Both receptors couple to Gs proteins and activate adenylyl cyclase, raising intracellular cAMP in beta cells and triggering insulin exocytosis in a glucose-dependent manner
The presence of an increase in protein levels at the expected molecular weight on an SDS-PAGE gel after induction with IPTG is a good indication of successful protein expression
No specific products are officially endorsed for use with these treatments, and individual needs vary considerably
A recent study suggests that Bcl-2 regulates mitochondrial GSH content by a direct interaction of the BH3 groove with GSH [132], while the antiapoptotic effect of Bcl-xl has also been attributed to the regulation of GSH homeostasis by preventing GSH loss [133] Figure 5

While this might partly subcellular compartmentation and the lower reducing power (higher redox potential) of ascorbate compared to glutathione, NADH, and NADPH, it also points to efficient co-operation between the various isoforms of the three reductases
