Abstract

BACKGROUND: Prospective, randomized, pilot clinical study was conducted to evaluate the beneficial effects of inositol hexaphosphate (IP6) + Inositol in breast cancer patients treated with adjuvant therapy. PATIENTS AND METHODS: Patients with invasive ductal breast cancer where polychemotherapy was indicated were monitored in the period from 2005-2007. Fourteen patients in the same stage of ductal invasive breast cancer were involved in the study, divided in two randomized groups. One group was subjected to take IP6 + Inositol while the other group was taking placebo. In both groups of patients the same laboratory parameters were monitored. When the treatment was finished, all patients have filled questionnaires QLQ C30 and QLQ-BR23 to determine the quality of life. RESULTS: Patients receiving chemotherapy, along with IP6 + Inositol did not have cytopenia, drop in leukocyte and platelet counts. Red blood cell counts and tumor markers were unaltered in both groups. However, patients who took IP6 + Inositol had significantly better quality of life (p = 0.05) and functional status (p = 0.0003) and were able to perform their daily activities. CONCLUSION: IP6 + Inositol as an adjunctive therapy is valuable help in ameliorating the side effects and preserving quality of life among the patients treated with chemotherapy.

Abstract

OBJECTIVES/HYPOTHESIS: Nuclear factor (NF)-kappaB is an early response gene that has been associated with head and neck squamous cell cancer (HNSCC) progression. NF-kappaB activation is induced by some chemotherapy agents, including paclitaxel. The activation of this gene can be correlated with apoptosis resistance. Inositol hexaphosphate (IP6) is a naturally occurring polyphosphorylated carbohydrate. NF-kappaB levels were evaluated in oral cavity HNSCC lines after treatment with paclitaxel and IP6, alone and in combination. Resulting levels of cell death and apoptosis were assessed, and conclusions are drawn regarding a possible synergistic relationship between paclitaxel and IP6. METHODS: NF-kappaB activation in cancer cells treated with paclitaxel and IP6, alone and in combination, was measured by transient transfection, and results were interpreted by luminometry. Cell proliferation of treated cells was measured by MTT assay. Cell viability and apoptosis of cancer cells treated with paclitaxel and IP6 combinations were quantitated by trypan blue staining and Caspase-Glo 3/7 assay, respectively. RESULTS: IP6 was observed to significantly downregulate NF-kappaB activation in both NA and CA-9-22 oral cavity HNSCC cell lines. Paclitaxel treatments caused increased NF-kappaB activation in the same cell lines. IP6 was observed to mitigate paclitaxel-induced NF-kappaB activation in the CA-9-22 cell line. IP6, when combined with paclitaxel, reduces CA-9-22 cell proliferation, increases cell death, and increases apoptosis, when compared with treatment with paclitaxel alone. CONCLUSIONS: IP6 reduces paclitaxel induced NF-kappaB activation and increases paclitaxel-mediated cell killing and apoptosis. As a well-tolerated and safe supplement, IP6 deserves further study in the treatment of oral cavity squamous cell carcinoma.

Abstract





INTRODUCTION: Pancreatic cancer is an extremely virulent form of cancer with few effective treatments. We hypothesized that, alone and in combination, IP6 and catechin would be effective against pancreatic cancer. MATERIALS AND METHODS: Pancreatic (PANC-1 and MIAPACA) cancer cell lines were cultured and treated with IP6 (0.8 mM/well), catechin (100 microM/well), and the combination of the two. Cell viability was measured by 3-(4,5-dimethylthiazol-2-y1)-2,5-diphenyltetrazolium bromide (MTT) at 24, 48, and 72 h. Vascular endothelial growth factor (VEGF) was measured in the cell supernatants by ELISA. Apoptosis was evaluated by Annexin V-fluorescein isothiocyanate (FITC). RESULTS: Catechin and inositol hexaphosphate (IP6), two naturally occurring molecules found in green tea and high-fiber foods, respectively, are compounds that have been shown to demonstrate anti-proliferative effects when administered as single therapeutic agents against a number of cancers.The combination of catechin and IP6 significantly inhibited proliferation in the PANC-1 cell line at 24, 48, and 72 h compared to single agents (P < 0.001). Growth of the MIAPACA cell line was inhibited (P < 0.01) by each agent alone, but additive inhibitory effects were not seen. An increase in early apoptosis was attributed to catechin therapy in both cell lines (P < 0.01). The combination of these agents also increased early apoptotic activity when compared to the control (P < 0.001). IP6 reduced VEGF in both cell lines (P < 0.01). In combination, catechin and IP6 amplified VEGF reduction compared to each agent in MIAPACA and control (P < 0.002). CONCLUSIONS: These results, combined with the prevalence of these compounds in safe, naturally occurring foods, make catechin and IP6 attractive therapies for treatment, and possibly in preventative trials, of pancreatic cancer.
