We examined the direct effects of glucocorticoid treatment on neutrophil survival and function in vitro. Four different glucocorticoids caused a dose-dependent inhibition of apoptosis leading to increased survival of neutrophils. Maximal effects were found with dexamethasone at 10(-6) M, 16.6 +/- 6.2 vs 54.6 +/- 6.9, at 24 h (p , 0.05). Nonglucocorticoid steroids did not modulate apoptosis in neutrophils. Furthermore, the effect was inhibited in a dose-dependent manner by the glucocorticoid antagonist RU 486. Glucocorticoid-treated neutrophils produced significantly more superoxide in response to FMLP than untreated controls (p , 0.05). However, both basal and stimulated superoxide production were less than that found with freshly isolated cells. Such lack of priming or activation by glucocorticoids is in contrast to previous experience when increased survival was accompanied by cell activation. When compared with other stimuli, the effect of glucocorticoids at 24 h was similar to that of LPS ...
We have investigated the effect of long-term glucocorticoid (GC) administration on bone turnover in two frequently used mouse strains; C57BL/6J and CD1, in order to assess the influence of their genetic background on GC-induced osteoporosis (GIO). GIO was induced in 12 weeks old female C57BL/6J and CD1 mice by subcutaneous insertion of long-term release prednisolone or placebo pellets. Biomechanical properties as assessed by three point bent testing revealed that femoral elasticity and strength significantly decreased in CD1 mice receiving GC, whereas C57BL/6J mice showed no differences between placebo and prednisolone treatment. Bone turnover assessed by microcomputer tomography revealed that contrary to C57BL/6J mice, prednisolone treated CD1 mice developed osteoporosis. In vitro experiments have underlined that, at a cellular level, C57BL/6J mice osteoclasts and osteoblasts were less responsive to GC treatment and tolerated higher doses than CD1 cells.

TY - JOUR. T1 - Hydrogen peroxide signaling is required for glucocorticoid-induced apoptosis in lymphoma cells. AU - Tome, Margaret E.. AU - Jaramillo, Melba C.. AU - Briehl, Margaret M.. PY - 2011/12/1. Y1 - 2011/12/1. N2 - Glucocorticoid-induced apoptosis is exploited clinically for the treatment of hematologic malignancies. Determining the required molecular events for glucocorticoid-induced apoptosis will identify resistance mechanisms and suggest strategies for overcoming resistance. In this study, we found that glucocorticoid treatment of WEHI7.2 murine thymic lymphoma cells increased the steady-state [H 2O 2] and oxidized the intracellular redox environment before cytochrome c release. Removal of glucocorticoids after the H 2O 2 increase resulted in a 30% clonogenicity; treatment with PEG-CAT increased clonogenicity to 65%. Human leukemia cell lines also showed increased H 2O 2 in response to glucocorticoids and attenuated apoptosis after PEG-CAT treatment. WEHI7.2 cells that overexpress ...
First described for their metabolic and immunosuppressive effects, glucocorticoids are widely prescribed in clinical settings of inflammation. However, glucocorticoids are also potent inducers of apoptosis in many cell types and tissues. This review will focus on the established mechanisms of glucocorticoid-induced apoptosis and outline what is known about the apoptotic response in cells and tissues of the body after exposure to glucocorticoids. Glucocorticoid-induced apoptosis affects the skeletal system, muscular system, circulatory system, nervous system, endocrine system, reproductive system, and the immune system. Interestingly, several cell types have an anti-apoptotic response to glucocorticoids that is cytoprotective. Lastly, we will discuss the pro- and anti-apoptotic effects of glucocorticoids in cancers and their clinical implications.
The soon-to-be-delivered fetus and preterm infant have been treated with glucocorticoids to prepare for postnatal life, historically for more than 40 years. The use of glucocorticoids is as much for replacement of cortisol in the setting of a poorly functioning hypothalamic-pituitary-adrenal axis in the preterm infant, as it is for prevention of long-term lung dysfunction. Potential negative effects of glucocorticoid treatment on brain development and function have been observed more often with dexamethasone therapy than with use of other glucocorticoids. Overall, glucocorticoid treatment has improved the outcome of the preterm infant.

BACKGROUND: Glucocorticoid-induced leucine zipper (GILZ) is a mediator of the anti-inflammatory activities of glucocorticoids. However, GILZ deletion does not impair the anti-inflammatory activities of exogenous glucocorticoids in mice arthritis models and GILZ could also mediate some glucocorticoid-related adverse events. Osteoarthritis (OA) is a metabolic disorder that is partly attributed to adipokines such as leptin, and we previously observed that glucocorticoids induced leptin secretion in OA synovial fibroblasts. The purpose of this study was to position GILZ in OA through its involvement in the anti-inflammatory activities of glucocorticoids and/or in the metabolic pathway of leptin induction. The influences of ...
1. Glucocorticoids are widely used for the suppression of inflammation in chronic inflammatory diseases such as asthma, rheumatoid arthritis, inflammatory bowel disease and autoimmune diseases, all of which are associated with increased expression of inflammatory genes. The molecular mechanisms involved in this antiinflammatory action of glucocorticoids is discussed, particularly in asthma, which accounts for the highest clinical use of these agents.. 2. Glucocorticoids bind to glucocorticoid receptors in the cytoplasm which then dimerize and translocate to the nucleus, where they bind to glucocorticoid response elements (GRE) on glucocorticoid-responsive genes, resulting in increased transcription. Glucocorticoids may increase the transcription of genes coding for antiinflammatory proteins, including lipocortin-1, interleukin-10, interleukin-1 receptor antagonist and neutral endopeptidase, but this is unlikely to account for all of the widespread anti-inflammatory actions of ...
To evaluate the risk of fracture in patients receiving intermittent therapy with high-dose oral glucocorticoids (GCs).The study group comprised 191,752 patients from the UK General Practice Database who were 40 years of age and older and received therapy with GCs. The followup time period was divided into the categories of current and no exposure. The daily dose and cumulative dose for each time period were determined. Relative risks were estimated using Cox proportional hazards models, adjusted for age, sex, body mass index, smoking, disease history, and drug history. Fractures of the radius/ulna, humerus, rib, femur/hip, pelvis, or vertebrae were included in the evaluation.Patients who intermittently received high-dose GCs (daily dose | or =15 mg) and had no or little previous exposure to GCs (cumulative exposure | or =1 gm) had a small increased risk of osteoporotic (but not hip/femur) fracture; this risk increased substantially with increasing cumulative exposure. Among patients who received a
Therapy with antihistamines and oral glucocorticoids should probably continue at home for another 2-3 days to prevent recurrence.
OBJECTIVE: The frequency of many adverse events (AEs) associated with low-dose glucocorticoid use is unclear. We sought to determine the prevalence of glucocorticoid-associated AEs in a large US managed care population. METHODS: Using linked administrative and pharmacy claims, adults receiving |or=60 days of glucocorticoids were identified. These individuals were surveyed about glucocorticoid use and symptoms of 8 AEs commonly attributed to glucocorticoid use. RESULTS: Of the 6,517 eligible glucocorticoid users identified, 2,446 (38%) returned the mailed survey. Respondents were 29% men with a mean +/- SD age of 53 +/- 14 years; 79% were white and 13% were African American. Respondents had a mean +/- SD of 7 +/- 3 comorbid conditions and were prescribed a mean +/- SD prednisone-equivalent dosage of 16 +/- 14 mg/day. More than 90% of individuals reported at least 1 AE associated with glucocorticoid use; 55% reported that at least 1 AE was very bothersome. Weight gain was the most common self-reported AE
Glucocorticoids are prescribed for their immunosuppressive, antiproliferative, anti-inflammatory, and antiallergenic effects and are integral to the management of numerous conditions, including malignancies, transplantation, autoimmune and allergic d
Glucocorticoids and NSAIDs inhibit prostaglandin biosynthesis through different mechanisms. NSAIDs inhibit prostaglandin biosynthesis by noncompetitive inhibition of both COX-1 and COX-2 enzymatic activity. Glucocorticoids are the most potent, endogenous, and specific COX-2 inhibitors. Glucocorticoids suppress prostaglandin production through inhibiting cytosolic phospholipase A2 activity and suppressing COX-2 and mPGES-1 expression. The actions of glucocorticoids are regulated systemically and locally (7). Circulating glucocorticoid levels are regulated by the hypothalamic-pituitary-adrenal axis. Within target tissues, the actions of glucocorticoids are downregulated by 11ßHSD2-mediated metabolism. 11ßHSD2 is expressed predominantly in mineralocorticoid responsive tissues such as the kidney and colon to convert glucocorticoids to their inactive keto-forms, thus providing mineralocorticoid receptor selectivity to aldosterone.. Glucocorticoids are known to inhibit cell proliferation and induce ...
The glucocorticoid receptor (GR) is a major drug target in inflammatory disease. However, chronic glucocorticoid (GC) treatment leads to disordered energy metabolism, including increased weight gain, adiposity, and hepatosteatosis - all programs modulated by the circadian clock. We demonstrated that while antiinflammatory GC actions were maintained irrespective of dosing time, the liver was significantly more GC sensitive during the day. Temporal segregation of GC action was underpinned by a physical interaction of GR with the circadian transcription factor REVERBa and co-binding with liver-specific hepatocyte nuclear transcription factors (HNFs) on chromatin. REVERBa promoted efficient GR recruitment to chromatin during the day, acting in part by maintaining histone acetylation, with REVERBa-dependent GC responses providing segregation of carbohydrate and lipid metabolism. Importantly, deletion of Reverba inverted circadian liver GC sensitivity and protected mice from hepatosteatosis induced by ...
Pharmacology - Glucocorticoids have effects on virtually every cell type and system in mammals. An overview of the effects of these agents follows:. Cardiovascular System: Glucocorticoids can reduce capillary permeability and enhance vasoconstriction. A relatively clinically insignificant positive inotropic effect can occur after glucocorticoid administration. Increased blood pressure can result from both the drugs vasoconstrictive properties and increased blood volume that may be produced.. Cells: Glucocorticoids inhibit fibroblast proliferation, macrophage response to migration inhibiting factor, sensitization of lymphocytes and the cellular response to mediators of inflammation. Glucocorticoids stabilize lysosomal membranes.. CNS/Autonomic Nervous System: Glucocorticoids can lower seizure threshold, alter mood and behavior, diminish the response to pyrogens, stimulate appetite and maintain alpha rhythm. Glucocorticoids are necessary for normal adrenergic receptor sensitivity.. Endocrine ...
Glucocorticoids Definition Glucocorticoids are naturally-produced steroid hormones, or synthetic compounds, that inhibit the process of inflammation. Purpose The target of glucocorticoids: inflammation Glucocorticoids are used to stop the inflammation process.
Muscle wasting is associated with a number of pathophysiologic conditions, including metabolic acidosis, diabetes, sepsis, and high angiotensin II levels. Under these conditions, activation of muscle protein degradation requires endogenous glucocorticoids. As the mechanism(s) underlying this dependence on glucocorticoids have not been identified, we analyzed the effects of glucocorticoids on muscle wasting in a mouse model of acute diabetes. Adrenalectomized, acutely diabetic mice given a physiologic dose of glucocorticoids exhibited decreased IRS-1-associated PI3K activity in muscle and progressive muscle atrophy. These responses were related to increased association of PI3K with the glucocorticoid receptor (GR). In mice with muscle-specific GR deletion (referred to as MGRKO mice), acute diabetes minimally suppressed IRS-1-associated PI3K activity in muscle and did not cause muscle atrophy. However, when a physiologic dose of glucocorticoids was given to mice with muscle-specific IR deletion, ...

We investigated the expression differences of the TEL-AML1 fusion gene in a leukemia glucocorticoid (GC)-sensitive cell line (CEM) and a GC-resistant cell line (Jurkat). Changes in TEL-AML1 expression before and after GC exposure were analyzed. Expression of GC-sensitive and GC-resistant leukemia cells following initial diagnosis and during treatment was simulated. Leukemia cells were divided into a GC-unexposed or a GC-exposed group.
A number of childhood conditions that require chronic GC therapy may themselves predispose the child to abnormalities of growth and bone health. For instance, poor linear growth and osteoporosis may be presenting features in a child with inflammatory bowel disease. The interaction with other factors such as inflammatory cytokine production, diminished physical activity, alterations in nutritional status, and the use of other immunomodulatory agents that may also have bone adverse effects greatly increase the risks posed to the growth and bone health of the child on chronic GC therapy.. The clinical effects on bone health can be divided into those occurring in the short term (fractures and avascular necrosis) and those that may occur over the longer term-that is, increased predisposition for osteoporosis and skeletal deformity. Current studies and clinical observations suggest that children who require long term systemic GC therapy (for more than three months) have a higher incidence of fractures ...
In patients presenting to the emergency department with acute exacerbations of COPD, 5-day treatment with systemic glucocorticoids was non-inferior to 14-day treatment with regard to re-exacerbation within 6 months of follow-up but significantly reduced glucocorticoid exposure. These findings support the use of a 5-day glucocorticoid treatment in acute exacerbations of COPD ...

In the present work, we have set up and propose a rational computational analysis framework, in order to aid the elucidation of the molecular mechanisms of glucocorticoid resistance and specifically whether these are to a larger extent inherent or acquired. To the best of our knowledge, there are no reports trying to analyze systematically the underlying, inherent or acquired molecular mechanisms of GC resistance. The issue whether leukemic cells possess the inherent genetically imprinted resistance mechanisms or it is rather a post effect of evolutionary adoption of originally sensitive cells upon GC treatment is still a controversial one, with potentially significant interest for design of novel therapeutic approaches in cancer treatment. A similar work [77] reported recently that in ex vivo samples, leukemic cells exhibit an at least in part, intrinsic mechanism of reaction. In another work [78], it has also been mentioned that glucocorticoids can induce intrinsic mechanisms of GC-resistance ...
The most important first step in the management of patients with suspected Cushings syndrome is to establish the correct diagnosis. Most mistakes in clinical management, leading to unnecessary imaging or surgery, are made because the diagnostic protocol is not followed (Fig. 342-9). This protocol requires establishing the diagnosis of Cushings beyond doubt prior to employing any tests used for the differential diagnosis of the condition. In principle, after excluding exogenous glucocorticoid use as the cause of clinical signs and symptoms, suspected cases should be tested if there are multiple and progressive features of Cushings, particularly features with a potentially higher discriminatory value. Exclusion of Cushings is also indicated in patients with incidentally discovered adrenal masses. ...
This project will study blood obtained from babies shortly after birth and in guinea pigs early in life to discover how genes throughout the genome respond to glucocorticoid treatment. This research has important implications for the fundamental understanding of biological responses to glucocorticoid treatment. The team anticipates that this study will ultimately inform clinical practice in Canada, where a majority of women at risk of preterm birth (more than 10% of all pregnancies) are treated with glucocorticoids in pregnancy.. ...
A new study reveals that steroid injections used to prevent premature birth might increase future risks of behavioral and emotional problems in the developing children.. Expectant mothers who might give birth prematurely are often treated with an infusion of glucocorticoids. These drugs, wrote Psych Central, are cortisol mimickers; cortisol is a natural hormone. The treatment is meant to assist in the developing babys lung development; however new concerns have arisen that high glucocorticoids exposure in the womb might lead to dangerous, long-term effects on brain development.. Cortisol is naturally produced in the fetus during later pregnancy stages and works to help the lungs develop appropriately, according to Medical Daily. Premature babies often miss this important development stage, which leads to lung problems and life-threatening breathing issues.. Synthetic glucocorticoids are known to copy the effect of natural cortisol and, when given prior to birth, the glucocorticoid, ...

Glucocorticoid therapy is associated with an appreciable risk of bone loss, which is most pronounced in the first few months of use. In addition, glucocorticoids increase fracture risk, and fractures occur at higher bone mineral density (BMD) values
Dexamethasone (Dex) pretreatment significantly increased cardiac contractile force ex vivo in Langendorff-perfused Sprague-Dawley rat hearts (2 mg/kg BW i.p. Dex 24 h prior to experiment). Moreover, Ca transient amplitude as well as fractional shortening were significantly enhanced in Fura-2-loaded isolated rat ventricular myocytes exposed to Dex (1 mg/mL Dex, 24 h). Interestingly, these Dex-dependent effects could be abolished in the presence of SOCE-inhibitors SKF-96356 (SKF, 2 μM) and BTP2 (5 μM). Ca transient kinetics (time to peak, decay time) were not affected by SOCE stimulation. Direct SOCE measurements revealed a negligible magnitude in untreated myocytes but a dramatic increase in SOCE upon Dex-pretreatment. Importantly, the Dex-dependent stimulation of SOCE could be blocked by inhibition of serum and glucocorticoid-regulated kinase 1 (SGK1) using EMD638683 (EMD, 50 μM). Dex preincubation also resulted in increased mRNA expression of proteins involved in SOCE (stromal interaction ...
Even though many in the ALS money making industry maintain otherwise, there is no question that ALS is an autoimmune disease. This is why my wife and other ALS sufferers have experienced strong improvements after injection with anti-inflammatory drugs. This is not the first time that glucocorticoid drugs have been implicated in spectacular ALS remissions. In 2011, famous ALS patient Ted Harada experienced an amazing recovery after being anesthetized for up to five hours during stem cell treatment and given several anti-inflammatory glucocorticoids to prevent rejection. In June 2013, Ernie Schmid published an ALS remission story in which he explained how he kept his ALS under control with powerful glucocorticoids. There is also the story of US Authors Guilds director Paul Aiken whose ALS went into remission after injections with the glucocorticoid drug Kenalog. Other ALS sufferers have reported strong improvements in their speech and ability to swallow after a visit to the dentist. It turns out ...

2464 Glucocorticoids (GCs) are a crucial component in all protocols for the treatment of human lymphoid malignancies, including childhood acute lymphoblastic leukemia (ALL). A central role in GC-mediated apoptosis is played by the proapoptotic BH3-only proteins, most notably Bim, Puma and, to a lesser extent, Noxa. Following exposure to GCs, these genes are upregulated at the mRNA and protein level. Silencing of Bim using siRNA technology correlates with protection from GC induced apoptosis in ALL cell lines. To dissect the molecular mechanisms leading to GC resistance in vivo, we developed a model of childhood ALL, using patient biopsies established as xenografts in immune-deficient (NOD/SCID) mice. Using this model, we demonstrated that resistance is typically associated with failure to induce Bim mRNA and protein in response to GC treatment. Using a methylated DNA immunoprecipitation analysis of the entire Bim CpG island, we found that increased methylation of Bim 5 Untranslated Region ...
Our results showed that poly(I:C), a TLR3 agonist, up-regulated the production of inflammatory cytokines/chemokines such as MIP1-α, MIP1-β, RANTES, IL-6, and IL-8, by activating NFκB. Incubation of HCECs with poly(I:C) also activated IRF3 followed by IFN-β production. The up-regulated expression of TLR 3 by poly(I:C) indicates that the TLR3/TRIF signaling pathways were most likely activated by poly(I:C) in HCECs. This is consistent with previous reports [1,15-17]. The cytokines and chemokines investigated are known to have powerful effects in recruiting immune cells and stimulating the maturation of dendritic cells [29-31]. Therefore, we suggest that corneal epithelial cells, when the TLR3s are activated de novo, are able to recruit and activate immune cells against viral infections. Our results showed that DEX and CsA inhibit the poly(I:C)-induced NFκB activation and the subsequent production of inflammatory cytokines/chemokines. Earlier studies have shown that the concentration of ...
Those subjects on other oral anti-rheumatic therapies, which may include Non Steroidal Anti Inflammatory Drugs (NSAIDs), COX-2 inhibitors, oral glucocorticoids e.g. prednisolone (£10mg/day) must be on stable dosing regimens for at least 4 weeks prior to screening and be willing to remain on this regime throughout the study. Subjects receiving intramuscular glucocorticoids e.g methylprednisolone (£120 mg/month) must be on a stable dosing regimen for at least 3 months prior to screening and be willing to remain on this regimen throughout the study ...
This NMA has provided no clear evidence that any one intervention or treatment regimen is better than any other across the spectrum of outcomes. The use of glucocorticoids in the critically ill is commonplace, but its targets and true indications are hazy. There have been three indications for the use of glucocorticoids in sepsis over the last century. First, they were given as immunosuppressants; large doses of glucocorticoids that have significant immune effects such as dexamethasone and methylprednisolone were given until studies in the late 1980s [23-27] showed a trend towards increased rates of superinfection and these high dose studies were halted. Second, there have been attempts to identify and treat a group of patients who are thought to be relatively deficient in glucocorticoids during their critical illness (critical illness-related corticosteroid insufficiency [1]), although sensitive and specific diagnostic tests for this remain to be found [28-31]. Last, and more recently, there ...

Glucocorticoid-induced leucine zipper (GILZ) is a mediator of the anti-inflammatory activities of glucocorticoids. However, GILZ deletion does not impair the anti-inflammatory activities of exogenous glucocorticoids in mice arthritis models and GILZ could also mediate some glucocorticoid-related adverse events. Osteoarthritis (OA) is a metabolic disorder that is partly attributed to adipokines such as leptin, and we previously observed that glucocorticoids induced leptin secretion in OA synovial fibroblasts. The purpose of this study was to position GILZ in OA through its involvement in the anti-inflammatory activities of glucocorticoids and/or in the metabolic pathway of leptin induction. The influences of mineralocorticoids on GILZ and leptin expression were also investigated. Human synovial fibroblasts were isolated from OA patients during knee replacement surgery. Then, the cells were treated with a glucocorticoid (prednisolone), a mineralocorticoid (aldosterone), a glucocorticoid receptor (GR)

It is generally accepted that bone formation is depressed during corticosteroid treatment, but the effects of glucocorticoids on bone resorption are less well characterized. We have investigated the effects of short-term treatment with high-dose oral glucocorticoids on biochemical markers of bone turnover in 20 consecutive patients with asthma who sought help for acute respiratory obstruction in our emergency department. Serum concentrations of the carboxy-terminal cross-linked telopeptide of type 1 collagen (1CTP), reflecting bone resorption, and the carboxy-terminal propeptide of type 1 procollagen (P1CP), reflecting bone formation, were measured by radioimmunoassay. Changes of the circulating levels of the bone resorption marker 1CTP after treatment were age dependent with a significant negative correlation (r = -0.54, P = 0.01). The dependency on age remained when correcting, in a multiple linear regression analysis, for 1CTP levels at admission, weight, sex, and daily maintenance dose of ...
OBJECTIVE: The metabolic effects of low-dose prednisolone and optimal management of glucocorticoid-induced diabetes are poorly characterized. The aims were to investigate the acute effects of low-dose prednisolone on carbohydrate metabolism and whether long-term low-dose prednisolone administration increases visceral adiposity, amplifying metabolic perturbations. RESEARCH DESIGN AND METHODS: Subjects with inflammatory rheumatologic disease without diabetes mellitus were recruited. Nine subjects (age, 59 +/- 11 years) not using oral glucocorticoids were studied before and after a 7- to 10-day course of oral prednisolone 6 mg daily. Baseline data were compared with 12 subjects (age, 61 +/- 8 years) using continuous long-term prednisolone (6.3 +/- 2.2 mg/day). Basal endogenous glucose production (EGP) was estimated by 6,6-(2)H2 glucose infusion, insulin sensitivity was estimated by two-step hyperinsulinemic-euglycemic clamp, insulin secretion was estimated by intravenous glucose tolerance test, and adipose
To determine if a patient has glucocorticoid-induced osteoporosis, you can measure the bone mineral density (BMD) at different parts of the patients body, such as the spine and hip. Dual energy X-ray absorptiometry (DXA) is currently the best test to measure BMD. The test is quick and painless; it is similar to having an X-ray taken, but uses much less radiation. DXA results are scored in comparison to the BMD of young, healthy individuals, resulting in a measurement called a T-score. Patients with T-scores of -2.5 or lower are considered to have osteoporosis and are at a higher risk for a fracture.. According to patient fact-sheet writer Shreyasee Amin, MD, "the major goal in the management of glucocorticoid-induced osteoporosis is the prevention of fractures and to help decrease bone loss." At a minimum, she suggests that "patients should take 1,000 to 1,500 milligrams of calcium and 400 to 800 IU of vitamin D supplements on a daily basis.". ...
Results Both groups of patients were matched in gender, disease type and cumulative glucocorticoid dose (p,0.1). Patients in the fracture group were older (63±14 vs 59±12 years, p,0.01), of lower body mass index [22.7±3.5vs 24±3.7kg/m2, p,0.05], with a higher prevalence of previous fracture [38 (34.5%) vs 5 (4.5%), p,0.01], use of vitamin D [77 (70%)vs 54 (49.1%), p,0.01] and bisphosphonates [23 (20.9%) vs 7 (6.4%), p,0.01]. A receiver operating characteristic (ROC) curve analysis was performed to determine the ability of FRAX score with or without BMD and BMD alone to discriminate fracture status (Table 1). BMD at the femoral neck and FRAX score with BMD were able to provide adequate discrimination with their area under curve (AUC) ,0.70. With regards to treatment indication, only 53/110 (48.2%) of the patients with vertebral fracture were identified as having osteoporosis (T-score ≤ -2.5 at hip/spine) by DXA. In contrast, FRAX with BMD were able to identify 71/110 (64.5%) of the fracture ...
Tenascin, a predominantly mesenchymal extracellular matrix (ECM) glycoprotein has a rather restricted tissue distribution, but until now factors that inhibit its expression have not been identified. Glucocorticoids are known to be beneficial for establishment of myelopoiesis in long-term bone marrow cultures. Tenascin was found to be expressed in the bone marrow, and glucocorticoids were found to affect bone marrow tenascin expression. Both tenascin mRNAs and the mRNA of another ECM protein, laminin B1 chain, were drastically downregulated by glucocorticoids during initiation of bone marrow cultures. However, in already established long-term cultures glucocorticoids did not affect laminin B1 chain mRNA levels although tenascin mRNAs continued to be downregulated. Studies with a stromal cell line (MC3T3-G2/PA6) and fibroblasts (3T3) suggested that glucocorticoids act directly on the stromal cells that produce tenascin. In 3T3 cells this downregulation occurred within 12 h of ...

Developmentally, the pancreas and liver are closely related and pathological conditions − including elevated glucocorticoid levels − result in the appearance of hepatocytes in the pancreas. The role of the WNT signalling pathway in this process has been examined in the model transdifferentiating pancreatic acinar AR42J-B-13 (B-13) cell. Glucocorticoid treatment resulted in a transient loss of constitutive WNT3a expression, phosphorylation and depletion of β-catenin, loss of β-catenin nuclear localisation, and significant reductions in T-cell factor/lymphoid enhancer factor (Tcf/Lef) transcriptional activity before overt changes in phenotype into hepatocyte-like (B-13/H) cells. A return to higher Tcf/Lef transcriptional activity correlated with the re-expression of WNT3a in B-13/H cells. β-catenin knock down alone substituted for and enhanced glucocorticoid-dependent transdifferentiation. Overexpression of a mutant β-catenin (pt-Xβ-cat) protein that blocked glucocorticoid-dependent ...
