The C-terminal domain BIRD of Bas1 is sensitive to a high concentration of the direct riboflavin precursor GTP, where it binds to sites of ADE4 and serine hydroxymethyltransferase (SHM2) promoters to depress the de novo purine pathway
While direct evidence linking the RARA::RXRA and RARA::RXRG complexes to CCL11 expression in the CNS is currently not well established, it is plausible to speculate that retinoic acid signaling through these complexes could inhibit CCL11 expression in specific brain conditions
Identifying similarities between metabolite alterations in GWS and ME/CFS is an important step toward uncovering potential therapeutic targets and enhancing our understanding of the underlying pathophysiology that contributes to shared symptoms, such as fatigue
[5] A summary of implicated proteins and organ involvement is provided in Table 1
The most commonly mentioned effects include mild nausea in some users (typically transient), injection site reactions (redness, minor discomfort), mild headache or dizziness (uncommon), and sleep disruption with late-day dosing (reported by some users)
