Immunohistochemical analyses of phosphatases in childhood B-cell lymphoma: Lower expression of PTEN and HePTP and higher number of positive cells for nuclear SHP2 in B-cell lymphoma cases compared to controls (2008)

Fridberg, Marie, Kjellström, Sofia, Anagnostaki, Lola, Skogvall, Ingela, Mustelin, Tomas, Wiebe, Thomas, ...

Although many pediatric B-cell lymphoma patients are being cured today, much is still unknown about the pathogenesis of this disease. Protein tyrosine phoshatases are involved in the control of...

K-rasmutations in sinonasal cancers in relation to wood dust exposure (2008)

Bornholdt, Jette, Hansen, Johnni, Steiniche, Torben, Dictor, Michael, Antonsen, Annemarie, Wolff, Henrik, ...

Abstract Background Cancer in the sinonasal tract is rare, but persons who have been occupationally exposed to wood dust have a substantially increased risk. It has been estimated that approximately...

COX-2 and p53 in human sinonasal cancer: COX-2 expression is associated with adenocarcinoma histology and wood-dust exposure. (2008)

Holmila, Reetta, Cyr, Diane, Luce, Danièle, Heikkilä, Pirjo, Dictor, Michael, Steiniche, Torben, ...

The causal role of wood-dust exposure in sinonasal cancer (SNC) has been established in epidemiological studies, but the mechanisms of SNC carcinogenesis are still largely unknown. Increased amounts...

The causal role of wood-dust exposure in sinonasal cancer (SNC) has been established in epidemiological studies, but the mechanisms of SNC carcinogenesis are still largely unknown. Increased amounts...

Midline carcinoma with t(15;19) and BRD4-NUTfusion oncogene in a 30-year-old female with response to docetaxel and radiotherapy (2006)

Engleson, Jens, Soller, Maria, Panagopoulos, Ioannis, Dahlén, Anna, Dictor, Michael, Jerkeman, Mats

Abstract Background Poorly differentiated midline carcinoma with a translocation between chromosomes 15 and 19, i.e. t(15;19), has been recognized as a distinct clinical entity for over a decade....

Karyotypic heterogeneity and clonal evolution in squamous cell carcinomas of the head and neck. (2002)

Jin, Charlotte, Jin, Yuesheng, Wennerberg, Johan, Akervall, Jan, Dictor, Michael, Mertens, Fredrik

Head and neck squamous cell carcinomas (HNSCC) are often characterized by complex karyotypic changes, and a substantial proportion of the reported tumors have shown intratumor heterogeneity in the...

Chromosomal translocations involving 11q13 contribute to cyclin D1 overexpression in squamous cell carcinoma of the head and neck. (2002)

Akervall, Jan, Borg, Ake, Dictor, Michael, Jin, Charlotte, Jin, Yuesheng, Tanner, Minna, ...

CCND1 amplification results in cyclin D1 overexpression. However, other unidentified genetic mechanisms contribute to enhanced gene expression. In the present study, 32 squamous cell carcinoma of the...

Evaluation of the tissue microarray technique for immunohistochemical analysis in rectal cancer. (2002)

Fernebro, Eva, Dictor, Michael, Bendahl, Pär-Ola, Fernö, Mårten, Nilbert, Mef

BACKGROUND: Immunohistochemical staining for tumor-associated proteins is widely used for the identification of novel prognostic markers. Recently, a tissue-conserving, high-throughput technique,...

Mantle cell lymphomas express a distinct genetic signature affecting lymphocyte trafficking and growth regulation as compared with subpopulations of normal human B cells. (2002)

Ek, Sara, Högerkorp, Carl-Magnus, Dictor, Michael, Ehinger, Mats, Borrebaeck, Carl A K

Differential gene expression analysis, using high-density microarray chips, demonstrated 300-400 genes to be deregulated in mantle cell lymphomas (MCLs) compared with normal B-cell populations. To...

Cytogenetic abnormalities in a hemangiopericytoma of the spleen. (2002)

Hallén, Magnus, Parada, Luis A, Gorunova, Ludmila, Pålsson, Birger, Dictor, Michael, Johansson, Bertil

To date, only 16 cytogenetically abnormal hemangiopericytomas (HP) have been reported. Despite this low number, some characteristic karyotypic features have already emerged: most HP are near-diploid...

Strong lymphoid nuclear expression of SOX11 transcription factor defines lymphoblastic neoplasms, mantle cell lymphoma and Burkitt’s lymphoma

Dictor, Michael, Ek, Sara, Sundberg, Maria, Warenholt, Janina, György, Czabafy, Sernbo, Sandra, ...

The authors surveyed lymphomas to determine the range of expression of the mantle cell lymphoma- associated SOX11 transcription factor and its relation to cyclin D1. In addition to mantle cell...
