Collagenase-3 (MMP-13) is a matrix metalloproteinase recently identified on the basis of differential expression in normal breast tissues and in breast carcinoma. To date, collagenase-3 expression has been reported only in breast carcinomas and in articular cartilage of arthritic patients; the presence and possible implication of this enzyme in the(More)
The JC12 monoclonal antibody recognizes a previously unknown nuclear protein that showed a restricted distribution in normal tonsil and was also overexpressed in a subset of diffuse large B-cell lymphomas. Using this reagent, we expression cloned cDNAs encoding its antigenic target and identified this protein as a novel putative transcription factor, FOXP1.(More)
Despite the widespread use of sentinel lymph node (SLN) biopsy in breast cancer patients, some controversy exists about the correct management of extra-axillary nodes, especially those located in the internal mammary chain. The aim of this study was to evaluate the incidence of SLNs in this region, calculate the lymphoscintigraphic and surgical detection(More)
Recent findings indicate that the expression of the beta-catalytic subunit of the mitochondrial H+-ATP synthase (beta-F1-ATPase) is depressed in liver, kidney and colon carcinomas, providing further a bioenergetic signature of cancer that is associated with patient survival. In the present study, we performed an analysis of mitochondrial and glycolytic(More)
PRAD-1 is a putative oncogene localized on chromosome 11q13 which encodes cyclin D1, a novel cyclin involved in cell cycle regulation. Amplification of this gene has recently been reported in several human tumors including breast and head and neck carcinomas. In this study we have analyzed the presence of PRAD-1/cyclin D1 gene amplification and mRNA(More)
We have examined the presence of p16MTS1/CDK4I gene deletions, mutations and methylation status, and 9p21-23 deletions in a series of 46 squamous cell carcinomas of the larynx and paired normal mucosa previously characterized for cyclin D1 gene amplification and overexpression. pRb expression was also examined by immunohistochemistry. p16MTS1/CDK4I(More)
One of the main properties of cancer cells is their increased and deregulated proliferative activity. It is now well known that abnormalities in many positive and negative modulators of the cell cycle are frequent in many cancer types, including breast carcinomas. Abnormalities such as defective function of the retinoblastoma gene and cyclin-dependent(More)
Idiopathic chondrolysis of the hip is characterized by the destruction of the articular cartilage due to an unknown cause, principally affecting women during adolescence and producing premature degeneration of the hip. Twelve cases (11 patients) were reviewed at our hospital, with an average follow-up period of 13.2 years, during which a clinical and(More)
BACKGROUND & AIMS Galectins are beta-galactoside-binding proteins possibly involved in tumor progression. The aim of this study was to determine the pattern of galectin 3 and galectin 1 expression and involvement in colorectal cancer progression. METHODS Galectin 3 expression was examined immunohistochemically in 39 samples of normal mucosae, 25 adenomas,(More)
The authors reviewed a series of 110 surgical specimens of primary non-small cell lung carcinomas from the Department of Pathology at the Hospital Clinic, University of Barcelona Medical School, between 1987 and 1997. The sample included 25 squamous cell carcinomas, 60 adenocarcinomas, 14 large cell carcinomas, and 11 neuroendocrine tumors. Electron(More)
