The vaccinia-related kinase (VRK) proteins are a new family with three members in the human kinome. The VRK1 protein phosphorylates several transcription factors and has been postulated to be involved in regulation of cell proliferation. In normal squamous epithelium, VRK1 is expressed in the proliferation area. Because VRK1 can stabilize p53, the(More)
BACKGROUND Head and neck squamous cell carcinoma (HNSCC) is a common human neoplasia, of poor prognosis and survival, which frequently displays Akt overactivation. Previously, we reported that mice expressing high levels of constitutively Akt activity (myrAkt) in oral epithelia develop lesions and tumors in the oral cavity. MATERIALS AND METHODS(More)
Head and neck squamous cell carcinoma (HNSCC) is a common human neoplasia with poor prognosis and survival that frequently displays Akt overactivation. Here we show that mice displaying constitutive Akt activity (myrAkt) in combination with Trp53 loss in stratified epithelia develop oral cavity tumors that phenocopy human HNSCC. The myrAkt mice develop oral(More)
The spleen is frequently involved in B-cell lymphomas other than splenic marginal zone lymphoma. Here we describe a series of follicular lymphoma (FL) cases diagnosed in the spleen, consisting of 32 patients who presented clinically with splenomegaly, and slight or no peripheral lymphadenopathy. The splenic specimen had a micronodular pattern, germinal(More)
AIMS To investigate the presence and prognostic relevance of KIT expression in paediatric renal tumours, and to determine whether receptor overexpression is associated with gene amplification and/or mutation. METHODS Immunohistochemistry without antigen retrieval for CD117 was carried out on tissue microarrays consisting of 274 Wilms' tumours, 13 clear(More)
Nodal marginal zone lymphoma (NMZL) is a small B-cell neoplasm whose molecular pathogenesis is still essentially unknown and whose differentiation from other small B-cell lymphomas is hampered by the lack of specific markers. We have analyzed gene expression, miRNA profile, and copy number data from 15 NMZL cases. For comparison, 16 follicular lymphomas(More)
Screening for germline mutations in breast cancer-associated genes BRCA1 and BRCA2 is indicated for patients with breast cancer from high-risk breast cancer families and influences both treatment options and clinical management. However, only 25% of selected patients test positive for BRCA1/2 mutation, indicating that additional diagnostic biomarkers are(More)
INTRODUCTION The identification and validation of biomarkers of chemotherapy sensitivity is critical in order to individualise therapy in breast cancer. We evaluated pathological complete response (pCR) to GAT, and its correlation with tumour biomarkers before and after neoadjuvant chemotherapy. MATERIALS AND METHODS Stage III (and stage II with T≥5 cm)(More)
PURPOSE Epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase overexpressed in a variety of human malignancies, against which targeted therapies have shown efficacy in lung and brain tumors. Clinical responses to EGFR inhibitors have been found to be highly dependent on the presence of activating mutations, whereas gene amplification,(More)
The combination of cisplatin and capecitabine was evaluated in patients with recurrent or unresectable squamous cell carcinoma of the head and neck (HNSCC), and outcome parameters were correlated with the expression of thymidine phosphorylase (TP), thymidilate syntetase (TS), vascular endothelial growth factor receptor (VEGFR) 1-3, and microvessel density(More)
