The BRCA/Fanconi anemia (FA) pathway plays a key role in the repair of DNA double strand breaks. We focused on this pathway to clarify chemoresistance mechanisms in biliary tract cancer (BTC). We also investigated changes in the CD24(+)/44(+) population that may be involved in chemoresistance, as this population likely includes cancer stem cells. We used three BTC cell lines to establish gemcit...
One 3D Cu(II)-based metal-organic framework {[Cu3(tmpa)2(1,2,3-btc)2(H2O)2].14H2O.2DMF}n (Cu(tmpa)) (tmpa = tris(4-(2-methyl-1H-imidazole-1-yl)phenyl)amine, 1,2,3-H3btc 1,2,3-benzenetricarboxylic acid) was prepared by hydrothermal method and characterized. Cu(tmpa) exhibits (3,3,4)-connected topology showing point symbol of (6·8·9)2(6·8·10)2(62·82·102). The heterostructural Cu(tmpa)/CN compo...
BACKGROUND Evidence on associations between self-reported diabetes mellitus, diabetes duration, age at diabetes diagnosis, insulin treatment, and risk of biliary tract cancer (BTC) and hepatocellular carcinoma (HCC), independent of general and abdominal obesity is scarce. PATIENTS AND METHODS We conducted a prospective analysis in the EPIC-cohort study among 363 426 participants with self-rep...
BACKGROUND Optimal chemotherapy for advanced biliary tract cancer (BTC) is yet to be defined. We carried out this study to evaluate the efficacy and toxicity of combination chemotherapy with S-1 and cisplatin in metastatic or relapsed BTC. PATIENTS AND METHODS Patients with pathologically proven BTC were eligible. The chemotherapy regimen consisted of S-1 (40 mg/m(2) p.o. b.i.d. from D1-14) a...
Biliary tract cancer (BTC) is a highly malignant cancer. BTC exhibits a low response rate to cisplatin (CDDP) treatment, and therefore, an understanding of the mechanism of CDDP resistance is urgently needed. Here, we show that BTC cells develop CDDP resistance due, in part, to upregulation of myeloid cell leukemia 1 (Mcl-1). Phenylethyl isothiocyanate (PEITC), a natural compound found in water...
در این مقاله با روشی ساده و ملایم ترکیبات 5،1-بنزودی آزپین با استفاده از تراکم مشتقات اورتو فنیلن دی آمین و کتون های خطی یا حلقوی در مجاورت مقادیر کاتالیزوری از چارچوب فلز-آلی نانوحفره Zn3(BTC)2 در حلال اتانول و دمای50 درجه سانتیگراد سنتز شدند. تمام محصولات با بازدههای بالا (%95-86) بهدست آمدند. چارچوب فلز-آلی نانوحفره Zn3(BTC)2 به کار برده شده، دارای مزایایی از جمله غیرسمی بودن، پایدار بودن در...
PURPOSE To investigate a rationale of pancreatobiliary cancers, thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD) concentrations in cancer tissues were evaluated. PATIENTS AND METHODS Twenty-nine patients with pancreatic cancer (PC) and 43 with biliary tract cancer (BTC; 27 cases of bile duct cancer, 8 of gallbladder cancer and 8 of cancer of the papillary area) were include...
Currently, there is no validated therapeutic target for biliary tract cancer (BTC). This study aimed to investigate the pre-clinical and clinical implication of HER2 as a therapeutic target in BTC. We established two novel HER2-amplified BTC cell lines, SNU-2670 and SNU-2773, from gallbladder cancer patients. SNU-2670 and SNU-2773 cells were sensitive to trastuzumab, dacomitinib, and afatinib c...
