DNA polymerase beta mediates protection of mammalian cells against ganciclovir-induced cytotoxicity and DNA breakage.
The efficacy of suicide herpes simplex virus-1 thymidine kinase (HSVtk)/ganciclovir (GCV) gene therapy is often limited by intrinsic resistance of tumor cells. Here we show that repair of GCV incorporated in DNA is a factor involved in GCV resistance. A protective role of DNA repair in GCV-induced cell killing is supported by the following findings: (a) GCV-exposed Chinese hamster ovary-HSVtk c...
متن کاملAntioxidant properties of pyrrolidine dithiocarbamate and its protection against Cr(VI)-induced DNA strand breakage.
Pyrrolidine dithiocarbamate (PDTC) is considered an antioxidant and is frequently used to study the role of free radical reactions in various biological processes and against free radical-induced cellular injuries. However, its antioxidant properties are not characterized. In this study, electron spin resonance (ESR) was used to investigate the antioxidant potential of PDTC with hydroxyl radica...
متن کاملAmifostine protection against mitomycin-induced chromosomal breakage in fanconi anaemia lymphocytes.
Fanconi anaemia (FA) is a rare genetic chromosomal instability syndrome caused by impairment of DNA repair and reactive oxygen species (ROS) imbalance. This disease is also related to bone marrow failure and cancer. Treatment of these complications with radiation and alkylating agents may enhance chromosomal breakage. We have evaluated the effect of amifostine (AMF) on basal and mitomycin C (MM...
متن کاملProtective effect of silymarin against chemical-induced cardiotoxicity
Cardiac disorders remain one of the most important causes of death in the world. Oxidative stress has been suggested as one of the molecular mechanisms involved in drug-induced cardiac toxicity. Recently, several natural products have been utilized in different studies with the aim to protect the progression of oxidative stress-induced cardiac disorders. There is a large body of evidence that a...
متن کاملSaffron Protection against Bleomycin-Induced Pulmonary Fibrosis in Rats
Background: Bleomycin-induced lung fibrosis has been accepted as an animal model for fibrosis in rats. The aim of this study was to evaluate the effects of saffron aqueous extract on this disorder paving the way for more investigation in treating idiopathic pulmonary fibrosis in human. Methods: Male Wistar rats (250–300 gr) were instilled a single dose of bleomycin (5 mg/kg) via in...
