Abstract:
Peroxiredoxins (PRDXs) are members of a highly conserved peroxidase family and maintain intracellular reactive oxygen species (ROS) homeostasis. The family members are expressed in most organisms and involved in various biological processes, such as cellular protection against ROS, inflammation, carcinogenesis, atherosclerosis, heart diseases, and metabolism. In mammals, six PRDX members have been identified and are subdivided into three subfamilies: typical 2-Cys (PRDX1, PRDX2, PRDX3, and PRDX4), atypical 2-Cys (PRDX5), and 1-Cys (PRDX6) subfamilies. Knockout mouse models of PRDXs have been d

Abstract Introduction: Uterine corpus endometrial carcinoma (UCEC) is one of the most commonly diagnosed cancers in women in the United States, where the death rate continues to climb by 1.9% every year due to poor prognostic and therapeutic methodologies. Recently, altered expression patterns of peroxiredoxins (PRDX) (1-6), a family of antioxidant enzymes comprised of six known isoforms, has been connected to overall outcome in many cancers. While recent studies have begun to unravel the potential of PRDXs as prognostic biomarkers in other cancers, PRDX expression patterns and their use as pr

Abstract:
The peroxiredoxin (PRDX) gene family has been reported to participate in regulating occurrence and development of cancerous diseases, but its exact prognostic values in gastric cancer (GC) remain largely elusive. In the current research, we evaluated the prognostic value in predicting overall survival (OS) of each individual PRDX mRNA expression based on patients’ cohorts from the Kaplan–Meier (KM) plotter database, which contains clinical information and gene expression data obtained from a total of 876 GC patients. Our results revealed that mRNA expressions of PRDX1, PRDX2, PRDX3, and PRDX4

Abstract Punicic Acid is an omega-5 long chain saturated fatty acid found in abundance in the oil of pomegranate seeds. While already known to provide various health benefits from a dietary perspective, punicic acid (PA) has also been shown to be an anti-proliferation agent in various cancer cell lines such as colorectal cancer and breast cancer. In this study, we examined the effects of PA on the MCF-7 breast cancer cell line as compared to the non-cancerous MCF-10A breast epithelial cell line. We found that PA induces dose-dependent cytotoxicity on both lines, with higher cytotoxicity in MCF

Abstract:
Peroxiredoxin 6 (Prdx6) is a novel peroxidase enzyme belonging to the Prdx family, which in mammals contains five more peroxiredoxins (Prdx1–Prdx5). Like glutathione peroxidase (GSHPx) and catalase, Prdx6 possesses H2O2-scavenging activities, and, like the former, it also removes hydroperoxides. Since significant amounts of catalase and GSHPx are present in the heart contributing toward the attenuation of H2O2 and hydroperoxides formed during ischemia-reperfusion injury and thereby providing cardioprotection, we asked whether Prdx6 also has any role in this process.

Hydrogen peroxide, a Prdx substrate, was used as the model oxidant pertinent to redox signaling during health and to injury at higher concentrations. Rat hearts were aerobically perfused with a broad concentration range of hydrogen peroxide by the Langendorff method, homogenized, and analyzed by immunoblotting. Hea

Moreover, studies on Prdx6−/− mice revealed the essential role of PRDX6 in the viability, motility, and fertility competence of spermatozoa. Although PRDXs are abundant in the testis and spermatozoa, their potential role at different phases of spermatogenesis and in perinatal germ cells is unknown. Here, we

The oxidative stress modulation is tightly related with the physiopathology of various hematologic diseases and can cause cell death, apoptosis and necrosis.

Ferroptosis is a form of non-apoptotic cell death induced by the iron-dependent accumulation of lipid hydroperoxides. It has been extensively studied due to its involvement in various pathological conditions, such as cancer, neurodegenerative diseases, and ischaemia–reperfusion injury. Selenoprotein glutathione peroxidase 4 (GPX4) is a critical suppressor of ferroptosis that detoxifies lipid hydroperoxides into nontoxic lipid alcohols via a catalytic selenocysteine (Sec) residue.
