General description

A cell-permeable and reversible stearated 13-amino acid peptide corresponding to the N-terminus of MEK1 (MAPKK) that acts as a specific inhibitor of ERK activation and blocks the transcriptional activity of Elk1. Selectively binds to ERK2 and prevents its interaction with MEK (IC50 = 2.5 µM). Potently blocks ERK activation in PMA-stimulated NIH 3T3 cells and NGF-treated PC12 cells (IC50 = 13 µM). Does not affect the activation of JNKs or p38.
A cell-permeable, reversible, and stearated, 13-amino acid peptide corresponding to the N-terminus of MAPK/ERK kinase (MEK). Acts as a specific inhibitor of ERK activation and blocks the transcriptional activity of ELK1. Selectively binds to ERK2 and prevents its interaction with MEK (IC50 = 2.5 µM). Shown to block ERK activity in PMA-stimulated NIH3T3 cells and NGF-treated PC12 cells (IC50 = 13 µM). Does not affect the activation of either JNKs or p38 MAP kinase.

Pancreatic ductal adenocarcinoma (PDAC) frequently metastasizes into the peritoneum, which contributes to poor prognosis. Metastatic spreading is promoted by cancer cell plasticity, yet its regulation by the microenvironment is incompletely understood. Here, we show that the presence of hyaluronan and
