Abstract

Phytate or myo-inositol hexakisphosphates (IP6) is widely distributed in plants like rice brans. The production of myo-inositol phosphate intermediates has received much attention due to the remarkable potential health benefits offered by the compounds. In this study, the cytotoxicity of the partially purified myo-inositol phosphate fractions and commercial IP1 and IP6 were investigated against MCF-7 breast cancer cell lines. The study showed that the commercial standard IP1 and IP6 showed good inhibition towards the MCF-7 cell line. The MCF-7 cells growth was inhibited in minimum concentration of myo-inositol phosphates (<1000 µg/ml). However, no inhibition observed on the MCF-7 cell line by the myo-inositol phosphates fractions partially purified from rice bran at concentration <1000 ?g/ml. The inhibition of MCF-7 was only observed at concentration more than 30 mg/ml with more than 40% cells were inhibited. This indicates that the partially purified rice bran myo-inositol phosphates degraded by ASUIA279 phytase on MCF-7 breast cancer cells exhibit positive results towards the inhibition of cancer cells growth at relatively high concentration..

ABSTRAK: Fitat atau myo-inositol hexakisphosphate (IP6) dikenali umum teragih di dalam tumbuhan seperti dedak padi. Penghasilan perantaraan fosfat myo-inositol mendapat perhatian memandangkan ia berpotensi tinggi dalam kesihatan. Dalam kajian ini, kesitotoksikan sebahagian daripada fosfat myo-inositol separa tulen, IP1 komersil dan IP6 komersil dikaji terhadap produk yang berupa sel kekal (cell lines) kanser payu dara MCF-7. Tumbesaran sel MCF-7 direncatkan dalam pekatan minima fosfat myo-inositol (<1000 μg/ml). Tetapi, tidak ada perencatan dilihat terhadap sel kekal MCF-7 oleh sebahagian fosfat myo-inositol separa tulen daripada dedak padi pada kepekatan <1000 mg/ml. Perencatan MCF-7 hanya dilihat pada kepekatan lebih daripada 30 mg/ml dengan lebih daripada 40% sel terencat. Ini menunjukkan bahawa fosfat myo-inositol daripada dedak padi separa tulen terdegradasi oleh fitat ASUIA279 terhadap sel kanser MCF-7 dimana ia menunjukkan keputusan positif terhadap perencatan tumbesaran sel kanser pada kepekatan tinggi.
