interestingly, whereas in c3h islets, high glucose levels led again to significant elevation of txnip and apoptosis levels as measured by tunel (terminal deoxynucleotidyl transferase-mediated dutp nick-end labelling) and cleaved caspase 3, no increase in apoptosis was observed in txnip-deficient hcb-19 islets, indicating that txnip is required for beta-cell death caused by glucotoxicity. |
