Mechanism of CTP/CDDP inhibiting tumor metastasis. a Immuno-fluorescence of EMT markers in 4T1 cells after administration with PBS, free CDDP, TD, TD/CDDP, TP/CDDP or CTP/CDDP for 24 h. b Western blot of indicated proteins expression in hypoxic 4T1 cells after 24 h incubation with different drugs. c The expression of relative proteins was calculated by the signal intensity of protein bands. Cells treated with PBS were used as control. Data are expressed as mean ± SD (n = 3), *p < 0.05, **p < 0.01, ***p < 0.001
