(英) The role of activation-induced cytidine deaminase expression in gastric adenocarcinoma.
(英) Gastric adenocarcinoma is one of the most common malignant tumors and the leading cause of malignancy-related death worldwide. Studies have reported overexpression of activation-induced cytidine deaminase (AID) and protein kinase c iota (PKCi) proteins showing involvement in the regulation of carcinogenesis. In the present study, we investigated the expression of AID and PKCi in patients with gastric adenocarcinoma and determined the correlation between these proteins. This study was conducted between September 2009 and September 2010 on a total of 59 patients with gastric adenocarcinoma at the Tokushima University Hospital. AID, PKCi and mutated p53 protein expressions were evaluated by immunohistochemistry in gastric adenocarcinoma. High AID and PKCi expression was significantly (p<0.05) associated with poorly-differentiated gastric adenocarcinoma. In addition, PKCi expression was significantly correlated with clinicopathological findings such as a lymph node metastasis, and venous and lymphatic invasion (p<0.05). Furthermore, AID expression was significantly correlated with PKCi and mutated p53 protein expression in gastric adenocarcinoma (p<0.05). High AID and PKCi expressions were significantly correlated with poorly-differentiated gastric adenocarcinoma.
