Inactivation of mitogen-activated protein kinase signaling pathway reduces caspase-14 expression in impaired keratinocytes
Objective(s):Several investigations have revealed that caspase-14 is responsible for the epidermal differentiation and cornification, as well as the regulation of moisturizing effect. However, the precise regulation mechanism is still not clear. This study was aimed to investigate the expression of caspase-14 in filaggrin-deficient normal human epidermal keratinocytes (NHEKs) and to explore the...
متن کاملInorganic lead activates the mitogen-activated protein kinase kinase-mitogen-activated protein kinase-p90(RSK) signaling pathway in human astrocytoma cells via a protein kinase C-dependent mechanism.
We have previously reported that lead acetate activates protein kinase Calpha (PKCalpha) and induces DNA synthesis in human 1321N1 astrocytoma cells. In this study, we investigated the ability of lead to activate the mitogen-activated protein kinase (MAPK) cascade. We found that exposure to lead acetate (1-50 microM) resulted in concentration- and time-dependent activation of MAPK (extracellula...
متن کاملPlant mitogen-activated protein kinase signaling cascades.
Mitogen-activated protein kinase (MAPK) cascades have emerged as a universal signal transduction mechanism that connects diverse receptors/sensors to cellular and nuclear responses in eukaryotes. Recent studies in plants indicate that MAPK cascades are vital to fundamental physiological functions involved in hormonal responses, cell cycle regulation, abiotic stress signaling, and defense mechan...

متن کاملRas/mitogen-activated protein kinase signaling activates Ets-1 and Ets-2 by CBP/p300 recruitment.
Cell signaling affects gene expression by regulating the activity of transcription factors. Here, we report that mitogen-activated protein kinase (MAPK) phosphorylation of Ets-1 and Ets-2, at a conserved site N terminal to their Pointed (PNT) domains, resulted in enhanced transactivation by preferential recruitment of the coactivators CREB binding protein (CBP) and p300. We discovered this phos...
