Hydrocortisone induces changes in gene expression and differentiation of immature human enterocytes

ABSTRACT: It It is known that functional maturation of the small intestine occurring during the weaning period is facilitated by glucocorticoids (such as hydrocortisone, HC) including the increased expression of digestive hydrolases. However, the molecular mechanism(s) are not well understood, particularly in human gut. Here we report a microarray analysis of HC- induced changes in gene expression in H4 (a human fetal small intestinal epithelial cell line well-characterized in numerous previous studies). This study identified a large number of HC-affected genes, some involved in metabolism, cell cycle regulation, cell polarity, tight junction formation, and interactions with extracellular matrices. These effects could play an important role in HC-mediated enterocyte maturation in vivo and in vitro. hydrocortisone effect on gene expression prlfile in H4 cells over time (no HC, HC_12h, HC_24h, HC_48h, HC_5d and T84). Six samples are analyzed. Control sample is H4 without HC.

Effects of Systemically Administered Hydrocortisone on the Human Immunome

Project description:Corticosteroids have been prescribed for decades to modulate inflammation, yet there is a paucity of data on their effects in humans. We examined the changes in cellular and molecular immune system parameters, or âimmunome,â in 20 volunteers at baseline, and after intravenous hydrocortisone (HC) administered at moderate (250 mg) and low (50 mg) doses, to provide insight into how corticosteroids exert their effects. We observed declines in specific B and T cell subsets, and an increase in natural killer cell subsets 4-8 hours after HC. Whole transcriptome profiling revealed a gene expression signature that preceded lymphocyte population changes. We observed decreases in inflammatory cytokines after HC administration. Our study provides insights into the effects of corticosteroids on the human immunome. According to CHI protocols 11-H-0092, 18 healthy volunteers were administered a single dose of intravenous (IV) hydrocortisone at either 50 mg or 250 mg concentrations. PBMC samples were collected immediately prior to receiving the drug (0 hours), then after 1, 4, 8, 12, and 24 hours.

RNA-seq of human osteosarcoma cell line Mg63 treated with hydrocortisone against untreated controls

Project description:The purpose of this study was to investigate the effects of hydrocortisone on osteosarcoma cells and its molecular mechanism, so as to determine whether they can be new therapeutic agents for osteosarcoma. osteosarcoma cells were cultured in vitro and they were divided into control group and HC group. transcriptome sequencing and bioinformatics analysis were performed to analyze the effect of the drugs.

Prospective randomized doubleblind assessment of transcriptome modulation by hydrocortisone in severe burn shock

Project description:Rationale: Despite shortening vasopressor use in shock, hydrocortisone administration remains controversial, with potential harm on the immune system. Few studies assessed hydrocortisone impact on the transcriptional response in shock, and we are lacking data in burns. Objectives: To assess the hydrocortisone-induced transcriptional modulation in severe burn shock, particularly on the immune response. Methods: We collected whole blood samples (n= 117) during a randomized controlled trial assessing the efficacy of hydrocortisone administration on burn shock. Using whole genome microarrays, we first compared burn patients from the placebo group (n=15) to healthy volunteers (n=13) to describe the transcriptional modulation induced by burn shock over the first week. Then we compared burn patients randomized for either hydrocortisone administration (n=15) or placebo (n=15) to assess hydrocortisone-induced modulation. Measurements and Main Results: Study groups were similar in terms of severity and major outcomes, but shock duration (significantly reduced in the hydrocortisone group). Many genes (n=2250) were differentially expressed between burn patients and healthy volunteers, with 85% of them exhibiting a profound and persistent modulation over seven days. Interestingly, we showed that hydrocortisone enhanced the shock-associated repression of adaptive, but also innate immunity. Conclusions: We found that the initial host response to burn shock encompasses a wide and persistent modulation of gene expression, with profound modulation of pathways associated with metabolism and immunity. Importantly, hydrocortisone administration may worsen the immunosuppression associated with severe injury. These data should be taken into account in the risk ratio of hydrocortisone administration in patients with inflammatory shock.

Hydrocortisone and Triiodothyronine Regulate Hyaluronate Synthesis in a Tissue–Engineered Human Dermal Equivalent through Independent Pathways

Project description:Hydrocortisone (HC) and triiodothyronine (T3) have both been shown to be capable of independently inhibiting hyaluronate (HA, hyaluronic acid) synthesis in a self-assembled human dermal equivalent (human dermal matrix). We sought to investigate the action of these two hormones in concert on extracellular matrix formation and HA inhibition in a tissue engineered human dermal matrix. RNA preparations were sent to CFG Microarray Core (E). Three replicate samples from each condition were used in the study. The RNA was amplified, labeled, and hybridized to the GLYCOv4 microarrays.

RNA sequencing of enterocytes differentiated from human iPS cells [RNAseq1]

Project description:Our RNA-seq results show the changes in gene expression during differentiation and maturation of iPS-derived enterocytes, as well as that treatment during the last stage with Vitamin D3 (VD3) enhanced enterocyte-related gene expression. Caco-2 and RNA from human adult small intestine were also sequenced as comparison.

Project description:It is known that functional maturation of the small intestine occurring during the weaning period is facilitated by glucocorticoids (such as hydrocortisone, HC), including an increased expression of digestive hydrolases. However, the molecular mechanisms are not well understood, particularly in the human gut. Here we report a microarray analysis of HC-induced changes in gene expression in H4 cells (a well-characterized human fetal small intestinal epithelial cell line). This study identified a large number of HC-regulated genes, some involved in metabolism, cell cycle regulation, cell-cell or cell-extracellular matrix communication. HC also regulates the expression of genes important for cell maturation such as development of cell polarity, tight junction formation, and interactions with extracellular matrices. Using human small intestinal xenografts, we also show that HC can regulate the expression of genes important for intestinal epithelial cell maturation. Our dataset may serve as a useful resource for understanding and dissecting the molecular mechanisms of intestinal epithelial cell maturation.
