Article Title: Metformin induces apoptosis and inhibits migration by activating the AMPK/p53 axis and suppressing PI3K/AKT signaling in human cervical cancer cells

doi: 10.3892/mmr.2020.11725

Figure Lengend Snippet: Metformin inhibits cervical cancer cell proliferation and migration. (A) CaSki, C33A and HeLa cells were treated with metformin (0–20 mM) for 48 h. Cell viability was determined by performing the Cell Counting Kit-8 assay. (B) CaSki, C33A and HeLa cells were treated with metformin (0–10 mM) for 48 h. Cell migration was assessed by performing a Transwell migration assay (scale bar, 200 µm). Data are presented as the mean ± SD from three independent experiments. *P<0.05 vs. CON.
