Upconversion Nanoparticle-Anchored Metal-Organic Framework Nanostructures for Remote-Controlled Cancer Optogenetic...

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Oncology

Background:

• Optogenetics offers precise control of cellular functions but has limited cancer therapy research.
• Current cancer therapies face challenges in targeting deep tissues noninvasively.

Purpose of the Study:

• To develop a remote-controlled optogenetic cancer therapy strategy.
• To synergistically combine optogenetics with ion therapy for enhanced cancer treatment.
• To enable noninvasive manipulation of cellular activities in deep tissues using near-infrared light.

Main Methods:

• Synthesized water-dispersible upconversion nanoparticle (UCNP)-metal-organic framework (MOF) nanohybrids.
• Delivered plasmid DNA to cancer cells for in situ photoactivatable cation channel expression.
• Utilized pH-responsive MOFs for metal cation release and UCNPs for near-infrared light activation.

Main Results:

• Demonstrated effective remote-controlled optogenetic cancer therapy across multiple tumor models (colon, breast).
• Achieved noninvasive manipulation of cellular activities in deep tissues and living animals.
• Successfully activated cation channels and facilitated metal cation influx for ion therapy.

Conclusions:

• The developed nanohybrid system represents a significant advancement for optogenetics in clinical cancer therapy.
• This synergistic approach shows substantial potential for future cancer treatment strategies.
• Pioneered a method for remote, noninvasive, and precise cancer treatment using light-activated ion therapy.
