    Summary

    Surface potential (SP) changes correlate with cell membrane potential (MP) shifts across physiological states. Cancer development alters this relationship, indicating potential diagnostic markers.

    Area of Science:

    • Biophysics
    • Cellular Electrophysiology
    • Oncology

    Context:

    • Investigating the relationship between cell membrane potential (MP) and surface potential (SP) in different physiological conditions.
    • Understanding how these electrical properties change during induced cancerogenesis (IC) and total reaction to damage (TRD).
    • Establishing baseline electrical characteristics in control (C) organisms.

    Purpose:

    • To elucidate the linear correlation between SP and MP alterations.
    • To characterize the distinct SP-MP relationships observed in control, IC, and TRD states.
    • To identify potential electrophysiological markers for early cancer detection.

    Summary:

    • A linear connection exists between surface potential (SP) and cell membrane potential (MP) in control, induced cancerogenesis (IC), and total reaction to damage (TRD) states.

  • In control states, significant SP changes correspond to minor MP changes (100% SP vs. 20% MP).
  • TRD shows a reversed relationship (20% SP vs. 100% MP), while early IC reveals a unique pattern (20% SP decrease with 60% MP increase).

    • Impact:

    • This research highlights the differential electrophysiological responses of cells under various physiological conditions.
    • The distinct SP-MP relationship during early IC suggests potential for novel, non-invasive diagnostic approaches.
    • Findings contribute to a deeper understanding of cellular electrical behavior in disease states.
