    This study introduces a new method to estimate cellular M monomer (PM) distribution from lactate dehydrogenase (LD) isoenzyme patterns. This approach offers a more fundamental cellular biochemistry characterization than traditional LD analysis.

    Area of Science:

    • Biochemistry
    • Cell Biology
    • Biophysics

    Background:

    • Lactate dehydrogenase (LD) isoenzymes are released from cells and their patterns in serum or interstitial fluid can indicate cellular status.
    • The current analysis of LD patterns is often limited to simple inspection or statistical methods.

    Purpose of the Study:

    • To develop a novel method for inferring cellular M monomer (PM) distribution from serum or interstitial fluid LD isoenzyme patterns.
    • To demonstrate that PM distribution provides a more fundamental characterization of cellular biochemistry compared to LD patterns.

    Main Methods:

    • Developed a method to mathematically infer the distribution of the cellular parameter PM (fraction of M monomer) from LD isoenzyme patterns.
    • Applied the developed method to existing LD patterns from scientific literature.

    Main Results:

    • The method successfully infers the estimated distribution of PM in the cell population based on LD isoenzyme patterns.
    • The inferred PM distribution offers a deeper insight into cellular biochemistry than direct analysis of LD patterns.

    Conclusions:

    • The proposed method provides a more fundamental understanding of cellular biochemistry by analyzing LD isoenzyme patterns.
    • This approach offers advantages over traditional methods for analyzing LD patterns, enabling more robust cellular characterization.
