| 2 | Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets. | Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo | 2021 | World Journal of Clinical Oncology2021，12，10： | 5 |

| 5 | road to stemness in hepatocellular carcinoma显示文摘Carcinogenic process has been proposed to relay on the capacity to induce local tissue damage and proliferative repair. Liver has a great regeneration capacity and currently, most studies point towards the dominant role of hepatocytes in regeneration at all levels of liver damage. The most frequent liver cancer is hepatocellular carcinoma(HCC). Historical findings originally led to the idea that the cell of origin of HCC might be a progenitor cell. However, current linage tracing studies put the progenitor hypothesis of HCC origin into question. In agreement with their dominant role in liver regeneration, mature hepatocytes are emerging as the cell of origin of HCC, although, the specific hepatocyte subpopulation of origin is yet to be determined. The relationship between the cancer cell of origin(CCO) and cancer-propagating cells, known as hepatic cancer stem cell(HCSC) is unknown. It has been challenging to identify the definitive phenotypic marker of HCSC, probably due to the existence of different cancer stem cells(CSC) subpopulations with different functions within HCC. There is a dynamic interconversion among different CSCs, and between CSC and non-CSCs. Because of that, CSC-state is currently defined as a description of a highly adaptable and dynamic intrinsic property of tumor cells, instead of a static subpopulation of a tumor. Altered conditions could trigger the gain of stemness, some of them include: EMT-MET, epigenetics, microenvironment and selective stimulus such as chemotherapy. This CSC heterogeneity and dynamism makes them out reach from therapeutic protocols directed to a single target. A further avenue of research in this line will be to uncover mechanisms that trigger this interconversion of cell populations within tumors and target it. | Teresita NJ Flores-Téllez Saúl Villa-Trevino Carolina Pina-Vázquez | 2017 | World Journal of Gastroenterology2017，23，37： | 4 |
| 6 | Celecoxib enhances the detoxification of diethylnitrosamine in rat liver cancer显示文摘AIM:To study the effect of celecoxib(CXB) on diethylnitrosamine activation through the regulation of cytochrome P450 in a hepatocarcinogenesis model.METHODS:Six-week-old male Sprague-Dawley rats were randomly divided into fi ve groups,a non-treated group(NT) ,a diethylnitrosamine-treated group(DEN) ,a DEN+CXB-treated group(DEN+CXB) ,and CXB 8 d-treated and CXB 32 d-treated groups.The effects of celecoxib on the enzymatic activities of CYP1A1,2A,2B1/2,and 2E1 were assessed in hepatic microsomes 24 h after DEN administration.Changes in CYP1A1 and CYP2B1/2 protein expression were also evaluated.The rate of DEN metabolism was measured by the production of the deethylation metabolite acetaldehyde,and the denitrosation metabolite nitrite.RESULTS:DEN+CXB administration produced a significant increase in the enzymatic activities of CYP2B1/2 and 1A1,whereas it did not change the activities of CYP2A and 2E1,compared to that of the DEN group.CXB treatment for eight days did not produce a signif icant effect on enzymatic activity when compared to the NT group;however,when it was administered for prolonged times(CXB 32 d group) ,the enzymatic activities were increased in a similar pattern to those in the DEN+CXB group.The observed increase in the enzymatic activities in the DEN+CXB group was accompanied by an increase in the CYP2B1/2 protein levels;no changes were observed in the levels of CYP1A1.In vitro,CXB increased the denitrosation of DEN,a pathway of metabolic detoxification.The addition of SKF-525A,a preferential inhibitor of CYP2B,abrogated the denitrosation of DEN.CONCLUSION:These results suggest that the mechanism of action of CXB involves enhancement of the detoxif ication of DEN by an increasing denitrosation via CYP2B1/2. | Martha Estela Salcido-Neyoy Adolfo Sierra-Santoyo Olga Beltrán-Ramírez José Roberto Macías-Pérez Saúl Villa-Trevio | 2009 | World Journal of Gastroenterology2009，15，19： | 3 |
| 7 | Sex-specific effects of Eugenia punicifolia extract on gastric ulcer healing in rats显示文摘AIM To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia(HEEP) leaves on gastric ulcer healing.METHODS In this rat study involving males, intact(cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity.RESULTS Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males(52.44%), intact females(85.22%), and ovariectomized females(65.47%), confirming that HEEP accelerates the healing of acetic acidinduced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor(intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2(intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed.CONCLUSION In gastric ulcers, HEEP-induced healing(modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration. | Larissa Lucena Périco Vinícius Peixoto Rodrigues Rie Ohara Gabriela Bueno Vania Vasti Alfieri Nunes Raquel Cássia dos Santos Ana Carolina Lima Camargo Luis Antuio Justulin Joior Sérgio Faloni de Andrade Viviane Miranda Bispo Steimbach Luísa Mota da Silva Lúcia Regina Machado da Rocha Wagner Vilegas Catarina dos Santos Clélia Akiko Hiruma-Lima | 2018 | World Journal of Gastroenterology2018，24，38： | 3 |

| 12 | S-adenosyl-methionine decreases ethanol-induced apoptosis in primary hepatocyte cultures by a c-Jun N-terminal kinase activity-independent mechanism显示文摘AIM:To determine the role of c-Jun N-terminal kinase(JNK)activity in ethanol-induced apoptosis and themodulation of this signaling cascade by S-Adenosyl-methionine(AdoMet).METHODS:Primary hepatocyte cultures werepretreated with 100 μmol/L SP600125,a selective JNKinhibitor,1 mL/L DMSO or 4 mmol/L AdoMet and thenexposed to 100 mmo/L ethanol.Hepatocyte apoptosiswas determined by the TUNEL and DNA ladder assays.JNK activity and its inhibition by SP600125 and AdoMetwere determined by Western blot analysis of c-junphosphorylation and Bid fragmentation.SP600125 andAdoMet effects on the apoptotic signaling pathway weredetermined by Western blot analysis of cytochrome crelease and pro-caspase 3 fragmentation.The AdoMeteffect on glutathione levels was measured by Ellman'smethod and reactive oxygen species(ROS)generationby cell cytometry.RESULTS:The exposure of hepatocytes to ethanolinduced JNK activation,c-jun phosphorylation,Bidfragmentation,cytochrome c release and pro-caspase 3cleavage;these effects were diminished by SP600125,and caused a significant decrease in ethanol-inducedapoptosis(P<0.05).AdoMet exerted an antioxidanteffect maintaining glutathione levels and decreasing ROSgeneration,without a significant effect on JNK activity,and prevented cytochrome c release and pro-caspase 3cleavage. CONCLUSION:The JNK signaling cascade is a keycomponent of the proapoptotic signaling pathwayinduced by ethanol.JNK activation may be independentfrom ROS generation,since AdoMet which exertedantioxidant properties did not have a significant effect onJNK activity.JNK pathway modulator agents and AdoMetmay be components of promising therapies for alcoholicliver disease(ALD)treatment. | Maria del Pilar Cabrales-Romero Lucrecia Márquez-Rosado Samia FatteI-Fazenda Cristina Trejo-Solis Evelia Arce-Popoca Leticia Alemán-Lazarini Saúl Villa-Trevineo | 2006 | World Journal of Gastroenterology2006，12，12： | 2 |
