Application

FR180204 has been used as ERK inhibitor:
  • to block extracellular-signal-regulated kinase (ERK) in order to validate whether homeobox B7 (HOXB7) regulates the migration and proliferation process via AKT/mitogen-activated protein kinases (MAPK) signaling
  • of extracellular-signal-regulated kinase (ERK) to study the effects of signaling pathway inhibitors on differentiation and cell traction stress
  • to determine if phosphorylation of this signaling protein is essential for mesenchymal stromal cell (MSC) derived therapeutic efficacy

Biochem/physiol Actions

FR180204 is a potent, cell-permeable, ATP-competitive inhibitor of ERK1 and ERK2 (mitogen-activated protein kinase (MAPK)/extracellular-signal-regulated kinases (ERK) 1/2).
It can be used to study the roles of ERK as well as for drug development.

The anti-proliferative activity of dietary flavonoid fisetin has been validated in various cancer models. Establishing its precise mechanism of action has proved somewhat challenging given the multiplicity of its targets. We demonstrated that YB-1 promotes epithelial-to-mesenchymal transition and its inhibition

Natural killer (NK) cells express receptors specific for MHC class I (MHC-I) molecules involved in "missing-self" recognition of cancer and virus-infected cells. Here we elucidate the role of MHC-I-independent NKR-P1B:Clr-b interactions in the detection of oncogenic transformation by NK cells.
