Dieetbeperking (DR) is bekend dat de levensduur te verhogen en het begin van verschillende leeftijd gerelateerde ziekten vertraging in een breed scala aan soorten, waaronder zoogdieren 5-7. Zowel de milieu-en genetische manipulaties zijn gebruikt om het model DR in C. elegans, waaronder het kweken van wormen in een semi-gedefinieerde vloeibaar medium 8,9, verdunning van de bacteriële voedselbron in vloeibaar medium 10-12, en het gebruik van het gedrag van mutanten die zich voed...

solid plate-based dietary restriction in caenorhabditis elegans

Vermindering van de voedselinname, zonder ondervoeding of honger is bekend dat de levensduur te verhogen en het begin van verschillende leeftijd gerelateerde ziekten in een breed scala aan soorten, waaronder zoogdieren vertraging. Het veroorzaakt ook een afname in lichaamsgewicht en de vruchtbaarheid, maar ook lagere niveaus van plasma glucose, insuline en IGF-1 in deze dieren. Deze behandeling wordt vaak aangeduid als calorische restrictie (DR) of calorische restrictie (CR). De nematode Caenorhabditis elegans heeft zich ontpopt als een belangrijk modelorganisme voor het bestuderen van de biologie van veroudering. Zowel de milieu-en genetische manipulaties zijn gebruikt om het model DR en hebben aangetoond dat de levensduur te verlengen in C. elegans. Echter, veel van de gerapporteerde DR studies in C. elegans werden gedaan door het propageren van dieren in vloeibare media, terwijl de meeste van de genetische studies in de verouderende gebied werden gedaan op de standaard solide agar in petri-platen. Hier presenteren wij een DR-protocol met behulp van standaard solid NGM agar-based bord met gedode bacteriën.
