BAY-u 3405 inhibits 15d-PGJ2-induced p38 activation.
By Chintan Koyani on 12/10/2018
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: Cardiomyocytes

HL-1 cardiomyocytes were pre-incubated with BAY-u 3405 (2 µM, 30 min) followed by treatment with 15d-PGJ2 (15 µM, 30 min) to follow p38 activation using Western blot analysis. BAY-u 3405 completely abolished 15d-PGJ2-induced p38 phosphorylation.
