| 1 | Osteopontin as potential biomarker and therapeutic target in gastric and liver cancers显示文摘Gastric cancer and liver cancer are among the most common malignancies and the leading causes of death worldwide,due to late detection and high recurrence rates.Today,these cancers have a heavy socioeconomic burden,for which a full understanding of their pathophysiological features is warranted to search for promising biomarkers and therapeutic targets.Osteopontin (OPN) is overexpressed in most patients with gastric and liver cancers.Over the past decade,emerging evidence has revealed a correlation of OPN level and clinicopathological features and prognosis in gastric and liver cancers,indicating its potential as an independent prognostic indicator in such patients.Functional studies have verified the potential of OPN knockdown as a therapeutic approach in vitro and in vivo .Furthermore,OPN mediates multifaceted roles in the interaction between cancer cells and the tumor microenvironment,in which many details need further exploration.OPN signaling results in various functions,including prevention of apoptosis,modulation of angiogenesis,malfunction of tumor-associated macrophages,degradation of extracellular matrix,activation of phosphoinositide 3-kinase-Akt and nuclear factor-κB pathways,which lead to tumor formation and progression,particularly in gastric and liver cancers.This editorial aims to review recent findings on alteration in OPN expression and its clinicopathological associations with tumor progression,its potential as a therapeutic target,and putative mechanisms in gastric and liver cancers.Better understanding of the implications of OPN in tumorigenesis might facilitate development of therapeutic regimens to benefit patients with these deadly malignancies. | Dong-Xing Cao Zhi-Jie Li Xiao-Ou Jiang Yick Liang Lum Ester Khin Nikki P Lee Guo-Hao Wu John M Luk | 2012 | World Journal of Gastroenterology2012，18，30： | 29 |

| 3 | Role of LPS/CD14/TLR4-mediated inflammation in necrotizing enterocolitis:Pathogenesis and therapeutic implications显示文摘AIM:To establish the roles of lipopolysaccharide (LPS)/CD14/toll-like receptor 4 (TLR4)-mediated inflammation in a rat model of human necrotizing enterocolitis (NEC).METHODS: Six pairs of intestinal samples from human NEC were collected before and after recovery for histological and molecular analysis of inflammatory cytokines and signaling components. In the rat NEC model, we isolated 10-cm jejunum segments and divided them into six groups (n=6) for sham operation, treatment with LPS, bowel distension, combined bowel distension and LPS stimulation, and two therapeutic groups. The potential eff icacy of a recombinant CD18 peptide and a monoclonal CD14 antibody was evaluated in the latter two groups. The serum and tissue levels of several inflammatory mediators were quantified by real-time polymerase chain reaction, ELISA and immunoblotting.RESULTS: Human acute phase NEC tissues displayed significant increases (P<0.05) in levels of TLR4, CD14, myeloid differentiation protein (MD)-2, tumor necrosis factor (TNF)-α and nuclear factor-κB when compared to those after recovery. The histological and inflammatory picture of human NEC was reproduced in rats that were treated with combined bowel distension and LPS, but not in the sham-operated and other control rats. Serum levels of interleukin-6 and TNF-α were also elevated. The NEC pathology was attenuated by treating the NEC rats with a monoclonal CD14 antibody or an LPS-neutralizing peptide.CONCLUSION:LPS and distension are required to produce the histological and inflammatory features of NEC. A potential treatment option is blocking LPS activation and leukocyte infi ltration. | Kwong L Chan Kwong F Wong John M Luk | 2009 | World Journal of Gastroenterology2009，15，38： | 17 |
| 4 | Dickkopfs and Wnt/β-catenin signalling in liver cancer显示文摘Liver cancer is the fifth and seventh most common cause of cancer in men and women,respectively.Wnt/β-catenin signalling has emerged as a critical player in both the development of normal liver as well as an oncogenic driver in hepatocellular carcinoma(HCC).Based on the current understanding,this article summarizes the possible mechanisms for the aberrant activation of this pathway with specific focus on HCC.Furthermore,we will discuss the role of dickkopfs(DKKs)in regulating Wnt/β-catenin signalling,which is poorly understood and understudied.DKKs are a family of secreted proteins that comprise at least four members,namely DKK1-DKK4,which act as inhibitors of Wnt/β-catenin signalling.Nevertheless,not all members antagonize Wnt/β-catenin signalling.Their functional significance in hepatocarcinogenesis remains to be further characterized for which these studies should provide new insights into the regulatory role of DKKs in Wnt/β-catenin signalling in hepatic carcinogenesis.Because of the important oncogenic roles,there are an increasing number of therapeutic molecules targetingβ-catenin and the Wnt/β-catenin pathway for potential therapy of HCC. | Sarwat Fatima Nikki P Lee John M Luk | 2011 | World Journal of Clinical Oncology2011，2，8： | 11 |
| 5 | Cryopreservation for delayed circulating tumor cell isolation is a valid strategy for prognostic association of circulating tumor cells in gastroesophageal cancer显示文摘AIM To demonstrate the feasibility of cryopreservation of peripheral blood mononuclear cells(PBMCs) for prognostic circulating tumor cell(CTC) detection in gastroesophageal cancer.METHODS Using 7.5 m L blood samples collected in EDTA tubes from patients with gastroesopheagal adenocarcinoma, CTCs were isolated by epithelial cell adhesion molecule based immunomagnetic capture using the Iso Flux platform. Paired specimens taken during the same blood draw(n = 15) were used to compare number of CTCs isolated from fresh and cryopreserved PBMCs. Blood samples were processed within 24 h to recover the PBMC fraction, with PBMCs used for fresh analysis immediately processed for CTC isolation. Cryopreservation of PBMCs lasted from 2 wk to 25.2 mo(median 14.6 mo). CTCs isolated from pre-treatment cryopreserved PBMCs(n = 43) were examined for associations with clinicopathological variables and survival outcomes.RESULTS While there was a significant trend to a decrease in CTC numbers associated with cryopreserved specimens(mean number of CTCs 34.4 vs 51.5, P = 0.04), this was predominately in samples with a total CTC count of > 50, with low CTC count samples less affected(P = 0.06). There was no significant association between the duration of cryopreservation and number of CTCs. In cryopreserved PBMCs from patient samples prior to treatment, a high CTC count(> 17) was associated with poorer overall survival(OS)(n = 43, HR = 4.4, 95%CI: 1.7-11.7, P = 0.0013). In multivariate analysis, after controlling for sex, age, stage, ECOG performance status, and primary tumor location, a high CTC count remained significantly associated with a poorer OS(HR = 3.7, 95%CI: 1.2-12.4, P = 0.03). CONCLUSION PBMC cryopreservation for delayed CTC isolation is a valid strategy to assist with sample collection, transporting and processing. | Daniel Brungs David Lynch Alison WS Luk Elahe Minaei Marie Ranson Morteza Aghmesheh Kara L Vine Martin Carolan Mouhannad Jaber Paul de Souza Therese M Becker | 2018 | World Journal of Gastroenterology2018，24，7： | 5 |
| 6 | Hepatic tight junctions:From viral entry to cancer metastasis显示文摘The tight junction (TJ) is a critical cellular component for maintenance of tissue integrity, cellular interactions and cell-cell communications, and physiologically functions as the 'great wall' against external agents and the surrounding hostile environment. During the host-pathogen evolution, viruses somehow found the key to unlock the gate for their entry into cells and to exploit and exhaust the host cells. In the liver, an array of TJ molecules is localized along the bile canaliculi forming the blood-biliary barrier, where they play pivotal roles in paracellular permeability, bile secretion, and cell polarity. In pathology, certain hepatic TJ molecules mediate virus entry causing hepatitis infection; deregulation and functional abnormality of the TJ have also been implicated in triggering liver cancer development and metastasis. All these findings shed new insights on the understanding of hepatic TJs in the development of liver disease and provide new clues for potential intervention. | Nikki P Lee John M Luk | 2010 | World Journal of Gastroenterology2010，16，3： | 4 |

| 8 | Tensile and fracture properties of an Mg-RE-Zn alloy at elevated temperatures显示文摘Magnesium alloy EZ10(Mg-RE-Zn) was deformed in tension at temperatures from 20 up to 520 °C. A rapid decrease of the yield and tensile strength with temperature was observed at temperatures higher than 300 °C. On the other hand, ductility of samples rapidly increased in the same temperature range. Light microscopy and scanning electron microscopy was used to reveal the reason for these behaviours. Intermetallic particles in grain boundaries are responsible for excellent mechanical properties at lower temperatures. Diffusional processes occurring at temperatures higher than 300 °C significantly influenced the deformation mechanism as well as the fracture character. | TROJANOVZuzanka DONI Tibor LUK Pavel PALEK Peter CHALUPOV Mária TILLOV Eva BASTOVANSKY Ronald | 2014 | Journal of Rare Earths2014，32，6： | 3 |
| 9 | Tumor necrosis factor-α-induced protein 1 and immunity to hepatitis B virus显示文摘AIM: To compare the gene expression profile in a pair of HBV-infected twins.METHODS: The gene expression profile was compared in a pair of HBV-infected twins.RESULTS: The twins displayed different disease outcomes. One acquired natural immunity against HBV,whereas the other became a chronic HBV carrier. Eightyeight and forty-six genes were found to be up- or downregulated in their PBMCs, respectively. Tumor necrosis factor-alpha-induced protein 1 (TNF-αIP1) that expressed at a higher level in the HBV-immune twins was identified and four pairs of siblings with HBV immunity by RTPCR. However, upon HBV core antigen stimulation,TNF-αIP1 was downregulated in PBMCs from subjects with immunity, whereas it was slightly upregulated in HBV carriers. Bioinformatics analysis revealed a K+channel tetramerization domain in TNF-αIP1 that shares a significant homology with some human, mouse, and C elegan proteins.CONCLUSION: TNF-αIP1 may play a role in the innate immunity against HBV. | Marie C Lin Nikki P Lee Ning Zheng Pai-Hao Yang Oscar G Wong Hsiang-Fu Kung Chee-Kin Hui John M Luk George Ka-Kit Lau | 2005 | World Journal of Gastroenterology2005，11，48： | 3 |
