Abstract:
Environ 80% des cancers du poumon sont des carcinomes du poumon non à petites cellules (NSCLC). Les NSCLC posent un enjeu médical majeur en raison de leur forte incidence et du taux de mortalité qu’ils induisent. Ils sont généralement traités avec le cisplatine (CDDP), l'un des agents anticancéreux les plus largement utilisés aujourd'hui. Cependant, après plusieurs mois, des cellules cancéreuses résistantes à l'apoptose induite par le CDDP apparaissent et compromettent le succès de la chimiothérapie. Le CDDP est un composé pro-apoptotique qui se lie l'ADN nucléaire pour former des liaisons int

Abstract:
AbstractProtein disulfide isomerases (PDIs) family members are essential for proper folding of proteins entering the secretory pathway. Studies of these remarkable enzymes have shown that PDIs catalyze the oxidation, reduction and isomeration of disulfide bonds in the endoplasmic reticulum (ER). PDIs are found and conserved in a wide range of species and are ubiquitously expressed.In all eukaryotes, the ER redox potential must be tightly controlled since a large fraction of proteins within the cell require disulfide-bond formation. How PDIA1 maintains a balance between oxidation and reduction

1a,25-Dihydroxyvitamin D3 (1a,25(OH)2D3) is a major functional metabolic form of vitamin D. 1a,25(OH)2D3 has drawn increasing attention due to its functions in addition to maintaining calcium phosphate homeostasis. It directly regulates mineralization by osteoblasts, matrix production and remodeling by chondrocytes, and contraction of cardiomyocytes. 1a,25(OH)2D3 and its analogues have shown beneficial effects in treating multiple sclerosis, diabetes and various types of cancer.

Abstract:
Intro: Hypovitaminosis D (vitamin D deficiency) has been observed in ageing patients with brain calcification and loss of the vitamin D receptor leads to abnormal calcification of the basal ganglia and thalamus. We have found that vitamin D can reverse calcification of human osteosarcoma SaOs-2 cells in vitro, in apparent contrast to its known effects of increasing bone strength in patients with Rickets and Osteomalacia. Vitamin-D functions through binding to two Vitamin-D responsive proteins; the vitamin D receptor (VDR) and Protein Disulfide isomerase A3 (PDIA3). The aim of this project was

The vitamin D metabolite 1,25-dihydroxyvitamin D3 [1α,25(OH)2D3] plays an important role in the regulation of musculoskeletal growth and differentiation. 1α,25(OH)2D3 mediates its effects on cells, including chondrocytes and osteoblasts, through the classical nuclear 1α,25(OH)2D3 receptor. Additionally, recent evidence indicates that several cellular responses to 1α,25(OH)2D3 are mediated via a rapid, calcium-dependent membrane-mediated pathway. These actions of 1α,25(OH)2D3 can be blocked by antibodies to protein-disulfide isomerase family A, member 3 (Pdia3), indicating that it is part of th

Introduction PDIA3, also known as ERp57 or GRP58, is a member of the protein disulfide isomerase family; its structure is characterized by four thioredoxin-like domains: a, b, b’ and a’; a and a’ domains contain the redox active site while b and b’ domains are redox inactive. PDIA3 is localized predominantly in the ER (Endoplasmic Reticulum), where it is involved in the correct folding of newly synthesized glycoproteins and in the assembly of the MHC class I complex, but it is also present in the cytosol, in the nucleus and on the cell surface.
