In this context, several sensors and pathways regulating the transcription factors, such as activator protein 1 (AP-1), cAMP response element-binding protein (CREB), hypoxia inducible factor-1 (HIF-1), nuclear factor B (NF-B), activating transcription factor 4 (ATF-4), and nuclear factor-erythroid 2-related factor-2 (Nrf2), have been described (Marinho et al
This precise administration maximizes the therapeutic benefits and minimizes the risk of complications
In rats, GCLC has a Km for glutamate that is about 10-fold higher than that of the GCL holoenzyme, which is higher than the cellular glutamate concentration in most tissues GCL is specific for the glutamyl moiety and is regulated physiologically by: (a) non-allosteric feedback competitive inhibition by glutathione (GSH) (Ki = 2.3 mM) which involves binding of GSH to the glutamate and another site on the enzyme [8, 9] and (b) availability of its precursor, cysteine [1]
