Article
Improved outcome of high-risk early HER2 positive breast cancer with high CXCL13-CXCR5 messenger RNA expression
(2012)Background: Chemokines are important in cell migration and are thought to play a key role in metastasis. We explored the prognostic significance of C-X-C ligand-motif (CXCL) 12, CXCL13, and receptor (CXCR) 5 on disease-free ...

Article
Insights into the epithelial mesenchymal transition phenotype in cancer of unknown primary from a global microRNA profiling study
(2014)Purpose: We sought to study the microRNA regulation of epithelial mesenchymal transition (EMT), the acquisition of migratory, mesenchymal-like properties of epithelial cells, in cancer of unknown primary (CUP). Patients ...

Article
Intracellular signalling via the AKT axis and downstream effectors is active and prognostically significant in cancer of unknown primary (CUP): A study of 100 CUP cases
(2012)Background: Hypothesising that cancer of unknown primary (CUP) may harbour unique characteristics, we present a translational study of the immunohistochemical expression and clinical correlation of key PTEN/AKT pathway ...

Article
Intratumoral CRH modulates immuno-escape of ovarian cancer cells through FasL regulation
(2007)Although corticotropin-releasing hormone (CRH) and Fas ligand (FasL) have been documented in ovarian carcinoma, a clear association with tumour progression and immuno-escape has not been established. FasL plays an important ...

Article
Low expression of p27 protein combined with altered p53 and Rb/p16 expression status is associated with increased expression of cyclin A and cyclin B1 in diffuse large B-cell lymphomas
(2001)The expression of the cyclin-dependent kinase inhibitor (CDKI) p27 protein was investigated in relation to (1) the expression of the cell cycle regulators p53, Rb and p16 and (2) the proliferation profile as determined by ...

Article
Near-absolute expression of the bcl-2 protein identifies a subgroup of stage II breast cancer patients with a most favorable outcome. Results of a clinicopathological study
(2001)The clinical relevance of quantitative assessment of tumor-tissue expression of the bcl-2 protein in operated stage II breast cancer was investigated in this study. Thirty-five cases were studied by immunohistochemistry ...
