1 Protective effect of paraoxonase-2 against endoplasmic reticulum stress-induced apoptosis is lost upon disturbance of calcium homoeostasis. Calcium paraoxonase 2 Homo sapiens
2 Addressing the cytoprotective functions of PON2, we observed that PON2 overexpression provided significant resistance to ER-stress-induced caspase 3 activation when the ER stress was induced by interference with protein modification (by tunicamycin or dithiothreitol), but not when ER stress was induced by disturbance of Ca(2+) homoeostasis (by thapsigargin or A23187). Tunicamycin paraoxonase 2 Homo sapiens
3 Addressing the cytoprotective functions of PON2, we observed that PON2 overexpression provided significant resistance to ER-stress-induced caspase 3 activation when the ER stress was induced by interference with protein modification (by tunicamycin or dithiothreitol), but not when ER stress was induced by disturbance of Ca(2+) homoeostasis (by thapsigargin or A23187). Dithiothreitol paraoxonase 2 Homo sapiens

Calcimycin paraoxonase 2 Homo sapiens
6 However, only tunicamycin and dithiothreitol resulted in increased PON2 mRNA and protein levels. Tunicamycin paraoxonase 2 Homo sapiens
7 However, only tunicamycin and dithiothreitol resulted in increased PON2 mRNA and protein levels. Dithiothreitol paraoxonase 2 Homo sapiens
8 In addition, thapsigargin and A23187 also induced PON2 protein degradation by a Ca(2+)-dependent calpain-mediated mechanism. Thapsigargin paraoxonase 2 Homo sapiens
