Time-Resolved Limited Proteolysis of Mitogen-Activated Protein Kinase-Activated Protein Kinase-2 Determined by LC/MS Only

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...

Redox-dependent dimerization of p38α mitogen-activated protein kinase with mitogen-activated protein kinase kinase 3

The kinase p38α MAPK (p38α) plays a pivotal role in many biological processes. p38α is activated by canonical upstream kinases that phosphorylate the activation region. The purpose of our study was to determine whether such activation may depend on redox-sensing cysteines within p38α. p38α was activated and formed a disulfide-bound heterodimer with MAP2K3 (MKK3) in rat cardiomyocytes and isolat...

Increased Mitogen-Activated Protein Kinase

Mitogen-Activated Protein Kinase Activation

DBM1285 suppresses tumor necrosis factor alpha production by blocking p38 mitogen-activated protein kinase/mitogen-activated protein kinase-activated protein kinase 2 signaling pathway.

Tumor necrosis factor alpha (TNF-alpha) is a major inflammatory cytokine that plays an important role in the development of various inflammatory diseases. TNF-alpha has been considered as a potential therapeutic target for the treatment of chronic inflammatory diseases, including rheumatoid arthritis and inflammatory bowel disease. In this study, we report that cyclopropyl-{4-[4-(4-fluorophenyl...
