Nanoflare Couple: Multiplexed mRNA Imaging and Logic-Controlled Combinational Therapy

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Cancer Research

Background:

• Theranostics, combining diagnosis and therapy, is crucial for personalized cancer treatment but faces challenges.
• Developing integrated platforms for simultaneous molecular imaging and targeted therapy remains an unmet need.

Purpose of the Study:

• To develop a versatile nanotheranostic platform, termed nanoflare couple (NC), for in situ multiplex cancer-related mRNA imaging.
• To achieve logic-controlled gene therapy and photothermal therapy for breast cancer treatment.

Main Methods:

• Designed the NC platform utilizing TK1 and survivin mRNAs as targets for imaging and therapy triggers.
• Employed gold nanoparticles aggregation for therapeutic response upon infrared light irradiation.
• Validated efficacy using in vitro and in vivo assays in a mouse model with MCF-7 breast cancer cells.

Main Results:

• The NC platform enabled multiplexed mRNA imaging of cancer-related biomarkers.
• Demonstrated high efficiency in logic-controlled combinational therapy (gene and photothermal therapy).
• Successfully treated breast cancer in a preclinical mouse model.

Conclusions:

• The developed nanoflare couple (NC) platform offers a promising theranostic approach for personalized cancer treatment.
• This integrated system provides simultaneous molecular imaging and targeted therapeutic intervention.
• The NC platform shows significant potential for advancing breast cancer therapy.
