Effect of UaB fraction
on LPS-induced nuclear translocation of
NF-κB in RAW 264.7 macrophages. The cells were treated with
80 ng/mL UaB for 1 h prior to treatment with 100 ng/mL LPS for 30
min. Cells were pretreated with 80 ng/mL UaB for 1 h prior to stimulation
with 100 ng/mL LPS for 30 min (A). Localization of NF-κB p65
was visualized following immunofluorescence staining with anti-NF-κB
p65 antibody (red). The cells were also stained with DAPI for visualization
of nuclei (blue). The cells were visualized using a fluorescence microscope
(magnification, ×400). Cells were pretreated with 80 ng/mL UaB
for 1 h prior to stimulation with 100 ng/mL LPS for 30 min (B). Nuclear
and cytosolic proteins were subjected to 10% SDS-PAGE followed by
western blot analysis using anti-NF-κB p65 and IκB antibodies.
Lamin B and actin were used as internal controls for the nuclear and
cytosolic fractions, respectively. NF, nuclear factor; IκB,
inhibitor of NF-κB; and LPS, lipopolysaccharide.
