Abstract
Background
Many types of oncolytic viruses (OVs) were enrolled in clinical trials. Recently, an OV named Talimogene laherparepvec approved for the treatment of melanoma. This achievement highlighted the clinical application of OVs. Scientists focus on using these anticancer agents in combination with the current or/and new anticancer chemotherapeutics. They aim to increase the oncolytic effect of a new approach for the treatment of cancer cells.
Objectives
The present study aimed to assess the anticancer impacts of ReoT3D, irinotecan (CPT-11), and napabucasin (BBI608) against murine colorectal cancer cells (CT26). They are assessed alone and in combination with each other.
Methods
Here, oncolytic reovirus was propagated and titrated. Then MTT assay was carried out to assess the toxicity of this OV and chemotherapeutics effect on CT26 cells. The anticancer effects of ReoT3D, CPT-11, and BBI608, alone and simultaneously, on CT26 cell line, were assessed by the induction of apoptosis, cell cycle arrest, colony-forming, migration, and real-time PCR experiments.
Results
Alone treatment with ReoT3D, CPT-11, and BBI608 led to effectively inducing of apoptosis, cell cycle arrest, and apoptotic genes expression level and significantly reduce of colony-forming, migration, and anti-apoptotic genes expression rate. Importantly, the maximum anticancer effect against CT26 cell line was seen upon combination ReoT3D, CPT-11, and BBI608 treatment.
Conclusion
The present study highlights that combination of ReoT3D, CPT-11, and BBI560 showed synergistic anticancer activity against CT26 cell line. This modality might be considered as a new approach against colorectal cancer (CRC) in the in vivo and clinical trial investigations.
