In addition, glutamine, but not glutamate, is an important specific precursor for the synthesis of mucins, which are critical for the defense against infections and are suggested to protect against allergic sensitization (100103)
Sepiapterin is a stable precursor in the salvage pathway of BH 4 biosynthesis, which converts sepiapterin to BH 4 via the activities of sepiapterin reductase and DHFR (Figure 8)
8.1.3 Network biology approach While pathway analysis highlights the dysregulated processes, network-based approaches extend this by mapping the interaction between genes, proteins, and molecular regulators within complex cellular systems, offering a complete holistic view of system-level changes (287, 288)
