Area of Science:

  • Biomarker discovery and validation
  • Translational medicine
  • Computational biology and bioinformatics

Background:

  • Individual biomarkers often lack clinical sensitivity and specificity due to biological variability and non-specific disease processes.
  • Multimarker panels are emerging as a strategy to overcome the limitations of single biomarkers by combining their strengths.
  • Current approaches require optimized methods for selecting markers that comprehensively represent disease pathophysiology.

Purpose of the Study:

  • To outline a procedure for identifying disease-specific pathophysiological processes (units).
  • To enable the selection of optimal biomarker candidates for multimarker panels.
  • To enhance the accuracy of disease diagnosis and prognosis through improved biomarker panels.

Main Methods:

  • Literature mining to identify disease-associated molecular features.
  • Analysis of aggregated, publicly available Omics profiling experiments.
  • Delineation of disease-specific pathophysiological units based on molecular data.

Main Results:

  • A systematic procedure for identifying molecular units representing specific pathophysiological processes was established.
  • This approach facilitates the assignment of existing or selection of novel biomarker candidates to these units.
  • The resulting multimarker panels are expected to provide an improved reflection of clinical phenotypes.

Conclusions:

  • The proposed method enables the rational design of multimarker panels by targeting key pathophysiological processes.
  • This strategy promises to enhance the diagnostic and prognostic accuracy of biomarkers in clinical practice.
  • This approach offers a robust framework for advancing biomarker research and application.
