Main Results:

  • Dietary nucleotide deficiency negatively affects protein synthesis in rat liver and small intestine.
  • Ribosome degradation is a key mechanism contributing to impaired protein synthesis.
  • Dietary nucleotides modulate gene expression via transcription factor interactions.

Conclusions:

  • Dietary nucleotides are crucial for maintaining protein synthesis and tissue homeostasis.
  • Nucleotide deficiency can lead to significant cellular dysfunction, including ribosome degradation.
  • Nucleotides play a regulatory role in gene expression in the liver and small intestine.
