı, sıvı ortamda hayvanların propaganda yapıldı. Burada öldürülmüş bakteri içeren standart katı NGM agar tabanlı plaka kullanarak DR protokol sunuyoruz.
