Transcription factor AP-2? plays an important role in human cancer, but its
clinical significance in hepatocellular carcinogenesis is largely unknown.
Methods: AP-2? expression was detected in human hepatocellular cancer (HCC)
tissues and cell lines. The effects of AP-2? on HCC proliferation, migration,
invasion, tumor formation and metastasis were evaluated by MTT, colony formation
and transwell assays in vitro and mouse experiments in vivo. The association
between AP-2? and miR-27a/EMT markers in HCC cell lines and tissues was analyzed.
Results: AP-2? expression was decreased in HCC tissues and cell lines. Reduced
expression of AP-2? was significantly associated with more advanced tumor stages
and larger tumor sizes. The overexpression of AP-2? reduced HCC proliferation,
migration, invasion, tumor formation and metastasis in vitro and in vivo.
Additionally, AP-2? overexpression increased the sensitivity of HCC cells to
cisplatin. Moreover, AP-2? modulates the levels of EMT markers through Slug and
Snail in HCC cell lines and tissues. Furthermore, oncogenic miR-27a inhibits
AP-2? expression by binding to the AP-2? 3' untranslated region (UTR) and
reverses the tumor suppressive role of AP-2?. Conclusion: These results suggested
that AP-2? is lowly expressed in HCC by inhibiting EMT signaling to regulate HCC
cell growth and migration. Therefore, AP-2? in the novel miR-27a/AP-2?/Slug/EMT
regulatory axis enhances the chemotherapeutic drug sensitivity of HCC and might
represent a potential target for evaluating the treatment and prognosis of human
HCC.
