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.

Protection against cancer by dietary IP6 and inositol.

There is clearly enough evidence to justify the initiation of full-scale clinical trials in humans. Inositol phosphates and cell signalling: Inositol hexaphosphate inhibits growth, and induces G1 arrest and apoptotic death of prostate carcinoma DU Inositol occurs ubiquitously in cell membranes in conjugation with lipids, as phosphatidylinositol.

We tested the effect of IP 6 on tumorigenicity and tumor regression in this model. Inhibition of skin cancer by IP 6 in vivo: Enhanced immunity and antioxidant properties can also contribute to tumor cell destruction.

For a long time IP 6 imositol been recognized as a natural antioxidant.

An enhanced antitumor activity without compromising the patient’s quality of life was demonstrated in a pilot clinical trial involving six patients with advanced colorectal cancer Dukes C and D with multiple liver and lung metastasis The most consistent and best anticancer results were obtained from the combination of IP 6 plus inositol. The observed anticancer effect of inositol compounds could be mediated through several other mechanisms.

Protection against cancer by dietary IP6 and inositol.

In addition to being found in plants, IP 6 is contained in almost all mammalian cells, although in much smaller amounts, where it is important in regulating vital cellular functions such as signal transduction, cell proliferation, and differentiation. One important characteristic of malignancy is the ability of inossitol cells to metastasize and infiltrate normal tissue.

A high oat-bran intakes does not impair zinc absorption in human when added to io6 low-fiber animal protein-based diet. Mechanisms of action of IP 6. Antitumor activity of phytic acid inositol hexaphosphate in murine transplanted and metastatic fibrosarcoma, a pilot study.


The data strongly argue for the use of IP6 plus inositol in our strategies inositil cancer prevention and treatment. Besides affecting tumor cells, IP 6 can act on a host by restoring its immune system.

Protection of ischemic heart from reperfusion injury by myo -inositol hexaphosphate, a natural antioxidant. When [ 3 H]-IP 6 was administered intragastrically to rats, it was quickly absorbed from the stomach and upper intestine and distributed to various organs as early as 1 h after administration Chromatographic analysis of tumor inosktol revealed the presence of inositol and IP 1similar to plasma.

Inositol hexaphosphate IP 6 enhances the anti-proliferative effects of adriamycin and tamoxifen in breast cancer. It was recently recognized to possess multiple biological functions. Phytic acid and minerals: Myo -inositol is a parent compound of IP 6. Derivatives of phosphatidylinositol transmit cellular signals in response to extracellular stimuli, and enzymes responsible for the phosphorylation and hydrolysis of these signaling lipids play an important role in a broad range of biological effects.

Effects of dietary phytic acid phytate on the incidence and growth rate of tumors promoted in Fisher rats by a magnesium supplement.

However, recent studies demonstrate that this antinutrient effect of IP 6 can be manifested only when large quantities of IP 6 are consumed in combination with a diet poor in oligoelements 60 — A long-term intake of IP 6 in food 60 inostiol, 61 or in a pure form 64 did not cause such a deficiency in humans. A rapid dual organ rat carcinogenesis bioassay inksitol evaluating the chemoprevention of breast and colon cancer. IP 6 inhibited the growth of all tested jnositol lines in a dose- and time-dependent manner.

Adapted from Shamsuddin et al. The inclusion of IP 6 plus inositol in our strategies inowitol prevention and treatment of cancer as well as other chronic diseases is warranted. IP 6 is a natural compound and an important dietary component.

The role of IP 6 among these inosigol signaling pathways and their cross-talk inoaitol regulation of cell functions needs to be addressed in the future. A striking anticancer action of IP 6 was demonstrated in different experimental models.

A novel anticancer function of inositol hexaphosphate IP 6 ; 4 also Ins P 6 and phytic acid has been shown both in vivo and in vitro 3 — 5. The difference in total number of tumors, tumor burden No. Different binding proteins for inositol polyphosphates have been isolated, indicating inisitol importance for the cellular functions 12 such as effects on ion channels and protein trafficking 1314endocytosis 15exocytosis 16and efficient export of mRNA from the nucleus to the cell How can exogenously administered Inosito, 6 affect tumor growth?


Only myo -inositol hexaphosphate has been found in plants; neo – chiro – and scyllo inositoll hexaphosphates have been isolated from soil 7. A striking anticancer effect of IP6 was demonstrated in different experimental models. A potential hypocholesterolemic effect of IP 6 may be very significant in the clinical management of hyperlipidemia and diabetes 7576 However, in striking contrast to taxol, used as a control, IP 6 did not affect the ability of normal cells peripheral blood mononuclear cells and T-cell colony-forming inositoo to form colonies in a semisolid methylcellulose medium.

We found that inositol alone or in combination with IP 6 inositlo prevent the formation and incidence of several cancers in experimental animals: Many tumors produce large amounts insitol vascular endothelial growth factor, a cytokine that signals normal blood vessels to grow.

Recently, inositol phospholipids in the plasma membrane have received much attention because of their biological significance for signal transduction systems.

Antiproliferative effect inositol hexaphosphate IP 6 in breast cancer cells is mediated by increase in p27 and decrease in Rb protein phosphorylation. In addition to reducing cell proliferation, IP6 increases differentiation of malignant cells, often resulting in a reversion to normal phenotype. Inositol hexaphosphate IP6 is a naturally occurring polyphosphorylated carbohydrate that is present in substantial amounts in almost all plant and mammalian cells.

IP 6 can also adversely affect angiogenesis as antagonist of fibroblast growth factor 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. The most important expectation of a good anticancer agent is for it to only affect malignant cells and not affect normal cells and tissues. Additionally, we showed that inositol potentiates both the antiproliferative and antineoplastic effects of IP 6 in vivo 3 — 5193951 ,
