Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If comprehensive genomic and proteomic analyses are performed to assess cellular signaling pathway activity, then measurement precision is improved, but device complexity and data processing difficulty increase
Solution Approach 1:
The patent segments the complex genomic and proteomic data into specific gene expression profiles associated with cellular signaling pathways. By dividing the large dataset into pathway-specific gene signatures, the system maintains high measurement precision while reducing processing complexity through focused analysis of relevant gene sets rather than comprehensive genome-wide data.
Solution Approach 2:
The patent introduces computational algorithms as intermediaries that process raw genomic and proteomic data into interpretable pathway activity scores. These algorithms serve as mediators between complex data generation technologies and clinical decision-making, transforming high-dimensional data into actionable insights without requiring direct complex data processing by clinicians.
2Productivity
If linear combinations of target gene expressions are used to infer pathway activity, then data processing efficiency is improved, but measurement precision may be reduced
Solution Approach 1:
The patent transforms raw gene expression data into standardized pathway activity scores through mathematical transformations including linear combinations and normalization. By changing the parameter representation from individual gene expressions to composite pathway scores, the system achieves efficient processing while maintaining precision through statistically robust transformation methods that preserve biological signal.
3Measurement precision
If multiple target genes are analyzed to determine transcription factor levels, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent merges expression data from multiple target genes into a unified transcription factor activity metric through linear combinations. By combining information from multiple genes into a single composite measure, the system maintains high measurement precision through multi-parameter assessment while reducing complexity by presenting a consolidated result rather than requiring interpretation of multiple individual gene expressions.

AI summary
The present application mainly relates to specific methods for inferring activity of a cellular signaling pathway in tissue and/or cells of a medical subject based at least on expression levels of one or more target gene(s) of the cellular signaling pathway measured in an extracted sample of the tissue and/or cells of the medical subject, an apparatus comprising a digital compressor configured to perform such methods and a non-transitory storage medium storing instructions that are executable by a digital processing device to perform such methods.
