We have generated DNA methylation profiles of 148 human breast tumors and found significant differences in hormone receptor (HR) status between clusters of DNA methylation profiles. Of 35 DNA methylation markers analyzed, the ESR1 gene, encoding estrogen receptor ␣, proved to be the best predictor of progesterone receptor status, whereas methy-lation of the(More)
This study analysed mRNA expression of two members of the methyl-CpG-binding protein family - MeCP2 and MBD2 - in human non-neoplastic (n=11) and neoplastic (n=57) breast tissue specimens using a quantitative real-time PCR method. We observed higher expression levels of MeCP2 mRNA in neoplastic tissues than in non-neoplastic tissues (P=0.001), whereas no(More)
L1CAM promotes cell motility, invasion and metastasis formation in various human cancers and can be considered as a driver of tumor progression. Knowledge about genetic processes leading to the presence of L1CAM in cancers is of considerable importance. Experimentally, L1CAM expression can be achieved by various means. Over-expression of the transcription(More)
Intraperitoneal treatment with interferon-gamma (IFN-gamma) has been shown to achieve surgically documented responses in the second-line therapy of ovarian cancer. To assess its efficacy in the first-line therapy, we conducted a randomized controlled trial with 148 patients who had undergone primary surgery for FIGO stage Ic-Illc ovarian cancer. In the(More)
BACKGROUND Suppressor of cytokine signaling (SOCS) proteins comprise a protein family, which has initially been described as STAT induced inhibitors of the Jak/Stat pathway. Recent in vivo and in vitro studies suggest that SOCS proteins are also implicated in cancer. The STAT5 induced IGF-I acts as an endocrine and para/autocrine growth and differentiation(More)
BACKGROUND The role of CHAC1 (cation transport regulator-like protein 1), a recently identified component of the unfolded protein response (UPR) pathway, in gynaecological cancers has not yet been characterised. Now, this work illustrates CHAC1 mRNA expression and associated clinical outcome in breast and ovarian cancer. METHODS The prognostic value of(More)
Ovarian cancer remains still associated with poor prognosis because it is diagnosed predominantly at advanced stages. Ovarian-specific tumor markers do not yet exist for early detection of the disease. At the search of diagnostic markers for ovarian cancer, proteomic-based approaches have focused on novel investigations of neoplastic processes in tumor(More)
E7 is the major oncoprotein of high-risk human papillomaviruses (HPV) which causes cervical cancer. To date E7 oncoproteins have not been investigated in cervical adenocarcinoma. In this study we generated a rabbit monoclonal anti-HPV-16 E7 antibody, RabMab42-3, which recognizes a conformational epitope in the E7 carboxy-terminal zinc-finger resulting in a(More)
L1CAM was originally identified as an adhesion molecule involved in neural development. In many human carcinomas L1CAM is over-expressed and is associated with a bad prognosis. We previously reported that L1CAM was absent in the vast majority of endometrioid endometrial carcinomas (ECs) (type 1) but was strongly expressed in the more aggressive serous and(More)
We investigated delayed-type hypersensitivity to human papillomavirus (HPV) in women with cervical dysplasia or cancer. Women were challenged by skin tests with synthetic HPV-16 E7 oncoprotein peptides. 11 women were regressors (cleared disease without treatment) and 37 were progressors (required surgery). Antibodies to early antigens (markers for(More)
