Figure 3

Immunofluorescence images of HepG2 cells that were treated with PMA and protopine and analyzed for NF-κB expression. PMA treatment promoted the translocation of NF-κB protein from the cytoplasm to the nucleus of HepG2 cells. When the cells were treated with 200 nM PMA alone, translocation of the NF-κB protein from the cytoplasm to the nucleus occurred. The protopine treatment inhibited the translocation of NF-κB protein from the cytoplasm to the nucleus in HepG2 cells. Scale bar = 5 μm.
