Texto completoBecause of their anti-inflammatory properties, corticosteroids are an essential treatment for numerous diseases. Corticosteroids are used by about 3% of the global population, mainly to treat inflammatory diseases such as asthma or rheumatoid arthritis. Although corticosteroid therapy is highly effective, it leads to numerous side effects, including metabolic dysregulations, bone resorption, and hormonal deficiencies. Corticosteroid-induced adrenal insufficiency is one of the most frequent side effects. As sensitivity to corticosteroids is highly variable between individuals and remains poorly understood, evaluating the individual risk of side effects susceptibility is difficult. This thesis focused on the genetic factors involved in the inter-individual variability of corticosteroid sensitivity.First, we investigated several variants of the NR3C1 gene encoding the glucocorticoid receptor (GR). The GR mediates the effects of glucocorticoids at the cellular level. We characterized 3 NR3C1 variants in vitro by assessing the transcriptional activity of the GR, target genes expression, and nuclear translocation in response to agonists. For the first 2 variants, we demonstrated a decreased transcriptional activity of the GR, which was associated with reduced nuclear translocation and target gene expression. These variants resulted in a structural modification of the GR and are responsible for the primary glucocorticoid resistance phenotype. We also characterized the N363S variant by developing a genetically modified cell and mouse model. The N363S variant is found in 2% of the population and is associated with increased glucocorticoid sensitivity. Characterization of the mouse model revealed no specific phenotype associated with the variant expression under basal conditions. Evaluation of the phenotype under corticoid treatment is currently ongoing. Next, we focused on the genes encoding the CYP3A4 and CYP3A5 enzymes. The CYP3A4/5 enzymes are involved in glucocorticoid hormone metabolism, particularly in the hepatic first-pass metabolism of inhaled corticosteroids. We identified a homozygous loss-of-function variant of the CYP3A4 gene together with a homozygous loss-of-function polymorphism of the CYP3A5 gene in a patient presenting with glucocorticoid hypersensitivity after moderate-dose inhaled corticosteroid therapy. Absence or reduction of CYP3A4/5 activity may constitute a risk factor that can be evaluated to prevent inhaled corticosteroid-induced complications.Finally, we studied the effect of prolonged dexamethasone treatment on pituitary corticotroph cells function. We treated AtT-20/D16v corticotroph cells, a well-characterized model for studying negative feedback regulation of the hypothalamic-pituitary-adrenal (HPA) axis by glucocorticoids. Transcriptome analysis of cells after 7 days of dexamethasone treatment showed significant and persistent modifications, as the transcriptome did not normalize 7 days after dexamethasone withdrawal. We identified differential expression of specific genes that were overexpressed during the recovery period compared to both treated and control conditions, suggesting a role for these genes in HPA axis recovery.Overall, we believe that a better understanding of genetic factors involved in inter-individual variability in sensitivity to glucocorticoids and corticotropic axis recovery will improve the management of patients treated with corticosteroids to achieve a personalized medicine approach
Zein, Naïmah. "“CpdX”, a non-steroidal Selective Glucocorticoid Receptor Agonistic Modulator (SEGRAM) selectively triggers the beneficial anti-inflammatory activity of glucocorticoids, but not their long-term debilitating effects". Thesis, Strasbourg, 2018. http://www.theses.fr/2018STRAJ088.
Texto completoUpon binding of natural or synthetic glucocorticoids (GCs) (e.g. Dexamethasone) to their glucocorticoid receptor (GR), GCs regulate the expression of target genes either by (i) direct transactivation through direct binding to “(+)GRE” DNA binding sites (DBS), (ii) direct transrepression through binding to “IR nGRE” DBSs or (iii) tethered indirect transrepression mediated through interaction with transactivators, such as NFkB, AP1, or STAT3 bound to their cognate DBSs. The beneficial anti-inflammatory effects of GCs have been generally ascribed to tethered transrepression, whereas many of their long-term undesirable side-effects could be due to transactivation and/or direct transrepression. Our laboratory recently reported that a non-steroidal compound, named CpdX, selectively lacks both direct transactivation and direct transrepression functions, while still exerting an indirect transrepression activity. The goal of our project was to characterize CpdX and some of its derivatives as effective anti-inflammatory drugs similar to glucocorticoids, but lacking their main deleterious side-effects, e.g. osteoporosis, skin atrophy and metabolic disorders. To this end, we have used experimental mouse model for skin disorders (atopic dermatitis, contact dermatitis, and psoriasis), asthma, rheumatoid arthritis, ulcerative colitis and allergic conjunctivitis, combined with immunology, molecular and cellular biology. My thesis studies have demonstrated that in mouse models, CpdX and its derivatives exhibit anti-inflammatory activities, which are similar to those of glucocorticoids (Part I). Importantly, we further show that CpdX and its derivatives do not exhibit the long-term debilitating side-effects of glucocorticoids (Part II). Thereby paving the way to a new era in the long-term therapy of major inflammatory diseases
