ABSTRACT. Inositol hexaphosphate (IP6) is a naturally occurring polyphosphorylated carbohydrate that is present in substantial amounts in almost all plant and. 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.

They also showed that the levels of IP 6 and its less phosphorylated forms fluctuate depending on the intake of IP 6. Almost 15 y ago, Inoditol et al. A substantial amount of radioactivity Exogenously administered IP 6 is rapidly taken into the cells and dephosphorylated to lower-phosphate inositol phosphates, which further interfere with signal transduction pathways and cell cycle arrest.

IP 6 induces G 1 phase arrest and a significant decrease of the S phase of human breast 6869colon 69and prostate 34 cancer cell lines. Effects of inositol hexaphosphate IP 6 on human normal and leukaemic hematopoietic cells. 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 inosihol effects. IP 6 inhibited the growth and differentiation of endothelial cells 6672 and inhibited the secretion of vascular endothelial growth factor from malignant cells 2766 Chalcones, myo-inositol and other novel inhibitors of pulmonary carcinogenesis.
Value of IP 6 as a therapeutic and preventive agent for cancer. Antitumor effect of inositol hexaphosphate IP 6 in vitro.
Myo -inositol is a parent compound of IP 6. These data indicate that IP 6 can reach and concentrate at cellular targets. Inositol hexaphosphate InsP 6: It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide.
A high oat-bran intakes does not impair zinc absorption inositoo human when added to a low-fiber ibositol protein-based diet. Thus, the combination of IP 6 and inositol was significantly better in different cancers than was either one alone. How can exogenously administered IP 6 affect tumor growth? Lp6 of dietary sodium phytate on the hepatic and serum levels of lipids and on the hepatic activities of NADH-generating enzymes in rats fed on sucrose.
Because it is abundantly present in regular diet, efficiently absorbed from the gastrointestinal tract, and safe, IP6 holds great promise in our strategies for the prevention and treatment of cancer. One patient with liver metastasis refused chemotherapy after the first treatment, and she was treated only with IP 6 plus inositol; her control ultrasound and abdominal computed tomography scan 14 mo after surgery showed a significantly reduced growth rate.
Inosiyol were able to obtain comparable or even stronger tumor inhibition with much lower concentrations of IP 6 when it was given in drinking water. Lowering of serum cholesterol and triglycerides and modulations by dietary phytate.
This activity seems to be closely related to its unique structure. Malignant and normal cells are known to have a knositol metabolism, growth rate, expression of receptors, etc. 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.
Protection against cancer by dietary IP6 and inositol.
It was recently recognized to possess multiple biological functions. 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 Recently IP 6 has received much attention for its role in cancer prevention and control of experimental tumor growth, progression, and metastasis.
Phytic acid and minerals: Norman and Ritva R. Tumors depend on the formation of new blood vessels to inosiyol their growth and metastasis.

Recently, inositol phospholipids in the plasma membrane have received much attention because of their biological significance for signal transduction systems. 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.
That the extracellularly applied IP 6 enters the cell and that this intracellular delivery is followed by a dephosphorylation of IP 6 was recently confirmed by Ferry et al. Modulatory influence of arecoline on the phytic ipp6 hepatic biotransformation system enzymes, sulfhydryl content and il6 peroxidation in a murine system. IP 6 can also adversely affect angiogenesis as antagonist of fibroblast growth factor An antagonist of fibroblast growth factor receptor binding and activity.
Cancer inhibition by inositol hexaphosphate (IP6) and inositol: from laboratory to clinic.
Analyzing absorption, intracellular distribution, and metabolism of IP 6 in HT human colon carcinoma inositool cells of hematopoietic lineage K, human erythroleukemia and YAC-1, mouse lymphoma cellswe found that IP 6 is rapidly taken up by mechanisms probably involving pinocytosis or receptor-mediated endocytosis, transported intracellularly, and dephosphorylated into inositol phosphates with fewer phosphate groups It was also hypothesized that the addition up6 inositol, a precursor of inositol phosphates and also a natural carbohydrate, to IP 6 may enhance the anticancer function of IP 6 18 — Many potential beneficial actions of IP 6 have been described.
Adapted from Shamsuddin et al. As hypothesized, it was demonstrated that IP 6 is a broad-spectrum antineoplastic niositol, affecting different cells and tissue systems.
IP 6a natural compound with virtually no toxicity, can satisfy this special and very important requirement for cancer prevention. It is now recognized that subsequent to PIP 2 hydrolysis a cascade of inositol phosphate metabolites are formed and that these multiple isomers show a complex pattern of interconversion 8 — Inositol hexaphosphate IP 6 is a naturally occurring polyphosphorylated carbohydrate, abundantly present in many plant sources and inosutol certain high-fiber diets, such as cereals and legumes.
IP 6 also inhibited the growth of mesenchymal tumors, murine fibrosarcoma 39and human rhabdomyosarcoma
