Induced Ca2+ uptake and callose synthesis in suspension-cultured cells of Catharanthus roseus are decreased by the protein phosphatase inhibitor okadaic acid

Activation of p38 mitogen-activated prot

Activation of p38 mitogen-activated protein kinase and mitochondrial Ca2+-mediated oxidative stress are essential for the enhanced expression of grp78 induced by the protein phosphatase inhibitors okadaic acid and calyculin A

We have reported that treatment with okadaic acid, a potent protein phosphatase inhibitor, has the ability to enhance the synthesis of the 78-kDa glucose-regulated protein (GRP78). This article reports our investigation of another protein phosphatase inhibitor, calyculin A, demonstrating the signali
