Pancreatic ductal adenocarcinoma (PDAC) is one of the most common causes of cancer related death. Despite the advances in understanding of the molecular pathogenesis, pancreatic cancer remains a major unsolved health problem. Overall, the 5-year survival rate is less than 5% demonstrating the insufficiency of current therapies. Most cytotoxic therapies(More)
Pancreatic ductal adenocarcinoma (PDAC) is characterized by a dismal prognosis and no effective conservative therapy exists. Although the F-box protein S-phase kinase associated protein 2 (SKP2) is highly expressed and regulates cell cycle progression in PDAC, alternative SKP2 functions in PDAC are unknown. Using RNA interference we now demonstrate that(More)
The phosphoinositide-3-kinase (PI3K)/AKT signaling pathway controls fundamental processes of cancer cell biology like proliferation and cell survival. The PI3K/AKT pathway is activated in pancreatic ductal adenocarcinoma (PDAC) cells. The molecular mechanisms linking PI3K signaling to the cell cycle machinery in PDAC cells are not investigated in detail.(More)
Pancreatic cancer is one of the most common causes of cancer death in western civilization. The five-year survival rate is below 1% and of the 10% of patients with resectable disease only around one-fifth survives 5 years. Survival rates have not changed much during the last 20 years, demonstrating the inefficacy of current available therapies. To improve(More)
Epidemiological and experimental data demonstrate, that inflammation contributes significantly to pancreatic carcinogenesis. IL1beta, a pleiotropic cytokine produced by inflammatory cells and tumor cells, promotes cancer progression. Single nucleotide polymorphisms (SNPs) of the IL1beta promoter were found to be associated with an increased risk for certain(More)
Pancreatic ductal adenocarcinoma is a dismal disease with a median survival of less than 6 months and an overall 5-year survival rate less than 1%. This bad prognosis is due to early lymphatic and hematogenic dissemination. Effective therapies for locally advanced or metastatic tumors are very limited and curatively resected patients experience relapse in(More)
OBJECTIVE Histone deacetylases (HDACs) have been linked to cell cycle control in various models, involving regulation of the cyclin-dependent kinase inhibitor p27(Kip1). RESULTS Here, we demonstrate that HDAC inhibition by trichostatin A reduces S-phase kinase-associated protein 2 mRNA and protein abundance. Furthermore, in contrast to HDAC1, recruited to(More)
Primary heart tumors are an extremely rare oncological entity with primary cardiac sarcomas usually representing 20% of all primary cardiac tumorous lesions [Shanmugam: Eur J Cardiothorac Surg 2006;29: 925-932; Orlandi et al.: J Thorac Oncol 2010;5: 1483-1489]. Angiosarcoma is the most prevalent histology and despite a multidisciplinary approach tends to(More)
Die Ursache für eine Magenausgangsstenose kann benigner und maligner Genese sein. Bei der hier vorgestellten Patientin war nach der weiterführenden Diagnostik mittels CT und Knochenmarkbiopsie die CT wegweisend für die definitive Diagnosestellung und Therapieplanung. Gastric outlet obstructions can be of benign or malignant origin. In the case of the female(More)
PURPOSE OF REVIEW Sarcoma is a basket term for mesenchymal tumors for which more than 75 genetically and histologically distinct subtypes are recognized. Therapeutic progress has largely been achieved with classical chemotherapeutic drugs that were tested in empirical clinical trials. However, outcome in metastatic patients remains poor and with few(More)
