Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Background:

Precision medicine relies on accurate molecular disease classification.
Current methods struggle to integrate multiple molecular data types for classification.
In silico classifiers offer potential but face implementation challenges.

Purpose of the Study:

To develop a DNA-encoded molecular classifier for processing multidimensional molecular clinical data.
To enable unified electrochemical sensing signals for heterogeneous molecular binding events.
To create a system for weighted bioanalysis of complex molecular information.

Main Methods:

Utilized DNA-framework-based programmable atom-like nanoparticles with 'n' valence.
Developed valence-encoded signal reporters for linear translation of binding events to signal gains.
Implemented the classifier for biomarker panel screening and analysis.

Main Results:

Demonstrated a molecular classifier based on programmable atom-like nanoparticles.
Successfully analyzed a panel of six biomarkers across three-dimensional data types.
Achieved near-deterministic molecular taxonomy of prostate cancer patients.

Conclusions:

The developed DNA-encoded classifier physically implements computational classification of multidimensional data.
Programmable nanoparticles provide a versatile platform for unified signal transduction.
This approach advances molecular taxonomy for precision diagnostics, exemplified by prostate cancer stratification.
