p38 MAPK pathway does not influence the LPA induced AMPK phosphorylation in microglia cells..
By lisha joshi on 06/18/2019
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: BV2 microglia cells

We investigate the effect of LPA on microglia metabolic states. Trying to unravel possible pathways that maybe involved in this process, we used LPAR inhibitors and downstream inhibitors of MAPKs pathway. SB 203580 was used at a concentration of 10µM yet couldn't inhibit the expression of pAMPK. However the inhibitor was well tolerated by the cells.

Species: Human
Cell Line/Tissue: Osteosarcoma

MG-63 cells were pre-incubated with 10 µM SB 203580 for 30 min followed by treatment with 10 µM LPA for 3 h to follow COX-2 expression using Western blot. SB 203580 inhibited COX-2 induction by LPA.

SB 203580 blunts 15d-PGJ2 induced pp38 expression.
By Chintan Koyani on 10/13/2018
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: HL-1 cardiomyocytes

HL-1 cells were incubated with p38 MAPK inhibitor (10 µM SB203580, 25 µMPD169316) or p42/44 MAPK kinase inhibitor (25 µM PD98059) for 30 min prior to 15dPGJ2 treatment (15 µM, 1 h). Immunoreactive bands for pp38 and pp42/44 MAPK expressions were followed by Western blot. SB203580 completely inhibited 15d-PGJ2 induced p38 phosphorylation (shown in Image).
