D- as well as L-methionine were found to be equally effective, suggesting that depletion of sulfur was at the root of the primary defect and that it was unrelated to protein synthesis
To adapt to this environmental condition, cells depend on their redox system operating in reactive (feedback) and predictive (feedforward) modes, ultimately establishing new gene expression patterns which present as increased expression of antioxidant enzymes and stress defense proteins
Cell cycle stage was determined by flow cytometry using the BD LSR II Flow Cytometer (Becton Dickinson)
Mechanistically, GLP-1 receptor agonists may exert vascular protective effects by suppressing inflammation, limiting oxidative stress, and modulating key enzymes involved in extracellular matrix remodeling ( Matrix metalloproteinases, particularly MMP-9, together with their endogenous inhibitors (TIMPs), play central roles in extracellular matrix turnover and structural vascular remodeling ( The reduction in CRP, a recognized marker of aortic stiffness, medial degeneration, and systemic inflammation, further supports the anti-inflammatory profile associated with GLP-1RA therapy

These symptoms often improve over time and with dose stabilisation, though patterns vary between individuals
