Project description:RNA-seq analysis of adult wildtype C.elegans worms which were exposed to two concentrations of H2S (50 and 150ppm) or oxygen control (7% O2), over time (1,2,12h). A likely mixup of some samples was noted based on clustering analysis, and metadata here has been corrected. The original filename contains the initial annotation.
Project description:Hydrogen sulfide (H2S) is formed naturally from L-cysteine in a variety of mammalian and non-mammalian cells. To date, numerous biological effects have been ascribed to H2S including control of cardiovascular, immune and nervous function. Over or under production of H2S has been observed in several disease states including hypertension and inflammation. In addition, it has been stipulated that H2S may affect the ageing process. The model nematode Caenorhabditis elegans is ideally suited for assessing drug effects on lifespan since it is relatively short-lived, can be easily exposed to drugs and its genome is fully sequenced and widely annotated.

The model nematode Caenorhabditis elegans is ideally suited for assessing drug effects on lifespan since it is relatively short-lived, can be easily exposed to drugs and its genome is fully sequenced and widely annotated. The global transcriptome of control nematodes (raised using standardized laboratory conditions) was compared to nematodes exposed to 100 uM GYY4137 (morpholin-4-ium 4 methoxyphenyl(morpholino) phosphinodithioate), a slow releasing H2S donor drug.
