Quantitative promoter methylation analysis of multiple cancer-related genes in renal cell tumors (2007)

Costa, Vera L, Henrique, Rui, Ribeiro, Franclim R, Pinto, Mafalda, Oliveira, Jorge, Lobo, Francisco, ...

Abstract Background Aberrant promoter hypermethylation of cancer-associated genes occurs frequently during carcinogenesis and may serve as a cancer biomarker. In this study we aimed at defining a...

Comparison of chromosomal and array-based comparative genomic hybridization for the detection of genomic imbalances in primary prostate carcinomas (2006)

Ribeiro, Franclim R, Henrique, Rui, Hektoen, Merete, Berg, Marianne, Jerónimo, Carmen, Teixeira, Manuel R, ...

Abstract Background In order to gain new insights into the molecular mechanisms involved in prostate cancer, we performed array-based comparative genomic hybridization (aCGH) on a series of 46...

No significant role for beta tubulin mutations and mismatch repair defects in ovarian cancer resistance to paclitaxel/cisplatin (2005)

Mesquita, Bárbara, Veiga, Isabel, Pereira, Deolinda, Tavares, Ana, Pinto, Isabel M, Pinto, Carla, ...

Abstract Background The mechanisms of chemoresistance in ovarian cancer patients remain largely to be elucidated. Paclitaxel/cisplatin combination is the standard chemotherapeutic treatment for this...

The loss of NKX3.1 expression in testicular – and prostate – cancers is not caused by promoter hypermethylation (2005)

Lind, Guro E, Skotheim, Rolf I, Fraga, Mario F, Abeler, Vera M, Henrique, Rui, Saatcioglu, Fahri, ...

Abstract Background Recent studies have demonstrated that the NKX3.1 protein is commonly down-regulated in testicular germ cell tumors (TGCTs) and prostate carcinomas. The homeobox gene NKX3.1 maps...

Molecular cytogenetic characterization of proximal-type epithelioid sarcoma (2004)

Modena, Piergiorgio, Pedeutour, Florence, Teixeira, Manuel R, Facchinetti, Federica, ...

Proximal-type epithelioid sarcoma is a recently described soft-tissue tumor that is distinguished from conventional-type epithelioid sarcoma by a far more aggressive clinical course, frequent...

Genome characteristics of primary carcinomas, local recurrences, carcinomatoses, and liver metastases from colorectal cancer patients (2004)

Diep, Chieu B, Teixeira, Manuel R, Thorstensen, Lin, Wiig, Johan N, Eknæs, Mette, Nesland, Jahn M, ...

Abstract Background Colorectal cancer (CRC) is one of the most common causes of cancer-related deaths in the Western world, and despite the fact that metastases are usually the ultimate cause of...

Distinct patterns of KRAS mutations in colorectal carcinomas according to germline Mismatch Repair defects and hMLH1 methylation status (2004)

Oliveira, Carla, Westra, Jantine L, Arango, Diego, Ollikainen, Miina, Domingo, Enric, Ferreira, Ana, ...

In sporadic colorectal tumours the BRAFV600E is associated with microsatellite instability (MSI-H) and inversely associated to KRAS mutations. Tumours from HNPCC patients carrying germline mutations...

Telomerase Activity and Genetic Alterations in Primary Breast Carcinomas

Papadopoulou, Anna, Trangas, Theoni, Teixeira, Manuel R, Heim, Sverre, Dimitriadis, Euthimios, Tsarouha, Haroula, ...

It has been proposed that the structural and numerical chromosome abnormalities recorded in breast cancer could be the result of telomere dysfunction and that telomerase is activated de novo to...

Evaluation of Breast Cancer Polyclonality by Combined Chromosome Banding and Comparative Genomic Hybridization Analysis1

Teixeira, Manuel R, Tsarouha, Haroula, Kraggerud, Sigrid M, Pandis, Nikos, Dimitriadis, Euthymios, Andersen, Johan A, ...

Cytogenetically unrelated clones have been detected by chromosome banding analysis in many breast carcinomas. Because these karyotypic studies were performed on short-term cultured samples, it may be...
