1 Inositol hexaphosphate inhibits constitutive activation of NF- kappa B in androgen-independent human prostate carcinoma DU145 cells. Phytic Acid nuclear factor kappa B subunit 1 Homo sapiens
2 Since transcription factor NF-kappa B is constitutively active in advanced and androgen-independent human PCA DU145 cells, here we assessed whether IP6 inhibits this constitutively active NF-kappa B and associated upstream effectors and whether such an affect of IP6 has biological relevance in causing inhibition of proliferation and induction of apoptosis in DU145 cells. Phytic Acid nuclear factor kappa B subunit 1 Homo sapiens
3 RESULTS: Treatment of cells with 1 and 2 mM doses of IP6 resulted in a strong inhibition of NF-kappa B activation, which was consistent with a decrease in nuclear levels of NF-kappa B sub-unit proteins p65 and p50. Phytic Acid nuclear factor kappa B subunit 1 Homo sapiens
4 RESULTS: Treatment of cells with 1 and 2 mM doses of IP6 resulted in a strong inhibition of NF-kappa B activation, which was consistent with a decrease in nuclear levels of NF-kappa B sub-unit proteins p65 and p50. Phytic Acid nuclear factor kappa B subunit 1 Homo sapiens
5 RESULTS: Treatment of cells with 1 and 2 mM doses of IP6 resulted in a strong inhibition of NF-kappa B activation, which was consistent with a decrease in nuclear levels of NF-kappa B sub-unit proteins p65 and p50. Phytic Acid nuclear factor kappa B subunit 1 Homo sapiens
6 CONCLUSION: Our results suggest that IP6 could be a potent dietary agent in controlling the growth of advanced PCA cells and inducing their apoptotic death, in part, by its inhibitory effect on constitutively active NF-kappa B signaling pathway. Phytic Acid nuclear factor kappa B subunit 1 Homo sapiens
