Results showed that EEAP and quercetin but not ferulic acid protected beta - cells from glucotoxicity through several mechanisms , including : ( 1 ) maintaining beta - cell viability ; ( 2 ) suppressing reactive oxygen species production ; ( 3 ) reducing characteristic features of apoptosis ; ( 4 ) inhibiting the activation of caspase - 9 and caspase - 3 and the cleavage of poly ( ADP - ribose ) polymerase ; ( 5 ) upregulating pancreatic and duodenal homeobox 1 gene expression and the insulin secretagogue action of pancreatic beta - cells .
