TMPyP4 activated the p38 MAPK signaling pathway in human cervical cancer cells. Human cervical cancer cells or human normal cervical cells were treated with 20 μM TMPyP4 for 24 h, the protein expression level of p38 MAPK and p-p38 MAPK was measured by Western blot (a). Band density was analyzed using Image J software (b). Data are expressed as mean ± SD of three independent experiments in triplicate. *P < 0.05 or **P < 0.01 indicates significance, P > 0.05 means no difference
