| 1 | Portal vein thrombosis in cirrhosis: Controversies and latest developments显示文摘Portal vein thrombosis(PVT) is encountered in livercirrhosis, particularly in advanced disease. It has been a feared complication of cirrhosis, attributed to significant worsening of liver disease, poorer clinical outcomes and potential inoperability at liver transplantation; also catastrophic events such as acute intestinal ischaemia. Optimal management of PVT has not yet been addressed in any consensus publication.We review current literature on PVT in cirrhosis; its prevalence, pathophysiology, diagnosis, impact on the natural history of cirrhosis and liver transplantation,and management. Studies were identified by a search strategy using MEDLINE and Google Scholar. The incidence of PVT increases with increasing severity of liver disease: less than 1% in well-compensated cirrhosis, 7.4%-16% in advanced cirrhosis. Prevalence in patients undergoing liver transplantation is 5%-16%.PVT frequently regresses instead of uniform thrombus progression. PVT is not associated with increased risk of mortality. Optimal management has not been addressed in any consensus publication. We propose areas for future research to address unresolved clinical questions. | Damian J Harding M Thamara PR Perera Frederick Chen Simon Olliff Dhiraj Tripathi | 2015 | World Journal of Gastroenterology2015，21，22： | 42 |
| 2 | MicroRNAs, development of Barrett’s esophagus, and progression to esophageal adenocarcinoma显示文摘Barrett's esophagus is a premalignant condition caused by gastroesophageal reflux. Once developed, it can progress through varying grades of dysplasia to esoph-ageal adenocarcinoma. Whilst it is well accepted that Barrett's esophagus is caused by gastroesophageal reflux, the molecular mechanisms of its pathogenesis and progression to cancer remain unclear. MicroRNAs (miRNAs) are short segments of RNA that have been shown to control the expression of many human genes. They have been implicated in most cellular processes, and the role of miRNAs in disease development is be-coming increasingly evident. Understanding altered miRNA expression is likely to help unravel the molecular mechanisms that underpin the development of Barrett's esophagus and its progression to cancer. | Cameron M Smith David I Watson Michael Z Michael Damian J Hussey | 2010 | World Journal of Gastroenterology2010，16，5： | 23 |
| 3 | miR-200 family expression is downregulated upon neoplastic progression of Barrett's esophagus显示文摘AIM: To investigate miR-200 family expression in Barrett's epithelium, gastric and duodenal epithelia, and esophageal adenocarcinoma. METHODS: Real-time reverse transcriptase-polymerase chain reaction was used to measure miR-200, ZEB1 and ZEB2 expression. Ingenuity Pathway Analysis of miR-200 targets was used to predict biological outcomes. RESULTS: Barrett's epithelium expressed lower levels of miR-141 and miR-200c than did gastric and duodenal epithelia (P < 0.001). In silico analysis indicated roles for the miR-200 family in molecular pathways that distinguish Barrett's epithelium from gastric and duodenalepithelia, and which control apoptosis and proliferation. All miR-200 members were downregulated in adenocarcinoma (P < 0.02), and miR-200c expression was also downregulated in non-invasive epithelium adjacent to adenocarcinoma (P < 0.02). The expression of all miR-200 members was lower in Barrett's epithelium derived high-grade dysplastic cell lines than in a cell line derived from benign Barrett's epithelium. We observed signif icant inverse correlations between miR-200 family expression and ZEB1 and ZEB2 expression in Barrett's epithelium and esophageal adenocarcinoma (P < 0.05). CONCLUSION: miR-200 expression might contribute to the anti-apoptotic and proliferative phenotype of Barrett's epithelium and regulate key neoplastic processes in this epithelium. | Cameron M Smith David I Watson Mary P Leong George C Mayne Michael Z Michael Bas PL Wijnhoven Damian J Hussey | 2011 | World Journal of Gastroenterology2011，17，8： | 13 |
| 4 | MicroRNA signatures in chemotherapy resistant esophageal cancer cell lines显示文摘AIM:To investigate expression of microRNA(miRNA)and potential targets in chemotherapy resistant esoph-ageal cancer cell lines.METHODS:An in-vitro model of acquired chemotherapy resistance in esophageal adeno-(EAC)and squamous cell carcinoma(ESCC)cells was used,and microRNA expression profiles for cisplatin or 5-fluorouracil(5-FU)resistant variants vs chemotherapy sensitive controls were compared using microarray and quantitative real-time polymerase chain reaction(PCR).The expression of chemotherapy-relevant genes potentially targeted by the dysregulated microRNAs in the chemotherapy resistant variants was also evaluated.RESULTS:Chemotherapy resistant sublines were found to have specific miRNA signatures,and these miRNA signatures were different for the cisplatin vs 5-FU resistant cells from the same tumor cell line,and also for EAC vs ESCC cells with resistance to the same specific chemotherapy agent.Amongst others,miR-27b-3p,miR-193b-3p,miR-192-5p,miR-378 a-3p,miR-125a-5p and miR-18a-3p were dysregulated,consistent with negative posttranscriptional control of KRAS,TYMS,ABCC3,CBL-B and ERBB2 expression via these miRNAs.CONCLUSION:The current study supports the hypothesis that microRNA expression has an impact on chemotherapy resistance in esophageal cancer. | Richard Hummel Corina Sie David I Watson Tingting Wang Alfiya Ansar Michael Z Michael Mark Van der Hoek Joerg Haier Damian J Hussey | 2014 | World Journal of Gastroenterology2014，20，40： | 8 |
| 5 | Estrogen,male dominance and esophageal adenocarcinoma:Is there a link?显示文摘Esophageal adenocarcinoma is a cancer with poor prognosis,and its incidence has risen sharply over recent decades.Obesity is a major risk factor for developing this cancer and there is a clear male gender bias in the incidence that cannot be fully explained by known risk factors.It is possible that a difference in the expression of estrogen,or its signaling axes,may contribute to this gender bias.We undertook a comprehensive literature search and analyzed the available data regarding estrogen and estrogen receptor expression,and the possible sex-specific links with esophageal adenocarcinoma development.Potentially relevant associations between visceral vs subcutaneous fat deposition and estrogen expression,and the effect of crosstalk between estrogen and leptin signaling were identified.We also found limited studies suggesting a role for estrogen receptor β expression in esophageal adenocarcinoma development.The current literature supports speculation on an etiological role for estrogen in the male gender bias in esophageal adenocarcinoma,but further studies are required. | Huiqi Yang Olga A Sukocheva Damian J Hussey David I Watson | 2012 | World Journal of Gastroenterology2012，18，5： | 7 |
| 6 | G protein-coupled estrogen receptor in colon function, immune regulation and carcinogenesis显示文摘Estrogens play important roles in the development and progression of multiple tumor types.Accumulating evidence points to the significance of estrogen action not only in tumors of hormonally regulated tissues such as the breast,endometrium and ovary,but also in the development of colorectal cancer(CRC).The effects of estrogens in physiological and pathophysiological conditions are mediated by the nuclear estrogen receptorsαandβ,as well as the membranebound G protein-coupled estrogen receptor(GPER).The roles of GPER in CRC development and progression,however,remain poorly understood.Studies on the functions of GPER in the colon have shown that this estrogen receptor regulates colonic motility as well as immune responses in CRC-associated diseases,such as Crohn’s disease and ulcerative colitis.GPER is also involved in cell cycle regulation,endoplasmic reticulum stress,proliferation,apoptosis,vascularization,cell migration,and the regulation of fatty acid and estrogen metabolism in CRC cells.Thus,multiple lines of evidence suggest that GPER may play an important role in colorectal carcinogenesis.In this review,we present the current state of knowledge regarding the contribution of GPER to colon function and CRC. | Damian Jacenik Ellen J Beswick Wanda M Krajewska Eric R Prossnitz | 2019 | World Journal of Gastroenterology2019，25，30： | 6 |
| 7 | MicroRNA profile in neosquamous esophageal mucosa following ablation of Barrett's esophagus显示文摘AIM To investigate the micro RNA expression profile in esophageal neosquamous epithelium from patients who had undergone ablation of Barrett's esophagus.METHODS High throughput screening using Taq Man~ Array Human Micro RNA quantitative PCR was used to determine expression levels of 754 micro RNAs in distal esophageal mucosa(1 cm above the gastro-esophageal junction) from 16 patients who had undergone ablation of non-dysplastic Barrett's esophagus using argon plasma coagulation vs pretreatment mucosa, posttreatment proximal normal non-treated esophageal mucosa, and esophageal mucosal biopsies from 10 controls without Barrett's esophagus. Biopsies of squamous mucosa were also taken from 5 cm above the pre-ablation squamo-columnar junction. Predicted m RNA target pathway analysis was used to investigate the functional involvement of differentially expressed micro RNAs.RESULTS Forty-four micro RNAs were differentially expressed between control squamous mucosa vs post-ablation neosquamous mucosa. Nineteen micro RNAs were differentially expressed between post-ablation neosquamous and post-ablation squamous mucosa obtained from the more proximal non-treated esophageal segment. Twelve microRNAs were differentially expressed in both neosquamous vs matched proximal squamous mucosa and neosquamous vs squamous mucosa from healthy patients. Nine micro RNAs(mi R-424-5p, mi R-127-3p, mi R-98-5p, mi R-187-3p, mi R-495-3p, mi R-34c-5p, mi R-223-5p, mi R-539-5p, mi R-376a-3p, mi R-409-3p) were expressed at higher levels in post-ablation neosquamous mucosa than in matched proximal squamous and healthy squamous mucosa. These micro RNAs were also more highly expressed in Barrett's esophagus mucosa than matched proximal squamous and squamous mucosa from controls. Target prediction and pathway analysis suggests that these micro RNAs may be involved in the regulation of cell survival signalling pathways. Three micro RNAs(mi R-187-3p, mi R-135b-5p and mi R-31-5p) were expressed at higher levels in postablation neosquamous mucosa than in matched proximal squamous and healthy squamous mucosa. These mi RNAs were expressed at similar levels in preablation Barrett's esophagus mucosa, matched proximal squamous and squamous mucosa from controls. Target prediction and pathway analysis suggests that these micro RNAs may be involved in regulating the expression of proteins that contribute to barrier function.CONCLUSION Neosquamous mucosa arising after ablation of Barrett's esophagus expresses micro RNAs that may contribute to decreased barrier function and micro RNAs that may be involved in the regulation of survival signaling pathways. | Loveena Sreedharan George C Mayne David I Watson Timothy Bright Reginald V Lord Alfiya Ansar Tingting Wang Jakob Kist David StJ Astill Damian J Hussey | 2017 | World Journal of Gastroenterology2017，23，30： | 3 |
| 8 | Androgens and esophageal cancer: What do we know?显示文摘Significant disparities exist between genders for the development and progression of several gastrointestinal(GI) diseases including cancer. Differences in incidence between men vs women for colon, gastric and hepatocellular cancers suggest a role for steroid sex hormones in regulation of GI carcinogenesis. Involvement of intrinsic gender-linked mechanisms is also possible for esophageal adenocarcinoma as its incidence is disproportionally high among men. However, the cause of the observed gender differences and the potential role of androgens in esophageal carcinogenesis remains unclear, even though the cancer-promoting role of androgen receptors(AR) shown in other cancers such as prostate and bladder suggests this aspect warrants exploration. Several studies have demonstrated expression of ARs in esophageal cancer. However, only one study has suggested a potential link between AR signaling and outcome- poorer prognosis. Two groups have analyzed data from cohorts with prostate cancer and one of these found a decreased incidence of esophageal squamous and adenocarcinoma after androgen deprivation therapy. However, very limited information is available about the effects of androgen and AR-initiated signaling on esophageal cancer cell growth in vitro and in vivo. Possible mechanisms for androgens/AR involvement in the regulation of esophageal cancer growth are considered, and the potential use of AR as a prognostic factor and clinical target is highlighted, although insufficient evidence is available to support clinical trials of novel therapies. As esophageal adenocarcinoma is a gender linked cancer with a large male predominance further studies are warranted to clarify the role of androgens and ARs in shaping intracellular signaling and genomic responses in esophageal cancer. | Olga A Sukocheva Bin Li Steven L Due Damian J Hussey David I Watson | 2015 | World Journal of Gastroenterology2015，21，20： | 2 |
