Abstract

Immunogene therapy is a novel method for the treatment of colorectal cancer. Cytokine IL-15 has exhibited therapeutic anticancer potential due to its immune-stimulation property. However, conventional IL-15-based cancer gene therapy studies have been performed using the plasmid DNA form, which has potential shortcomings including weak delivery efficiency and backbone effect. In this study, an IL-15 immunogene therapy study for colon cancer using in vitro transcript mRNA is described. A protamine/liposome system (CLPP) is developed to provide efficient condensation and delivery capacity for in vivo mRNA transportation. They demonstrated that the prepared CLPP system could deliver the IL-15-encoding mRNA into C26 cells with high efficacy. The secretory expressed IL-15 cytokine by the C26 cells successfully produced lymphocyte stimulation and triggered anticancer cytotoxicity upon cancer cells in vitro . Local or systemic administration of the CLPP/mIL-15 complex exhibited obvious inhibition effects on multiple C26 murine colon cancer models with inhibition rates of up to 70% in the C26 abdominal cavity metastasis tumor model, 55% in the subcutaneous model, and 69% in the pulmonary metastasis model, demonstrating high efficacy and safety. These results successfully demonstrated the high therapeutic potential of the CLPP/mIL-15 complex for colorectal cancer immunogene therapy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
