Carcinogenesis--devolution towards an ancient nucleated pre-eukaryotic level
Medical Hypotheses
|November 1, 1984
Summary
Cancer arises from cells devolving to an ancient anaerobic state, driven by mitochondrial damage and maternal inheritance. This evolutionary regression explains the neoplastic process without external carcinogens.
Area of Science:
- Evolutionary Biology
- Cell Biology
- Cancer Research
Background:
- Mitochondria and host cells are obligatory symbionts.
- Cellular evolutionary history is a prerequisite for carcinogenesis.
- Carcinogenesis involves a devolutionary process towards a pre-eukaryotic state.
Purpose of the Study:
- To propose a devolutionary mechanism for cancer.
- To explain the role of mitochondria in inherited neoplastic disposition.
- To elucidate the process of carcinogenesis without external carcinogens.
Main Methods:
- Analysis of mitochondrial damage in early pretumorous stages.
- Investigation of changes in mitochondrial and nuclear cycles.
- Examination of inherited neoplastic disposition linked to maternal mitochondrial inheritance.
Main Results:
- Mitochondrial damage leads to altered respiration and metabolic pathways.
- Prolonged cell replication can initiate cancer in predisposed individuals.
- Maternal inheritance of neoplastic disposition is observed.
- Malignant cells exhibit cytoskeletal abnormalities and process retardation.
Conclusions:
- Carcinogenesis is a devolutionary process rooted in cellular symbiosis and mitochondrial function.
- Inherited mitochondrial defects and physiological cell stress are sufficient for cancer initiation.
- Soil bacterial enzyme adaptability and dormant DNA packages support the proposed mechanism.
