The relationship between therapeutic response and modifications of microRNA (miRNA) transcriptome in colorectal cancer (CRC) remains unknown. We investigated this issue by profiling the expression of 667 miRNAs in 2 human CRC cell lines, one sensitive and the other resistant to cetuximab (Caco-2 and HCT-116, respectively), through TaqMan real-time PCR.(More)
We report on two cases of myofibroblastoma (MFB) of the breast comprised predominantly of a mature fatty component, representing approximately three quarters of the entire tumour area. Both tumours consisted of a well-circumscribed lipomatous tumour mass containing dispersed nodular or irregularly shaped spindled cellular areas. The fatty component was(More)
Despite Wilms tumor 1 (WT1) protein was originally considered as a specific immunomarker of Wilms tumor, with the increasing use of immunohistochemistry, there is evidence that other tumors may share WT1 protein expression. This review focuses on the immunohistochemical profile of WT1 protein in the most common malignant tumors of children and adolescents.(More)
The human mesonephros is currently regarded as a simplified version of the foetal metanephros, primarily due to the close morphological resemblance between these two structures. The aim of the present study was to define whether human mesonephric and foetal metanephric nephrons share immunophenotypical traits in their corresponding structures (glomeruli,(More)
Extragastrointestinal stromal tumors (EGISTs) are a rare subgroup of gastrointestinal stromal tumors (GISTs), arising from outside the walls of gastrointestinal tubular organs. We report a case of an EGIST of the lesser omentum that represented a diagnostic challenge. Due to its atypical radiologic findings, it was preoperatively mistaken for pedunculated(More)
BACKGROUND The main cause of treatment failure and death in laryngeal squamous cell carcinoma is metastasis to the regional lymph nodes. The current clinical staging criteria fail to differentiate patients with occult metastasis from patients without metastasis. Identifying molecular markers of the disease might improve our understanding of the molecular(More)
Developmental expression of Wilms' tumor gene (WT1) and protein is crucial for cell proliferation, apoptosis, differentiation and cytoskeletal architecture regulation. Recently, a potential role of WT1 has been suggested in the development of neural tissue and in neurodegenerative disorders. We have investigated immunohistochemically the developmentally(More)
MiR-671-5p is encoded by a gene localized at 7q36.1, a region amplified in human glioblastoma multiforme (GBM), the most malignant brain cancer. To investigate whether expression of miR-671-5p were altered in GBM, we analyzed biopsies from a cohort of forty-five GBM patients and from five GBM cell lines. Our data show significant overexpression of(More)
BACKGROUND The clinical evolution of laryngeal squamous cell carcinoma (SCC) is undetectable with the current staging criteria. To more completely understand the biology of laryngeal SCC, we assessed the expression of the proteins B-cell-specific Moloney murine leukemia virus integration site 1 (BMI1) and p16. METHODS We assessed immunohistochemically the(More)
Hamartoma of the breast is a pseudotumoural lesion that does not usually pose diagnostic problems for the pathologist. Although atypical stromal cell (ASCs) can be encountered in several benign and malignant breast lesions, their occurrence in hamartoma has not been reported to date. The authors report a case of breast hamartoma containing numerous atypical(More)
