“Essential hypertension is a multifactorial disease, considered to be one of the world’s greatest public health problems. Despite recent, major, technical advances aiming to elucidate its genetic component, the discovered biomarkers up to now were reported to have only small effects, explaining consequently a tiny fraction of its phenotypic variance and resulting in a large proportion of missing heritability. Likewise, little evidence is available with regard
to the epigenetic regulation of essential hypertension, since no robust biomarkers have yet been reported.\n\nIn the current review, we discuss the main approaches used exclusively to study the genetics and epigenetics of essential hypertension, the HDAC inhibitor biomarkers
identified, their clinical utility and the difficulties to be overcome. Furthermore, we propose a new category of functional genetic-epigenetic biomarkers, eMethSNPs, and we provide their hypothetical gene expression profiles for a genetic functional regulation of hypertension via DNA methylation. Though believed to be infrequent, eMethSNPs could constitute a new category of mechanistically-based genetic biomarkers predisposing to essential hypertension. (C) 2012 Elsevier B.V.

“The nuclear receptor peroxisome proliferator-activated receptor-gamma (PPAR gamma) has important roles in adipogenesis and immune response as well as roles in both lipid and carbohydrate metabolism. Although synthetic agonists for PPAR gamma
are widely used as insulin sensitizers, the identity of the natural ligand(s) for PPAR gamma is still not clear. Suggested natural ligands include 15-deoxy-Delta(12,14)-prostaglandin GM6001 J2 and oxidized fatty acids such as 9-HODE and 13-HODE. Crystal structures of PPAR gamma have revealed the mode of recognition for synthetic compounds. Here we report structures of PPAR gamma bound to oxidized fatty acids that are likely to be natural ligands for this receptor. These structures reveal that the receptor can (i) simultaneously bind two fatty acids and (ii) couple covalently with conjugated oxo fatty acids. Thermal stability and gene expression analyses suggest that such covalent ligands are particularly effective activators of PPAR gamma and thus may serve as potent and biologically relevant ligands.”
“External climate forcings-such as long-term changes in solar insolation-generate different climate responses in tropical and high latitude regions(1). Documenting the spatial and temporal variability of past climates is therefore critical for understanding how such forcings are translated into regional climate variability.
Migrations were often precipitated by household shocks due to changes in marital status (as when widowhood resulted in disinheritance) and gender-based violence. Many migrants engaged in transactional sex, of varying
regularity, from clandestine to overt, to supplement earnings from informal sector trading. Migrant women are at high risk of HIV transmission and acquisition: the circumstances that drove migration may have also increased HIV infection risk at origin; and social contexts in destinations facilitate having multiple sexual partners and engaging in transactional sex. We propose a model for understanding the pathways through which migration contributes to HIV risks in women in high HIV prevalence areas in Africa, highlighting potential opportunities for primary and secondary HIV prevention at origins and destinations, and at key ‘moments of vulnerability’ in the migration process.

Cell Cycle inhibitor Most treatment guidelines for acne are based on clinical severity. Our objective was to expand that approach to one that also comprised individualized patient features: a case-based approach. Methods: An expert panel of Canadian dermatologists was established to develop demographic and clinical features considered to be particularly important in acne treatment selection. A nominal group consensus process JQ1 Epigenetics inhibitor was used for inclusion of features and corresponding appropriate treatments. Results: Consensus was achieved on the following statements: follicular epithelial dysfunction contributes to acne pathogenesis; inflammation from underlying disease(s) or prior treatment may impact further patient management; management focusing on specific patient features and on addressing psychosocial factors, including impact on quality of life, may improve treatment adherence and outcomes; and case-based scenarios are a practical approach to illustrate the effect of these factors. To address the https://www.selleckchem.com/products/ON-01910.html latter, eight case profiles were developed. Conclusions: Management of acne should
be based on multifactorial considerations beyond clinically determined acne severity and should include patient-reported impact, gender, skin sensitivity (including preexisting dermatoses), and phototype.”
“BackgroundAdeno-associated virus (AAV) vectors are used to deliver potentially therapeutic genes in clinical trials in Parkinson’s disease (PD). Pre-existing immunity to AAV and a local neuroinflammatory response might negatively affect the efficacy of such AAV-mediated gene delivery. MethodsWe pre-immunized rats with wild-type AAV-2. Three months later, we created PD-like lesions by intrastriatal injections of 6-hydroxydopamine (6-OHDA) in 50% of the animals. One month later, we injected AAV2 vector expressing enhanced green fluorescent protein (eGFP) in the striatum. Using immunohistochemistry, we assessed eGFP expression, microglia activation and CD8 T cell infiltration.
The complete mitochondrial (mt) genome of M. baileyi has been determined. Our results showed that the total length of the mitogenome was 16,351 bp, and had a gene content of 13 protein coding, 22 tRNAs and 2 rRNAs. Except for the seven tRNA and Nd6 genes, all other mt genes are encoded on the heavy strand. The overall base composition of the heavy strand is 33.65% A, 29.65% T, 24.42% C, and 12.28% G, with an AT content of 63.3%.”
“Exponential-phase yeast cells readily enter stationary
phase when transferred to fresh, carbon-deficient medium, and can remain fully viable for up to several months. It is known that stationary-phase prokaryotic cells may still synthesize substantial amounts of DNA. Although the basis of this phenomenon remains check details unclear, this DNA synthesis may be the result of DNA maintenance and repair, recombination, and stress-induced transposition of mobile elements, which may occur in the absence of DNA replication. To the best of our knowledge, the existence of DNA turnover in stationary-phase unicellular eukaryotes remains largely unstudied. By performing cDNA-spotted (i.e. ORF) microarray analysis of stationary cultures of a haploid Saccharomyces cerevisiae strain, we demonstrated on a genomic scale the localization of a DNA-turnover marker [5-bromo-2'-deoxyuridine (BrdU); an analogue of thymidine], Selleck Tariquidar indicative of DNA synthesis in discrete,
multiple sites across the genome. Exponential-phase cells on the other hand, exhibited a uniform, total genomic DNA synthesis pattern, possibly the result of DNA replication. Interestingly, BrdU-labelled sites exhibited a significant overlap with highly expressed features. We also found that the distribution among chromosomes of BrdU-labelled and expressed features deviates from random distribution; this was also observed for the overlapping set. Ty1 retrotransposon genes were also found to be labelled with BrdU, evidence for transposition during stationary phase; however, they were not significantly expressed. We discuss the relevance and possible connection of these
results to DNA repair, mutation and SB273005 ic50 related phenomena in higher eukaryotes.”
“Mitochondrial DNA mutations and associated defects in cytochrome c oxidase (COX) are proposed to play an important role in human ageing; however there have been limited studies on the frequency of these defects in normal mouse ageing. Here we compare COX-deficiency in two epithelial tissues; the colon and the ciliary epithelium, from human and mouse. The pattern of accumulation of COX-deficiency is similar in both tissues in the two species; however the frequency of colonic crypts with COX-deficiency in aged humans is significantly higher than in aged mice, whereas the levels of COX-deficiency in the ciliary epithelium are higher in the mouse than in humans.
“Nuclear uptake of the simian virus (SV) 40 T antigen is triggered by a specific nuclear localization sequence. However, such a nuclear localization sequence is only poorly taken up by the cytoplasm of cells when administered to the culture medium. Our aim was to improve the cytoplasmic uptake of the SV 40 T antigen nuclear localization https://www.selleckchem.com/products/BI6727-Volasertib.html sequence. Consequently, we synthesized novel
fluorescein isothiocyanate-labelled conjugates containing the nuclear localization sequences of the SV 40 T antigen and either trichlorobenzoic or trifluorobenzoic acid. Applied at 260 mu m such halogenated NLS conjugates were nuclearly taken up by 75-85% of U373 and LN18 glioma cells and resulted in cell death. Nuclear staining and cell death were also found at lower concentrations (130 and 65 mu m) of halogenated nuclear localization sequence conjugates. By contrast only a low cellular staining rate and no cell death could be observed after co-incubation with a trichlorobenzoic acid or trifluorobenzoic acid-lacking nuclear localization sequence conjugate and free, unbound trichlorobenzoic acid or trifluorobenzoic acid at the high concentration (260 mu m). Such small non-radioactive fluorinated
and chlorinated nuclear localization sequences may be used as important components for future antiglioma drug development.”
“Background: Telomere length, an indicator of ageing and longevity, has been correlated with several biomarkers of cardiometabolic disease in both Arab children and adults. It is not known, however, whether or not telomere Z-DEVD-FMK datasheet length is a highly conserved inheritable trait in this homogeneous cohort, where age-related diseases are highly prevalent. As such, the aim of this study was to address the inheritability of telomere length in
Saudi families and the impact of cardiometabolic disease biomarkers on telomere length.\n\nMethods: selleck chemical A total of 119 randomly selected Saudi families (123 adults and 131 children) were included in this cross-sectional study. Anthropometrics were obtained and fasting blood samples were taken for routine analyses of fasting glucose and lipid profile. Leukocyte telomere length was determined using quantitative real time PCR.\n\nResults: Telomere length was highly heritable as assessed by a parent-offspring regression [h2 = 0.64 (p = 0.0006)]. Telomere length was modestly associated with BMI (R-2 0.07; p-value 0.0087), total cholesterol (R-2 0.08; p-value 0.0033), and LDL-cholesterol (R-2 0.15; p-value 3 x 10(-5)) after adjustments for gender, age and age within generation.\n\nConclusion: The high heritability of telomere length in Arab families, and the associations of telomere length with various cardiometabolic parameters suggest heritable genetic fetal and/or epigenetic influences on the early predisposition of Arab children to age-related diseases and accelerated ageing.
5 Hz), alpha (8-12.5 Torin 2 Hz), and beta (13-30 Hz) frequency bands; spectral edge frequency; and mean dominant frequency. Results. -The use of wool cap had no effect on all electroencephalogram parameters considered. Gestational age showed an effect on relative spectral power of all considered bands, spectral edge frequency and mean dominant frequency, while no effect was seen on burst
suppression ratio and asymmetry index. Neonates born at gestational weeks lower than 28 had significantly higher relative power in the 6 band and lower relative power in the alpha and beta bands. Conclusions. -Heat loss prevention using wool cap does not affect interpretation of spectral electroencephalogram. Spectral values AZD5153 ic50 in our group of very premature infants without neurological complications correspond to normal data reported in the literature. Maturation changes consist of reduction of relative power of the delta band, spectral edge frequency and mean dominant frequency. (C) 2014 Elsevier Masson SAS. All rights reserved.”
“Background: The Drosophila neoplastic tumor suppressor Lethal (2) giant larvae (Lgl) controls apicobasal cell polarity and proliferation. We have previously shown that lgl(-) clones in the developing eye exhibit ectopic proliferation and suppress apoptosis without affecting apicobasal cell polarity. Ectopic expression of the apical polarity regulators atypical
protein kinase C (aPKC) and Crumbs also leads to increased cell proliferation and/or survival. Here we investigate how these cell polarity regulators control proliferation and survival.\n\nResults: We report that depletion of lgl in eye epithelial tissue, where polarity is maintained, results in upregulation of targets of the Salvador/Warts/Hippo (SWH) tumor suppressor pathway.
Consistent with this, the SWH pathway transcriptional coactivator Yorkie is hyperactivated in Lgl-deficient tissue and is rate CHIR-99021 datasheet limiting for lgl(-) phenotypes. Overexpression of the apical polarity regulators Crumbs or aPKC also leads to ectopic expression of SWH pathway targets without affecting polarity. We show that Lgl depletion or aPKC overexpression results in comislocalization of Hippo and Ras-associated domain family protein (RASSF), consistent with RASSF’s ability to block Hippo activation by Salvador. In contrast, Crumbs overexpression leads to mislocalization of Expanded away from the apical cortex, which is predicted to deregulate the pathway.\n\nConclusions: Collectively, our data reveal that the cell polarity regulators Lgl, aPKC, and Crumbs regulate the SWH pathway by two distinct pathways: Lgl acts antagonistically to aPKC to regulate Hippo and RASSF localization, whereas Crumbs regulates Expanded localization. Thus, our study implicates Lgl, aPKC, and Crumbs as regulators of tissue growth via the SWH pathway.”

“Background. Programmed death-1 ligand-1 (PD-L1, CD274, B7-H1) has been identified as the ligand for the immunoinhibitory receptor Selleckchem STI571 programmed death-1 and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. In this study, we tested the effect of PD-L1-transfected pancreatic beta-cell line established from a transgenic NDD/Lt mouse (NIT) on the alloresponse
and streptozotocin-induced diabetes.\n\nMethods. The diabetes model was established by a low dose of streptozotocin in Balb/C mice. PD-L1 transfected NIT cell line was established, namely NIT-PD-L1. NIT-1, empty vector-transfected NIT-1, or NIT-PD-L1 cells were transplanted into diabetic mice by intraperitoneal injection, respectively. Proliferation and apoptosis of splenic lymphocytes were detected by labeling with carboxy fluoroscein succinimidyl ester or AnnexinV-Cy5 and proliferation index (PI). Cytokines were determined by enzyme-linked immunosorbent assay and flow cytometry analysis.\n\nResults. When compared with the controls,
overexpression of PD-L1 on NIT-1 cells markedly prolonged allograft survival in diabetic mice. In mixed cells reaction, splenic lymphocytes Doramapimod in vitro from NIT-PD-L1-transplanted diabetic mice co-culture with mitomycin C-treated NIT-PD-L1 showed the lowest proliferative response but severe apoptosis. Ricolinostat purchase In addition, NIT-PD-L1 Suppressed interferon-gamma but up-regulated interleukin-4 and -10 productions by those lymphocytes in vitro and in vivo.\n\nConclusion.
Our data demonstrated that overexpression of PD-L1 on pancreatic beta cells significantly can prolong allograft survival, and it is associated with inhibition of lymphocytes activation and proliferation, induction of lymphocytes apoptosis.”
“Background: Lung cancer is the leading cause of cancer death and a major public health challenge across the entire world. Computed tomography (CT) imaging of the lung is a rapidly improving medical imaging technique. Spiral CT has been reported to not only improve the early detection of lung cancer in screening high-risk tobacco-exposed populations but also to assist in the clinical assessment of new agents for therapy in lung cancer.\n\nMethods: The Prevent Cancer Foundation has sponsored a series of workshops to accelerate progress in using quantitative imaging to advance lung cancer research progress, of which this report summarizes the Ninth Workshop. The defining strategy of this forum to support innovation in quantitative research for early lung cancer management was to enable software validations by assembling collections of high-quality images for which long-term clinical follow-up is known. An additional approach was to define a process for high-quality and economical national implementation of lung cancer screening.
Furthermore, the first sAA increase was associated with task induced deactivation (TID) in frontal and parietal regions. However, these effects were restricted to the first part of the experiment. Consequently, this bias of scanner related sympathetic activation should be considered in future fMRI investigations.
It is of particular importance for pharmacological investigations studying adrenergic agents and the comparison of groups with different stress vulnerabilities like patients and controls or adolescents and adults.”
“Evidence shows that febrile convulsions induced in rat pups increase ultrasonic vocalizations (USVs); however, the effect of status epilepticus (SE) induced in developing rats on USVs has not been fully investigated. The goal of this study
was to analyze USVs following lithium-pilocarpine-induced SE in Silmitasertib nmr fourteen-day-old (P14) rat pups. The rat pups were given 3-mEq/kg lithium chloride i. p. on selleck chemicals the day before the induction of SE, which was carried out at P14 by subcutaneous injection of 100-mg/kg pilocarpine hydrochloride; control animals were given an equal volume of lithium chloride and saline on P13 and P14, respectively. Ultrasonic vocalizations were monitored at P15, P16, and P21 with a Mini 3 Bat Detector Ultra Sound Advice (15 kHz-160 kHz) set at 40 +/- 4 kHz and digitally recorded in WAV format using the Audacity 1.3 beta software. A clear box (60x40x30cm) split down the middle with a holedwall was used; each pup was placed alone in one compartment, whereas its dam was placed on the other cage side at room temperature. Vocalizations were recorded over a 5-minute period, converted to sonograms and spectrograms, and analyzed using the Raven software. Parameters phosphatase inhibitor library evaluated were as
follows: USV frequency, latency to the first USV, and mean USV duration. There was a significant decrease in the latency (35.5 +/- 6.9 s) and duration (50.8 +/- 8.6 s) of USVs after SE compared with the control group (81.9 +/- 10.8 s and 78.1 +/- 9.9 s, respectively). Status epilepticus affected male and female rats differentially. (C) 2013 Elsevier Inc. All rights reserved.”
“Introduction: Recent improvements in alloys, kinematics, and concepts have been combined to increase the cyclic fatigue resistance of nickel-titanium (NiTi) instruments. The aim of this study was to compare the cyclic fatigue resistance of new M-Wire reciprocating WaveOne (Dentsply Maillefer, Ballaigues, Switzerland) and Reciproc (VDW GmbH, Munich, Germany) files at 2 levels. Methods: Sixty Reciproc and 60 WaveOne new files were fixed to a specifically designed device and tested in tempered steel canals with a 3-mm radius and a 600 angle of curvature. The motor used was programmed as defined by each manufacturer, and the specific reciprocating motion was followed. Thirty files of each brand were tested at 5 mm, and 30 were tested at 13 mm from their tips. The time to failure was registered.
The model evaluated as the most suitable used the covariance function of fourth
order to describe the variability of the effects of additive genetic, animal permanent environmental and maternal effects of third order to describe the maternal genetic effect, with four classes of residual variance. Heritability estimates ranged from 0.18 to 0.46 from the beginning of trajectory to 210 days of age, from 0.45 to 0.48 post-weaning GDC-0973 datasheet to 365 days of age and from 0.47 to 0.57 at later ages. The values of additive genetic correlations for different ages showed higher estimates between the closest ages, while birth weight was not very related to the weights at older ages. The body weight performance of the animals has additive genetic variation to respond to selection.”
“1. Large areas of alpine pastures and meadows currently face declining land use or abandonment, which leads to tall-grass transition ecosystems with higher leaf area index (LAI), potentially increased evapotranspiration (ET) and thus, reduced water yield. Elevated atmospheric CO2, on the other hand, is known to reduce stomata opening and hence, leaf-level transpiration, which may translate into higher soil moisture and enhanced total runoff. Here, we quantify these opposing effects Pitavastatin inhibitor of global change on the water balance of alpine grassland in a field experiment in the Swiss Alps (2440 m a.s.l.).\n\n2. Rates of ET and deep seepage (percolation
water) of four alpine grassland types (dominated by Agrostis, Nardus, Carex or forbs) were measured using intact monoliths in 51 weighing lysimeters. A part of the monoliths was clipped to simulate sheep grazing during three seasons (2008-2010). Another set was exposed to elevated CO2 (580 ppm) using free-air CO2 enrichment selleck inhibitor (FACE) during the 2009 growing season.\n\n3. Simulated grazing reduced bright day ET by on average -12% across all years, with the most pronounced effects in the high-stature swards. Correspondingly, the higher biomass and LAI in unclipped grassland lowered the seasonal
sum of deep seepage by -13% in a drier summer (2009) and by -5% in a rather wet summer (2010) compared to clipped swards.\n\n4. CO2 enrichment reduced ET in all grassland types by -3 to -7%, increased delta O-18 in foliage and enhanced soil moisture, but not deep seepage. Hence, future CO2 slightly counteracts the land use effects at canopy level, however, not in terms of water yield.\n\n5. Synthesis. Our results indicate that both grazing and elevated CO2 are mitigating the effects of dry spells on alpine vegetation. The net effect of the continuous decline in the land use and of elevated CO2 is negative for catchment water yield and thus, for potential hydroelectric power production. Although these economic ‘costs’ are rather moderate per hectare of alpine grassland, sums are substantial when scaled to the vast areas potentially affected in the Alps.
The physical properties of paclitaxel (PTX)-loaded poly(lactic-co-glycolic acid) (PLGA) inks, such as volatility, viscosity and surface tension, were optimized for piezoelectric inkjet printing, and PTX-loaded PLGA microparticles were fabricated with various geometries, such as circles, grids,
honeycombs, and rings. The resulting microparticles with 10% (w/w) PTX exhibited a fairly homogeneous shape and size. The microparticle fabrication by piezoelectric inkjet printing was precise, reproducible, and highly favorable for mass production. The microparticles exhibited a biphasic release profile with an initial burst due to diffusion and a subsequent, slow second phase due to degradation of PLGA. The release rate was dependent on the geometry, ATM inhibitor mainly the surface area, with a descending rate order of honeycomb > grid, ring > circle. The PTX-loaded microparticles showed SNS-032 Cell Cycle inhibitor a comparable activity in inhibiting the growth of HeLa cells. Our results demonstrate that a piezoelectric inkjet printing system would provide a new approach for large-scale manufacturing of drug carriers with a desired geometry. (C) 2012 Elsevier B.V.

“G protein-coupled receptors (GPCRs) are integral membrane proteins that change conformation after ligand binding so that they can transduce signals from an extracellular ligand to a variety of intracellular components.
The detailed interaction of a molecule with a G protein-coupled receptor is a complicated process that is influenced by the receptor conformation, thermodynamics, and ligand conformation and stereoisomeric configuration. To better understand the molecular interactions
of fenoterol analogs with the beta(2)-adrenergic receptor, we developed a new agonist radioligand for binding assays. [H-3](R,R’)-methoxyfenoterol was used to probe the binding affinity learn more for a series of fenoterol stereoisomers and derivatives. The results suggest that the radioligand binds with high affinity to an agonist conformation of the receptor, which represents approximately 25% of the total beta(2)-adrenoceptor (AR) population as determined with the antagonist [H-3]CGP-12177. The beta(2)-AR agonists tested in this study have considerably higher affinity for the agonist conformation of the receptor, and K-i values determined for fenoterol analogs model much better the cAMP activity of the beta(2)-AR elicited by these ligands. The thermodynamics of binding are also different when interacting with an agonist conformation, being purely entropy-driven for each fenoterol isomer, rather than a mixture of entropy and enthalpy when the fenoterol isomers binding was determined using [H-3]CGP-12177. Finally, computational modeling identified the molecular interactions involved in agonist binding and allow for the prediction of additional novel beta(2)-AR agonists.
DPF3a and DPF3b are additionally shown to interact directly with RelA, p50, and several subunits of the SWI/SNF complex in vitro and to be co-immunoprecipitated with RelA/p50 and the SWI/SNF complex from the nuclear fractions of cells treated with TNF-alpha. In ChIP experiments, we further found that endogenous DPF3a/b and the SWI/SNF complex are continuously present on HIV-1 LTR, whereas the kinetics of RelA/p50 recruitment after TNF-alpha treatment correlate well with the viral transcriptional activation
levels. Additionally, re-ChIP experiments showed DPF3a/b and the SWI/SNF complex associate with RelA on the endogenous IL-6 promoter after TNF-alpha treatment. In conclusion, our present data indicate that by linking RelA/p50 to the SWI/SNF complex, DPF3a/b induces the transactivation of CBL0137 purchase NF-kappa B target gene promoters in relatively inactive chromatin contexts.”
“Endometrial cancer belongs to the commonest malignancy in females. Its development may be associated with the high exposure of endometrium to exo- and 3-MA inhibitor endogenous estrogens. Estrogens produce DNA bulky adducts and oxidative base damages which are removed in nucleotide excision repair (NER) and base excision repair (BER) pathways. The reaction of endometrial cells to DNA damage may be crucial for their susceptibility to cancer
transformation. This reaction is executed mainly by DNA repair, which can be modulated by the variability in the genes encoding DNA repair proteins. In this report we genotyped 4 polymorphisms of 3 DNA repair genes in 94 endometrial cancer patients and 114 age-matched cancer-free women using RFLP-PCR. The following polymorphisms were studied: p.Arg194Trp, p.Arg399Gln of the XRCC1 Danusertib datasheet gene, p.Ser326Cys of the hOGG1 gene and p.Lys751Gln of the ERCC2 gene. We found an association between the ERCC2 751Gln variant and endometrial cancer occurrence (OR 3.95; 95 % CI 1.88-8.31). Gene-gene interaction between the ERCC2 751Gln and XRCC1 194Trp variants also increased the risk of endometrial cancer (OR 4.41; 95 % CI 2.01-9.67). The risk in the carriers of the ERCC2 751Gln variant was increased by a positive cancer
history in first degree relatives (OR 4.97; 95 % CI 1.98-12.48). The risk of endometrial cancer was not alter by polymorphism p.Ser326Cys of the hOGG1 gene. The 751 Lys/Gln polymorphism of the ERCC2 gene may be linked with endometrial cancer occurrence and its effect can be potentiated by variants of the XRCC1 gene or first degree relatives positive cancer history.”
“The transcription factor nuclear factor-E2-related factor-2 (Nrf2) is a key regulator for induction of hepatic antioxidative stress systems. We aimed to investigate whether activation of Nrf2 protects against steatohepatitis.\n\nWild-type mice (WT), Nrf2 gene-null mice (Nrf2-null) and Keap1 gene-knockdown mice (Keap1-kd), which represent the sustained activation of Nrf2, were fed a methionine- and choline-deficient diet (MCDD) for 13 weeks and analyzed.
