The incidence of breast cancer has doubled over the past 20 years in the Czech Republic. Hereditary factors may be a cause of young onset, bilateral breast or ovarian cancer, and familial accumulation of the disease. BRCA1 and BRCA2 mutations account for an important fraction of hereditary breast and ovarian cancer cases. One thousand and ten unrelated(More)
Alterations in the highly penetrant cancer susceptibility gene BRCA1 are responsible for the majority of hereditary breast and/or ovarian cancers. However, the number of detected germline mutations has been lower than expected based upon genetic linkage data. Undetected deleterious mutations in the BRCA1 gene in some high-risk families could be due to the(More)
Germline mutations in BRCA1 and BRCA2 account for majority of hereditary breast and ovarian cancer. The complete coding sequence analysis of both genes was carried out in 197 breast/ovarian cancer patients from high-risk families and 53 patients with sporadic breast/ovarian cancer. In summary, 59 mutations (16 different) in BRCA1 and 29 mutations (17(More)
BACKGROUND In vitro the Epstein-Barr virus (EBV) encoded latent membrane protein 1 (LMP-1) has been shown to upregulate expression of matrix metalloproteinase 9 (MMP-9), a member of a family of zinc dependent endopeptidases that is believed to facilitate tumour invasion and metastasis by degradation of the extracellular matrix. AIM To test whether the(More)
A single kidney in patients with agenesis or after nephrectomy is regarded as a risk factor. Primarily, the role of glomerular hyperfiltration and later possible glomerular sclerosis are emphasised. Complex treatment of Wilms tumour patients includes previous chemotherapy and radiotherapy. The aim of our study was to investigate late sequelae of this(More)
The majority of hereditary breast and ovarian cancers can be accounted for by germline mutations in the BRCA1 and BRCA2 genes. Genetic counselling and testing in high-risk patients in the Czech Republic began in 1997 in two centres (Masaryk Memorial Cancer Institute in Brno, MMCI, and the General University Hospital plus the First Faculty of Medicine,(More)
The expression of several genes involved in apoptosis and cell cycle control can be regulated by steroid hormones and related agents via their nuclear receptors. Members of the bcl-2 gene family participate in the regulation of apoptosis in a diverse range of cell types and are implicated in the development of hormone refractory prostate cancer and(More)
AIMS Because of the high prevalence of prostatic cancer and the limitations of its treatment, enormous effort has been put into the development of new therapeutic modalities. One potential tool is the use of cyclin dependent kinase (CDK) inhibitors, which are based on the trisubstituted derivatives of purine. The aim of this study was to analyse alterations(More)
