Of primary importance for IPTLD ®, cancer cell membranes also have six times more insulin receptors and ten times more IGF receptors, per cell, than the membranes of host normal tissues. Further, insulin can cross-react with and activate cancer cell IGF receptors. Thus, per cell, cancer has sixteen times more insulin-sensitive receptors than normal tissues. As ligand effect is a function of receptor concentration, these facts serve to differentiate cancer from normal cells – a vital consideration for the safety of cancer chemotherapy. In light of these revelations, exogenous insulin acts to enhance anticancer drug cytotoxicity, and safety, via:
1) A membrane permeability effect to increase the intracellular dose intensity of the drugs;
2) An effect of metabolic modification to increase the S-phase fraction in cancer cells, enhancing their susceptibility to cell-cycle phase-specific agents, and;
3) an effect of biochemical differentiation based on insulin receptor concentration that focuses the first two insulin effects predominantly on cancer cells, sparing host normal tissues.
