Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Area of Science:

  • Biomedical Engineering
  • Nanotechnology
  • Catalysis

Background:

  • Nanozyme-based catalytic therapy shows promise for cancer treatment.
  • Nanozyme aggregation into 3D structures often impairs catalytic efficiency.
  • Novel strategies are needed to enhance nanozyme performance in vivo.

Purpose of the Study:

  • To design and investigate nanozyme-based clusterphenes for enhanced cancer catalytic therapy.
  • To explore the synergistic effects of polyoxometalate (POM) and glucose oxidase (GOx) in a layered structure.
  • To evaluate the impact of electric fields on the catalytic activity and therapeutic efficacy.

Main Methods:

  • Assembly of polyoxometalate (POM) and glucose oxidase (GOx) into layered nanozyme clusterphenes with hexagonal pores.
  • Investigation of multi-enzyme activities: peroxidase (POD)-like, catalase (CAT), and glutathione oxidase (GPx).
  • Assessment of nanozyme performance under electrical stimulation using in vitro and in vivo tumor models.

Main Results:

  • The POMG-based clusterphene exhibited significantly enhanced POD-like activity (sevenfold increase under electrical stimulation).
  • Sustained production of reactive oxygen species (ROS) and consumption of tumor glucose by GOx.
  • Demonstrated efficient tumor inhibition and prevention of proliferation in a murine model.

Conclusions:

  • POMG-based clusterphenes offer a promising platform for enhanced nanozyme catalytic therapy.
  • The layered structure and electrical stimulation synergistically boost therapeutic efficacy.
  • This approach holds potential for future cancer treatment strategies.
