Published: February 2014

ObjectiveLupus develops when genetically predisposed people encounter environmental agents, such as ultraviolet light, silica, infections, and cigarette smoke, that cause oxidative stress, but how oxidative damage modifies the immune system to cause lupus flares is unknown. We previously showed that inhibiting DNA methylation in CD4+ T cells by blocking ERK pathway signaling is sufficient to alter gene expression, and that the modified cells cause lupus‐like autoimmunity in mice. We also reported that T cells from patients with active lupus have decreased ERK pathway signaling, have decreased DNA methylation, and overexpress genes normally suppressed by DNA methylation. This study was undertaken to test whether oxidizing agents decrease ERK pathway signaling in T cells, decrease DNA methyltransferase levels, and cause demethylation and overexpression of T cell genes similar to that found in T cells from patients with active lupus.MethodsCD4+ T cells were treated with the oxidizers H2O2 or ONOO−. Effects on ERK pathway signaling were measured by immunoblotting, DNA methyltransferase 1 (DNMT‐1) levels were measured by reverse transcriptase–polymerase chain reaction (RT‐PCR), and the methylation and expression of T cell genes were measured using flow cytometry, RT‐PCR, and bisulfite sequencing.ResultsH2O2 and ONOO− inhibited ERK pathway signaling in T cells by inhibiting the upstream regulator protein kinase Cδ, decreased DNMT‐1 levels, and caused demethylation and overexpression of genes previously shown to be suppressed by DNA methylation in T cells from patients with active lupus.ConclusionOur findings indicate that oxidative stress may contribute to human lupus flares by inhibiting ERK pathway signaling in T cells to decrease DNMT‐1 and cause DNA demethylation.

ObjectiveActive rheumatoid arthritis (RA) during pregnancy and the presence of rheumatoid factor (RF) or anti–citrullinated protein antibodies (ACPAs) are associated with lower birth weight of the child. Moreover, treatment of the mothers with prednisone may shorten the gestational age at birth. Rapid catch‐up in weight for length during the first year of life has been related to a worse cardiovascular and metabolic profile in early adulthood. This study was therefore undertaken to assess the influence of RA disease activity, medication use, and presence of RF or ACPAs during pregnancy on the growth of the child in the first year of life.MethodsAmong 180 children born to mothers with RA, the tempo of catch‐up in weight during the first year of life was studied. Independent variables were the extent of RA disease activity (according to the Disease Activity Score in 28 joints [DAS28]), medication use, and presence of RF or ACPAs during pregnancy.ResultsOf 167 children with available data, 52 (31%) showed catch‐up in weight in the first year of life, of whom 90% (47 of 52) showed rapid catch‐up. An elevated DAS28 score in the mother was associated with rapid catch‐up in weight of the offspring, independent of maternal medication use or the presence of RF or ACPAs during pregnancy (odds ratio 1.44 [95% confidence interval 1.07–1.95] per 1‐point increase in the DAS28). Use of medications during pregnancy had no influence on postnatal growth.ConclusionElevated RA disease activity during pregnancy should be avoided because it is associated with rapid postnatal catch‐up in weight, a risk factor for a worse cardiovascular and metabolic profile in adults. Medication for RA during pregnancy, including prednisone, had no effect on growth. Continuation or extension of medication will not only improve maternal health during pregnancy, but could be beneficial for the future health of the unborn child.

Published: February 2014

ObjectiveCarboxyl terminus of Hsp70‐interacting protein (CHIP or STUB1) is an E3 ligase that regulates the stability of several proteins involved in tumor growth and metastasis. However, the role of CHIP in bone growth and bone remodeling in vivo has not been reported. This study was undertaken to investigate the role and mechanism of CHIP in regulation of bone mass and bone remodeling.MethodsThe bone phenotype of Chip−/− mice was assessed by histologic, histomorphometric, and micro–computed tomographic analyses. The mechanism by which CHIP regulates the degradation of tumor necrosis factor receptor–associated factor 6 (TRAF6) and the inhibition of NF‐κB signaling was examined by immunoprecipitation, Western blot, and luciferase reporter assays.ResultsDeletion of the Chip gene led to an osteopenic phenotype and increased osteoclast formation. TRAF6, an adaptor protein that is a key regulator of NF‐κB signaling and is critical for RANKL‐induced osteoclastogenesis, was up‐regulated in osteoclasts from Chip−/− mice. CHIP interacted with TRAF6 to promote TRAF6 ubiquitination and proteasome degradation. Further, CHIP inhibited p65 nuclear translocation, leading to the repression of TRAF6‐mediated NF‐κB transcription.ConclusionCHIP inhibits NF‐κB signaling by promoting TRAF6 degradation and plays an important role in osteoclastogenesis and bone remodeling. These findings suggest that CHIP may be a novel therapeutic target in bone loss–associated disorders.

Published: February 2014

ObjectiveInterstitial lung disease (ILD) is the leading cause of death in patients with systemic sclerosis (SSc; scleroderma). Although SSc‐related ILD is more common and severe in African Americans than in Caucasians, little is known about factors underlying this significant health disparity. The aim of this study was to examine the role that low expression of caveolin‐1 might play in susceptibility to ILD among African Americans.MethodsAssays of monocyte migration toward stromal cell–derived factor 1 (SDF‐1) were performed using monocytes from Caucasian and African American healthy donors and patients with SSc. For fibrocyte differentiation studies, total peripheral blood mononuclear cells were incubated on fibronectin‐coated plates. Protein expression was evaluated by immunohistochemistry and Western blotting.ResultsMonocytes from healthy African American donors and those from patients with SSc had low caveolin‐1 levels, enhanced migration toward the CXCR4 ligand SDF‐1, and enhanced differentiation to fibrocytes. Enhanced migration and differentiation of monocytes from African Americans and patients with SSc appeared to be attributable to the lack of caveolin‐1, because restoring caveolin‐1 function using a caveolin‐1 scaffolding domain peptide inhibited these processes. Although they differed from monocytes from Caucasians, monocytes from both African Americans and patients with SSc were not identical, because SSc monocytes showed major increases from baseline in ERK, JNK, p38, and Smad2/3 activation, while monocytes from African Americans showed only limited ERK activation and no activation of JNK, p38, or Smad2/3. In contrast, SDF‐1 exposure caused no additional ERK activation in SSc monocytes but did cause significant additional activation in monocytes from African Americans.ConclusionAfrican Americans may be predisposed to SSc‐related ILD due to low baseline caveolin‐1 levels in their monocytes, potentially affecting signaling, migration, and fibrocyte differentiation. The monocytes of African Americans may lack caveolin‐1 due to high levels of transforming growth factor β in their blood.

AbstractNoninvasive imaging has been widely applied for monitoring antiangiogenesis therapy in cancer drug discovery. In this report, we used different imaging modalities including high‐frequency ultrasound (HFUS), dynamic contrast enhanced‐MR (DCE‐MR), and fluorescence molecular tomography (FMT) imaging systems to monitor the changes in the tumor vascular properties after treatment with γ‐secretase inhibitor PF‐03084014. Sunitinib was tested in parallel for comparison. In the MDA‐MB‐231Luc model, we demonstrated that antiangiogenesis was one of the contributing mechanisms for the therapeutic effect of PF‐03084014. By immunohistochemistry and FITC‐lectin perfusion assays, we showed that the vascular defects upon treatment with PF‐03084014 were associated with Notch pathway modulation, evidenced by a decrease in the HES1 protein and by the changes in VEGFR2 and HIF1α levels, which indicates down‐stream effects. Using a 3D power Doppler scanning method, ultrasound imaging showed that the% vascularity in the MDA‐MB‐231Luc tumor decreased significantly at 4 and 7 days after the treatment with PF‐03084014. A decrease in the tumor vessel function was also observed through contrast‐enhanced ultrasound imaging with microbubble injection. These findings were consistent with the PF‐03084014‐induced functional vessel changes measured by suppressing the Ktrans values using DCE‐MRI. In contrast, the FMT imaging with the AngioSence 680EX failed to detect any treatment‐associated tumor vascular changes. Sunitinib demonstrated an outcome similar to PF‐03084014 in the tested imaging modalities. In summary, ultrasound and DCE‐MR imaging successfully provided longitudinal measurement of the phenotypic and functional changes in tumor vasculature after treatment with PF‐03084014 and sunitinib.

Published: February 2014

AbstractNovel mono and dialkylbipyridinium (viologens) cations combined with iodide, bromide, or bis(trifluoromethanesulfonyl)imide [NTf2] as anions were developed. Selective alkylation synthetic methodologies were optimized in order to obtain the desired salts in moderate to high yields and higher purities. All prepared mono‐ and dialkylbipyridinium salts were completely characterized by 1H, 13C, and 19F NMR spectroscopy, Fourier‐transform IR spectroscopy, and elemental analysis (in the case of NTf2 salts). Melting points, glass transition temperatures by differential scanning calorimetry (DSC) studies, and decomposition temperatures were also checked for different prepared organic salts. Viscosities at specific temperatures and activation energies were determined by rheological studies (including viscosity dependence with temperature in heating and cooling processes). Electrochemical studies based on cyclic voltammetry (CV), differential pulsed voltammetry (DPV), and square‐wave voltammetry (SWV) were performed in order to determine the redox potential as well as evaluate reversibility behavior of the novel bipyridinium salts. As proof of concept, we developed a reversible liquid electrochromic device in the form of a U‐tube system, the most promising dialkylbipyridinium‐NTf2 ionic liquid being used as the electrochromic material and the room‐temperature ionic liquid (RTIL), 1‐ethyl‐3‐methylimidazolium bis(trifluoromethanesulfonyl)‐imide [EMIM][NTf2], as a stable and efficient electrolyte.

AbstractThe stability trends across the lanthanide series of complexes with the polyaminocarboxylate ligands TETA4− (H4TETA=2,2′,2′′,2′′′‐(1,4,8,11‐tetraazacyclotetradecane‐1,4,8,11‐tetrayl)tetraacetic acid), BCAED4− (H4BCAED=2,2′,2′′,2′′′‐{[(1,4‐diazepane‐1,4‐diyl)bis(ethane‐2,1‐diyl)]bis(azanetriyl)}tetraacetic acid), and BP18C62− (H2BP18C6=6,6′‐[(1,4,10,13‐tetraoxa‐7,16‐diazacyclooctadecane‐7,16‐diyl)bis(methylene)]dipicolinic acid) were investigated using DFT calculations. Geometry optimizations performed at the TPSSh/6‐31G(d,p) level, and using a 46+4fn ECP for lanthanides, provide bond lengths of the metal coordination environments in good agreement with the experimental values observed in the X‐ray structures. The contractions of the Ln3+ coordination spheres follow quadratic trends, as observed previously for different isostructural series of complexes. We show here that the parameters obtained from the quantitative analysis of these data can be used to rationalize the observed stability trends across the 4f period. The stability trends along the lanthanide series were also evaluated by calculating the free energy for the reaction [La(L)]n+/−(sol)+Ln3+(sol)→[Ln(L)]n+/−(sol)+La3+(sol). A parameterization of the Ln3+ radii was performed by minimizing the differences between experimental and calculated standard hydration free energies. The calculated stability trends are in good agreement with the experimental stability constants, which increase markedly across the series for BCAED4− complexes, increase smoothly for the TETA4− analogues, and decrease in the case of BP18C62− complexes. The resulting stability trend is the result of a subtle balance between the increased binding energies of the ligand across the lanthanide series, which contribute to an increasing complex stability, and the increase in the absolute values of hydration energies along the 4f period.
