Abstract
Background: Cancer is a major cause of death worldwide. Colorectal cancer is the second most common type. Additional treatments like chemotherapy and radiation therapy may be recommended. Developing new techniques is vital due to drug resistance and a lack of targeted therapies.
Objective: In this study, the effects of mesenchymal stem cells (MSCs) loaded with oncolytic Coxsackievirus A21 (CVA21) on a mouse model of CRC were investigated.
Methods: The therapeutic potency of MSCs loaded with oncolytic CVA21 were evaluated in an experimental mouse model of colorectal cancer which received an injection CT26 cells per mouse subcutaneously. Splenocyte proliferation index, lactate dehydrogenase (LDH) assay, nitric oxide (NO) production assessment, and cytokine assay (IFN-γ, IL-4, IL-10, and TGF-β) in the splenocyte supernatant were all used to evaluate the impact of MSCs loaded with CVA21.
Results: The results of this study showed that the treatment of a mouse model of colorectal cancer with MSCs loaded with oncolytic CVA21 could significantly suppress the tumor growth, which was accompanied by stimulation of splenocytes proliferation index, an increase of NO and LDH. Also, MSCs loaded with oncolytic CVA21 increased the secretion of IFN-γ and decreased the secretion of IL-4, IL-10, and TGF-β.
Conclusion: The results of the current study suggest that MSCs loaded with oncolytic CVA21 therapy for the CRC mouse model may have some potential advantages. On the other hand, the results of the study showed that, in addition to activating the acquired immune system, the use of MSCs loaded with oncolytic CVA21 also stimulates the innate immune system by increasing level of nitric oxide.
期刊介绍：
Current Cancer Drug Targets aims to cover all the latest and outstanding developments on the medicinal chemistry, pharmacology, molecular biology, genomics and biochemistry of contemporary molecular drug targets involved in cancer, e.g. disease specific proteins, receptors, enzymes and genes.
Current Cancer Drug Targets publishes original research articles, letters, reviews / mini-reviews, drug clinical trial studies and guest edited thematic issues written by leaders in the field covering a range of current topics on drug targets involved in cancer.
As the discovery, identification, characterization and validation of novel human drug targets for anti-cancer drug discovery continues to grow; this journal has become essential reading for all pharmaceutical scientists involved in drug discovery and development.
