Increased manganese superoxide dismutase expression or treatment with manganese porphyrin potentiates dexamethasone-induced apoptosis in lymphoma cells.
Glucocorticoid-induced apoptosis is exploited for the treatment of hematologic malignancies. Innate and acquired resistance limits treatment efficacy; however, resistance mechanisms are not well understood. Previously, using WEHI7.2 murine thymic lymphoma cells, we found that increasing the resistance to hydrogen peroxide (H(2)O(2)) by catalase transfection or selection for H(2)O(2) resistance ...

2 Introduction 3 Phylogenetic distribution and subcellular localization 3 Kinetics and mechanism 3 Molecular and chemical structure 5 Biological significance 8 Summary 9 References 10 Abstract Manganese superoxide dismutase (MnSOD) is the primary antioxidant enzyme that protects cells from oxidative stress by catalyzing dismutation of superoxide (O2 ) to hydrogen peroxide and oxygen in the mito...
متن کاملProliferation, apoptosis, and manganese superoxide dismutase in malignant mesothelioma.
Proliferation and apoptotic indices of tumour cells may have important prognostic significance. Manganese superoxide dismutase (MnSOD), an important anti-oxidant enzyme, has been shown to decrease proliferation of malignant cells transfected with the MnSOD gene. The aim of the present study was to investigate the indices of cell proliferation and apoptosis and their prognostic significance in h...
متن کاملIncreased manganese superoxide dismutase expression suppresses the malignant phenotype of human melanoma cells.
Introduction of a normal human chromosome 6 into human melanoma cell lines results in suppression of tumorigenicity. This suggests that a gene(s) on chromosome 6 controls the malignant phenotype of human melanoma. Because antioxidants can suppress the tumor-promotion phase of carcinogenesis, and because the antioxidant enzyme manganese superoxide dismutase (MnSOD) has been localized to a region...
متن کاملmiR-23a Regulates Cardiomyocyte Apoptosis by Targeting Manganese Superoxide Dismutase
Cardiomyocyte apoptosis is initiated by various cellular insults and accumulated cardiomyocyte apoptosis leads to the pathogenesis of heart failure. Excessive reactive oxygen species (ROS) provoke apoptotic cascades. Manganese superoxide dismutase (MnSOD) is an important antioxidant enzyme that converts cellular ROS into harmless products. In this study, we demonstrate that MnSOD is down-regula...
