1Prognostic significance of tumor immune microenvironment and immunotherapy:Novel insights and future perspectives in gastric cancer显示文摘Despite a decrease in gastric cancer incidence, the development of novel biologic agents and combined therapeutic strategies, the prognosis of gastric cancer remains poor. Recently, the introduction of modern immunotherapy, especially using immune checkpoint inhibitors, led to an improved prognosis in many cancers. The use of immunotherapy was also associated with manageable adverse event profiles and promising results in the treatment of patients with gastric cancer, especially in heavily pretreated patients. These data have led to an accelerated approval of some checkpoint inhibitors in this setting. Understanding the complex relationship between the host immune microenvironment and tumor and the immune escape phenomenon leading to cancer occurrence and progression will subsequently lead to the identification of prognostic immune markers. Furthermore, this understanding will result in the discovery of both new mechanisms for blocking tumor immunosuppressive signals and pathways to stimulate the local immune response by targeting and modulating different subsets of immune cells. Due to the molecular heterogeneity of gastric cancers associated with differentclinico-biologic parameters, immune markers expression and prognosis, novel immunotherapy algorithms should be personalized and addressed to selected subsets of gastric tumors, which have been proven to elicit the best clinical responses. Future perspectives in the treatment of gastric cancer include tailored dual immunotherapies or a combination of immunotherapy with other targeted agents with synergistic antitumor effects.Daniela Cornelia Lazǎr Mihaela Flavia Avram Ioan Romosan Mǎrioara Cornianu Sorina Tǎan Adrian Goldis 2018World Journal of Gastroenterology2018,24,32:24
2Comparison of the liver stiffness measurement by transient elastography with the liver biopsy显示文摘AIM: To compare the liver stiffness (LS) measurement by transient elastography (TE) to the liver biopsy (LB)-considered the 'gold standard' in the evaluation of patients with chronic hepatitis C. METHODS: During a period of 12 mo, we evaluated 199 consecutive patients with chronic hepatitis due to hepatitis C virus (HCV), in which LB and LS assessments (by means of TE) were performed during the same session. RESULTS: Out of 199 patients, a valid measurement of the LS could not be obtained in 8. The mean value of LS in the cohort of 191 valid measurements was 8.45 ± 4.96 kPa, ranging from 2.3 to 38 kPa. The mean value of LS in patients with signifi cant fi brosis at biopsy (161 patients with F ≥ 2 according to Metavir) was 9.02 ± 5.15 kPa, significantly higher than in patients with no or mild fi brosis (30 patients with F < 2 Metavir): 5.39 ± 1.81 kPa (P < 0.0001). For a cut- off value of 6.8 kPa, the LS had a PPV of 98%, a NPV of 30.1%, a sensitivity of 59.6% and a specificity of 93.3% for the presence of signifi cant fi brosis (at least F2 Metavir), with a diagnostic performance of 77.3% (AUROC 0.773). Using this cut-off value, we reached the best discrimination between absence of fibrosis/ mild fibrosis (F < 2 Metavir) and the presence ofmoderate to severe fi brosis (F ≥ 2 Metavir). CONCLUSION: In patients with chronic hepatitis due to HCV, a cut-off value of 6.8 kPa measured by TE can differentiate between significant fibrosis and absent or mild fi brosis, with a PPV of 98%, a NPV of 30.1%, a sensitivity of 59.6%, a specificity of 93.3%, and a diagnostic performance of 77.3%.Ioan Sporea Roxana ■irli Alexandra Deleanu Adriana Tudora Manuela Curescu Marioara Cornianu Daniela Lazǎr 2008World Journal of Gastroenterology2008,14,42:20

4The transcription factor ZEB1 promotes chemoresistance in prostate cancer cell lines显示文摘One of the factors promoting tumoral progress is the abnormal activation of the epithelial-mesenchymal transition(EMT)program which has been associated with chemoresistance in tumoral cells.The transcription factor zinc finger E-box-binding homeobox 1(ZEB1),a key EMT activator,has recently been related to docetaxel resistance,the main chemotherapeutic used in advanced prostate cancer treatment.The mechanisms involved in this protective effect are still unclear.In a previous work,we demonstrated that ZEB1 expression induced an EMT-like phenotype in prostate cancer cell lines.In this work,we used prostate cancer cell lines 22Rvl and DU145 to study the effect of ZEB1 modulation on docetaxel resistance and its possible mechanisms.The results showed that ZEB1 overexpression conferred to 22Rvl cell resistance to docetaxel while its silencing made DU145 cells more sensitive to it.Analysis of resistance markers showed no presenee of ATP-binding cassette subfamily B member 1(MDR1)and no changes in breast cancer resistance protein(BCRP)or ATP-binding cassette subfamily C member 10(MRP7).However,a correlation between ZEB1,multidrug resistance-associated protein 1(MRP1),and ATP-binding cassette subfamily C member 4(MRP4)expression was observed.MRP4 inhibition,using MK571,resensitized cells with ZEB1 overexpression to docetaxel treatment.In addition,modulation of ZEB1 and subsequent change in MRP4 expression correlated with a lower apoptotic response to docetaxel,characterized by lower B-cell lymphoma 2(Bcl2),high BCL2-associated X protein(Bax),and high active caspase 3 expression.The response to docetaxel in our model seems to be mediated mainly by activation of the apoptotic death program.Our results showed that modulation of MRP4 could be a mediator of ZEBl-related resistance to docetaxel in prostate cancer,making it a possible marker for chemotherapy response in patients who do not express MDR1.Octavio Orellana-Serradell Daniela Herrera Enrique A Castellon Hector R Contreras 2019Asian Journal of Andrology2019,21,5:5

6The complete reference genome for grapevine (Vitis vinifera L.) genetics and breeding显示文摘Grapevine is one of the most economically important crops worldwide.However,the previous versions of the grapevine reference genome tipically consist of thousands of fragments with missing centromeres and telomeres,limiting the accessibility of the repetitive sequences,the centromeric and telomeric regions,and the study of inheritance of important agronomic traits in these regions.Here,we assembled a telomere-to-telomere(T2T)gap-free reference genome for the cultivar PN40024 using PacBio HiFi long reads.The T2T reference genome(PN_T2T)is 69 Mb longer with 9018 more genes identified than the 12X.v0 version.We annotated 67%repetitive sequences,19 centromeres and 36 telomeres,and incorporated gene annotations of previous versions into the PN_T2T assembly.We detected a total of 377 gene clusters,which showed associations with complex traits,such as aroma and disease resistance.Even though PN40024 derives from nine generations of selfing,we still found nine genomic hotspots of heterozygous sites associated with biological processes,such as the oxidation–reduction process and protein phosphorylation.The fully annotated complete reference genome therefore constitutes an important resource for grapevine genetic studies and breeding programs.Xiaoya Shi Shuo Cao Xu Wang Siyang Huang Yue Wang Zhongjie Liu Wenwen Liu Xiangpeng Leng Yanling Peng Nan Wang Yiwen Wang Zhiyao Ma Xiaodong Xu Fan Zhang Hui Xue Haixia Zhong Yi Wang Kekun Zhang Amandine Velt Komlan Avia Daniela Holtgräwe Jérôme Grimplet JoséTomás Matus Doreen Ware Xinyu Wu Haibo Wang Chonghuai Liu Yuling Fang Camille Rustenholz Zongming Cheng Hua Xiao Yongfeng Zhou 2023Horticulture Research2023,10,5:3

8Chronic hepatitis C virus infection:Serum biomarkers inpredicting liver damage显示文摘Currently, a major clinical challenge in the management of the increasing number of hepatitis C virus(HCV) infected patients is determining the best means for evaluating liver impairment. Prognosis and treatment of chronic hepatitis C(CHC) are partly dependent on the assessment of histological activity, namely cell necrosis and inflammation, and the degree of liver fibrosis. These parameters can be provided by liver biopsy; however, in addition to the risks related to an invasive procedure, liver biopsy has been associated with sampling error mostly due to suboptimal biopsy size. To avoid these pitfalls, several markers have been proposed as non-invasive alternatives for the diagnosis of liver damage. Distinct approaches among the currently available non-invasive methods are(1) the physical ones based on imaging techniques; and(2) the biological ones based on serum biomarkers. In this review, we discuss these approaches with special focus on currently available non-invasive serum markers. We will discuss:(1) class?Ⅰ?serum biomarkers individually and as combined panels, particularly those that mirror the metabolism of liver extracellular matrix turnover and/or fibrogenic cell changes;(2) class Ⅱ biomarkers that are indirect serum markers and are based on the evaluation of common functional alterations in the liver; and(3) biomarkers of liver cell death, since hepatocyte apoptosis plays a significant role in the pathogenesis of HCV infection. We highlight in this review the evidence behind the use of these markers and assess the diagnostic accuracy as well as advantages, limitations, and application in clinical practice of each test for predicting liver damage in CHC.Pamela Valva Daniela A Ríos Elena De Matteo Maria V Preciado 2016World Journal of Gastroenterology2016,22,4:2
