The proactive arm governs proteome production and maturation, translation, co-translational quality control, chaperone-assisted folding, trafficking, and compartment-specific targeting, thereby limiting the generation of metastable or mislocalized proteins (Fig
The advantages include faster delivery and higher bioavailability, making it ideal for those with digestive issues or for individuals requiring targeted dosing
First, optimal dosing in humans remains undefined, with current practice based primarily on extrapolation from animal studies and anecdotal clinical experience rather than formal dose-finding studies
7 In fact, xCT is considered to be the main transporter of cystine in cancer (Table 1) 25,26,27 and its expression is controlled by nuclear factor erythroid 2-related factor 2 (NRF2), a master regulator of the cellular redox state, 28 highlighting the importance of xCT in an oxidative stress-resistant cancer cell phenotype
