[Q]: Alcoholic liver disease (ALD) ranges from fatty liver to inflammation and cirrhosis. miRNA-155 is an important regulator of inflammation. In this study, we describe the in vivo role of miR-155 in ALD.', 'Wild-type (WT) (C57/BL6J) or miR-155 knockout (KO) and TLR4 KO mice received Lieber DeCarli diet for 5weeks. Some mice received corn oil or CCl4 for 2 or 9weeks.', 'We found that miR-155 KO mice are protected from alcohol-induced steatosis and inflammation. The reduction in alcohol-induced fat accumulation in miR-155 KO mice was associated with increased peroxisome proliferator-activated receptor response element (PPRE) and peroxisome proliferator-activated receptors (PPAR) (miR-155 target) binding and decreased MCP1 production. Treatment with a miR-155 inhibitor increased PPAR expression in naive and alcohol treated RAW macrophages. Alcohol increased lipid metabolism gene expression (FABP4, LXR, ACC1 and LDLR) in WT mice and this was prevented in KO mice. Alcohol diet caused an increase in the number of CD163(+) CD206(+) infiltrating macrophages and neutrophils in WT mice, which was prevented in miR-155 KO mice. Kupffer cells isolated from miR-155 KO mice exhibited predominance of M2 phenotype when exposed to M1 polarized signals and this was due to increased C/EBP. Pro-fibrotic genes were attenuated in miR-155 KO mice after alcohol diet or CCl4 treatment. Compared to WT mice, attenuation in CCl4 induced hydroxyproline and -SMA was observed in KO mice. Finally, we show TLR4 signaling regulates miR-155 as TLR4 KO mice showed no induction of miR-155 after alcohol diet.

[Q]: The objective of this study is to characterize differential proteomic expression among well-differentiation and poor-differentiation colorectal carcinoma tissues and normal mucous epithelium.', 'The study is based on quantitative 2-dimensional gel electrophoresis and analyzed by PDquest.', 'Excluding redundancies due to proteolysis and posttranslational modified isoforms of over 600 protein spots, 11 proteins were revealed as regulated with statistical variance being within the 95th confidence level and were identified by peptide mass fingerprinting in matrix assisted laser desorption/ionization time-of-flight mass spectrometry. Progression-associated proteins belong to the functional complexes of tumorigenesis, proliferation, differentiation, metabolism, and the regulation of major histocompatibility complex processing and other functions. Partial but significant overlap was revealed with previous proteomics and transcriptomics studies in CRC. Among various differentiation stage of CRC tissues, we identified calreticulin precursor, MHC class I antigen (human leukocyte antigen A ), glutathione S-transferase pi1, keratin 8, heat shock protein 27, tubulin beta chain, triosephosphate, fatty acid-binding protein, hemoglobin (deoxy) mutant with val b 1 replaced by met (HBB), and zinc finger protein 312 (FEZF2).

[Q]: Hepatic steatosis and nonalcoholic steatohepatitis (NASH) have been increasingly implicated in the genesis of hepatic fibrosis and cirrhosis. However, no consensus exists about whether weight reduction may reverse this process.', 'To assess the effect of Roux-en-Y gastric bypass (RYGBP) on the histological evolution of NASH diagnosed in 64 patients by routine liver biopsy ("first" biopsy) performed during surgery, we performed a "second" biopsy after 23.5 +/- 8.4 months in 16 patients (14 female, 2 male).', 'From the first to the second biopsy, BMI decreased from 53.4 +/- 8.8 kg/m2 to 31.1 +/- 4.7 kg/m2, arterial hypertension decreased from 75% to 43.8%, and type 2 diabetes decreased from 43.8% to zero. On the first biopsy, nonalcoholic fatty liver disease (NAFLD) type 3 was observed in 12 patients (75%) and type 4 in 4 (25%). The second biopsy revealed complete regression of NAFLD in 15 patients (93.7%) and only 1 (6.3%) had NAFLD type 1 (mild steatosis without inflammation). Complete regression of necroinflammatory activity was observed in all patients. Among the 4 patients presenting fibrosis in the first biopsy, complete remission was observed in 1 and improvement in 1. Two continued to show the same degree of fibrosis without evidence of disease activity. No worsening of steatosis, necroinflammatory activity or fibrosis was observed in any of the patients, and none progressed to cirrhosis.
