Fig. 4 — STAT1α activation is not under regulation of cPLA₂α or NOX2-NADPH oxidase in the BV-2 microglia cells under LPS stimulation. A representative immunoblot analysis of the kinetics of STAT1α phosphorylation on (a) tyrosine 701 or (b) serine 727 induced with 50 ng/ml LPS. A representative immunoblot analysis of STAT1α phosphorylation on (c) tyrosine 701 or on (d) serine 727 in unstimulated or stimulated with 50 ng/ml LPS for 4 h in the absence or presence of 2 μm pyropheonoe (Pyrro) or 5 μm DPI added to the cells 1 h before stimulation. The intensity of each phosphorylated STAT1α (p-STAT1α) band after quantification by densitometry was divided by the intensity of each STAT1α band and expressed as arbitrary units. The Bar graphs are the mean ± SE from three experiments (***p < 0.0001, n.s. not significant)
