The Claim
The accumulation of glycine during aging in Caenorhabditis elegans is primarily due to reduced expression of genes involved in glycine catabolism, including gldc-1, gcsh-1, and gcst-1, rather than increased synthesis.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
During aging in the worm Caenorhabditis elegans, glycine builds up because genes that break down glycine become less active, not because more glycine is made.
See the scientific wording
The accumulation of glycine during aging in Caenorhabditis elegans is primarily due to reduced expression of genes involved in glycine catabolism, including gldc-1, gcsh-1, and gcst-1, rather than increased synthesis.
As the worm ages, the proteins that break down glycine become less active, so glycine builds up in the body because it is not being used up, even though the worm is not making more of it.
What the research says
1 studyStudy: Glycine promotes longevity in Caenorhabditis elegans in a methionine cycle-dependent fashion
As worms get older, the genes that break down glycine slow down, so glycine builds up — not because they make more of it, but because they can’t break it down as well. The study shows this is exactly what happens.
