The three principal objectives of this commentary are to: (i) review the existing evidence, which suggests regulation, by glucose and other insulin secretagogues, of PP2A in the beta cell; (ii) discuss the experimental evidence, which implicates PP2A-like enzymes in the dephosphorylation and inactivation of key beta cell phosphoprotein substrates (e.g., Akt and Bcl-2), which may be necessary for beta cell proliferation and survival, culminating in the loss of the beta cell mass; and (iii) highlight potential avenues for future research, including the development of specific pharmacological and therapeutic interventional modalities for the inhibition of specific PP2A-like phosphatases for the prevention of loss of beta cell mass leading to the onset of diabetes.

64 |
16951721
|
These findings suggest that stimulation of insulin production and prevention of beta cell loss by American ginseng extracts can occur via the inhibition of mitochondrial UCP-2, resulting in increase in the ATP level and the anti-apoptotic factor Bcl-2, while down-regulation of pro-apoptotic factor caspase-9 occurs, lowering the occurrence of apoptosis, which support the hypothesis.
