Phenylpropanoids in radioregulation: double edged sword.

Wanyeon Kim, Ki Moon Seong, and BuHyun Youn

Exp Mol Med 43(6):323-33 (2011) PMID 21483230

Radiotherapy, frequently used for treatment of solid tumors, carries two main obstacles including acquired radioresistance in cancer cells during radiotherapy and normal tissue injury. Phenylpropanoids, which are naturally occurring phytochemicals found in plants, have been identified as potential radiotherapeutic agents due to their anti-cancer activity and relatively safe levels of cytotoxicity. Various studies have proposed that these compounds could not only sensitize cancer cells to radiation resulting in inhibition of growth and cell death but also protect normal cells against radiation-induced damage. This review is intended to provide an overview of recent investigations on the usage of phenylpropanoids in combination with radiotherapy in cancer treatment.

    We demonstrate here that myricetin inhibits Akt activity to induce apoptosis in a low dose ('repairable dose') UVB-irradiated keratinocytes. Treatment of UVB-irradiated HaCaT cells with an apoptosis-inducing concentration of myricetin (20 microM) resulted in a decrease in phosphorylation of Akt lead...

    We have proven that the purified CaRad3 protein has a Fe-S cluster. We also revealed that CaRad3 protein has a helicase activity on a duplex DNA substrate. Furthermore, we showed that the CaRad3 protein purified from yeasts was N-glycosylated, and that this protein complemented the defects in both t...
