1 PURPOSE: To study the signal transduction mechanisms of tamoxifen via the activation of MAPKs, JNK and ERK in order to understand its regulation of gene expression. Tamoxifen mitogen-activated protein kinase 8 Homo sapiens
2 RESULTS: TAM activated both JNK1 and ERK2 activities in a time- and dose-dependent manner in HeLa cells. Tamoxifen mitogen-activated protein kinase 8 Homo sapiens
3 The activation of JNK1 was enhanced when the cells were pretreated with prooxidant H2O2. Hydrogen Peroxide mitogen-activated protein kinase 8 Homo sapiens
4 CONCLUSIONS: These studies show that TAM activates the signal transduction kinases, JNK1 and ERK2, which may play important roles in the regulation of gene expression by TAM. Tamoxifen mitogen-activated protein kinase 8 Homo sapiens
5 CONCLUSIONS: These studies show that TAM activates the signal transduction kinases, JNK1 and ERK2, which may play important roles in the regulation of gene expression by TAM. Tamoxifen mitogen-activated protein kinase 8 Homo sapiens
