Abstract
Type 1 interferons (IFN1) are both key molecules of antiviral defense and potent inflammatory mediators. In 2003, increased expression of a variety of interferon 1-regulated genes was observed in a blood cells of patients with systemic lupus erythematosus (SLE). This phenomenon was called the type 1 interferon signature (IFN1-signature). Since then, expression patterns indicating the presence of an IFN1-signature were consistently detected in a range of monogenic and complex autoimmune and autoinflammatory conditions. A quantitative indicator reflecting the degree of hyperactivation of the IFN1 pathway is known as interferon score. This review discusses the possible causes of upregulated expression of interferon 1-induced genes, the laboratory approaches to the interferon score analysis, as well as the practical use of this indicator for the diagnosis of various conditions.

Abstract
It is well known that cyclooxygenase-2 (COX2) plays an important role in the development of many tumors including breast cancer. Our study was concerned with evaluating the effects of the selective COX2 inhibitor, celecoxib, on mammary tumorigenesis and aging in HER2/neu transgenic mice (24). Celecoxib (celebrex) 25 mg/kg was administered 5 times a week from the age of 2 months. Twenty-four intact females were in control. Monitoring kept track of tumor detection time, size, presence of lung metastases, food and water consumption, estral function, body weight and temperature. No significant differences between the two groups were reported as far as life-span, tumor growth rate, size and number of metastases to the lung is concerned. To sum up, celecoxib treatment failed to produce any significant effect on carcinogenesis in HER2/neu transgenic mice.

Abstract
The CYP19 gene encodes the enzyme aromatase, which plays a key role in the conversion of androgens to oestrogens. A polymorphism in CYP19 in intron 4 (TTTA)n has been reported to be associated with breast cancer (BC) risk, although conflicting evidence has also been published. Here, we employ a non-traditional, highly demonstrative design of a molecular epidemiological study, where the comparison of BC cases and healthy middle-aged female donors was supplemented by an analysis of groups with extreme characteristics of either BC risk (bilateral breast cancer (biBC) patients) or cancer tolerance (tumour-free elderly women aged >or=75 years). None of the (TTTA)n polymorphic variants was significantly overrepresented among the affected women compared with any of the control groups. However, a 3-bp deletion/insertion CYP19 polymorphism, which is located in the same intron approximately 50 bp upstream to the (TTTA)n repeat, was evidently associated with the menopausal status in both the BC and biBC cohorts. In particular, the Delta3(TTTA)(7) allele occurred significantly more frequently in premenopausal than in postmenopausal BC patients (65/172 (38%) versus 67/310 (22%); P=0.0001; Odds Ratio (OR)=2.20 (95% Confidence Interval (CI) 1.46-3.32)), while the perimenopausal cases demonstrated an intermediate value (9/34 (26%)). In the biBC cohort, women who developed both tumours during their premenopausal period had a significantly higher prevalence of the Delta3(TTTA)(7) allele than patients with a postmenopausal onset of bilateral disease (16/46 (35%) versus 8/50 (16%); P=0.035; OR=2.80 (1.08-7.23)); those biBC patients, whose tumours were diagnosed before and after the cessation of menses, displayed an intermediate occurrence of the Delta3(TTTA)(7) allele (7/32 (22%)). Similar tendencies in the Delta3(TTTA)(7) allele distribution in BC and biBC patients suggest that its association with the menopausal status of the patients is truly non-random and thus this observation deserves further detailed investigation.

Abstract
Tissue transglutaminase (tTG) is known to participate in multiple cellular processes, including apoptosis, cellular adhesiveness etc. Alterations of tTG expression could contribute to the development of several categories of diseases, including AIDS, cancer etc. The aim of the study was to test the pattern and relevance of tTG expression in a subset of breast carcinomas. RT-PCR has detected tTG-specific RNA message in 11 out of 25 (44%) breast cancer samples. tTG message was detected in 6/8 (75%) breast carcinomas with high apoptotic index, but only in 5/17 (29%) with the low one (p = 0.03). Immunohistochemical analysis revealed that only 15% of breast carcinomas displayed tTG protein in tumor cells, while the staining of the stromal components occurred in approximately one-half of the tumours tested. Surprisingly, there was no significant association between tTG RNA expression and protein positivity. Moreover, there was no evident relationships between tTG immunostaining and apoptotic index or clinical parameters of breast neoplasms. There are at least 2 alternative explanations for the poor concordance between RNA and protein data. It is likely that the sensitivity of immunohistochemistry is not sufficient to detect functionally relevant tTG enzyme in all breast cancer sections. Otherwise, tTG RNA expression does not always lead to accumulation of its product in the tumor cells, but reflects the transcriptional activation of other pro-apoptotic genes due to common triggering mechanisms.

Abstract
PURPOSE Initiation/promotion of endometrial cancer is known to be associated with estrogenic influence. Therefore, it is possible that some allelic polymorphisms of the genes involved in steroidogenesis or steroid metabolism contribute to endometrial cancer susceptibility. METHODS Here, we compared CYP19 (aromatase) gene polymorphism in 85 endometrial cancer patients and in 110 non-affected women. RESULTS The genotypes containing the longest alleles (A6 and A7) of CYP19 were found to be over-represented in patients as compared to controls. In addition, these genotypes demonstrated a tendency to be associated with increased concentrations of estradiol and testosterone in postmenopausal patients. CONCLUSIONS Thus, CYP19 polymorphism might be one of the genetic risk factors for endometrial cancer development.

Abstract
The CYP17 gene encodes an enzyme involved in several critical steps of steroidogenesis. The promoter region of the CYP17 displays a single-nucleotide polymorphism, which is suspected to modulate the expression of the gene and thus may contribute in the interindividual variations of hormonal background. In agreement with this functional hypothesis, the MspA1+ allele (designated as A2) of the CYP17 was shown to render an increased risk of breast cancer (BC). However, the latter observation was disputed by a series of negative reports. Here, we re-evaluated the role of CYP17 MspA1 polymorphism in the BC susceptibility, using a non-traditional design of a case-control study. In addition to randomly selected 183 BC patients and 107 female middle-aged donors, we examined the groups with apparently extreme characteristics of either BC risk or BC resistance, namely the 57 bilateral breast cancer (biBC) patients and 75 elderly (>/=75 years old) tumor-free women. Neither BC nor biBC patients showed increased prevalence of 'unfavorable' A2 allele as compared with the non-affected cohorts. Moreover, the A2 variant was not significantly associated with the tumor size, nodal involvement and menopausal status in the patients either with the monolateral or bilateral disease. Thus, our data argue against the earlier reported role of the CYP17 in BC predisposition and progression. In addition, usual distribution of the CYP17 alleles in the elderly group indicates a neutral effect of this polymorphism on the longevity in females.

Abstract
The molecular pathogenesis of various categories of breast cancer (BC) has been well described, but surprisingly few reports have appeared on analysis of somatic mutations in bilateral BC. We have performed a polymerase chain reaction (PCR)-driven investigation of chromosomal regions showing common loss of heterozygosity (LOH) in 23 cases (46 tumors) from patients diagnosed with bilateral BC. LOH was observed in 15/46 (33%) informative tumors for chromosome 1p, 5/32 (16%) for 5q, 12/44 (27%) for 11q, 15/40 (38%) for 13q and 4/24 (17%) for 17p. These values are within the range of interlaboratory variations reported for unilateral BC. There was no strong evidence for concordance of LOH within the same patient for any of the chromosomal loci tested. Atypical for breast carcinomas, 7/46 (15%) tumors accumulated a high frequency (ranging from 11 to 29%) of shortened dinucleotide CA repeats, implying microsatellite instability (MI). Further analysis with the highly informative BAT-26 marker allowed for the classification of two of these tumors as having a replication error positive (RER(+)/MSI-H) phenotype, whereas the remaining five carcinomas harbored so-called borderline MI. Thus an involvement of both RER(+) and borderline MI appears to be a distinct feature of bilateral breast carcinomas compared to unilateral lesions.

Abstract
L-myc polymorphism was investigated in 95 breast cancer (BC), 63 colorectal cancer (CC) and 58 lung cancer (LC) patients, as well as in 122 healthy, middle-aged blood donors (HBDs) and 184 elderly, tumor-free individuals. The occurrence of the S allele in the BC cohort (57%) was significantly higher than that in middle-aged, healthy females (41%) and elderly, non-affected women (47%), implying involvement of the L-myc genotype in BC susceptibility (age-adjusted OR = 1.74, 95% CI 1.11-2.73, p = 0.016). L-myc allele distribution in CC and LC was similar to that in controls. Contrary to earlier reports, L:S allele frequencies ratio in elderly blood donors (EBDs) did not significantly differ from that in HBDs (0.49:0. 51 and 0.54:0.46, respectively). However, the S allele had a tendency to be over-represented among elderly compared with middle-aged smokers (55% vs. 44%; OR = 1.57, 95% CI 0.98-2.50, p = 0. 059), which implies that it may be linked with tolerance to smoking effects.
