A Theoretical Framework Integrating Calcium Signaling, Six Communication Channels, Hypoxia, ERAP1, CLIC1, and P_state

Most current oncology models ask: “How does a tumor grow?” NOAH6 asks a different question: “How does a tumor maintain the state in which it is allowed to grow?” This paper presents a hierarchical theoretical framework defining the tumor as a pathological autonomous regulatory subsystem (R0''–R5'') that establishes itself within a healthy organism. The model integrates a distributed integration network within individual cells (R3'), Ca²⁺ signaling as a common executive bus, six communication channels (exosomes, TNTs, gap junctions, microvesicles, ATP signaling, apoptotic bodies), the collective regulator R3'', and the permissive asymmetry state P_state. A central consequence is hierarchical vulnerability: interventions at higher levels (R3'', Ca²⁺ signaling, communication channels) are predicted to have disproportionately greater effects than those targeting only the final phenotype (R5''). This paper builds upon our recently published work (Causevic, 2026), in which we presented NOAH6 addressing Question 1 — the proposed mechanism for the emergence of the first tumor clone through loss of multicellular cohesion and derepression of the ancient algorithm (Level 1–5 architecture). The present work focuses on Question 2 — how this initial clone establishes and maintains a self-sustaining systemic disease through the pathological regulatory subsystem R0''–R5'', the collective regulator R3'', and the stabilization of P_state. Together, the two papers outline a coherent two-phase model of carcinogenesis: initiation (Level 1–5) and systemic maintenance (R0''R5''). The model distinguishes confirmed findings from hypotheses, offering several testable predictions, including synergistic ERAP1 and exosome inhibition, and ORAI1 blockade as a potential multi-channel disruptor. Originality lies not in individual mechanisms but in the architecture of their relationships and in the reframing of the central question of cancer biology.
