J. pediatr. (Rio J.); 94 (4), 2018
Abstract Objective: To evaluate the clinical features associated with adrenocortical hormone overexpression and familial cancer profiling as potential markers for early detection of adrenocortical tumors in children from South and Southeast Brazil. Methods: The clinical manifestations and anthropometri...

Atypical Leiomyomas of the Uterus: A Clinicopathologic Study of 54 Cases and an Immunohistochemical Analysis of Ki-67 and p53

West Indian med. j; 67 (1), 2018
ABSTRACT Objective: Uterine atypical leiomyomas (ALs) are extremely rare and occur in an age group almost one decade earlier than that for leiomyosarcomas. According to the literature, extensive clinicopathologic studies on ALs were limited to only two studies (2, 8). Atypical leiomyomas of the uterus a...

Immunohistochemical WWOX expression and association with angiogenesis, p53 expression, cell proliferation and clinicopathological parameters in cervical cancer

Abstract Objective The current study evaluated the expression of WW domain-containing oxidoreductase (WWOX), its association with clinicopathological features and with p53, Ki-67 (cell proliferation) and CD31 (angiogenesis) expression in patients with invasive cervical squamous cell carcinoma (ICSCC). ...

Introdução: Melanoma cutâneo tem etiologia multifatorial. BRAF, NRAS, KIT, PTEN e TP53 são importantes genes envolvidos na patogênese do melanoma. Objetivo: Caracterizar o perfil clinicopatológico e molecular do melanoma cutâneeo primário no Estado do Ceará, Brasil. Metodologia: Dados demográfi...

Oridonin induces growth inhibition and apoptosis in human gastric carcinoma cells by enhancement of p53 expression and function

Braz. j. med. biol. res; 51 (12), 2018
The tumor suppressive role of oridonin, an active compound extracted from Rabdosia rubescens, has been proven in several gastric cancer (GC) cell lines. The present study aimed to evaluate the effect of oridonin on another GC cell line, SNU-216, and explore the potential mechanisms. The viable cell numbe...

Eixo XPC-P53-H202 e disfunção mitocondrial: qual é o fator central?

A ausência de XPC, uma proteína canonicamente envolvida em reparo de DNA por excisão de nucleotídeos, está associada a vários fenótipos característicos de disfunção mitocondrial como o desequilíbrio entre os complexos da cadeia transportadora de elétrons (CTE), redução no consumo de oxigên...

Icariin reduces human colon carcinoma cell growth and metastasis by enhancing p53 activities

Braz. j. med. biol. res; 51 (10), 2018
Icariin has been reported to possess high anticancer activity. Colon carcinoma is one of the leading causes of cancer-related mortality worldwide. Here, the anticancer activity of icariin against HCT116 colon carcinoma cells and the possible underlying mechanism were studied. The trypan blue staining ass...

Improving adenoviral vectors and strategies for prostate cancer gene therapy

Clinics; 73 (supl.1), 2018
Gene therapy has been evaluated for the treatment of prostate cancer and includes the application of adenoviral vectors encoding a suicide gene or oncolytic adenoviruses that may be armed with a functional transgene. In parallel, versions of adenoviral vector expressing the p53 gene (Ad-p53) have been te...

Caracterização dos fenótipos de mucina podem prever a recorrência do câncer gástrico precoce após a mucosectomia endoscópica

Arq. gastroenterol; 54 (4), 2017
ABSTRACT BACKGROUND: Endoscopic mucosal resection is still considered an accepted treatment for early gastric cancer for selected cases. Histopathologic criteria for curative endoscopic resection are intramucosal well-differentiated adenocarcinoma, lateral and deep margins free of tumor, no histological...
