Is dynamic thiol/disulfide homeostasis associated with the prognosis of myelodysplastic syndrome?

Introduction Myelodysplastic syndrome (MDS) is a heterogeneous clonal hemopoietic stem cell disease characterized by various levels of cytopenias and abnormal myeloid cell differentiation and maturation in addition to acute leukemia transformation risk. Although cytopenia (anemia, neutropenia, and thrombocytopenia) is seen in MDS patients, the bone marrow (BM) is often hypercellular and dysplastic, and the functions of the blood cells in circulation are disrupted. Although MDS could develop de novo, it could also develop secondary to previously administered

Genes encoding proteins regulating fatty acid metabolism and cellular response to lipids are differentially expressed in porcine luminal epithelium during long-term culture

creating a barrier on the surface of the epithelium and are also involved in intracellular signal transmission [ 19 ]. MUC1 is considered to be one of the epithelial markers of porcine embryo pluripotent cells [ 20 ]. A decrease in MUC1 gene expression in the endometrium is responsible for a decrease in the rate of embryo implantation in humans [ 21 ]. The KITLG gene (KIT ligand), exhibiting increased expression in the OEC in vitro culture, is related to the development of, among others, stem cell or germ cell populationin reproductive organs, and its mutations

Biochemical properties of cofactor and coenzyme metabolism in porcine oviductal epithelial cells – a microarray study

-regulated gene was P2RX7 which generates a plasma membrane receptor for extracellular ATP. P2RX7 is expressed at a high level by immune and tumor cells; however recent studies have shown its presence in an increasing number of different cells lineages, including stem, neural, bone, endothelial, muscle, and skin cells [ 17 ]. P2RX7 was revealed in the oviductal epthelium, and is a cation-selective plasma membrane channel that undergoes, when over-activated, a channel-to-pore transition responsible for a reversible permeabilization of the plasma membrane to low molecular
