Updated project metadata. Supplementation with S-adenosylhomocysteine (SAH) extends the lifespan of model organisms. To explore the impact of SAH on aging, we generated a Caenorhabditis elegans model with increased SAH levels through pathogenic mutation in the S-adenosylhomocysteine hydrolase (AHCY-1), which impairs SAH hydrolysis to adenosine and homocysteine. This submission contains results of the quantitative (TMT) measurements of the proteins in whole worm extracts originated from AHCY-1 Y143C mutant (equivalent to the human pathogenic variant) and control worms.
