MiR-21 is a microRNA implicated in cancer, development, and cardiovascular diseases and expressed in the central nervous system (CNS), especially after injury. However, the cellular expression of miR-21 in the adult CNS has not been clearly established either in mice or human subjects, while its alteration in psychiatric disorders is unknown. MiR-21 expression was characterized in reporter mice expressing β-galactosidase (LacZ) under the endogenous miR-21 promoter (miR-21/LacZ). Brain co-localization of miR-21/LacZ with specific neural markers was examined by double immunofluorescence in reporter mice, while extent of immunostaining for myelin basic protein and PDGFRα was determined in miR-21 knockout and wild-type mice...

Heterotopic ossification(HO) is a potential severe complication after many biomaterial implanting surgeries, and the inflammation environment caused by the implanting-associated infections is considered as the main nosogenesis. Herein, an inflammation-responsive drug release system was designed by chemically conjugating indometacin (via ester group) onto hydrogel coating to realize local self-regulated drug release to prevent HO. In our strategy, poly(3-mercaptopropyl)trimethoxysilane-co-acrylic acrylate and polyvinyl alcohol (providing anchoring sites for drug molecules) were firstly synthesized and functionalized with ene-groups, then a hydrogel layer was formed and covalently attached onto thiol-modified substrate via thiol-ene click chemistry, followed by grafting indometacin...

Alcohol dehydrogenases (ADH) are key enzymes of ethanol metabolism that mediate its oxidation to acetaldehyde. ADHs are also able to oxidize some types of neurotransmitters such as dopamine, serotonin and norepinephrine. Increased level of ADHs activity, induced by chronic alcohol consumption, is presumably associated with disturbed neurotransmitters metabolism that leads to stable alcohol craving. As earlier reported, intraperitoneal administration of 4-methilpirasole (non-specific inhibitor of ADHs) has shown to provide a short-term anti-alcoholic effect, but individual roles of ADH isoforms in this process were still unclear...

Alcohol use disorder is a devastating illness with a profound health impact, and its development is dependent on both genetic and environmental factors. This disease occurs over time and requires changes in brain gene expression. There is converging evidence suggesting that the epigenetic processes may play a role in the alcohol-induced gene regulations and behavior such as the intervention of DNA methylation and histone acetylation. Histone acetylation, like histone methylation, is a highly dynamic process regulated by two classes of enzymes: histone acetyltransferases and histone deacetylases (HDACs)...

The goal of this study was to analyze the effect of local and state mandatory restaurant menu labeling laws on alcohol use. Using a difference-in-differences estimation approach and data on adults aged 21 and older (n=2,157,722) from the 2002-2012 Behavioral Risk Factor Surveillance System, we estimated the effect of menu labeling laws on self-reported consumption of alcoholic beverages in the past month. The regression analysis indicates that on average implementation of menu labeling laws is associated with a 1...

OBJECTIVE: While governments draft law and policy to promote public health, it is through cases put before the judiciary that the implementation of law can be challenged and where its practical implications are typically determined. In this paper, we examine the role of court judgements on efforts in Australia to regulate the harmful use of alcohol. METHODS: Australian case law (2010 to June 2015) involving the judicial review of administrative decisions relating to development applications or liquor licences for retail liquor outlets (bottle shops), hotels, pubs and clubs was identified using a case law database (WestLaw AU)...

The central amygdala (CeA) is involved in the processing of anxiety and stress and plays a role in ethanol consumption. Chronic ethanol recruits stress systems in the CeA, leading to aversive withdrawal symptoms. Although primarily GABAergic, CeA contains glutamatergic afferents, and we have reported inhibitory effects of ethanol on locally evoked glutamatergic responses in CeA of Wistar and Marchigian Sardinian alcohol-preferring (msP) rats. Notably, msP rats display enhanced anxiety, stress and alcohol drinking, simulating the alcohol-dependent phenotype...

ETHNOPHARMACOLOGICAL RELEVANCE: Gangjihwan (DF), a polyherbal drug composed of Ephedra intermedia Schrenk et C. A. Mayer (Ephedraceae), Lithospermum erythrorhizon Siebold et Zuccarini (Borraginaceae), and Rheum palmatum L. (Polygonaceae), is used to treat obesity in local Korean clinics. The constituents of DF have traditionally been reported to exert anti-obesity and anti-nonalcoholic fatty liver disease (NAFLD) effects. Thus, we investigated the effects of DF on obesity and NAFLD and the underlying mechanisms...

Chemokine (CC-motif) receptor-like 2 (CCRL2) is a decoy receptor and regulates the local responses of the chemokine chemerin. Recently our group has shown that the functional chemerin receptor, chemokine-like receptor 1 (CMKLR1), correlates with fibrosis and non-alcoholic steatohepatitis (NASH) score in males only. In our current study, we wanted to know whether CCRL2 shows similar correlations as CMKLR1. Therefore, we analyzed the hepatic expression of CCRL2 in murine NASH and in liver tissues obtained from 85 patients with non-alcoholic fatty liver disease (NAFLD) and 33 controls...

The pathogenesis of non-alcoholic steatohepatitis (NASH) is still unclear and the prevention of the development of hepatocellular carcinoma (HCC) has not been established. We established an atherogenic and high-fat diet mouse model that develops hepatic steatosis, inflammation, fibrosis, and liver tumors at a high frequency. Using two NASH-HCC mouse models, we showed that peretinoin, an acyclic retinoid, significantly improved liver histology and reduced the incidence of liver tumors. Interestingly, we found that peretinoin induced autophagy in the liver of mice, which was characterized by the increased co-localized expression of microtubule-associated protein light chain 3B-II and lysosome-associated membrane protein 2, and increased autophagosome formation and autophagy flux in the liver...

REVIEW
Hye-Kyung Na, Ja Young Lee
Many meta-analysis, large cohort studies, and experimental studies suggest that chronic alcohol consumption increases the risk of gastric and colon cancer. Ethanol is metabolized by alcohol dehydrogenases (ADH), catalase or cytochrome P450 2E1 (CYP2E1) to acetaldehyde, which is then further oxidized to acetate by aldehyde dehydrogenase (ALDH). Acetaldehyde has been classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen to humans. The acetaldehyde level in the stomach and colon is locally influenced by gastric colonization by Helicobacter pylori or colonic microbes, as well as polymorphisms in the genes encoding tissue alcohol metabolizing enzymes, especially ALDH2...

Nigeria has high levels of alcohol consumption, and little or no regulation of the alcohol industry. There is a dearth of studies exploring young adults' drinking in a Nigerian context with only a few predominantly quantitative surveys. These do not explore the social meanings attached to drinking practices nor do they shed light on potential gender differences and how these are mediated by popular media. This qualitative study addresses this gap with semi-structured interviews involving 31 undergraduate students...

Alcohol has a profound effect on sleep. However, neuronal substrates mediating sleep-promoting effects of alcohol are unknown. Since the basal forebrain (BF) cholinergic neurons are implicated in the homeostatic regulation of sleep, we hypothesized that the BF cholinergic neurons may have an important role in sleepiness observed after alcohol consumption. 192-IgG-saporin (bilateral BF infusions) was used to selectively lesion BF cholinergic neurons in adult male Sprague Dawley rats. Standard surgical procedures were used to implant sleep recording electrodes or microdialysis guide cannulas...

Midkine (MDK) is a cytokine and neurotrophic factor that is more highly expressed in the brains of alcoholics and in mice predisposed to drink large amounts of ethanol, suggesting that MDK may regulate ethanol consumption. Here we measured ethanol consumption in male and female Mdk knockout (-/-) mice using the two-bottle choice and the drinking in the dark (DID) tests. We found that Mdk -/- mice consumed significantly more ethanol than wild-type controls in both tests. To determine if MDK acts in the ventral tegmental area (VTA) to regulate ethanol consumption, we delivered lentivirus expressing a Mdk shRNA into the VTA of male C57BL/6J mice to locally knockdown Mdk and performed the DID test...

Alcohol use disorders (AUDs) and anxiety disorders (ADs) are often seen concurrently, but their underlying cellular basis is unclear. For unclear reasons, the lateral habenula (LHb), a key brain region involved in the pathophysiology of ADs, becomes hyperactive after ethanol withdrawal. M-type K(+) channels (M-channels), important regulators of neuronal activity, are abundant in the LHb, yet little is known about their role in AUDs and associated ADs. We report here that in rats at 24 h withdrawal from systemic ethanol administration (either by intraperitoneal injection, 2 g/kg, twice/day, for 7 days; or intermittent drinking 20% ethanol in a two-bottle free choice protocol for 8 weeks), the basal firing rate and the excitability of LHb neurons in brain slices was higher, whereas the amplitude of medium afterhyperpolarization and M-type K(+) currents were smaller, when compared to ethanol naive rats...

Recruitment of inflammatory cells is a major feature of alcoholic liver injury however; the signals and cellular sources regulating this are not well defined. C-C chemokine receptor type 2 (CCR2) is expressed by active hepatic stellate cells (HSC) and is a key monocyte recruitment signal. Activated HSC are also important sources of hydrogen peroxide resulting from the activation of NADPH oxidase 4 (NOX4). As the role of this NOX in early alcoholic liver injury has not been addressed, we studied NOX4-mediated regulation of CCR2/CCL2 mRNA stability...

Abnormal lipid-mediated hepatic inflammatory-immune dysfunction and chronic low grade inflammation play an important role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). Macrophage polarization is an important mechanism for the regulation of inflammatory response. Since PPAR-γ has emerged as a master regulator of macrophage polarization, we aimed to investigate the lipid-induced macrophage/Kupffer cell polarization in vivo and in vitro, and explore the association between PPAR-γ activity and macrophages M1/M2 polarization shifting...

The astringency of Chinese pollination-constant non-astringent (C-PCNA) persimmon (Diospyros kaki Thunb.) can be naturally removed on the tree. This process is controlled by a single locus and is dominant against other types of persimmons; therefore, this variant is an important candidate for commercial cultivation and the breeding of PCNA cultivars. In our previous study, six full-length coding sequences (CDS) for pyruvate kinase genes (DkPK1-6) were isolated, and DkPK1 is thought to be involved in the natural deastringency of C-PCNA persimmon fruit...
