Effect of S1P and S2P inhibitors on GSK343-induced SREBP2 processing. A. HepG2 and PLC5 cells were pretreated with AEBSF for 1 h and then exposed to GSK343 for 6 h. The whole cell lysates were analyzed by Western blotting. B. HepG2 and PLC5 cells were pretreated with PF-429242 or Nelfinavir for 1 h and then exposed to GSK343 for 6 h. The whole cell lysates were analyzed by Western blotting. C. HepG2 and PLC5 cells were treated with GSK343 with or without 10 μM PF-429242 for 72 h. Cell viability was analyzed by MTS assay.
