| 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. |
