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). ...

Lung cancer biopsy: Can diagnosis be changed after immunohistochemistry when the H&E-Based morphology corresponds to a specific tumor subtype?

Clinics; 73 (), 2018
OBJECTIVES: Advancements in non-small cell lung cancer treatment based on targeted therapies have made the differentiation between adenocarcinoma and squamous cell carcinoma increasingly important. Pathologists are challenged to make the correct diagnosis in small specimens. We studied the accuracy of an...

Detection of sputum cofilin-1 as indicator of malignancy

Braz. j. med. biol. res; 51 (8), 2018
Cofilin-1 (CFL1), a small protein of 18 kDa, has been studied as a biomarker due to its involvement in tumor cell migration and invasion. Our aim was to evaluate CFL1 as an indicator of malignancy and aggressiveness in sputum samples. CFL1 was analyzed by ELISA immunoassay in the sputum of 73 lung cancer...

Expression of urokinase-type plasminogen activator and its receptor in squamous cell carcinoma of the oral tongue

Abstract Urokinase-type plasminogen activator (uPA) and its receptor (uPAR) act in the proteolysis of basement membrane and extracellular matrix structures, facilitating tumor invasion. The purpose of this study was to evaluate the relationship between these proteins and clinicopathological parameters in...

Análise in situ de proteínas diferencialmente expressas em carcinomas epidermoides penianos por espectrometria de massas utilizando Matrix-Assisted Laser Desorption/Ionization (MALDI)

O carcinoma de pênis (CaPe) corresponde a uma doença maligna mutilante do homem. É mais frequente em regiões economicamente desprivilegiadas, como o Norte/Nordeste do Brasil, onde frequentemente é diagnosticado como doença mais avançada. Assim, novos marcadores diagnósticos, prognósticos e predi...
