Article Abstract

Glutathione peroxidase 1 (Gpx1) and peroxiredoxin 2 (Prdx2) belong to the thiol peroxidase family of antioxidants, and have been studied for their antioxidant functions and roles in cancers. However, the physiological significance of Gpx1 and Prdx2 during vertebrate embryogenesis are lacking. Currently, we investigated the functional roles of Gpx1 and Prdx2 during vertebrate embryogenesis using as a vertebrate model. Our investigations revealed the zygotic nature of having its localization in the eye region of developing embryos, whereas exhibited a maternal nature and were localized in embryonic ventral blood islands. Furthermore, the -morphants exhibited malformed eyes with incompletely detached lenses. However, the depletion of has not established its involvement with embryogenesis. A molecular analysis of -depleted embryos revealed the perturbed expression of a -lens-specific marker and also exhibited reactive oxygen species (ROS) accumulation in the eye regions of -morphants. Additionally, transcriptomics analysis of -knockout embryos demonstrated the involvement of Wnt, cadherin, and integrin signaling pathways in the development of malformed eyes. Conclusively, our findings indicate the association of with a complex network of embryonic developmental pathways and ROS responses, but detailed investigation is a prerequisite in order to pinpoint the mechanistic details of these interactions.

Unraveling the multifaceted roles of peroxiredoxins in sickle cell anemia: implications in redox and inflammation adaptations.

Ann Hematol

Sickle cell anemia (SCA) presents a complex interplay of factors, with the production of high levels of reactive oxygen species (ROS) and the chronic inflammatory process leading to chronic oxidative stress. In this context, efficient action of antioxidant systems becomes crucial, with particular emphasis on peroxiredoxins (PRDXs) due to their abundance and vital roles. Our primary objective was to establish associations between gene and protein expression of PRDXs 1, 2, and 6, as well as their reducers TRX1, TRXR1, and SRX1, with the characteristic hyperoxidative status observed in SCA patients.

Abstract: Reactive oxygen species (ROS) are a by-product of the activity of cytochrome P450 steroidogenic enzymes. Antioxidant enzymes protect against ROS damage. To identify if any particular antioxidant enzyme is used to protect against ROS produced by granulosa cells as follicles enlarge and produce oestradiol, we measured in the bovine granulosa cells the expression of two steroidogenic enzymes (CYP11A1, CYP19A1), important for progesterone and oestradiol production.

Reticulocyte Antioxidant Enzymes mRNA Levels versus Reticulocyte Maturity Indices in Hereditary Spherocytosis, β-Thalassemia and Sickle Cell Disease.

Int J Mol Sci

The antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and peroxiredoxin 2 (Prx2) are particularly important in erythroid cells. Reticulocytes and other erythroid precursors may adapt their biosynthetic mechanisms to cell defects or to changes in the bone marrow environment. Our aim was to perform a comparative study of the mRNA levels of and in reticulocytes from healthy individuals and from patients with hereditary spherocytosis (HS), sickle cell disease (SCD) and β-thalassemia (β-thal), and to study the association between their transcript levels and the reticulocyte maturity indices.

Although bisphenol S (BPS), as a bisphenol A (BPA) substitute, has been widely used in the commodity, it is embryotoxic in recent experiments. Nowadays, it remains unclear how BPS affects preimplantation embryos. Here, my team investigated the effects of BPS on preimplantation embryos and the possible molecular mechanisms in mice.

Physiology and Proteomic Basis of Lung Adaptation to High-Altitude Hypoxia in Tibetan Sheep.

Animals (Basel)

August 2022

Gansu Key Laboratory of Herbivorous Animal Biotechnology, Faculty of Animal Science and Technology, Gansu Agricultural University, Lanzhou 730070, China.

The Tibetan sheep is an indigenous animal of the Tibetan plateau, and after a long period of adaptation have adapted to high-altitude hypoxia. Many physiological changes occur in Tibetan sheep as they adapt to high-altitude hypoxia, especially in the lungs. To reveal the physiological changes and their molecular mechanisms in the lungs of Tibetan sheep during adaptation to high altitudes, we selected Tibetan sheep from three altitudes (2500 m, 3500 m, and 4500 m) and measured blood-gas indicators, observed lung structures, and compared lung proteome changes.
