Fig. 6. Inhibition of JNK prevents hexadecenal-induced cytoskeletal reorganization and apoptosis.
A, NIH3T3 cells were cultured in 8-chamber slides for 24 h. Cells were serum deprived for 3 h in the absence or presence of a JNK inhibitor V (JNK Inhib, 20 μM), then cells were treated with vehicle (a-c) or hexadecenal (25 μM) (d-i) for 30 min. F-actin was labeled with Phalloidin-Rhodamine and cells were counter stained with DAPI. B, Cells were cultured in 10-cm culture dishes for 24 h. Cells were serum deprived for 3 h in the presence or absence of a JNK inhibitor V (JNK inhib, 20 μM), then cells were treated with vehicle or hexadecenal (25 μM) for 3 h. Cells were harvested and whole cell extracts were immunoblotted with PARP, phospho-C-Jun or actin antibodies. Immunoblots are representative of at least three independent experiments.
