| 1 | Daily genetic profiling indicates JAK/STAT signaling promotes early hepatic stellate cell transdifferentiation显示文摘AIM: To identify signaling pathways and genes that initiate and commit hepatic stellate cells (HSCs) to transdifferentiation. METHODS: Primary HSCs were isolated from male Sprague-Dawley rats and cultured on plastic for 0-10 d. Gene expression was assessed daily (quiescent to day 10 culture-activation) by real time polymerase chain reaction and data clustered using AMADA software. The significance of JAK/STAT signaling to HSC transdifferentiation was determined by treating cells with a JAK2 inhibitor. RESULTS: Genetic cluster analyses, based on expression of these 21 genes, showed similar expression profiles on days 1-3, days 5 and 6, and days 7-10, while freshly isolated cells (day Q) and day 4 cells were genotypically distinct from any of the other days. Additionally, gene expression clustering revealed strong upregulation of interleukin-6, JAK2 and STAT3 mRNA in the early stages of activation. Inhibition of the JAK/STAT signaling pathway impeded the morphological transdifferentiation of HSCs which correlated with decreased mRNA expression of several profibrotic genes including collagens, α-SMA, PDGFR and TGFβR. CONCLUSION: These data demonstrate unique clustered genetic profiles during the daily progression of HSC transdifferentiation and that JAK/STAT signaling may be critical in the early stages of transdifferentiation. | Ashley M Lakner Cathy C Moore Alyssa A Gulledge Laura W Schrum | 2010 | World Journal of Gastroenterology2010，16，40： | 23 |
| 2 | microRNAs: Fad or future of liver disease显示文摘microRNAs (miRs) are small non-coding RNAs that regulate both mRNA and protein expression of target genes, which results in alterations in mRNA stability or translation inhibition. miRs influence at least one third of all human transcripts and are known regulators of various important cellular growth and differentiation factors. miRs have recently emerged as key regulatory molecules in chronic liver disease. This review details recent contributions to the field of miRs that influence liver development and the broad spectrum of disease, from non-alcoholic fatty liver disease to fibrosis/cirrhosis, with particular emphasis on hepatic stellate cells and potential use of miRs as therapeutic tools. | Ashley M Lakner Herbert L Bonkovsky Laura W Schrum | 2011 | World Journal of Gastroenterology2011，17，20： | 13 |
| 3 | Targeting collagen expression in alcoholic liver disease显示文摘Alcoholic liver disease(ALD)is a leading cause of liver disease and liver-related deaths globally,particularly in developed nations.Liver fibrosis is a consequence of ALD and other chronic liver insults,which can progress to cirrhosis and hepatocellular carcinoma if left un-treated.Liver fibrosis is characterized by accumulation of excess extracellular matrix components,including typeⅠcollagen,which disrupts liver microcirculation and leads to injury.To date,there is no therapy for the treatment of liver fibrosis;thus treatments that either prevent the accumulation of typeⅠcollagen or hasten its degradation are desirable.The focus of this review is to examine the regulation of typeⅠcollagen in fibrogenic cells of the liver and to discuss current advances in therapeutics to eliminate excessive collagen deposition. | Kyle J Thompson Iain H McKillop Laura W Schrum | 2011 | World Journal of Gastroenterology2011，17，20： | 7 |
| 4 | FK506对实验性卒中疗效的系统评价和Meta分析显示文摘FK506是治疗急性卒中的一种候选用药。决定一种药物是否可以用于临床试验,应当以全面的、无偏倚的动物实验数据的评估为依据,同时还应考虑到这些数据的局限性。这种评估不但应包括药物疗效,而且也应包括药效在体内的特征和局限性。本研究应用系统评价和Meta分析的方法对FK506在卒中动物模型中保护作用的证据进行评价。总共纳入了29个描述了实验步骤的研究,包括1759只动物。结果显示,FK506疗效的点估计值(结局指标的改善)是31.3%[95%CI(0.272-0.354)]。在采用氯胺酮麻醉和短暂性脑缺血的动物实验中,FK506的疗效更高,在使用大鼠,合并其他疾病的动物及仅以梗死面积为疗效指标的实验中,FK506疗效较低。已发表的实验研究质量均接近临床试验标准,但在高质量的研究中,FK506的疗效较低。FK506在实验性脑卒中的研究中,虽然显示出有明显的疗效,但是应注意由于研究质量和可能的发表偏倚等冈素的影响,FK506的疗效可能被过高估计。 | Malcolm R Macleod Tori O’Collins Laura L Horky David W Howells Geoffrey A Donnan 段建钢 | 2006 | 中国循证医学杂志2006，6，6： | 3 |

| 6 | Legalon-SIL downregulates HCV core and NS5A in human hepatocytes expressing full-length HCV显示文摘AIM: To determine the effect of Legalon-SIL (LS) on hepatitis C virus (HCV) core and NS5A expression and on heme oxygenase-1 (HMOX-1) and its transcriptional regulators in human hepatoma cells expressing full length HCV genotype 1b. METHODS: CON1 cells were treated with 50 μmol/L or 200 μmol/L LS. Cells were harvested after 2, 6 and 24 h. HCV RNA and protein levels were determined by quantitative real-time polymerase chain reaction and Western blotting, respectively. RESULTS: HCV RNA (core and NS5A regions) wasdecreased after 6 h with LS 200 μmol/L (P < 0.05). Both 50 and 200 μmol/L LS decreased HCV RNA levels [core region (by 55% and 88%, respectively) and NS5A region (by 62% and 87%, respectively) after 24 h compared with vehicle (dimethyl sulphoxide) control (P < 0.01). Similarly HCV core and NS5A protein were decreased (by 85%, P < 0.01 and by 65%, P < 0.05, respectively) by LS 200 μmol/L. Bach1 and HMOX-1 RNA were also downregulated by LS treatment (P < 0.01), while Nrf2 protein was increased (P < 0.05).CONCLUSION: Our results demonstrate that treatment with LS downregulates HCV core and NS5A expression in CON1 cells which express full length HCV genotype 1b, and suggests that LS may prove to be a valuable alternative or adjunctive therapy for the treatment of HCV infection. | Marjan Mehrab-Mohseni Hossein Sendi Nury Steuerwald Sriparna Ghosh Laura W Schrum Herbert L Bonkovsky | 2011 | World Journal of Gastroenterology2011，17，13： | 3 |
| 7 | Inflammation-related gene expression profiles of salivary extracellular vesicles in patients with head trauma显示文摘At present,there is no reliable biomarker for the diagnosis of traumatic brain injury(TBI).Studies have shown that extracellular vesicles released by damaged cells into biological fluids can be used as potential biomarkers for diagnosis of TBI and evaluation of TBI severity.We hypothesize that the genetic profile of salivary extracellular vesicles in patients with head trauma differs from that in uninjured subjects.Findings from this hypothesis would help investigate the severity of TBI.This study included 19 subjects,consisting of seven healthy controls who denied history of head trauma,six patients diagnosed with concussion injury from an outpatient concussion clinic,and six patients with TBI who received treatment in the emergency department within 24 hours after injury.Real-time PCR analysis of salivary extracellular vesicles in participants was performed using TaqMan Human Inflammation array.Gene expression analysis revealed nine upregulated genes in emergency department patients(LOX5,ANXA3,CASP1,IL2RG,ITGAM,ITGB2,LTA4H,MAPK14,and TNFRSF1A)and 13 upregulated genes in concussion clinic patients compared with healthy participants(ADRB1,ADRB2,BDKRB1,HRH1,HRH2,LTB4R2,LTB4R,PTAFR,CYSLTR1,CES1,KLK1,MC2R,and PTGER3).Each patient group had a unique profile.Comparison between groups showed that 15 inflammation-related genes had significant expression change.Our results indicate that inflammation biomarkers can be used for diagnosis of TBI and evaluation of disease severity.This study was approved by the Institutional Review Board on December 18,2015(approval No.0078-12)and on June 9,2016(approval No.4093-16). | Yan Cheng Mandy Pereira Neha P.Raukar John L.Reagan Mathew Quesenberry Laura Goldberg Theodor Borgovan W Curt LaFrance Jr Mark Dooner Maria Deregibus Giovanni Camussi Bharat Ramratnam Peter Quesenberry | 2020 | Neural Regeneration Research2020，15，4： | 2 |
