Dietary and pharmacological induction of serine synthesis genes

Abstract

There is an increasing interest in the pathway of L-serine synthesis and its. Although L-serine and downstream products can be obtained from the diet, serine deficiency has been documented in neurological disorders, macular degeneration and aging. This evidence calls for strategies to induce serine synthesis. Here I address this problem taking advantage of the wealth of data deposited in the gene expression omnibus database. I uncover that low protein and ketogenic diets increase the expression of serine synthesis genes in the liver and the brain relative to control diets. I discover oestrogen medications, the antifolate methotrexate and serine synthesis inhibitors as classes of compounds inducing the expression of serine synthesis genes in the liver. Future work is required to investigate the use of these interventions for the management of serine deficiency disorders.Competing Interest StatementThe authors have declared no competing interest.View Full Text
