Effects of coadministration of DHA and vitamin E on spermatogram, seminal oxidative stress, and sperm phospholipids in asthenozoospermic men: a randomized controlled trial
[115] described that phosphoglycerate dehydrogenase (PHGDH), involved in the synthesis of serine and glycine from glucose, is critical for pancreatic tumor cells proliferation and tumorigenesis, mediating cell-tight junctions formation, mTOR activation (through Akt), and protein expression and translation, after interaction with the translation initiation factors eIF4A1 and eIF4E (which seems to be independent of its enzymatic activity)
Meta-analyses indicate that these nutrients can be beneficial, but further large-scale, well-designed trials are needed
