Solution Overview

Problem

Current methods are inadequate in modulating the epithelial-mesenchymal transition (EMT) process, particularly in inducing or inhibiting EMT programs in cancer cells, which are crucial for understanding and treating malignancy and metastasis.

Innovation Solution

The development of compositions and methods that modulate signaling pathways, including TGF-beta, canonical and non-canonical Wnt pathways, and BMP signaling, to induce or inhibit EMT by stimulating or inhibiting specific autocrine and paracrine signaling pathways, thereby controlling the epithelial-mesenchymal transition and maintaining a mesenchymal and stem cell-like state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional techniques are used to study EMT, then basic cellular processes can be observed, but effective modulation of EMT programs in cancer cells is inadequate

Engineering Contradiction:

Improveeffectiveness of EMT modulationVSAvoidability to induce or inhibit EMT programs

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent combines multiple signaling pathway modulators (TGF-beta, Wnt, BMP pathways) and cell adhesion perturbing agents into a single composition. This merging of multiple therapeutic mechanisms into one formulation enables effective EMT modulation in cancer cells, overcoming the inadequacy of conventional single-agent approaches.

Inventive Principle:

Principle #5Merging (Combining)

2Speed

If EMT programs are induced in cancer cells, then migratory ability is enhanced, but tumor-initiating and metastatic capabilities increase

Engineering Contradiction:

Improvemigratory ability of cellsVSAvoidtumor-initiating and metastatic capabilities

Core Design Contradiction:

SpeedVSObject-generated harmful factors

Solution Approach 1:

The patent uses compounds that precisely modulate signaling pathway parameters (TGF-beta, Wnt, BMP) and cell adhesion properties to control the EMT process. By adjusting these parameters through specific compound concentrations and combinations, the therapy enhances migratory ability while suppressing harmful tumor-initiating and metastatic capabilities through balanced pathway modulation.

Inventive Principle:

3Reliability

If multiple signaling pathways are targeted simultaneously, then EMT modulation effectiveness is improved, but composition complexity increases

Engineering Contradiction:

ImproveEMT modulation effectivenessVSAvoidcomposition structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple signaling pathway modulators and cell adhesion perturbing agents into a single integrated composition. This consolidation approach maintains effectiveness in modulating EMT by targeting multiple pathways simultaneously while simplifying the overall therapeutic intervention into one administrable formulation.
