Tanshinone IIA (Tan-IIA) is an extract from the widely used traditional Chinese
medicine (TCM) Danshen (Salvia miltiorrhiza), and has been found to attenuate the
proliferation of bladder cancer (BCa) cells (The IC(50) were: 5637, 2.6 ?g/mL;
BFTC, 2 ?g/mL; T24, 2.7 ?g/mL, respectively.). However, the mechanism of the
effect of Tan-IIA on migration inhibition of BCa cells remains unclear. This
study investigates the anti-metastatic effect of Tan-IIA in human BCa cells and
clarifies its molecular mechanism. Three human BCa cell lines, 5637, BFTC and
T24, were used for subsequent experiments. Cell migration and invasion were
evaluated by transwell assays. Real-time RT-PCR and western blotting were
performed to detect epithelial-mesenchymal transition (EMT)-related gene
expression. The enzymatic activity of matrix metalloproteinases (MMP) was
evaluated by zymography assay. Tan-IIA inhibited the migration and invasion of
human BCa cells. Tan-IIA suppressed both the protein expression and enzymatic
activity of MMP-9/-2 in human BCa cells. Tan-IIA up-regulated the epithelial
marker E-cadherin and down-regulated mesenchymal markers such as N-cadherin and
Vimentin, along with transcription regulators such as Snail and Slug in BCa cells
in a time- and dose-dependent manner. Mechanism dissection revealed that
Tan-IIA-inhibited BCa cell invasion could function via suppressed chemokine (C-C
motif) ligand 2 (CCL2) expression, which could be reversed by the addition of
CCL2 recombinant protein. Furthermore, Tan-IIA could inhibit the phosphorylation
of the signal transducer and activator of transcription 3 (STAT3) (Tyr705), which
cannot be restored by the CCL2 recombinant protein addition. These data
implicated that Tan-IIA might suppress EMT on BCa cells through STAT3-CCL2
signaling inhibition. Tan-IIA inhibits EMT of BCa cells via modulation of
STAT3-CCL2 signaling. Our findings suggest that Tan-IIA can serve as a potential
anti-metastatic agent in BCa therapy.
