Physio-mitotic theory and a new concept of cancer development

In the physio-mitotic theory, general mitosis consists of two different types: maturation and duplication. While being co-regulated by mechanisms involving maturation and duplication factors, these two types of mitotic activities each play a respective role in the antagonistic histological development of the other. According to the theory of systematic organization, each type of organic tissue is always developed and established under certain physiological conditions. As an organoid tissue, cancerous tissue must also fundamentally develop according to that theory. Consequently, a new concept of cancer development should be devised based on the physio-mitotic theory.

Physio-mitotic theory and a new concept of leukemia development

In the physio-mitotic theory described previously by the authors (10), general mitosis consists of two different types: essential duplication and converted maturation. These two types of mitosis are regulated by mechanisms involving maturation and duplication factors, and each plays a role in the antagonistic histological development of the other.According to this theory, every kind of leukocyte is produced through mitosis in the bone marrow and migrates during cell turnover to the bloodstream. However, in leukemia a highly excessive number of leukocytes and leuko-blastocysts appear in the bloodstream. This excessive amount is greater than the physiological capability of cells in the bone marrow alone. Such an extremely large group of cells would not be produced without being dependent on an extremely high ratio of produced leukocytes to original stem cells. This extremely high ratio may be due to a systematic pathological deterioration of the mitotic maturation ability during the maturation process of the leuko-blastocysts. Consequently, restoration of the deterioration to the original mitotic maturation response of the normal leuko-blastocysts may be an essential event in achieving leukemia eradication, rather than persistent destruction of individual leukemic leukocytes.

The use of ionized iodine for cancer prevention and eradication

Using an ionized iodine compound, it may be possible to transmit a weak effect of the digestive enzymes from the duodenal lumen to the cytoplasmic structures beyond the cell membrane in general organic tissues. Povidone-iodine is easily obtainable at present, and may be the most suitable ionized material for the transmission of the enzymatic effects to body tissues. Consequently, to remove certain cellular byproducts accumulated abnormally in cancerous cytoplasm, and to achieve cancer prevention and eradication, a method of using povidone-iodine, as a conceptual model, should be devised and developed in the future.

Tranilast inhibits transplant-associated coronary arteriosclerosis in a murine model of cardiac transplantation

Accelerated coronary arteriosclerosis remains a major problem for the long-term survival of cardiac transplant recipients. However, the pathogenesis of graft vasculopathy is poorly understood and there is no effective therapy. Tranilast is a promising drug that may prevent post-angioplasty restenosis. Here, we investigated whether orally administered tranilast inhibits the development of intima hyperplasia in a mouse model of cardiac transplantation. Cardiac allografts from BALB/c mice were transplanted heterotopically into C3H/He mice. Mice were administered either vehicle or tranilast everyday by gavage. Morphometrical analysis of the cardiac allografts harvested at 2 months revealed that the administration of tranilast significantly reduced the development of coronary atherosclerosis. In the mice treated with tranilast, up-regulation of the cyclin-dependent kinase inhibitor p21 was observed in the allografts, accompanied by a reduced number of proliferating cells. Tranilast also suppressed transforming growth factor-beta (TGF-beta) expression. Tranilast may be effective in preventing transplant-associated arteriosclerosis through its anti-inflammatory and anti-proliferative effects.
