| 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 |
| 2 | 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 |
| 3 | High-contrast,fast chemical imaging by coherent Raman scattering using a self-synchronized two-colour fibre laser显示文摘Coherent Raman scattering(CRS)microscopy is widely recognized as a powerful tool for tackling biomedical problems based on its chemically specific label-free contrast,high spatial and spectral resolution,and high sensitivity.However,the clinical translation of CRS imaging technologies has long been hindered by traditional solid-state lasers with environmentally sensitive operations and large footprints.Ultrafast fibre lasers can potentially overcome these shortcomings but have not yet been fully exploited for CRS imaging,as previous implementations have suffered from high intensity noise,a narrow tuning range and low power,resulting in low image qualities and slow imaging speeds.Here,we present a novel high-power self-synchronized two-colour pulsed fibre laser that achieves excellent performance in terms of intensity stability(improved by 50 dB),timing jitter(24.3 fs),average power fluctuation(<0.5%),modulation depth(>20 dB)and pulse width variation(<1.8%)over an extended wavenumber range(2700-3550 cm^(−1)).The versatility of the laser source enables,for the first time,high-contrast,fast CRS imaging without complicated noise reduction via balanced detection schemes.These capabilities are demonstrated in this work by imaging a wide range of species such as living human cells and mouse arterial tissues and performing multimodal nonlinear imaging of mouse tail,kidney and brain tissue sections by utilizing second-harmonic generation and twophoton excited fluorescence,which provides multiple optical contrast mechanisms simultaneously and maximizes the gathered information content for biological visualization and medical diagnosis.This work also establishes a general scenario for remodelling existing lasers into synchronized two-colour lasers and thus promotes a wider popularization and application of CRS imaging technologies. | Cihang Kong Christian Pilger Henning Hachmeister Xiaoming Wei Tom H.Cheung Cora S.W.Lai Nikki P.Lee Kevin K.Tsia Kenneth K.Y.Wong Thomas Huser | 2020 | Light(Science & Applications)2020，9，1： | 5 |
| 4 | 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 |

| 7 | Three-dimensional imaging of the uterus:The value of the coronal plane显示文摘Advent in three-dimensional(3D) imaging technology has seen 3D ultrasound establish itself as a useful adjunct complementary to traditional two-dimensional imaging of the female pelvis. This advantage largely arises from its ability to reconstruct the coronal plane of the uterus, which allows further delineation of many gynecological disorders. 3D imaging of the uterus is now the preferred imaging modality for assessing congenital uterine anomalies and intrauterine device localization. Newer indications include the diagnosis of adenomyosis. It can also add invaluable information to delineate other endometrial and myometrial pathology such as fibroids and endometrial polyps. | Lufee Wong Nikki White Jayshree Ramkrishna Edward Araujo Júnior Simon Meagher Fabricio Da Silva Costa | 2015 | World Journal of Radiology2015，7，12： | 3 |
| 8 | 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 |
| 9 | Brief electrical nerve stimulation enhances intrinsic repair capacity of the focally demyelinated central nervous system显示文摘Our lab has shown that brief electrical nerve stimulation(ES)has a dramatic impact on remyelination of lysophosphatidyl choline(LPC)-induced focally demyelinated rat peripheral nerves,while also inducing an axon-protective phenotype and shifting macrophages from a predominantly pro-inflammatory toward a pro-repair phenotype.Whether this same potential exists in the central nervous system is not known.Thus,for proof of principle studies,the peripheral nerve demyelination and ES model was adapted to the central nervous system,whereby a unilateral focal LPC-induced demyelination of the dorsal column at the lumbar enlargement where the sciatic nerve afferents enter was created,so that subsequent ipsilateral sciatic nerve ES results in increased neural activity in the demyelinated axons.Data reveal a robust focal demyelination at 7 days post-LPC injection.Delivery of 1-hour ES at 7 days post-LPC polarizes macrophages/microglia toward a pro-repair phenotype when examined at 14 days post-LPC;results in smaller LPC-associated regions of inflammation compared to non-stimulated controls;results in significantly more cells of the oligodendroglial lineage in the demyelinated region;elevates myelin basic protein levels;and shifts the paranodal protein Caspr along demyelinated axons to a more restricted distribution,consistent with reformation of the paranodes of the nodes of Ranvier.ES also significantly enhanced levels of phosphorylated neurofilaments detected in the zones of demyelination,which has been shown to confer axon protection.Collectively these findings support that strategies that increase neural activity,such as brief electrical stimulation,can be beneficial for promoting intrinsic repair following focal demyelinating insults in demyelinating diseases such as multiple sclerosis.All animal procedures performed were approved by the University of Saskatchewan's Animal Research Ethics Board(protocol#20090087;last approval date:November 5,2020). | Lydia Ayanwuyi Nataliya Tokarska Nikki A.McLean Jayne M.Johnston Valerie M.K.Verge | 2022 | Neural Regeneration Research2022，17，5： | 3 |
| 10 | Cytokine gene polymorphisms and graft-versus-host disease in children after matched sibling hematopoietic stem cell transplantation:a single-center experience显示文摘Various polymorphisms in cytokine genes have recently been investigated as candidate risk factors in allogeneic hematopoetic stem cell transplantation(allo-HSCT).We retrospectively analyzed specific polymorphisms in genes for interleukin(IL)-10,IL-6,tumor-necrosis factor alpha(TNF-α)and interferon gamma(IFN-c)in a pediatric cohort of 57 histocompatibility leucocyte antigen(HLA)-identical sibling myeloablative transplants.Both recipient and donor genotypes were tested for association with graft-versus-host disease(GVHD)by statistical methods including Cox regression analysis.We found a significant association between the IL-10 promoter haplotype polymorphisms at positions-1082,-819 and-592 with the occurrence of severe(grades Ⅲ–Ⅳ)acute GVHD(aGVHD).Recipients with the haplotype GCC had a statistically significant decreased risk of severe aGVHD(hazard risk(HR)50.20,95% confidence interval(CI):0.06–0.67)in comparison with patients with other IL-10 haplotypes(P50.008).Transplant-related mortality at 1 year was significantly lower in recipients with this haplotype(HR50.17,95% CI:0.012–0.320)versus other IL-10 haplotypes(P=0.03),whereas overall survival was not influenced by IL-10 haplotype polymorphisms.In multivariate analysis,the presence of the IL-10 GCC haplotype was found as the only variable associated with a statistically significant decreased hazard of severe aGVHD development(P=0.02,HR50.21,95% CI:0.05–0.78).These results suggest that pediatric patients possessing the IL-10 GCC haplotype may be protected from the occurrence of severe aGVHD in the setting of matched sibling HSCT. | Evgenios Goussetis Ioanna Varela Ioulia Peristeri Vasiliki Kitra Kleopatra Spanou Olga Moraloglou Anna Paisiou Sofia Karatasaki Alexandra Soldatou Nikki Constantinidou Stelios Graphakos | 2011 | Cellular & Molecular Immunology2011，8，3： | 2 |
