Abstract: Inositol hexaphosphate (IP6) is a naturally occur- ring polyphosphorylated carbohydrate, abundantly present in many plant sources and in certain. While IP-6 is found in rice bran and other foods, there are good reasons to take an IP-6 & Inositol supplement. First, IP-6 is getter absorbed in pure form without.

A striking anticancer effect of IP6 was demonstrated in different experimental models. Recently IP 6 has received much attention for its role in cancer prevention and control of experimental tumor growth, progression, and metastasis.

Although experts in the field of nutrition and cancer have been performing in vivo experiments by adding IP 6 to the diet, in all our cancer prevention studies, IP 6 was given via drinking water in concentrations ranging from 0. Studies using other experimental models showed that antineoplastic properties of IP 6 were not restricted to the colon.

Enhanced immunity and antioxidant properties also contribute to tumor cell destruction. Because it is abundantly present in regular diet, efficiently absorbed from the gastrointestinal tract, and safe, IP 6 holds great promise in our strategies for the prevention and treatment of cancer. Similar results were seen in the metastatic lung cancer model Inositol hexaphosphate IP6 is a naturally occurring polyphosphorylated carbohydrate that is present in substantial amounts in almost all plant and mammalian cells.

A reduced tumor growth rate was noticed overall and in some cases a regression of lesions was noted.

Cancer inhibition by inositol hexaphosphate (IP6) and inositol: from laboratory to clinic.

The difference in total number of tumors, tumor burden No. Role of renin-angiotensin system antagonists in the prevention of bevacizumab and sunitinib mediated cardiac dysfunction. Rice bran treatment for patients with hypercalciuric stones: Inositol is ihositol a natural constituent possessing moderate anticancer activity.

This modulation in binding and the activity of basic fibroblast growth factor is thought to be due to the chair conformation of IP 6 mimicking that of the pyranose ring structure in heparin Therefore, IP 6 can reduce carcinogenesis mediated by active oxygen species and cell inoistol via its antioxidative function.

Although normal cells divide at a controlled and limited rate, malignant cells escape from the control mechanisms that regulate the frequency of cell multiplication and usually have lost the checkpoint controls that prevent replication of defective cells. IP 6 may serve as a natural antioxidant 11 and possibly as a neurotransmitter Additionally, the preexisting liver cancers regressed when they were treated directly with IP 6 Oxford University Press is a department of the University of Oxford.

Myo-inositol itself was also demonstrated to have anticancer function, albeit modest. Dietary effects on phytate excretion. The phosphate grouping in positions 1, 2, and 3 axial-equatorial-axial is unique for IP 6providing a specific interaction with iron to completely inhibit its ability to catalyze hydroxyl radical formation, making IP 6 a strong antioxidant, probably still the only role of IP 6 that is widely recognized and accepted.

Protection against cancer by dietary IP6 and inositol.

Because of the highly charged nature of IP 6it was a common misconception that it could not be transported into the cells. Adapted from Vucenik et al.

We found that inositol alone or in combination with IP 6 can prevent the formation and incidence of several cancers in experimental animals: Inositol-phosphate-induced enhancement of natural killer cell activity correlates with tumor suppression.

Although IP 6 may belong to almost all previously mentioned categories of cancer preventive drugs, affecting almost all phases of cancer prevention, it still appears that IP 6 is not a direct antagonist to the carcinogen because of its moderate efficacy in vitro when tested and compared with other chemopreventive agents 30 and a lack of dramatic decrease in cancer incidence when tested in vivo.

An antagonist of fibroblast growth factor receptor binding and activity. Inositol phosphates are versatile molecules with important roles in controlling diverse cellular activities 9 Modulatory influence of arecoline on the phytic acid-altered hepatic biotransformation system enzymes, sulfhydryl content and lipid peroxidation in a murine system. However, because cancer prevention is a long process, a long administration of cancer preventive agent is generally needed, requiring usually 10—40 y of continuous treatment 273and, therefore, it is very important that cancer preventive agents have low or almost no toxicity.

In addition to reducing cell proliferation, IP6 increases differentiation of malignant cells, often resulting in a reversion to normal phenotype.

IP 6 inhibited the growth and differentiation of endothelial cells 6672 and inhibited the secretion of vascular endothelial growth factor from malignant cells 2766 Inositol hexaphosphate inhibits growth, and induces G1 arrest and apoptotic death of prostate carcinoma DU We hypothesized that one of the several ways by which IP 6 plus inositol exerts its action is via lower-phosphate inositol phosphates.

IP 6 is a natural compound and an important dietary component. Inositol occurs ubiquitously in cell membranes in conjugation with lipids, as phosphatidylinositol.

The data strongly argue for the use of IP6 plus inositol in our strategies for cancer prevention and treatment. IP 6 inhibits agonist-induced platelet aggregation 82 and efficiently protects myocardium from ischemic damage and reperfusion injury 83 inosktol, both of which are important for the management of cardiovascular diseases.

Growth inhibition and differentiation inositkl HT cells in vitro by inositol hexaphosphate phytic acid. Comparative toxicities of selected minor dietary non-nutrients with chemopreventive properties.

The phosphate grouping in positions 1,2,3 axial-equatorial-axial is unique to IP 6specifically interacting with iron to completely inhibit its ability to catalyze hydroxyl radical formation, making IP 6 a strong antioxidant.

Possible mechanisms of the cancer preventive action of IP 6 include carcinogen blocking activities, antioxidant activities, and antiproliferation and antiprogression activities The antioxidant activity of IP 6 is widely accepted and indisputable 11and IP 6 possesses antiproliferative and antiprogression activities. Chromatographic analysis of tumor tissue revealed the presence of inositol and IP 1similar to plasma.

Value of IP 6 as a therapeutic and preventive agent for cancer. A Randomized Controlled Trial. The most consistent and best anticancer results were obtained from the combination of IP 6 plus inositol. However, the effectiveness and safety of IP 6 plus inositol at therapeutic doses needs to be determined in phase I and phase II clinical trials in humans.

Aberrant crypts correlate with tumor incidence in F rats treated with azoxymethane and phytate. Uncontrolled proliferation is a hallmark of malignant cells, and IP 6 can reduce the cell proliferation rate of many different cell lines of different lineage and of both human and rodent origin 3 — 5262831 — 33 Enhanced immunity and antioxidant properties can also contribute to tumor cell destruction.

Protection against cancer by dietary IP6 and inositol.

IP 6 was also potent in inhibiting experimental hepatoma 31 Another important aspect of cancer treatment is overcoming acquired drug resistance. Inositol hexaphosphate reduces O-tetradecanoylphorbolacetate-induced ornithine decarboxylase independent of protein kinase C isoform expression in keratinocytes. Inositol and inositol hexaphosphate suppress cell proliferation and tumor formation in CD-1 mice.
