چکیده

This study used Western blot analysis to measure the expression of superoxide dismutases (Mn-SOD and Cu/Zn-SOD) in breast cancer tissues from 57 patients. Mn-SOD expression in the breast cancer tissues averaged 1.5-fold higher than in the adjacent tumor-free tissues (p <0.05). There was no significant difference in Cu/Zn-SOD expression between neoplastic and tumor-free breast tissues. This study shows a significant increase of Mn-SOD expression in breast cancer tissues. The authors speculate that up-regulation of Mn-SOD expression induced by oxidative stress or local inflammation may contribute a selective growth advantage to tumor cells compared to their normal counterparts.

Differential Expression of Mitochondrial Manganese Superoxide Dismutase (SOD) in Triticum aestivum Exposed to Silver Nitrate and Silver Nanoparticles

Background: The increasing use of nanoparticles (NPs) may have negative impacts on both organisms andthe environment. Objectives: The differential expression of mitochondrial manganese superoxide dismutase (MnSOD) gene in wheat in response to silver nitrate nanoparticles (AgNPs) and AgNO3 was investigated. Materials and Methods: A quantita...

Association between manganese superoxide dismutase (MnSOD) gene polymorphism and breast cancer risk.

Superoxide dismutases play a key role in the detoxification of superoxide radicals and thus protect cells from damage induced by free radicals. Within mitochondria manganese superoxide dismutase (MnSOD) provides a major defence against oxidative damage by reactive oxygen species. Polymorphism in the mitochondrial targeting sequence of MnSOD has recently been associated with risk of breast cance...

Maspin gene expression in tumor suppression induced by overexpressing manganese-containing superoxide dismutase cDNA in human breast cancer cells.

We have reported the tumor suppressive effects of manganese-containing superoxide dismutase (MnSOD) in human breast cancer cells. In order to understand the molecular mechanism of this anti-tumor effect, we asked whether tumor suppressor gene(s), especially the ones inhibiting tumor invasion and motility, are involved in MnSOD-induced tumor suppression. Maspin is one of the serpin family of pro...

A mitochondrial target sequence polymorphism in manganese superoxide dismutase predicts inferior survival in breast cancer patients treated with cyclophosphamide.

PURPOSE Manganese superoxide dismutase protects against oxidative damage and modulates the efficacy of chemotherapeutic drugs. A functional single-nucleotide polymorphism in codon 16 of SOD2 (rs4880), which encodes manganese superoxide dismutase, results in a substitution of valine by alanine (Val16Ala). We hypothesized that this single-nucleotide polymorphism affects breast cancer survival of ...

Manganese superoxide dismutase in breast cancer: from molecular mechanisms of gene regulation to biological and clinical significance.

Breast cancer is one of the most common malignancies of all cancers in women worldwide. Many difficulties reside in the prediction of tumor metastatic progression because of the lack of sufficiently reliable predictive biological markers, and this is a permanent preoccupation for clinicians. Manganese superoxide dismutase (MnSOD) may represent a rational candidate as a predictive biomarker of b...
