Glutathione peroxidase 3 (GPX3) is a member of the glutathione peroxidase family of selenoproteins and is one of the key defensive enzymes against oxidative damages to host cells. Downregulation of GPX3 due to its promoter hypermethylation has been documented in several different types of cancer, indicating that GPX3 functions as a possible tumor suppressor. In the present study, we showed that GPX3 is also significantly downregulated in cervical cancer tissues compared to normal cervical… 
Hypermethylation and downregulation of glutathione peroxidase 3 are related to pathogenesis of melanoma.
TLDR
Depletion of GPX3 was found to increase the proliferative ability, motility, and invasiveness of melanoma cells and negative expression of GPx3 was related to poor prognosis in melanoma patients.
Distinct prognostic values of mRNA expression of glutathione peroxidases in non-small cell lung cancer
TLDR
The current findings of prognostic values of individual mRNA expression of GPxs in NSCLC patients indicate some GPxs may have prognostic value in NSClC patients, and this needs further study.
Reduced Expression of GPX3 in Breast Cancer Patients in Correlation with Clinical Significance
TLDR
The results suggested that GPX3 plays a role in breast carcinogenesis, and might serve as a prognostic biomarker in breast cancer patients.
GPX2 suppression of H2O2 stress regulates cervical cancer metastasis and apoptosis via activation of the β-catenin-WNT pathway
TLDR
GPX2 was highly expressed in cervical cancer tissues compared to normal individuals and promoted the proliferation and metastasis of cervical cancer by affecting oxidative stress, and this promotion correlated with the activation of EMT and WNT/β-catenin signaling in vitro.
GPX3 suppresses tumor migration and invasion via the FAK/AKT pathway in esophageal squamous cell carcinoma.
TLDR
It is found that the methylation rate in advanced cancers was significantly higher than that in early stage cancers by a methylation-specific polymerase chain reaction, and GPX3 has the potential as a novel biomarker in the diagnosis of ESCC.

5-Aza-2’-deoxycytidine inhibits proliferation and induces apoptosis in oral cancer cells by enhancing glutathione peroxidase-3 expression
TLDR
The results suggest that 5-Aza-Cd suppressed proliferation and accelerated apoptosis in oral cancer cells by inhibiting demethylation and thereby promoting GPX3 expression.
Extracellular Glutathione Peroxidase GPx3 and Its Role in Cancer
TLDR
Glutathione peroxidase 3 has a dichotomous role in different tumor types, acting as both a tumor suppressor and pro-survival protein, and how GPx3 might be targeted for therapeutic intervention is examined.

Hypermethylation and loss of expression of glutathione peroxidase-3 in Barrett's tumorigenesis.
TLDR
The observed high frequency of promoter hypermethylation and progressive loss of GPx3 expression in BA and its associated lesions, together with its known function as a potent antioxidant, suggest that epigenetic inactivation and regulation of glutathione pathway may be critical in the development and progression of BE.
An 8-gene signature, including methylated and down-regulated glutathione peroxidase 3, of gastric cancer.
TLDR
This 8-gene set can predict the normal and cancer status of gastric tissues with more than 96% accuracy in a totally independent microarray dataset and shows a correct identification of 8 genes as gastric cancer biomarkers.
Identification of GPX3 Epigenetically Silenced by CpG Methylation in Human Esophageal Squamous Cell Carcinoma
TLDR
GPX3 is downregulated through promoter hypermethylation in ESCC, which may be a potential biomarker of ESCC.
Glutathione peroxidase 3 is a candidate mechanism of anticancer drug resistance of ovarian clear cell adenocarcinoma.
TLDR
Six genes including the glutathione peroxidase 3 (GPX3) gene were identified to be a gene highly expressed in clear cell adenocarcinoma by DNA microarray analysis, which indicates GPX3 may be a candidate gene associated with the low cisplatin sensitivity of clear cell adsorption to platinum drugs.
Functional epigenomics identifies genes frequently silenced in prostate cancer.
TLDR
Six genes were silenced by CpG methylation in the majority of five analyzed prostate cancer cell lines, although they displayed robust mRNA expression in normal prostate epithelial cells obtained from four different donors.

Glutathione peroxidases and redox-regulated transcription factors
TLDR
Analysis of the selenoproteome identified cGPx, PHGPx and GI-GPx have distinct roles, particularly in cellular defence mechanisms, and indicates that nature has not created redundant GPxs just to detoxify hydroperoxides.
