Abstract

High-mobility group protein two (HMGA2), a nonhistone nuclear-binding protein and its downregulators; vimentin, matrix metallopeptidase-9 (MMP-9), and E-cadherin are shown to contribute to tumor progression and metastasis. Thus, in this study, we checked simultaneous delivery of HMGA-2 siRNA and the anticancer drug doxorubicin to enhance the anticancer treatment effects. For this purpose, we used MTT assay and real-time polymerase chain reaction (RT-PCR). Our results showed that dual delivery of Dox and HMGA-2 siRNA by trimethyl chitosan (TMC) significantly inhibited breast cancer cells growth. Additionally, the delivery of siRNA significantly silenced HMGA-2, vimentin, and MMP9 mRNAs, but led to overexpression of E-cadherin mRNA. © 2016 Informa UK Limited, trading as Taylor & Francis Group.
