Emerging evidence indicates that peroxisome proliferator-activated receptor γ (PPARγ) and DNA methyltransferases (DNMTs) play a role in carcinogenesis. In this study we aimed to evaluate the expression of PPARγ, DNMT1, and DNMT3B and their correlation with clinical-pathological features in patients with pancreatic cancer (PC), and to define the effect of PPARγ activation on DNMTs expression in ...
PURPOSE Cholangiocarcinomas (CC) are associated with poor survival, but diagnostic markers and therapeutic targets have not yet been elucidated. We previously found aberrant expression of L1 cell adhesion molecule in intrahepatic CC and a role for L1 in the progression of intrahepatic CC. Here, we analyzed L1 expression in extrahepatic CC (ECC) and evaluated its prognostic significance. EXPER...
Gastric carcinosarcoma is a rare cancer of adults with poor prognosis compared with other gastric malignancies. To the best of our knowledge, the present report is the first case of gastric carcinosarcoma with chondroblastic differentiation in Iran. A 63-year-old man with epigastric pain was admitted to the surgery department. Abdominopelvic CT-scan showed a hypodense mass lesion in distal gast...
OBJECTIVE To detect immunohistochemically the N-cadherin expression in different types of benign and malignant salivary gland tumors in an attempt to note any possible correlation to their development, stage and invasive properties. MATERIALS AND METHODS N-cadherin expression was examined in tissue specimens from 49 salivary gland tumors including: pleomorphic adenomas (4), Warthin's tumors (...
