Collagenase-3 (matrix metalloproteinase 13; MMP-13) is a novel matrix metalloproteinase, the expression of which to date has only been detected in human breast carcinoma tissue and osteoarthritic cartilage. Here, we show that MMP-13 transcripts are expressed by human HaCaT keratinocytes but not by primary human epidermal keratinocytes. The levels of MMP-13(More)
Heat shock transcription factors (HSFs) are generally known as regulators of cellular stress response. The mammalian HSF1 functions as a classical stress factor, whereas HSF2 is active during certain developmental processes, including embryogenesis and spermatogenesis. In the present study, we examined HSF2 expression at specific stages of the rat(More)
The prognostic impact of the tumor microenvironment in diffuse large B-cell lymphoma has not been systematically assessed. We analyzed mRNA and antigen expression of monocytes, macrophages, lymphocytes, dendritic and natural killer cells in pretreatment tumor samples of patients with high-risk diffuse large B-cell lymphoma using gene expression microarray(More)
A cell surface proteoglycan, syndecan-1, has been shown to participate in the maintenance of the epithelial cell morphology. A point mutated activated c-Ha-ras gene under the control of the glucocorticoid inducible MMTV-LTR promoter was transfected into the mouse mammary epithelial cell line, NOG-8. The NOG-8 ras cells were used to study changes in(More)
PURPOSE Tumor-associated macrophage (TAM) content predicts survival in follicular lymphoma (FL) patients treated with chemotherapy. The aim of this study was to determine how combination of rituximab with chemotherapy influences TAM-associated clinical outcome. EXPERIMENTAL DESIGN Expression of a macrophage marker, CD68, was determined(More)
UNLABELLED Based on small single-centre series, the risk of invasive fungal infections (IFI) has been considered small in autologous stem cell transplant (ASCT) recipients. PURPOSE To analyse epidemiological and clinical features of (IFI) among ASCT recipients in Finland 1990-2001. PATIENTS During the study period, 1188 adult patients received high-dose(More)
The two MAP kinases JNK and ERK direct distinct cellular activities even though they share a number of common substrates, including several transcription factors. Here we have compared JNK and ERK signalling during PC12 cell differentiation and investigated how activation of c-Jun by the MAPKs contributes to this cellular response. Exposure to nerve growth(More)
Gene expression profiling studies initially enabled diffuse large B-cell lymphoma to be divided into germinal center and activated B-cell-like subtypes, which define high- and low-risk patient groups when treated with chemotherapy. Attempts to reproduce the prognostic classification immunohistochemically have, however, provided inconsistent results. The aim(More)
Heat shock gene expression is differentially regulated in cells exposed to stress stimuli and in cells undergoing processes of differentiation and development. Regulation of the classical heat shock response is mediated by heat shock factor 1 (HSF1), whereas heat shock factor 2 (HSF2) is activated in certain differentiating cells, for example during(More)
PURPOSE The aim of this study was to determine whether serum matrix metalloproteinase (MMP) -2 and MMP-9 levels could predict overall and disease-free survival in primary node-positive breast cancer. EXPERIMENTAL DESIGN MMP-2 and MMP-9 levels were quantitatively measured in serum after surgery from 133 patients with primary node-positive breast cancer(More)
