    This study proposes that exterior-organizer RNA (exoRNA) on cell membranes organizes cell functions. Defects in exoRNA assembly are hypothesized as the primary cause of all malignancies, potentially due to genetic changes.

    Area of Science:

    • Molecular Biology
    • Cell Biology
    • Oncology

    Background:

    • Extensive research on malignant cells yields complex, contradictory data on cancer's molecular basis.
    • A fundamental molecular defect is suspected to drive normal cell transformation into malignant cells.

    Purpose of the Study:

    • To propose a novel hypothesis for the primary molecular defect in all malignancies.
    • To identify exterior-organizer RNA (exoRNA) as a key component in cell surface organization and malignancy.

    Main Methods:

    • Hypothesis formulation based on existing experimental data.
    • Proposing specific genetic alterations (deletion, mutation, viral insertion) affecting exoRNA.
    • Suggesting experimental designs to test the exoRNA hypothesis.

    Main Results:

    • Hypothesis: Exterior-organizer RNA (exoRNA) on the cell membrane organizes critical molecular aggregates.
    • Proposed defect: Impaired exoRNA production or assembly is the root cause of malignancy.
    • Potential causes: Chromosomal deletions, gene mutations, or viral RNA competition affecting exoRNA.

    Conclusions:

    • A defect in exterior-organizer RNA (exoRNA) assembly is proposed as the unifying molecular defect in all cancers.
    • This defect can arise from various genetic alterations, impacting cell surface complex formation.
    • Further experiments are needed to validate the role of exoRNA in cancer development.
