Effect of D-serine on gene expression in Neuro2a cells

GSE268106 Mus musculus Expression profiling by high throughput sequencing 6 samples Submitted 2024/12/01 Platform GPL24247
Summary
Serine metabolism provides essential metabolites for cellular growth and proliferation, and also produces neurotransmitters. However, how serine metabolism coordinates with functional development of neurons remains unclear. We report neurotransmitter D-serine inhibit growth of immature cells. Metabolomic analysis of neural progenitors revealed that D-serine decreases glycine synthesis thereby diminishes one-carbon metabolism, in which L-serine is a crucial carbon donor. D-serine inhibits one-carbon metabolism by competing transport of cytosolic L-serine to mitochondria, which restrains proliferation and triggers apoptosis of neural progenitors as well as neural tumor cells, but not mature neurons, in vitro and ex vivo. This RNA-seq data supports the idea that D-serine inhibits polarization and growth/proliferation of immature neurons and further indicate that immature neurons counteracts D-serine-induced cellular stress through enhancing mitochondrial function, including energy synthesis.
