    Problems, Progress and Perspectives in Mathematical and Computational Biology · 2026 · DOI

  • The distinction between genetic information patterns that produce robust multicellular organisms versus disordered tissue in cancer is proposed but lacks specification of which eigengenes, which intracellular dynamics controlling protein folding, or which evolutionary selection mechanisms fail or become dysregulated in cancer cell proliferation compared to normal development.

    How Does Genetic Information Enable Life? · 2026 · DOI

  • The paper suggests that non-random cellular interactions during proliferation produce information gain analogous to amino acid interactions in protein folding, but does not specify which cell-cell signaling pathways, which types of non-random interactions, or quantitative metrics should be used to measure information gain during actual tissue morphogenesis and distinguish it from random proliferation.

    How Does Genetic Information Enable Life? · 2026 · DOI

  • The model claims that the 30 billion bits of human genome information must be significantly expanded to form 36 trillion cells, but lacks a detailed calculation or experimental design comparing actual Shannon entropy measurements in genomic sequences versus the information content required for cell-type specification and tissue organization across different developmental stages.

    How Does Genetic Information Enable Life? · 2026 · DOI

  • The paper invokes eigengenes and co-expression patterns of genes in adjacent cells as the proposed biological mechanism for dimensional information expansion during brain development, but does not specify which eigengene patterns, which brain tissues, or at which developmental timepoints this mechanism should be investigated to empirically validate the theoretical model.

    How Does Genetic Information Enable Life? · 2026 · DOI

  • The paper proposes that information gain through dimensional expansion (1D to 3D) applies to multicellular organism development analogous to protein folding, but provides no quantitative framework for measuring Shannon information content during embryonic development stages or validating the information expansion claim empirically in developmental systems beyond the single Choanoeca flexa example.

  • The text emphasizes that molecular recognition and drug binding are dynamic processes involving conformational changes and 'jiggling' of both target and ligand, and that MD simulations reveal protein dynamics beyond X-ray crystallography.

    Computational molecular biology · 2020 · DOI

  • The paper advocates targeting protein-protein interaction edges rather than nodes (hubs) to avoid indiscriminate pathway blockade, and discusses both orthosteric and allosteric disruption mechanisms.

  • The computer output does in fact give some ground for conjecture that groups ( a ) a n d (b) are related to manuscript D in the form: D (b) (a) Beyond this, the results are insufficiently consistent to support even a plausible conjecture, and obvi- ously a larger sample needs to be used in any serious attempt to elucidate the relationships of all the extant texts.

  • The above discussion is necessarily sketchy, but it clearly brings out three important points: (a) an enormous amount of work remains to be done without ever going to multicellular organisms; (b) important problems exist at all levels of complexity; and (c) there is likely to be an increasing demand for large amounts of pure cell components present in the cell in rather small amounts.
