Abstract 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, Charles University in Prague, 1FMUK). Health insurance covers testing in MMCI, whereas testing at 1FMUK is covered by research grants. The spectrum of mutations in the BRCA1 gene is similar in the Bohemian (western) and Moravian (eastern) regions of the country but the mutation spectrum observed in the BRCA2 gene is completely different. There are three BRCA1 gene mutations that are responsible for 69% and 70.4% of all BRCA1 mutations identified in women reporting to the Brno and Prague centres, respectively. The two most frequent mutations in the BRCA2 gene, which comprises 41.5% of all detected BRCA2 mutations in Brno, were not found in women tested in the Prague centre. The testing of BRCA1/BRCA2 or other possible predisposition genes for hereditary breast/ovarian cancer is determined by medical geneticists after genetic counselling. Predictive testing is offered to persons older than 18 years of age. Genetic counselling centres are easily accessible to all inhabitants in the country. Specialized preventive care is mostly organized by MMCI and the General University Hospital in Prague; however, some patients and their family members are under the care of other oncology departments and clinics. The quality of preventive care in different hospitals is currently being investigated.

This article is open access. Individuals carrying pathogenic mutations in the BRCA1 and BRCA2 genes have a high lifetime risk of breast cancer. BRCA1 and BRCA2 are involved in DNA double-strand break repair, DNA alterations that can be caused by exposure to reactive oxygen species, a main source of which are mitochondria. Mitochondrial genome variations affect electron transport chain efficiency and reactive oxygen species production. Individuals with different mitochondrial haplogroups differ in their metabolism and sensitivity to oxidative stress. Variability in mitochondrial genetic background can alter reactive oxygen species production, leading to cancer risk. In the present study, we tested the hypothesis that mitochondrial haplogroups modify breast cancer risk in BRCA1/2 mutation carriers. We genotyped 22,214 (11,421 affected, 10,793 unaffected) mutation carriers belonging to the Consortium of Investigators of Modifiers of BRCA1/2 for 129 mitochondrial polymorphisms using the iCOGS array. Haplogroup inference and association detection were performed using a phylogenetic approach. ALTree was applied to explore the reference mitochondrial evolutionary tree and detect subclades enriched in affected or unaffected individuals. We discovered that subclade T1a1 was depleted in affected BRCA2 mutation carriers compared with the rest of clade T (hazard ratio (HR) = 0.55; 95% confidence interval (CI), 0.34 to 0.88; P = 0.01). Compared with the most frequent haplogroup in the general population (that is, H and T clades), the T1a1 haplogroup has a HR of 0.62 (95% CI, 0.40 to 0.95; P = 0.03). We also identified three potential susceptibility loci, including G13708A/rs28359178, which has demonstrated an inverse association with familial breast cancer risk. This study illustrates how original approaches such as the phylogeny-based method we used can empower classical molecular epidemiological studies aimed at identifying association or risk modification effects.

International audience; Large genomic rearrangements (LGR) represent substantial proportion of pathogenic mutations in the gene, whereas the frequency of rearrangements in the gene is low in many populations. We screened for LGRs in and genes by multiplex ligation-dependent probe amplification (MLPA) in 521 unrelated patients negative for point mutations selected from 655 Czech high-risk breast and/or ovarian cancer patients. Besides long range PCR, a chromosome 17-specific oligonucleotide-based array comparative genomic hybridization (aCGH) was used for accurate location of deletions. We identified 14 patients carrying 8 different LGRs in that accounted for 12.3% of all pathogenic mutations. No LGRs were detected in the gene In a subgroup of 239 patients from high-risk families, we found 12 LGRs (5.0%), whereas two LGRs were revealed in a subgroup of 282 non-familial cancer cases (0.7%). Five LGRs (deletion of exons 1–17, 5–10, 13–19, 18–22 and 21–24) were novel; two LGRs (deletion of exons 5–14 and 21–22) belong to the already described Czech-specific mutations; one LGR (deletion of exons 1–2) was reported from several countries. The deletions of exons 1–17 and 5–14, identified each in four families, represented Czech founder mutations. The present study indicates that screening for LGRs in should include patients from breast or ovarian cancer families as well as high-risk patients with non-familial cancer, in particular cases with early-onset breast or ovarian cancer. On the contrary, our analyses do not support the need to screen for LGRs in the gene Implementation of chromosome-specific aCGH could markedly facilitate the design of primers for amplification and sequence analysis of junction fragments, especially in deletions overlapping gene boundaries.

- Abstract
Germline mutations in the BRCA1and BRCA2genes have been shown to account for the majority of hereditary breast and ovarian cancers. The purpose of our study was to estimate the incidence and spectrum of pathogenic mutations in BRCA1/2genes in high-risk Czech families. A total of 96 Czech families with recurrent breast and/or ovarian cancer and 55 patients considered to be at high-risk but with no reported family history of cancer were screened for mutations in the BRCA1/2genes. The entire coding sequence of each gene was analyzed using a combination of the protein truncation test and direct DNA sequencing. A total of 35 mutations in the BRCA1/2genes were identified in high-risk families (36.5%). Pathogenic mutations were found in 23.3% of breast cancer families and in 59.4% of families with the occurrence of both breast and ovarian cancer. In addition, four mutations were detected in 31 (12.9%) women with early onset breast cancer. One mutation was detected in seven (14.3%) patients affected with both a primary breast and ovarian cancer and another in three (33.3%) patients with a bilateral breast cancer. A total of 3 mutations in BRCA1were identified among 14 (21.4%) women with a medullary breast carcinoma. Of 151 analyzed individuals, 35 (23.2%) carried a BRCA1mutation and 9 (6.0%) a BRCA2mutation. One novel truncating mutation was found in BRCA1(c.1747A>T) and two in BRCA2(c.3939delC and c.5763dupT). The 35 identified BRCA1mutations comprised 13 different alterations. Three recurrent mutations accounted for 71.4% of unrelated individuals with detected gene alterations. The BRCA1c.5266dupC (5382insC) was detected in 51.4% of mutation positive women. The mutations c.3700_3704del5 and c.181T>G (300T>G) contributed to 11.4% and 8.6% of pathogenic mutations, respectively. A total of eight different mutations were identified in BRCA2. The novel c.5763dupT mutation, which appeared in two unrelated families, was the only recurrent alteration of the BRCA2gene identified in this study. Mutational analysis of BRCA1/2genes in 151 high-risk patients characterized the spectrum of gene alterations and demonstrated the dominant role of the BRCA1c.5266dupC allele in hereditary breast and ovarian cancer.

- Abstract
Attractin/mahogany protein was previously shown to be involved in a number of physiological and pathological events, including immune system regulation, body weight control, pigmentation, myelinization, and tumor susceptibility. Human attractin has an enzymatic activity resembling dipeptidyl peptidase IV (DPP-IV). In the central nervous system, attractin has been detected in neurons but not in glial cells up to now. We show the expression of attractin mRNA and protein in glioma cell lines at different degree of transformation. In human U373 and U87 glioma cells (Grades III and IV), membrane-bound attractin displays hydrolytic activity amounting to 5 and 25% of total cellular DPP-IV-like enzyme activity, respectively. Such activity has not been observed in the rat C6 glioma cells (Grade I). Attractin presence in glioma, but not in normal glial cells, together with its differential enzymatic activity, suggests its role in growth properties of tumors of glial cell origin.

- Abstract
1. A protein factor promoting the binding of initiator tRNA to the 40S ribosomal subunit was purified to homogeneity (more than 2500-fold) from rat liver cytosol. It has a mol.wt. of 265000 and is composed of four subunits of identical molecular weight. 2. This factor directs the binding of methionyl-tRNAfMet and to a lesser extent also of N-acetylphenylalanyl-tRNA, but not of methionyl-tRNAMet or phenylalanyl-tRNA, to the smaller ribosomal subunit at high concentrations of GTP (8–10mm) with an optimum at pH4.0. As evidenced by sucrose-density-gradient centrifugation, initiator tRNA becomes bound to the 40S subunit or to 80S ribosomes. 3. A deacylase activity specific for methionyl-tRNAfMet is associated with the pure factor. The factor significantly stimulates the translation of natural message in systems containing polyribosomes and both purified peptide-elongation factors. 4. The factor binds initiator tRNA or GTP to form unstable binary complexes and forms a ternary complex with methionyl-tRNAfMet and GTP. This complex is relatively stable. 5. In the absence of any cofactors the factor forms a stable complex with 40S and 80S ribosomes. This preformed ribosomal complex binds efficiently initiator tRNA at pH7.5 and low concentrations of GTP (1–2mm). The ternary complex of the factor with methionyl-tRNAfMet and GTP may be liberated from this ribosomal complex. 6. A protein factor capable of promoting the binding and simultaneously the deacylation of initiator tRNA may apparently have a regulatory function in physiological gene translation by removing an excess of methionyl-tRNAfMet not required for translation.

We did not find mutation in coding areas of genes for components of TGFbeta1 signaling pathway but we detected decreased or undetectable expression of these analysed genes.The decreased expression is probably caused by epigenetic changes, so by hypermethylation and deacetylation of promoter regionsof these genes.Antiproliferative and apoptotic effect of TGF1 was analysed in AML cell lines (ML1, ML2, CTV1 and Kasumi1). ML2 cells rezistence to inhibition of DNA synthesis by TGFβ1 is not caused by mutations of genes for components of TGFβ1 signaling pathway. We found that increased SnoN (Ski-like novel gene) expression on the level of coresponding mRNA and protein is probably accountable for this rezistence. Kasumi1 and M2 cells were sensitive to induction of apoptózis caused by TGFβ1 treatment but in less extent than by proteazome inhibitor bortezomib. The difference of AML cells of different lines answers shows a great heterogeneity AML in AML patients. Prognostic factors analysis in AML with normal karyotype confirmed that CEBPA (CCAAT/enhancer binding protein alpha) mutations predict favourable prognosis but the elevated EVI1 ("Ecotropic Virus Integration Site 1") and ERG ("ETS-related gene") expression are connected with unfavourable prognosis. EVI1 is a negative marker for MDS as well. We did not confirm...

Background: A greatly increased risk for development of hereditary breast cancer is associated with germline mutations in several susceptibility genes. In this study we analyzed large genomic rearrangements (LGRs) in BRCA1/2 genes and we also focused on the role of CHEK2 and TP53 in tumorigenesis. Methods: A series of 586 high risk patients with breast/ovarian cancer that had previously been tested negatively for small mutations in BRCA1/2 was screened for LGRs by MLPA, LR-PCR and sequencing. Chromosome 17-specific aCGH was used to locate deletion breakpoints in regions flanking the BRCA1 gene. MLPA-analysis was also used to detect two frequently occurring mutations in CHEK2 (c.1100delC and a deletion of 5395 bp). The coding region of the TP53 gene was analyzed by sequencing. Results: We identified 9 different LGRs in the BRCA1 gene in 16 patients. Five alterations (deletion of exons 1-17, 5-10, 13-19, 18-22 and 21-24) were novel. Deletions of exons 1-17, 5-14 and 21-22 were identified repeatedly, and represented population specific (founder) mutations. LGRs accounted for 12.1% (16/132) of all detected pathogenic BRCA1 mutations. No LGRs were found in the BRCA2 gene. Pathogenic mutations in other tested genes were less frequent; 2 were detected in TP53 and 9 in CHEK2. Conclusions: In our population, LGRs...

skin and connective tissue diseases - Abstract
Incidence of breast cancer is continuously increasing in the Czech Republic. Tumor development is a result of gene alterations'accumulation, particulary associated with genes involved in regulation of cell growth and division. Hereditary carcinomas account for approximately 5-10% of all breast tumors and in 60-80% cases are caused by a germline mutation in the major predisposition genes BRCA1 and BRCA2. Nevertheless, other genes, mostly of lower penetrance, may play a role in breast pathogenesis such as the ATM tumor-suppressor gene. ATM is the apex of the repair pathway of DSB. This protein kinase activates through phosphorylation of its substrates cell cycle checkpoints, which leads either to the delay of the cell cycle progression until DSB are repaired or to the promotion of apoptosis. To sum up, the ATM gene seems to have a role in breast cancer development in a minority of the high-risk families in our population which is significantly lower compared to BRCA1/2 and it also seems to be involved in pathogenesis of sporadic breast cancer. Despite the ATM gene's length, we do not perform the preventive screening of this gene in breast cancer high-risk families. Nevertheless, we offer the molecular diagnostics of ATM to ataxia telangiectasia patients.

- Abstract
Mutations in the ATM gene are the cause of a rare autosomal recessive syndrome, ataxia-telangiectasia (AT). Of the general population, approximately 0.35-1% has been estimated to be heterozygous for a germline mutation in the ATM gene. The finding that ATM heterozygotes have an increased breast cancer risk was supported by some studies but not confirmed by others. In our study, the entire coding sequence of the ATM gene was prescreened for mutations by the protein truncation test to detect the chain-terminating mutations that are highly predominant in patients with AT. DNA sequencing then characterized 3 (1.9%) pathogenic mutations among 161 high-risk breast cancer patients. The c.5177+1G>A splicing mutation was a novel gene alteration. No mutation was detected in a group of 183 control individuals. Our results suggest that truncating mutations in ATM increase breast cancer risk and contribute to inherited breast cancer. The analysis further uncovered the c.1066-6T>G splicing mutation once among high-risk patients (0.6%) and twice among controls (1.1%) suggesting that this mutation does not confer an increase in breast cancer risk. On the other hand, individuals heterozygous for this truncating variant displayed loss of exon 11 in approximately 50% of ATM transcripts. Immunohistochemistry did not detect the ATM protein in the tumor sample carrying this mutation. Thus, the association of the c.1066-6T>G mutation with familial breast cancer remains uncertain. Loss of the wild-type ATM allele has not been detected in the tumor samples from heterozygous carriers of the ATM mutation. Our experiments did not detect the hypermethylation of the ATM promoter in any of the DNA samples from tumor tissues.
