Expression of Ki-67, p53 and VEGF in pediatric neuroblastoma.
BACKGROUND Neuroblastoma (NB), is a neuroectodermal tumor derived from neural crest cells, and it is the second most common pediatric malignant tumor. The biological and clinical behavior of NB is very heterogeneous. This study was conducted to evaluate the expression of Ki-67, p53 and VEGF markers in tissues obtained from NB patients with different histologic types and stage. MATERIALS AND M...
متن کاملKi-67 and p53 expression in ileal pouches.
Development of dysplastic lesions that may potentially lead to cancer is sometimes reported within the ileal pouches. Dysplasia is in turn associated with increased expression of proliferation indices. The goal of this study was to evaluate the mitotic activity and possible expression of p53 in the epithelium within the ileal pouches in patients with chronic ulcerative colitis. The study invol...
متن کاملevaluation of ki-67 antigen and protein p53 expression in orthokratinized and parakratinized odontogenic keratocyst
statement of problem: odontogenic keratocysts (okc) make up 10-12% of all developmental cysts with dental origin. okcs are classified into parakeratotic and orthokeratotic types, with completely different clinical features. in order to investigate biological behavior of okcs, an immunohistochemical study was designed, using ki-67 antigen as proliferation marker and p53 protein as tumor suppress...
متن کاملimmunohistochemical expression of p53 and ki-67 in different histopathological variants of basal cell carcinoma
background : basal cell carcinoma is the most common form of skin cancer in men. increased marker expressions of apoptosis and cell proliferation have been found in the majority of basal cell carcinomas. our purpose was to determine whether any correlation between immunohistochemical expressions of p53 and ki-67 in different histopathological variants of basal cell carcinoma and patient’s age, ...
متن کاملexpression of p53 and ki-67 proteins in a odontogenic keratocysts
abstract introduction. p53 has been known as a tumor suppressor gene and also ki-67 is a cell cycle regulator. the aim of present study was to investigate p53 and ki-67 protein expression in the epithelial lining of odontogenic cysts and its correlation with their biologic behavior and the degree of inflammation within the cyst wall. methods. p53 and ki-67 immunoreactivity in 58 odontogenic cys...
