Objective To investigate the expression of tumor growth tactor ?1 (TGF-?1) and p27 in gallbladder carcinoma and their relation to the development of the carcinoma. Methods The expression of TGF-?1 and p27 in 36 cases of gallbladder carcinoma was detected by SP immunohistochemical staining. Twenty cases of chronic cholecystitis were collected as control. Results The positive rate of TGF-?1 (63.9%) was higher than that of the control (10.0%), P

Objective To study the relation between expressions of transforming growth factor ?1 (TGF-?1), transforming growth factor receptor type Ⅰ (T?RⅠ) and cell proliferation, cell cycle in gallbladder carcinomas, to disclose the mechanism of TGF-?1 and T?RⅠin the gallbladder carcinogenesis,and to evaluate their values in the prognosis of gallbladder carcinomas. Methods Thirty five gallbladder carcinomas age (57.94? 4.61) years, 14 male cases and 21 female cases comprised 32 adenocarcinomas, 2 adenosquamous carcinoma and 1 squamous cell carcinomas. Formalin fixed, paraffin embedded sections from gallbladder carcinomas were immunostained with TGF-?1, T?RⅠ, PCNA, cyclin E antibodies by immunochemical assays. Gallbladder adenoma and chronic cholecystitis were collected as non-malignant controls. Patients of gallbladder carcinomas were followed up. Results Positive immunostaining rate of TGF-?1 was 57.14% in gallbladder carcinomas, which was significantly higher than that in gallbladder adenomas and chronic cholecystitis (P
