Applicazioni
U0126 ethanolate has been used as an MEK inhibitor in mononucleated myogenic cells derived from breast muscles of chicken embryos. U0126 has also been used to study ERK2 function in amyloid precursor protein (APP) knockout (KO) mice neurons.
Azioni biochim/fisiol
U0126 is a specific inhibitor of MEK1 and MEK2 (MAP kinase kinase; MAPKK); also inhibits a constitutively active, mutant form of MEK.
U0126, 1,4-diamino-2,3-dicyano-1,4-bis[2-aminophenylthio] butadiene, is a highly selective inhibitor of both MEK1 and MEK2. U0126 was found to functionally antagonize AP-1 transcriptional activity via noncompetitive inhibition of the dual specificity kinase MEK with IC50 of 72 nM for MEK1 and 58 nM for MEK2. U0126 inhibited anchorage-independent growth of Ki-ras-transformed rat fibroblasts by simultaneously blocking both extracellular signal-regulated kinase (ERK) and mammalian target of rapamycin (mTOR)-p70(S6K) pathways. The effects of U0126 on the growth of eight human breast cancer cell lines shown that U0126 selectively repressed anchorage-independent growth of MDA-MB231 and HBC4 cells, two lines with constitutively activated ERK. Loss of contact with substratum triggers apoptosis in many normal cell types, a phenomenon termed anoikis. U0126 sensitized MDA-MB231 and HBC4 to anoikis, i.e., upon treatment with U0126, cells deprived of anchorage entered apoptosis.
