TMPyP4 inhibited cell proliferation in human cervical cancer cells. After cells were treated with 1, 5, 10 or 20 μM TMPyP4 for 24 h, cell proliferation in human cervical cancer cells (a) and human normal cervical cells (b) was measured by MTT assay. Data are expressed as mean ± SD of three independent experiments in six replicates. *P < 0.05 or **P < 0.01 indicates significance, P > 0.05 means no difference
