Solution Overview

Problem

Current methods for determining the cellular function associated with an active NFkB cellular signaling pathway are inadequate, as they only indicate pathway activity without specifying the underlying function, which is crucial for therapeutic decisions, especially in cancer treatment where blocking NFkB activity may have contrasting effects depending on its functional state.

Innovation Solution

A method involving the determination of expression levels of specific NFkB target genes, such as BCL2, BCL2L1, CCND2, SKP2, CYP27B1, IGHE/IGHG1, BIRC3, CCL2, GZMB, SOD2, and MMP1, to identify the cellular function of an active NFkB pathway, allowing for differential expression analysis to determine cell division, apoptosis, or oxidative stress protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If NFkB pathway activity is determined using conventional methods, then pathway activity status is identified, but the specific cellular function remains unspecified

Engineering Contradiction:
Improvecellular function informationVSAvoidgene expression analysis system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The NFkB target genes are segmented into three distinct functional groups: cell division genes (BCL2, BCL2L1, CCND2, SKP2, CSF1, NOX1, SERPINE2), apoptosis genes (CYP27B1, IGHE, IGHG1), and oxidative stress protection genes (BIRC3, CCL2, GZMB, SOD2, CCL5, MMP1). By analyzing expression levels within each group separately, the method identifies which specific cellular function is driven by the active NFkB pathway, thereby recovering the lost functional information without requiring an overly complex system.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If NFkB pathway is blocked in cancer treatment, then tumor growth may be inhibited, but immune response may be compromised

Engineering Contradiction:
Improvetherapeutic strategy adaptabilityVSAvoidtherapeutic outcome predictability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The method applies local quality by determining the specific cellular function (cell division, apoptosis, or oxidative stress protection) driven by the NFkB pathway in each patient's tumor cells. This functional characterization allows for tailored therapeutic approaches: tumors with dominant cell division signatures may benefit from NFkB inhibition, while those with apoptosis or oxidative stress signatures may require alternative strategies or combination therapies, thereby improving both adaptability and predictability of therapeutic outcomes.

Principle #3Local quality
