Tubulin alpha 8 (TUBA8) is highly abundant in murine liver tumors suggesting a role in hepatocellular carcinoma (HCC). Non-alcoholic steatohepatitis (NASH) is a risk factor for HCC. In mice that are fed with a methionine-choline deficient diet for two weeks to induce advanced murine NASH, we do see increased hepatic levels of TUBA8 protein. In animals given a high-fat diet for 14 weeks or an atherogenic diet for 12 weeks, hepatic TUBA8 is unchanged. TUBA8 is highly expressed in human hepatic stellate cells (HSC) and co-localizes with the HSC marker desmin in the murine liver...

REVIEW
Fatiha Nassir, Jamal A Ibdah
Mammalian sirtuins are seven members belonging to the silent information regulator 2 family, a group of Class III histone/protein deacetylases. Sirtuins (SIRT 1-7) have different subcellular localization and function and they regulate cellular protein function through various posttranslational modifications. SIRT1 and 3, the most studied sirtuins, use the product of cellular metabolism nicotinamide adenine dinucleotide as a cofactor to post-translationally deacetylate cellular proteins and consequently link the metabolic status of the cell to protein function...

Long-term alcohol stimulation may inhibit the expression of silent information regulator 1 in hepatocytes, which increases the acetylation level of forkhead box transcription factor O1, reduces nuclear localization, and reduces the binding capacity of DNA sequence. This further downregulates the expression of downstream adiponectin receptor 2 and microsomal triglyceride transfer protein, causes lipid metabolism disorders and triglyceride deposition in hepatocytes by affecting adiponectin signal transduction and synthesis of very-low-density lipoprotein, and finally promotes the development of alcoholic fatty liver disease...

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in the developed world and its pathogenesis is complex and multifactorial. It is considered the hepatic manifestation of the metabolic syndrome and is the leading cause of hepatic cirrhosis. This review aims to present current knowledge on the involvement of the adrenal glands in the development of NAFLD. Clinical and animal studies have shown that excess glucocorticoids (GC) have been implicated in the pathogenesis of NAFLD. Patients with NAFLD seem to have a subtle chronic activation of the hypothalamic pituitary adrenal axis leading to a state of subclinical hypercortisolism...

Cellular homeostasis of S-nitrosoglutathione (GSNO), a major cache of nitric oxide bioactivity in plants, is controlled by the NADH-dependent S-nitrosoglutathione reductase (GSNOR) belonging to the family of class III alcohol dehydrogenases (EC 1.1.1.1). GSNOR is a key regulator of S-nitrosothiol metabolism and is involved in plant responses to abiotic and biotic stresses. This study was focused on GSNOR from two important crop plants, cauliflower (Brassica oleracea var. botrytis, BoGSNOR) and lettuce (Lactuca sativa, LsGSNOR)...

Human aldo-keto reductases (AKRs) are NAD(P)H-dependent oxidoreductases that convert aldehydes and ketones to primary and secondary alcohols for subsequent conjugation reactions and can be referred to as "phase 1" enzymes. Among all the human genes regulated by the Keap1/Nrf2 pathway, they are consistently the most overexpressed in response to Nrf2 activators. Although these enzymes play clear cytoprotective roles and deal effectively with carbonyl stress, their upregulation by the Keap1/Nrf2 pathway also has a potential dark-side, which can lead to chemotherapeutic drug resistance and the metabolic activation of lung carcinogens (e...

: The corticotropin releasing factor (CRF) system in the central amygdala (CeA) has been implicated in the effects of acute ethanol and the development of alcohol dependence. We previously demonstrated that CRF receptor 1 (CRF1) neurons comprise a specific component of the CeA microcircuitry that is selectively engaged by acute ethanol. To investigate the impact of chronic ethanol exposure on inhibitory signaling in CRF1+ CeA neurons, we used CRF1:GFP mice subjected to chronic intermittent ethanol (CIE) inhalation and examined changes in local inhibitory control, the effects of acute ethanol, and the output of these neurons from the CeA...

Alcoholic liver disease is a pathological condition caused by overconsumption of alcohol. Because of the high morbidity and mortality associated with this disease, there remains a need to elucidate the molecular mechanisms underlying its etiology and to develop new treatments. Because peroxisome proliferator-activated receptor-β/δ (PPARβ/δ) modulates ethanol-induced hepatic effects, the present study examined alterations in gene expression that may contribute to this disease. Chronic ethanol treatment causes increased hepatic CYP2B10 expression inPparβ/δ(+/+) mice but not in Pparβ/δ(-/-) mice...

Fetal alcohol spectrum disorders (FASD) are present across countries and cultures, with prevalence rates threatening to rise in the coming years. In order to support children and families with FASD around the world, researchers must work to disseminate and implement evidence-based interventions. However, each cultural context presents unique elements and barriers to the implementation process. This review considers the challenges of addressing FASD in an international context. It summarizes existing FASD interventions that have empirical support in the domains of parenting and education, attention and self-regulation, adaptive functioning, and nutrition and medication...

Rutile-monoclinic phase transitions of vanadium oxide (VO2) nanocrystals adsorbed on graphene-based substrates are of current scientific interest, although their adsorption and growth mechanisms have not been investigated theoretically. In this study, we use density functional theory (DFT) calculations for determining the binding energies and predicting the corresponding directions of growth of VO2 nanostructures (rutile and M1-monoclinic) interacting with both pure graphene and functionalized graphene nanoribbons...

Globally, 49% of deaths from traffic crashes occur among vulnerable road users, including pedestrians, bicyclists, and motorcyclists. Approximately, a quarter of those killed are motorcyclists. The authors carried out a systematic review of the literature to evaluate the effectiveness of interventions to prevent motorcycle crashes and the associated morbidity and mortality. The studies included in this review provide evidence for the effectiveness of helmet use, protective clothing, training, and penalties for alcohol consumption and speeding in preventing injury and death to motorcyclists...

REV-ERBα (encoded by Nr1d1) is a nuclear receptor that is part of the circadian clock mechanism and regulates metabolism and inflammatory processes. The glucocorticoid receptor (GR, encoded by Nr3c1) influences similar processes, but is not part of the circadian clock, although glucocorticoid signaling affects resetting of the circadian clock in peripheral tissues. Because of their similar impact on physiological processes, we studied the interplay between these two nuclear receptors. We found that REV-ERBα binds to the C-terminal portion and GR to the N-terminal portion of HSP90α and HSP90β, a chaperone responsible for the activation of proteins to ensure survival of a cell...

Prolyl isomerases are divided into three groups, the FKBP family, Cyclophilin and the Parvulin family (Pin1 and Par14). Among these isomerases, Pin1 is a unique prolyl isomerase binding to the motif including pSer/pThr-Pro that is phosphorylated by kinases. Once bound, Pin1 modulates the enzymatic activity, protein stability or subcellular localization of target proteins by changing the cis- and trans-formations of proline. Several studies have examined the roles of Pin1 in the pathogenesis of cancers and Alzheimer's disease...

Type 5 metabotropic glutamate receptors (mGluR5) activate protein kinase C (PKC) via coupling to Gαq/11 protein signaling. We have previously demonstrated that the epsilon isoform of PKC (PKCɛ) is a critical downstream target of mGluR5 in regulating behavioral and biochemical responses to alcohol. Recent evidence suggests that PKC-mediated phosphorylation of mGluR5 can lead to receptor desensitization and internalization. We therefore sought to examine the specific involvement of PKCɛ in the regulation of mGluR5 surface expression in the nucleus accumbens (NAc), a key regulator of alcohol-associated behaviors...

BACKGROUND: Favourable impacts are reported from complex alcohol control strategies, known as 'Alcohol Management Plans' (AMPs) implemented 14 years ago in 19 Aboriginal and Torres Strait Islander (Indigenous) communities in Queensland (Australia). However, it is not clear that all communities benefited and that positive impacts were sustained. Service providers, key stakeholders and community leaders provided insights about issues and impacts. METHODS: Participants (N=382) were recruited from knowledgeable and experienced persons using agency lists and by recommendation across sectors which have a mandate for managing alcohol-related issues and consequences of AMP policies in communities...

A plant cuticle forms a hydrophobic layer covering plant organs, and plays an important role in plant development and protection from environmental stresses. We examined epicuticular structure, composition, and a MYB-based regulatory network in two Australian wheat cultivars, RAC875 and Kukri, with contrasting cuticle appearance (glaucousness) and drought tolerance. Metabolomics and microscopic analyses of epicuticular waxes revealed that the content of β-diketones was the major compositional and structural difference between RAC875 and Kukri...
