1Hepatitis B and C virus-induced hepatitis: Apoptosis, autophagy, and unfolded protein response显示文摘AIM: To investigate the co-incidence of apoptosis, autophagy, and unfolded protein response(UPR) in hepatitis B(HBV) and C(HCV) infected hepatocytes.METHODS: We performed immunofluorescence confocal microscopy on 10 liver biopsies from HBV and HCV patients and tissue microarrays of HBV positive liver samples. We used specific antibodies for LC3β, cleaved caspase-3, BIP(GRP78), and XBP1 to detect autophagy, apoptosis and UPR, respectively. AntiHCV NS3 and anti-HBs antibodies were also used to confirm infection. We performed triple blind counting of events to determine the co-incidence of autophagy(LC3β punctuate), apoptosis(cleaved caspase-3), and unfolded protein response(GRP78) with HBV and HCV infection in hepatocytes. All statistical analyses were performed using SPSS software for Windows(Version 16 SPSS Inc, Chicago, IL, United States). P-values < 0.05 were considered statistically significant. Statistical analyses were performed with Mann-Whitney test to compare incidence rates for autophagy, apoptosis, and UPR in HBV- and HCV-infected cells and adjacent noninfected cells.RESULTS: Our results showed that infection of hepatocytes with either HBV and HCV induces significant increase(P < 0.001) in apoptosis(cleavage of caspase-3), autophagy(LC3β punctate), and UPR(increase in GRP78 expression) in the HCV- and HBVinfected cells, as compared to non-infected cells of the same biopsy sections. Our tissue microarray immunohistochemical expression analysis of LC3β in HBV^(Neg) and HBV^(Pos) revealed that majority of HBVinfected hepatocytes display strong positive stainingfor LC3β. Interestingly, although XBP splicing in HBVinfected cells was significantly higher(P < 0.05), our analyses show a slight increase of XBP splicing was in HCV-infected cells(P > 0.05). Furthermore, our evaluation of patients with HBV and HCV infection based on stage and grade of the liver diseases revealed no correlation between these pathological findings and induction of apoptosis, autophagy, and UPR.CONCLUSION: The results of this study indicate that HCV and HBV infection activates apoptosis, autophagy and UPR, but slightly differently by each virus. Further studies are warranted to elucidate the interconnections between these pathways in relation to pathology of HCV and HBV in the liver tissue.Behzad Yeganeh Adel Rezaei Moghadam Javad Alizadeh Emilia Wiechec Seyed Moayed Alavian Mohammad Hashemi Bita Geramizadeh Afshin Samali Kamran Bagheri Lankarani Martin Post Payam Peymani Kevin M Coombs Saeid Ghavami 2015World Journal of Gastroenterology2015,21,47:13
2Oral manifestation in inflammatory bowel disease:A review显示文摘Inflammatory bowel diseases(IBDs),including Crohn’s disease(CD)and ulcerative colitis,not only affect the intestinal tract but also have an extraintestinal involvement within the oral cavity.These oral manifestations may assist in the diagnosis and the monitoring of disease activity,whilst ignoring them may lead to an inaccurate diagnosis and useless and expensive workups.Indurated tag-like lesions,cobblestoning,and mucogingivitis are the most common specific oral findings encountered in CD cases.Aphthous stomatitis and pyostomatitis vegetans are among non-specific oral manifestations of IBD.In differential diagnosis,side effects of drugs,infections,nutritional deficiencies,and other inflammatory conditions should also be considered.Treatment usually involves managing the underlying intestinal disease.In severe cases with local symptoms,topical and/or systemic steroids and immunosuppressive drugs might be used.Kamran B Lankarani Gholam Reza Sivandzadeh Shima Hassanpour 2013World Journal of Gastroenterology2013,19,46:10

5COVID-19 infection and liver injury:Clinical features,biomarkers,potential mechanisms,treatment,and management challenges显示文摘It is hypothesized that liver impairment caused by coronavirus disease 2019(COVID-19)infection might play a central role in severe clinical presentations.Liver injury is closely associated with severe disease and,even with antiviral drugs,have a poor prognosis in COVID-19 patients.In addition to the common hepatobiliary disorders caused by COVID-19,patients with pre-existing liver diseases demand special considerations during the current pandemic.Thus,it is vital that upon clinical presentation,patients with concurrent pre-existing liver disease associated with metabolic dysfunction and COVID-19 be managed properly to prevent liver failure.Careful monitoring and early detection of liver damage through biomarkers after hospitalization for COVID-19 is underscored in all cases,particularly in those with pre-existing metabolic liver injury.The purpose of this study was to determine most recent evidence regarding causality,potential risk factors,and challenges,therapeutic options,and management of COVID-19 infection in vulnerable patients with pre-existing liver injury.This review aims to highlight the current frontier of COVID-19 infection and liver injury and the direction of liver injury in these patients.Gholam Reza Sivandzadeh Hassan Askari Ali Reza Safarpour Fardad Ejtehadi Ehsan Raeis-Abdollahi Armaghan Vaez Lari Mohammad Foad Abazari Firoozeh Tarkesh Kamran Bagheri Lankarani 2021World Journal of Clinical Cases2021,9,22:5

7Promoter polymorphism of transforming growth factor-β1 gene and ulcerative colitis显示文摘AIM: To elucidate the possible difference in two promoter polymorphisms of the transforming growth factor-β1 (TGF-β1) gene (-800G > A, -509C > T) between ulcerative colitis (UC) patients and normal subjects.METHODS: A total of 155 patients with established ulcerative colitis and 139 normal subjects were selected as controls. Two single nucleotide polymorphisms within the promoter region of TGF-β1 gene (-509C > T and -800G > A) were genotyped using PCR-RFLP. RESULTS: There was a statistically significant difference in genotype and allele frequency distributions between UC patients and controls for the -800G > A polymorphism of the TGF-β1 gene (P < 0.05). The frequency of the TGF-β1 gene polymorphism at position -800 showed that the AA genotype and the allele A frequencies significantly differed between the patients and healthy controls (P < 0.05). At position -509, there was no statically significant difference in genotype and allele frequency between the patients and control subjects.CONCLUSION: The results of our study indicate that there is a significant difference in both allele and genotype frequency at position -800G > A of TGF-β1 gene promoter between Iranian patients with UC and normal subjects.B Tamizifar KB Lankarani S Naeimi M Rismankar Zadeh A Taghavi A Ghaderi 2008World Journal of Gastroenterology2008,14,2:4
