Abstract

High expression of inhibitor of apoptosis (IAP) molecules in cancer cells promotes cancer cell chemoresistance. Use of BV6, a well-known IAP inhibitor, along with inhibition of signal transducer and activator of transcription 3 (STAT3), which is an important factor in the survival of tumor cells, and NIK as a mediator of BV6 unpredicted side effects, can induce effective apoptosis in tumor cells. The present study has investigated the combination therapy of cancer cells using Carboxymethyl Dextran-conjugated trimethyl chitosan (TMC-CMD) nanoparticles (NPs) loaded with NIK/STAT3-specific siRNA and BV6 to synergistically induce apoptosis in the breast, colorectal and melanoma cancer cell lines. Our results showed that in addition to enhanced pro-apoptotic effects, this combination therapy reduced proliferation, cell migration, colony formation, and angiogenesis, along with expression of factors including IL-10 and HIF in tumor cells. The results indicate the potential of this combination therapy for further investigation in animal models of cancer. © 2020 Elsevier B.V.
