Numerous events in the cell, such as gene expression, cell growth and metabolism are regulated by signal transduction pathways involving protein kinase C (PKC). Recent data indicate that a PKC-dependent mechanism also underlies the apoptotic death of cells induced by glucocorticoid hormones. In this report we have analysed the changes of PKC during dexamethasone-induced apoptosis in thymocytes by means of immunocytochemical and immunochemical analysis. The data obtained show an increase and intracellular movement of protein kinase C, which is translocated to the nucleus and linked to the nuclear matrix during the apoptotic process.

Abstract
Numerous events in the cell, such as gene expression, cell growth and metabolism are regulated by signal transduction pathways involving protein kinase C (PKC). Recent data indicate that a PKC-dependent mechanism also underlies the apoptotic death of cells induced by glucocorticoid hormones. In this report we have analysed the changes of PKC during dexamethasone-induced apoptosis in thymocytes by means of immunocytochemical and immunochemical analysis. The data obtained show an increase and intracellular movement of protein kinase C, which is translocated to the nucleus and linked to the nuclear matrix during the apoptotic process.File in questo prodotto:
