Figure 6: Snail overexpression restored cells migration and invasion abilities attenuated OXA sensitized by Neferine treatment.

(a,b) Migration and invasion abilities suppressed by Neferine treatment were restored by Snail overexpression. HepG2 and Bel-7402 cells were pre-treated with or without 10 μM Neferine and then transfected by pcDNA3.1-Snail and pcDNA3.1-NC vectors for 48 hrs, respectively. #: pcDNA3.1-NC + Nef vs. pcDNA3.1-NC, p < 0.05, respectively; + : pcDNA3.1-Snail vs. pcDNA3.1-NC, p < 0.01, respectively; Δ: pcDNA3.1-Snail + Nef vs. pcDNA3.1-Snail, p < 0.01, respectively. (c) OXA sensitization by Neferine treatment was eliminated by Snail overexpression in HepG2 and Bel-7402 cells. (d) OXA sensitization by Neferine treatment was eliminated by 10 ng/ml TGF-β1 in HepG2 and Bel-7402 cells. #: Nef + OXA vs. OXA, p < 0.01, respectively; +: Nef + OXA + TGF-β1 vs. Nef + OXA, p < 0.001, respectively. *p < 0.05, **p < 0.01, ***p < 0.001.
