Re: Davis et al., "Timing of captopril administration determines radiation protection or radiation sensitization in a murine model of total body irradiation".

OBJECTIVE Angiotensin II (Ang II), a potent vasoconstrictor, affects the growth and development of hematopoietic cells. Mixed findings have been reported for the effects of angiotensin-converting enzyme (ACE) inhibitors on radiation-induced injury to the hematopoietic system. We investigated the consequences of different regimens of the ACE inhibitor captopril on radiation-induced hematopoietic...

Radio-protective effect of hydrogen rich water combined with amifostine in mice

Background:  Hydrogen has been demonstrated can selectively reduce the hydroxyl, which is the main cause of ionizing radiation-induced damage. Amifostine (AM) is the only radioprotective drug approved by the U.S. Food and Drug Administration for use in radiotherapy. The purpose of the present study was to investigate the combined radio-protective effect of hydrogen rich water (HRW) and AM....

Captopril modulates hypoxia-inducible factors and erythropoietin responses in a murine model of total body irradiation.

OBJECTIVE Our laboratory reported that the angiotensin converting enzyme inhibitor captopril improves erythroid recovery from total body irradiation (TBI) in mice when administered after irradiation. However, captopril administered before TBI attenuates erythroid recovery. Here we investigate captopril and radiation regulation of erythropoietin (EPO) and thrombopoietin (TPO), key effectors of e...

Impact of Prolonged Fraction Delivery Time Modelling Stereotactic Body Radiation Therapy with High Dose Hypofractionation on the Killing of Cultured ACHN Renal Cell Carcinoma Cell Line

Introduction: Stereotactic body radiotherapy delivers hypofractionated irradiation with high dose per fraction through complex treatment techniques. The increased complexity leads to longer dose delivery times for each fraction. The purpose of this study is to investigate the impact of prolonged fraction delivery time with high-dose hypofractionation on the killing of cultured ACHN cells.Method...

Ameliorating effects of genestein: Study on mice liver glutathione and lipid peroxidation after irradiation

Background: Genistein is a soya isoflavone, which is found naturally in legumes, such as soybeans and chickpeas. Radiation–induced free radicals in turn impair the antioxidative defense mechanism, leading to an increased membrane lipid peroxidation that results in damage of the membrane bound enzyme and may lead to damage or death of cell. Hence, the lipid peroxidation is a good biomar...
