Lycium barbarum Polysaccharides Protect against Trimethyltin Chloride-Induced Apoptosis via Sonic Hedgehog and PI3K/Akt Signaling Pathways in Mouse Neuro-2a Cells

Figure 4

TMT-induced Shh and PI3K/Akt inhibition. N2a cells were incubated with 1.875, 3.75, and 7.5 μM TMT for 24 h. Different protein expressions levels were determined through Western blot analysis. The results are expressed as fold increases of optical density with the internal control. The mean protein expression of control group is designated as one in the graph. Each bar represents mean ± SD (). , compared with the control group.
