PURPOSE We aimed to determine the clinical role of the p53 family members p53 and p73 in the responsiveness to platinum-based chemotherapy and survival in ovarian cancer, considering their cross-talk and the p53 polymorphism at codon 72. EXPERIMENTAL DESIGN A detailed analysis of p53 and p73 in a series of 122 ovarian cancers was done. We used a(More)
OBJECTIVE The tumor suppressor p53 generates the N-terminally truncated isoforms Δ40p53 and Δ133p53 that possess the ability to modulate p53 function in vitro. The aim of the present study was to evaluate the clinical relevance of p53 isoforms in the main histological subtypes of ovarian cancer. METHODS Δ40p53, Δ133p53, and full-length p53 (FLp53)(More)
Cyclin E, coded by the genes CCNE1 and CCNE2, is the main regulator for transition from G1 to S phase determining cell division. CCNE1 and CCNE2 are known oncogenes in many cancer entities. Especially CCNE1 has frequently been associated with gene amplifications in various malignancies, emphasising its role as a putative oncogene. We determined gene(More)
The p73 gene gives rise to the full-length transactivation competent TAp73 and the N-terminally truncated isoform ΔNp73, which inhibits TAp73 and wild-type p53. The clinical relevance of TAp73 and ΔNp73 protein expression has not yet been evaluated in ovarian cancer. TAp73 and ΔNp73 expression was examined using immunohistochemistry and reverse(More)
Tumor-infiltrating immune cells and their prognostic value have been analyzed in various malignancies. Although tissue microarray (TMA) has been used in some of these studies, it is still questionable whether this technique can represent the results of infiltrating CD8+ cells obtained from whole-tissue sections (WTS). The aim of this study was to assess and(More)
A single nucleotide polymorphism (SNP309) of MDM2 causes elevated MDM2 levels and an attenuation of p53 function. The aim of the present study was to examine the clinical relevance of the MDM2 SNP309 in ovarian cancer.MDM2 SNP309 genotype was analyzed in 198 patients with primary ovarian cancer. MDM2 expression was(More)
