Abstract
High-risk Human Papillomavirus (HR-HPV) genotypes, specifically HPV16 and HPV18, pose a significant risk for the development of cervical intraepithelial neoplasia and cervical cancer. In the multifaceted cervical microenvironment, consisting of immune cells and diverse microbiota, Lactobacillus emerges as a pivotal factor, wielding significant influence in both stabilizing and disrupting the microbiome of the reproductive tract. To analyze the distinction between the cervical microbiota and Lactobacillus-dominant/non-dominant status of HR-HPV and non-infected healthy women, sixty-nine cervical swab samples were analyzed, included 44 with HR-HPV infection and healthy controls. All samples were recruited from Human Papillomavirus-based cervical cancer screening program and subjected to 16s rRNA sequencing analysis. Alpha and beta diversity analyses reveal no significant differences in the cervical microbiota of HR-HPV-infected women, including 16 and 18 HPV genotypes, and those with squamous intraepithelial lesion (SIL), compared to a control group. In this study we identified significantly lower abundance of Lactobacillus mucosae in women with HR-HPV infection compared to the control group. Furthermore, changes in bacterial diversity were noted in Lactobacillus non-dominant (LND) samples compared to Lactobacillus-dominant (LD) in both HR-HPV-infected and control groups. LND samples in HR-HPV-infected women exhibited a cervical dysbiotic state, characterized by Lactobacillus deficiency. In turn, the LD HR-HPV group showed an overrepresentation of Lactobacillus helveticus. In summary, our study highlighted the distinctive roles of L. mucosae and L. helveticus in HR-HPV infections, signaling a need for further research to demonstrate potential clinical implications of cervical microbiota dysbiosis.

Abstract
Monocyte chemoattractant protein-induced protein 1 (MCPIP1), also called Regnase-1, is an RNase that has been described as a key negative modulator of inflammation. MCPIP1 also controls numerous tumor-related processes, such as proliferation, apoptosis and differentiation. In this study, we utilized a zebrafish model to investigate the role of Mcpip1 during embryogenic development. Our results demonstrated that during embryogenesis, the expression of the zc3h12a gene encoding Mcpip1 undergoes dynamic changes. Its transcript levels gradually increase from the 2-cell stage to the spherical stage and then decrease rapidly. We further found that ectopic overexpression of wild-type Mcpip1 but not the catalytically inactive mutant form resulted in an embryonic lethal phenotype in zebrafish embryos (24 hpf). At the molecular level, transcriptomic profiling revealed extensive changes in the expression of genes encoding proteins important in the endoplasmic reticulum stress response and in protein folding as well as involved in the formation of primary germ layer, mesendoderm and endoderm development, heart morphogenesis and cell migration. Altogether, our results demonstrate that the expression of zc3h12a must be tightly controlled during the first cell divisions of zebrafish embryos and that a rapid decrease in its mRNA expression is an important factor promoting proper embryo development.

Abstract
For a long time, the uterus had been considered a sterile organ, meaning that under physiological conditions the uterus would not be colonized by bacteria. Based on available data, it may be concluded that the gut and uterine microbiome are related, and that the role of this microbiome is greater than expected. Despite being the most common pelvic neoplasms in women of reproductive age, uterine fibroids (UFs) are still poorly understood tumors whose etiology has not been fully determined. This systematic review presents the relationship between intestinal and uterine dysbiosis and uterine fibroids. A systematic review of three medical databases was carried out: the MEDLINE/PubMed, Scopus and Cochrane. In this study, 195 titles and abstracts were reviewed, including only original articles and clinical trials of uterine microbiome criteria. Finally, 16 studies were included to the analysis. In recent years, researchers dealing with reproduction in a broad sense have focused on the microbiome in various locations to study its role in the pathogenesis and, consequently, the prevention and treatment of diseases of the genital organ. Conventional microbial detection methods are not suitable for identifying bacteria, which are difficult to culture. Next-generation sequencing (NGS) provides an easier and faster and more informative analysis of bacterial populations. It seems that gut microbiota dysbiosis has the potential to be a risk factor for uterine fibroids or affect the disease process. Some changes were shown in many types of bacteria, such as Firmicutes, Proteobacteria, Actinobacteria and Verrucomicrobia detected in fecal samples in patients with uterine fibroids. In view of the few results on the link between the microbiome and uterine fibroids, further intensive studies in humans and animal models are necessary, including the possible use of different microbiome modulations in the prevention or treatment of uterine fibroids.

Abstract
Spent mushroom compost (SMC) is a lignocellulose-rich waste material commonly used in the passive treatment of heavy metal-contaminated environments. In this study, we investigated the bioremediation potential of SMC against an inorganic form of arsenic, examining the individual abiotic and biotic transformations carried out by SMC. We demonstrated, that key SMC physiological groups of bacteria (denitrifying, cellulolytic, sulfate-reducing, and heterotrophic) are resistant to arsenites and arsenates, while the microbial community in SMC is also able to oxidize As(III) and reduce As(V) in respiratory metabolisms, although the SMC did not contain any As. We showed, that cooperation between arsenate and sulfate-reducing bacteria led to the precipitation of AsxSy. We also found evidence of the significant role organic acids may play in arsenic complexation, and we demonstrated the occurrence of As-binding proteins in the SMC. Furthermore, we confirmed, that biofilm produced by the microbial community in SMC was able to trap As(V) ions. We postulated, that the above-mentioned transformations are responsible for the sorption efficiency of As(V) (up to 25%) and As(III) (up to 16%), as well as the excellent buffering properties of SMC observed in the sorption experiments.

Abstract
BACKGROUND Pancreatic cyst fluids (PCFs) enriched in tumor-derived DNA are a potential source of new biomarkers. The study aimed to analyze germinal variants and mutational profiles of cell-free (cf)DNA shed into the cavity of pancreatic cysts. METHODS The study cohort consisted of 71 patients who underwent endoscopic ultrasound fine-needle aspiration of PCF. Five malignant cysts, 19 intraductal papillary mucinous neoplasms (IPMNs), 11 mucinous cystic neoplasms (MCNs), eight serous cystic neoplasms (SCNs), and 28 pseudocysts were identified. The sequencing of 409 genes included in Comprehensive Cancer Panel was performed using Ion Proton System. The mutation rate of the KRAS and GNAS canonical loci was additionally determined using digital PCR. RESULTS The number of mutations detected with NGS varied from 0 to 22 per gene, and genes with the most mutations were: TP53, KRAS, PIK3CA, GNAS, ADGRA2, and APC. The frequencies of the majority of mutations did not differ between non-malignant cystic neoplasms and pseudocysts. NGS detected KRAS mutations in malignant cysts (60%), IPMNs (32%), MCNs (64%), SCNs (13%), and pseudocysts (14%), with GNAS mutations in 20%, 26%, 27%, 13%, and 21% of samples, respectively. Digital PCR-based testing increased KRAS (68%) and GNAS (52%) mutations detection level in IPMNs, but not other cyst types. CONCLUSIONS We demonstrate relatively high rates of somatic mutations of cancer-related genes, including KRAS and GNAS, in cfDNA isolated from PCFs irrespectively of the pancreatic cyst type. Further studies on molecular mechanisms of pancreatic cysts malignant transformation in relation to their mutational profiles are required.

Abstract
The cough reflex is an airway defensive process that can be modulated by afferent inputs from organs located also out of the respiratory system. A bidirectional relationship between cough and heart dysfunctions are presented in the article, with the special insights into an arrhythmia-triggered cough. Albeit rare, cough induced by cardiac pathologies (mainly arrhythmias) seems to be an interesting and underestimated phenomenon. This condition is usually associated with the presence of abnormal heart rhythms and ceases with successful treatment of arrhythmia either by pharmacotherapy or by radiofrequency ablation of arrhythmogenic substrate. The two main hypotheses on cough-heart relationships - reflex and hemodynamic - are discussed in the review, including the authors' perspective based on the experiences with an arrhythmia-triggered cough.

Abstract
Background: Sarcomas are rare malignant tumors of mesenchymal origin. The discovery of circulating biomarkers with high diagnostic value could supplement diagnosis of this heterogenous group of tumors. The aim of this study was to identify the profiles of circulating miRNA (c-miRNAs) in four groups of common bone and soft tissue sarcomas. Methods: At the time of diagnosis, blood samples were collected from 86 patients: 36 with locally advanced/unresectable/metastatic gastrointestinal stromal tumor (GIST) who received first-line treatment with imatinib; 16 with locally advanced osteosarcoma (OS); 26 with locally advanced synovial sarcoma (SS); and eight with locally advanced Ewing sarcoma (ES). In addition, samples were collected from 30 healthy controls. C-miRNAs were isolated using a miRCURY RNA Isolation Kit, followed by preparation of cDNA libraries and sequencing on the Ion Proton platform. Results: Pair-wise comparisons identified 156 unique c-miRNAs (adjusted P-value < 0.05) showing significant dysregulation between controls and patients; of these, 24, 36, 42, and 99 differentiated controls from pretherapeutic OS, SS, ES, and GIST, respectively. Ten c-miRNAs were commonly altered in at least three sarcoma types. Receiver operating characteristic curves and area under the curve (ROC-AUC) analyses revealed that a four-miRNA diagnostic classifier was able to differentiate controls from ES, GIST, OS, and SS, with AUC-ROC values of 1, 0.97, 0.95, and 0.94, respectively. Conclusions: Aberrant miRNA expression signatures were identified in serum from patients with four different sarcoma subtypes. Differences in miRNA expression profiles between sarcoma patients and healthy volunteers suggest that miRNAs may play a role in sarcoma development.

Abstract
BACKGROUND The Human Cell Atlas is a large international collaborative effort to map all cell types of the human body. Single-cell RNA sequencing can generate high-quality data for the delivery of such an atlas. However, delays between fresh sample collection and processing may lead to poor data and difficulties in experimental design. RESULTS This study assesses the effect of cold storage on fresh healthy spleen, esophagus, and lung from ≥ 5 donors over 72 h. We collect 240,000 high-quality single-cell transcriptomes with detailed cell type annotations and whole genome sequences of donors, enabling future eQTL studies. Our data provide a valuable resource for the study of these 3 organs and will allow cross-organ comparison of cell types. We see little effect of cold ischemic time on cell yield, total number of reads per cell, and other quality control metrics in any of the tissues within the first 24 h. However, we observe a decrease in the proportions of lung T cells at 72 h, higher percentage of mitochondrial reads, and increased contamination by background ambient RNA reads in the 72-h samples in the spleen, which is cell type specific. CONCLUSIONS In conclusion, we present robust protocols for tissue preservation for up to 24 h prior to scRNA-seq analysis. This greatly facilitates the logistics of sample collection for Human Cell Atlas or clinical studies since it increases the time frames for sample processing.

Abstract
Abstract
Cyclin-dependent kinase 8 inhibitors (CDK8i) have anti-cancer activity in human acute myeloid leukaemia (AML) cell lines both in vitro and in vivo. Activity of CDK8i often involves deregulation of super-enhancer-associated genes in AML cell lines. Previous studies established SEL120 as a specific CDK8 inhibitor active in AML cells with increased STAT1/5 signalling pathways. Differential gene expression analysis demonstrated high enrichment of leukaemia stem cell (LSC) signatures in responding cells, linked to resistance to standard therapies and relapsed disease. Cells sensitive to SEL120 treatment were positive for CD34 and negative for lineage commitment surface markers. SEL120 markedly reduced STAT5 phosphorylation on serine 726 (STAT5 pS726) in sensitive cell lines. Prolonged SEL120 treatment led to significant downregulation of CD34 and induction of lineage commitment markers. Transcriptomic analysis revealed that SEL120 regulated many genes involved in differentiation and apoptosis. We observed synergistic effects of SEL120 with standard of care cytotoxic drugs such as cytarabine. Treatment of AML cells with cytarabine spared many CD34+ cells, which could be effectively eradicated by subsequent treatment with SEL120. Many cell lines which were resistant to SEL120 treatment could be sensitized by concomitant treatment with BH3 mimetic agent ABT-199. Combination of both compounds resulted in potent induction of apoptosis in AML cells in vitro and in vivo. Treatment of mice bearing subcutaneously implanted human leukaemia cell lines resulted in significant tumour growth inhibition, whereas cotreatment with ABT-199 led to complete regressions at doses which were vey well tolerated by animals. Next we have selected patient derived primary AML cells using gene expression signatures identifying SEL120 -responder cell lines. In these cells SEL120 significantly reduced viability, induced apoptosis and lineage commitment. Further, the same cells were implanted into NOD scid gamma mice. Animals succumbed to AML, diagnosed by a significant presence of human CD45/CD34 positive leukaemia cells in a peripheral blood and splenomegaly. Stand-alone treatment with SEL120 resulted in the complete remission of AML cells in a peripheral blood and bone marrow, and reduced spleen weight, without symptoms of compound-related toxicity. These results validate SEL120 as a promising agent in the treatment of AML.

Abstract
BACKGROUND AND AIMS The study investigates the practical utility of whole-blood gene expression profiling to diagnose inflammatory bowel diseases [IBDs]. METHODS The discovery cohorts included 102 and 51 paediatric IBD patients and controls, and 95 and 46 adult IBD patients and controls, respectively. The replication cohorts included 447 and 76 paediatric IBD patients and controls, and 271 and 108 adult IBD patients and controls, respectively. In the discovery phase, RNA samples extracted from whole peripheral blood were analysed using RNA-Seq, and the predictive values of selected biomarkers were validated using quantitative polymerase chain reaction [qPCR]. RESULTS In all, 15 differentially expressed transcripts [adjusted p ≤0.05] were selected from the discovery sequencing datasets. The receiver operating characteristic curves and area under the curve [ROC-AUC] in replication analyses showed high discriminative power [AUC range, 0.91-0.98] for 11 mRNAs in paediatric patients with active IBD. By contrast, the AUC-ROC values ranged from 0.63 to 0.75 in comparison among inactive paediatric IBDs and active/inactive adult IBDs, indicating a lack of discriminative power. The best multi-mRNA diagnostic classifier showed moderate discriminative power [AUC = 0.81] for paediatric inactive IBD, but was not able to discriminate active or inactive adult IBD patients from controls. The AUC-ROC values did not confirm an ability of the mRNAs abundances to discriminate between active ulcerative colitis and active Crohn's disease in paediatric or adult populations. CONCLUSIONS This study identifies and validates blood transcriptional biomarkers that could be used in clinical settings as diagnostic predictors of IBD clinical activity in paediatric, but not adult, IBD patients.

Abstract
BACKGROUND & AIMS Wilson's disease (WD) is an autosomal recessive disorder associated with disease-causing alterations across the ATP7B gene, with highly variable symptoms and age of onset. We aimed to assess whether the clinical variability of WD relates to modifier genes. METHODS A total of 248 WD patients were included, of whom 148 were diagnosed after age of 17. Human exome libraries were constructed using AmpliSeq technology and sequenced using the IonProton platform. RESULTS ATP7B p.His1069Gln mutation was present in 215 patients, with 112 homozygotes and 103 heterozygotes. Three other mutations: p.Gln1351Ter, p.Trp779Ter and c.3402delC were identified in >10 patients. Among patients, 117 had a homozygous mutation, 101 were compound heterozygotes, 27 had one heterozygous mutation, and 3 other patients had no identifiable pathogenic variant of ATP7B. Sixteen mutations were novel, found as part of a compound mutation or as a sole, homozygous mutation. For disease phenotype prediction, age at diagnosis was a deciding factor, while frameshift allelic variants of ATP7B and being male increased the odds of developing a neurological phenotype. Rare allelic variants in ESD and INO80 increased and decreased chances for the neurological phenotype, respectively, while rare variants in APOE and MBD6 decreased the chances of WD early manifestation. Compound mutations contributed to earlier age of onset. CONCLUSIONS In a Polish population, genetic screening for WD may help genotype for four variants (p.His1069Gln, p.Gln1351Ter, p.Trp779Ter and c.3402delC), with direct sequencing of all ATP7B amplicons as a second diagnostic step. We also identified some allelic variants that may modify a WD phenotype.

Abstract
Background Approximately 90% of colorectal cancer (CRC) deaths are caused by tumors ability to migrate into the adjacent tissues and metastase into distant organs. More than 40 genes have been causally linked to the development of CRC but no mutations have been associated with metastasis yet. To identify molecular basis of CRC metastasis we performed whole-exome and genome-scale transcriptome sequencing of 7 liver metastases along with their matched primary tumours and normal tissue. Multiple, spatially separated fragments of primary tumours were analyzed in each case. Uniformly malignant tissue specimen were selected with macrodissection, for three samples followed with laser microdissection. Results > 100 sequencing coverage allowed for detection of genetic alterations in subpopulation of tumour cells. Mutations in KRAS, APC, POLE, and PTPRT, previously associated with CRC development, were detected in most patients. Several new associations were identified, including PLXND1, CELSR3, BAHD1 and PNPLA6. Conclusions We confirm the essential role of inflammation in CRC progression but question the mechanism of matrix metalloproteinases activation described in other work. Comprehensive sequencing data made it possible to associate genome-scale mutation distribution with gene expression patterns. To our knowledge, this is the first work to report such link in CRC metastasis context.

Abstract
BACKGROUND While histopathological evaluation remains the gold standard for diagnosis of prostate cancer (PCa), sampling errors remain a frequent problem; therefore, use of tissue biomarkers that can distinguish between benign and malignant prostate disease is a potentially beneficial diagnostic strategy. METHODS Deep sequencing of the miRNA transcriptome of 14 benign prostatic hyperplasia (BPH) and 60 cancerous and non-cancerous prostate samples extracted from 34 cancer-bearing prostates removed by prostatectomy was performed; of the latter 60 samples, 16, 21, and 23 samples contained <10%, >30%, and no dysplastic cells, respectively. The predictive value of selected miRNAs was then tested by quantitative reverse-transcribed PCR (qRT-PCR), using two separate chemistries, Exiqon and Taqman, to evaluate the tissue samples obtained by prostatectomy. Validation experiments were also performed for a subset of miRNAs by qRT-PCR of 87 prostate core biopsies. RESULTS We identified 123 miRNAs significantly dysregulated in PCa (adjusted P-values <0.05); 110 and 13 miRNAs were dysregulated only in cancerous samples and non-cancerous samples extracted from cancer-bearing prostates, respectively, while 31 were dysregulated regardless of the dysplastic cell content of the studied specimens. The clinical utility of eight selected miRNAs was analyzed using the same sample set with two qRT-PCR chemistries. Measurable qRT-PCR signals were obtained for seven and six miRNAs using the Exiqon and Taqman chemistries, respectively, and expression levels of six and four of these miRNAs differed significantly between BPH and PCa samples, regardless of dysplastic cell content. Validation experiments on core biopsies using qRT-PCR confirmed differential expression between BPH and PCa of four miRNAs (miR-187-3p, miR-183-5p, miR-32-5p, and miR-141-5p) using the Exiqon and one miRNA (miR-187-3p) with the Taqman chemistry. CONCLUSIONS Our sequencing analyses identified several candidate diagnostic miRNAs and confirmed some which have previously been reported as diagnostic in prostate malignancy. The results of this study suggest also that some of selected miRNAs can differentiate between non-malignant and malignant prostates even when neoplastic cells are missing from the studied specimen.

Abstract
BACKGROUND & AIMS Macro-aspartate aminotransferase (macro-AST) manifests as a persistent elevation of AST levels, because of association of the protein with immunoglobulins in the circulation. Macro-AST is a rare, benign condition without a previously confirmed genetic basis. METHODS Whole exome sequencing (WES)-based screening was performed on 32 participants with suspected familial macro-AST, while validation of variants was performed on an extended cohort of 92 probands and 1,644 healthy controls using Taqman genotyping. RESULTS A missense variant (p.Gln208Glu, rs374966349) in glutamate oxaloacetate transaminase 1 (GOT1) was found, as a putative causal variant predisposing to familial macro-AST. The GOT1 p.Gln208Glu mutation was detected in 50 (54.3%) of 92 probands from 20 of 29 (69%) families, while its prevalence in healthy controls was only 0.18%. In silico analysis demonstrated that the amino acid at this position is not conserved among different species and that, functionally, a negatively charged glutamate on the GOT1 surface could strongly anchor serum immunoglobulins. CONCLUSIONS Our data highlight that testing for the p.Gln208Glu genetic variant may be useful in diagnosis of macro-AST. LAY SUMMARY Higher than normal levels of aspartate aminotransferase (AST) in the bloodstream may be a sign of a health problem. Individuals with macro-AST have elevated blood AST levels, without ongoing disease and often undergo unnecessary medical tests before the diagnosis of macro-AST is established. We found a genetic variant in the GOT1 gene associated with macro-AST. Genetic testing for this variant may aid diagnosis of macro-AST.

Abstract
Abstract
SWI/SNF is a multiprotein chromatin remodeler with ATP-dependent activities leading to selective gene expression, DNA repair, recombination and replication. Various sequencing efforts indicated that nearly 20% of cancers bear mutations in at least one subunit of the complex. One of the crucial regulators of the complex is SMARCA4, a member of SWI/SNF family of helicases with ATPase activities, which are thought to regulate transcription of certain genes by altering the chromatin structure. SMARCA4 is mutated in virtually all cases of small cell carcinoma of the ovary and SMARCA4 is fourth the most frequently mutated gene in lung adenocarcinoma. High occurrence of inactivating mutations prompted several screenings projects focused on synthetic lethality interactions with other proteins, which led to the identification of SMARCA2 as an essential gene in SMARCA4 mutated cancers. This vulnerability could be potentially exploited therapeutically and several groups managed to identify potent ligands of SMARCA2 bromodomain. Surprisingly these molecules were inactive in SMARCA4 mutant cells, however additional studies indicated that ATPase rather than bromodomain is a target for novel compounds with anticancer activities. Overall, these results revealed functional complexity of SMARCA2 and SMARCA4 in cancer cells. In order to characterize molecular consequences of SMARCA2 silencing in SMARCA4 mutant lung adenocarcinoma cells, we have carried out a series of gene knockdown experiments, followed by transcriptional profiling by RNAseq and analysis of posttranslational histone modifications. These studies indicated rapid and irreversible loss of viability in SMARCA4 mutant cells after SMARCA2 gene silencing. Interestingly double SMARCA2/SMARCA4 knockdown in SMARCA4 WT cells has not resulted in lowered viability. Transcriptional profiling of SMARCA2 knockdown in SMARCA4 mutated cells revealed broad, predominantly repressory effects on gene expression levels. Gene set enrichment analysis showed significant inhibitory effects of SMARCA2 knockdown, particularly on transcripts which could be induced after reintroduction of SMARCA4. Furthermore MS/MS analysis indicated global rearrangements in histone epigenetic marks. These results prompted us to test activity of small-molecule epigenetic modulators, including DNA Methyltransferases (DNMTs), Histone Acetyltransferases (HATs), Histone Deacetylases (HDACs), Histone Methyltransferases (HMTs), Histone Demethylases (HDMs) and a distinct set of chromatin readers, bromodomains. Differential activity of these compounds provides a strong basis for novel strategies for the treatment of cancers with loss-of-function mutations of SMARCA4.

Abstract
Background Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are forms of hepatic autoimmunity, and risk for both diseases has a strong genetic component. This study aimed to define the genetic architecture of PBC and PSC within the Polish population. Methods Subjects were 443 women with PBC, 120 patients with PSC, and 934 healthy controls recruited from Gastroenterology Departments in various Polish hospitals. Allelotyping employed a pooled-DNA sample-based genome-wide association study (GWAS) approach, using Illumina Human Omni2.5-Exome BeadChips and the following novel selection criteria for risk loci: blocks of at least 10 single nucleotide polymorphisms (SNPs) in strong linkage disequilibrium, where the distance between each adjacent SNP pair in the block was less than 30 kb, and each SNP was associated with disease at a significance level of P < 0.005. A selected index SNP from each block was validated using TaqMan SNP genotyping assays. Results Nineteen and twenty-one SNPs were verified as associated with PBC and PSC, respectively, by individual genotyping; 19 (10/9, PBC/PSC) SNPs reached a stringent (corrected) significance threshold and a further 21 (9/12, PBC/PSC) reached a nominal level of significance (P < 0.05 with odds ratio (OR) > 1.2 or < 0.83), providing suggestive evidence of association. The SNPs mapped to seven (1p31.3, 3q13, 6p21, 7q32.1, 11q23.3, 17q12, 19q13.33) and one (6p21) chromosome region previously associated with PBC and PSC, respectively. The SNP, rs35730843, mapping to the POLR2G gene promoter (P = 1.2 × 10-5, OR = 0.39) demonstrated the highest effect size, and was protective for PBC, whereas for PSC respective SNPs were: rs13191240 in the intron of ADGRB3 gene (P = 0.0095, OR = 0.2) and rs3822659 (P = 0.0051, OR = 0.236) along with rs9686714 (P = 0.00077, OR = 0.2), both located in the WWC1 gene. Conclusions Our cost-effective GWAS approach followed by individual genotyping confirmed several previously identified associations and discovered new susceptibility loci associated with PBC and/or PSC in Polish patients. However, further functional studies are warranted to understand the roles of these newly identified variants in the development of the two disorders.

Abstract
INTRODUCTION Endometrial and cervical carcinoma are common neoplasms in gynecological oncology. The prognosis and treatment depend on the stage of the cancer according to the FIGO staging system. Stage IAl may be treated by hysterectomy or even local surgical procedures. For Stage IA2, radical hysterectomy and lymphadenectomy must be performed. Lymph node metastasis is an important prognostic factor in both cancers, however lymphadenectomy is associated with long-term complications. Thanks to the sentinel lymph node biopsy (SLNB), we can more accurately discover the staging of the primary tumor, and in case of sentinel lymph node (SLN) negative patients, can resign regional lymphadenectomy. Some researchers claim that new techniques such as indocyanine green (ICG) and endoscopic near-infrared fluorescence imaging for sentinel node mapping can be used instead of the traditional techniques. AIM To establish the role of sentinel node mapping technique in endometrial and cervical cancer. MATERIAL AND METHODS A retrospective study of medical records of five patients with cervical cancer (first group) Stage I and nine patients (second group) who underwent laparoscopic radical hysterectomy and SLNB or group of lymph nodes. These procedures were performed at Gynecology Department of the District Hospital in Garwolin. RESULTS All lymph nodes were clear of metastases. All patients after histopathological diagnosis were finally referred to the Cancer Centre and Institute of Oncology due to consultation or for further treatment. CONCLUSION Based on the present first results and literature review, intracervical ICG injection with fluorescence imaging seems to be the best SLN mapping technique, because of its simplicity, safety, and overall lower cost. More data is required to determine if the nodes identified with this technique are able to predict metastatic disease.

Abstract
Genome-wide mechanisms that coordinate expression of subsets of functionally related genes are largely unknown. Recent studies show that receptor tyrosine kinases and components of signal transduction cascades including the extracellular signal-regulated protein kinase (ERK), once thought to act predominantly in the vicinity of plasma membrane and in the cytoplasm, can be recruited to chromatin encompassing transcribed genes. Genome-wide distribution of these transducers and their relationship to transcribing RNA polymerase II (Pol2) could provide new insights about co-regulation of functionally related gene subsets. Chromatin immunoprecipitations (ChIP) followed by deep sequencing, ChIP-Seq, revealed that genome-wide binding of epidermal growth factor receptor, EGFR and ERK pathway components at EGF-responsive genes was highly correlated with characteristic mitogen-induced Pol2-profile. Endosomes play a role in intracellular trafficking of proteins including their nuclear import. Immunofluorescence revealed that EGF-activated EGFR, MEK1/2 and ERK1/2 co-localize on endosomes. Perturbation of endosome internalization process, through the depletion of AP2M1 protein, resulted in decreased number of the EGFR containing endosomes and inhibition of Pol2, EGFR/ERK recruitment to EGR1 gene. Thus, mitogen-induced co-recruitment of EGFR/ERK components to subsets of genes, a kinase module possibly pre-assembled on endosome to synchronize their nuclear import, could coordinate genome-wide transcriptional events to ensure effective cell proliferation.

Abstract
Carcinoma of the cervix is the most common malignancy associated with pregnancy. The frequency of cervical cancer is estimated to range from 1/1,200 to 1/10,000 pregnancies. The symptoms of cervical cancer are not specific and can be mistaken as frequent symptoms associated with other pathologies of pregnancy. The diagnostic procedure is similar to the one which should be proposed to unpregnant women. The treatment of cervical cancer depends on gestational age. The final treatment and further prognosis is carried out after delivery. The authors present the case of a 35-year-old woman at 34 weeks of gestation diagnosed with Stage IB cervical cancer. Treatment was delayed until fetal maturity and an elective cesarean section was performed at 36 weeks' gestation, followed by a radical hysterectomy, bilateral salpingo-oophorectomy, and a pelvic lymphadenectomy. Patient underwent adjuvant radiochemotherapy and brachytherapy. Recurrence of neoplastic process was found after one year.

Abstract
Contrast-enhanced computed tomography (CECT) and positron emission tomography with 18-FDG (FDG-PET/CT) are used to identify malignant solitary pulmonary nodules. The aim of the study was to evaluate the accuracy of CECT and FDG-PET/CT in diagnosing the etiology of solitary pulmonary nodule (SPN). Eighty patients with newly diagnosed SPN >8 mm were enrolled. The patients were scheduled for either or both, CECT and FDG-PET/CT. The nature of SPN (malignant or benign) was determined either by its pathological examination or radiological criteria. In 71 patients, the etiology of SPN was established and these patients were included in the final analysis. The median SPN diameter in these patients was 13 mm (range 8-30 mm). Twenty-two nodules (31%) were malignant, whereas 49 nodules were benign. FDG-PET/CT was performed in 40 patients, and CECT in 39 subjects. Diagnostic accuracy of CECT was 0.58 (95% confidence interval [CI] 0.41-0.74). The optimal cutoff level discriminating between malignant and benign SPN was an enhancement value of 19 Hounsfield units, for which the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of CECT were 100%, 37%, 32%, and 100%, respectively. Diagnostic accuracy of FDG-PET/CT reached 0.9 (95% CI 0.76-0.9). The optimal cutoff level for FDG-PET/CT was maximal standardized uptake value (SUV max) 2.1. At this point, the sensitivity, specificity, PPV, and NPV were 77%, 92%, 83%, and 89%, respectively. The diagnostic accuracy of FDG-PET/CT is higher than that of CECT. The advantage of CECT is its high sensitivity and negative predictive value.

Abstract
Altered epigenetic mechanisms, similar to gene mutations, contribute to the pathogenesis and molecular heterogeneity of neoplasms, including colorectal cancer (CRC). Enhancer of zeste 2 (EZH2) is a histone methyltransferase, which is involved in epigenetic gene silencing and is aberrantly expressed in CRC. Therefore, the identification of the genes regulated by EZH2 in CRC is important to improve current understanding of its role in cancer epigenetics. The present study used chromatin immunoprecipitation (ChIP) followed by deep sequencing to assess genome-wide EZH2‑DNA interactions in healthy or CRC mucosa samples. In total, 86.9/61.6 and 92.5/62.6 million tags were sequenced/mapped in healthy and CRC mucosa samples, respectively. The EZH2-binding densities were correlated with transcriptomic datasets and this demonstrated that the claudin-23 (CLDN23) gene, which encodes a component of cell-cell adhesion structures, was occupied by EZH2 and significantly silenced in CRC tissue. The measurement of DNA methylation at the CLDN23 promoter using pyrosequencing excluded the possibility that silencing of this gene in CRC patient samples was a result of DNA hypermethylation. Following treatment of the Colo205 and HT-29 CRC cell lines, with the EZH2 inhibitor, GSK126, the level of histone H3 lysine 27 trimethylation (H3K27me3) was reduced and the mRNA and protein expression levels of CLDN23 were increased. ChIP analysis confirmed that the level of H3K27m3 along the CLDN23 gene was decreased in the GSK126-treated cell lines. Furthermore, ChIP analysis of these samples detected histone H3 lysine 4 trimethylation (H3K4me3) at the CLDN23 promoter, demonstrating that the balance between H3K27me3 and H3K4me3 may underlie the regulation of the expression of CLDN23. The present study demonstrated an epigenetic link between the activity of the EZH2 methyltransferase at the CLDN23 locus and the expression of CLDN23 in CRC tissue.

Abstract
A total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is considered the surgery of choice for definitive management of familial adenomatous polyposis (FAP) and some patients with ulcerative colitis (UC). However, this surgical treatment is often associated with pouchitis, a long-term complication that occurs mostly in UC patients. The purpose of this study was to better define the molecular background of pouchitis. A microarray-based survey was performed using pouch mucosal samples collected from 28 and 8 patients undergoing surgery for UC and FAP, respectively. There were 4,770 genes that significantly differentiated uninflamed from inflamed mucosal samples, and their functional features were represented mostly by metabolic and cell proliferation pathways. In contrast, functional analyses of aberrantly expressed genes between UC and FAP samples, irrespective of mucosal inflammation status, revealed multiple pathways and terms that were linked to changes in immune response. Interestingly, the comparison of uninflamed UC and FAP samples identified a set of 29 altered probe sets, including an inflammation-related transcript encoding a Charcot-Leyden crystal (CLC) protein. The most distinct changes in gene expression profiles differentiating uninflamed UC and FAP pouch mucosal samples were attributed to the Gene Ontology category innate immune response. Our study confirmed that alterations in immune responses can be found between patients who underwent surgery for UC and FAP, independent of the pouch inflammation status. This observation may be important when managing IPAA patients.

Abstract
Although mitochondrial dysfunction is implicated in the pathogenesis of obesity, the molecular mechanisms underlying obesity-related metabolic abnormalities are not well established. We performed mitochondrial quantitative proteomic and whole transcriptome analysis followed by functional annotations within liver and skeletal muscles, using fasted and non-fasted 16- and 48-week-old high-fat diet (HFD)-fed and normal diet-fed (control group) wild-type C56BL/6J mice, and hyperphagic ob/ob and db/db obese mice. Our study identified 1,675 and 704 mitochondria-associated proteins with at least two peptides in liver and muscle, respectively. Of these, 221 liver and 44 muscle proteins were differentially expressed (adjusted p values ≤ 0.05) between control and all obese mice, while overnight fasting altered expression of 107 liver and 35 muscle proteins. In the liver, we distinguished a network of 27 proteins exhibiting opposite direction of expression changes in HFD-fed and hyperphagic mice when compared to control. The network centered on cytochromes P450 3a11 (Cyp3a11) and 4a14 (Cyp4a14), and fructose-bisphosphate aldolase B (Aldob) proteins which bridged proteins cluster involved in Metabolism of xenobiotics with proteins engaged in Fatty acid metabolism and PPAR signaling pathways. Functional annotations revealed that most of the hepatic molecular alterations, which characterized both obesity and fasting, related to different aspects of energy metabolism (such as Fatty acid metabolism, Peroxisome, and PPAR signaling); however, only a limited number of functional annotations could be selected from skeletal muscle data sets. Thus, our comprehensive molecular overview revealed that both obesity and fasting states induce more pronounced mitochondrial proteome changes in the liver than in the muscles.

Abstract
It is estimated that about 5–10% of ovarian and 2–5% of all breast cancer patients are carriers of a germline BRCA1 or BRCA2 gene mutation. Most families with detected BRCA1 or BRCA2 gene mutation are qualified for molecular testing on the basis of family history of breast or ovarian cancers. The purpose of our study was to establish the frequency of positive family history of cancer in a series of Polish consecutive breast and ovarian cancer patients in two groups, with and without the BRCA1 gene mutations. We analysed the prevalence of four of the most common BRCA1 mutations: 5382insC (c.5266dupC), 300T>G (p.181T>G), 185delAG (c.68_69delAG) and 3819del5 (c.3700_3704del5). The patient group consisted of 1,845 consecutive female breast and 363 ovarian cancer cases. 19 out of 37 (51%) of BRCA1-positive ovarian cancer patients and 21 out of 55 (39%) BRCA1-positive breast cancer had negative family history of breast and/or ovarian cancer among first- and second-degree relatives. In ovarian cancer patients, negative family history was more frequent in those with 300T>G BRCA1 gene mutation than in 5382insC carriers. This finding indicates the necessity of searching for 300T>G mutation in families with a single diagnosis of ovarian cancer in family. The high frequency of mutations detected in breast cancer patients lacking obvious family history shows that breast cancer patients should be qualified for genetic testing on the basis of wide clinical and pathological criteria.

Abstract
Signaling through interleukin-7 receptor (IL-7R) is essential for regulation of T-cell homeostasis and survival. Previously, we and others have found diminished IL-7R levels in simian immunodeficiency virus (SIV) - infected non-human primates and human immunodeficiency virus (HIV) - infected patients. To date, it remains unknown whether changes in IL-7R expression could also be linked to non-infectious inflammatory diseases such as asthma or anti-inflammatory drug use. Here, we investigated through flow cytometry the levels of IL-7R expression on CD4+ and CD4- T-cells in asthmatic patients in relation to disease severity, immune status and glucocorticoid (GC) use. In addition, we sought to evaluate the effects of in vivo and in vitro GC treatment on IL-7R expression in both asthmatic patients and SIV-infected non-human primates. We demonstrated that expression of IL-7R on peripheral blood CD4+ T-cells was significantly decreased in clinically stable GC-naive mild and moderate asthmatic patients. Accordingly, the development of asthmatic reaction following bronchial allergen challenge performed in sensitized subjects was associated with a significant drop in levels of IL-7R on circulating CD4+ T-cells. In contrast, CD4+ T-cells from both, mild and moderate, but not severe asthmatics, treated with inhaled GC displayed levels of IL-7R similar to that seen in healthy controls. We did not find significant differences with serum or sputum interleukin-7 levels among healthy controls and GC-naïve and GC-treated asthmatic patients. Furthermore, both in vitro GC treatment and short-term oral GC administration to asthmatic patients resulted in a significant enhancement of IL-7R. Similarly, we demonstrated that GC-stimulated T-cells from SIV-infected non-human primates up-regulated IL-7R expression. Accordingly, experimental short-term systemic in vivo administration of GC to SIV-infected macaques led to enhancement of IL-7R expression on circulating T-cells. Our data indicate that GC bear potential to recover diminished IL-7R expression, as well in asthma as in lentiviral infection.

Abstract
Peripheral blood monocyte (PBM) subsets play different roles in inflammatory response and tissue remodelling. The aim of this study was to investigate how allergen challenge affects the number of circulating PBMs in Dermatophagoides pteronyssinus (Dp) allergic patients (Dp-APs). Among 34 Dp-APs challenged, in 22 patients significant bronchoconstriction was demonstrated [responders (Rs)], while in 12, only upper respiratory symptoms were seen [non-responders (NRs)]. Twelve healthy, non-atopic subjects were used as controls (HCs). Expression of CD14, CD16 and CCR4 was evaluated by flow cytometry on the whole-blood samples before (T(0) ), 6 h (T(6) ) and 24 h (T(24) ) after the challenge. Plasma concentrations of CCL2, CX3CL1 and CCL17 were evaluated using ELISA. At T(0) , the mean percentage of CD14++ CD16+ PBMs in Rs (35.4%; 95%CI 26.9-43.9%) was significantly greater than in HCs (14.6%; 95%CI 7.3-21.8%; P = 0.006) and in NRs (17.5%; 95%CI 9.6-25.4%; P = 0.001). The baseline number of CD14++ CD16+ PBMs correlated with airway hyper responsiveness (AHR) (r = -0.507; 95%CI -0.834 to -0.432, P < 0.001). At T(24) , the number of CD14++ CD16+ PBMs significantly decreased in Rs but not in NRs and the numbers inversely correlated with plasma CCL17 concentration. Changes in the number of circulating CD14++ CD16+ cells after Dp challenge correlated with AHR (r = 0.706, 95%CI 0.43-0.861; P < 0.001). In all subjects, the greatest expression of CCR4 was found on CD14++ CD16+ PBMs. Expansion of CD14++ CD16+ monocytes in the peripheral blood with subsequent mobilization of those cells after allergen challenge may facilitate the development of AHR in Dp-APs.

Abstract
PURPOSE Aggressive intervention against the bladder wall during transurethral resection of bladder tumors (TURBT) causes damage and leakage from blood vessels to the bladder lumen. The aim of this study was to determine whether TURBT could increase the level of circulating urothelial cells. METHODS Expression of tumor markers, discriminative for nucleated blood cells and urothelium, was evaluated by quantitative (q) RT-PCR on RNA isolated from peripheral blood samples of 51 patients who underwent TURBT for ≥cT1c bladder tumors. RESULTS Four of 14 studied genes, epidermal growth factor receptor (EGFR), Collagen α-1(I) chain, Mast/stem cell growth factor receptor (KIT) and CD47, exhibited significant differences in gene expression between controls and cancer patients. While TURBT did not significantly increase the number of PCR-positive results of any transcripts, positive RT-PCR detection for EGFR was significantly less frequent on day 30 compared to results obtained before surgery. CONCLUSIONS Although the results of our study do not provide evidence for increased tumor cell release into the peripheral blood after TURBT, they seem to indicate that EGFR mRNA measurement in the blood may provide useful information for urologists.

Abstract
The purpose of our study was to establish the frequency and distribution of the four most common BRCA1 mutations in Polish general population and in a series of breast cancer patients. Analysis of the population frequency of 5382insC (c.5266dupC), 300T >G (p.181T >G), 185delAG (c.68_69delAG) and 3819del5 (c.3700_3704del5) mutations of the BRCA1 gene were performed on a group of respectively 16,849, 13,462, 12,485 and 3923 anonymous samples collected at birth in seven Polish provinces. The patient group consisted of 1845 consecutive female breast cancer cases. The most frequent BRCA1 mutation in the general population was 5382insC found in 29 out of 16,849 samples (0.17%). 300T >G and 3819del5 mutations were found in respectively 11 of 13,462 (0.08%) and four of 3923 (0.1%) samples. The population prevalence for combined Polish founder 5382insC and 300T >G mutations was 0.25% (1/400). The frequencies of 5382insC and 300T >G carriers among consecutive breast cancer cases were, respectively, 1.9% (35/1845) and 1.2% (18/1486). Comparing these data with the population frequency, we calculated the relative risk of breast cancer for 5382insC mutation at OR = 17 and for 300T >G mutation at OR = 26. Our results, based on large population studies, show high frequencies of founder 5382insC and 300T >G BRCA1 mutations in Polish general population. Carriage of one of these mutations is connected with a very high relative risk of breast cancer.

Abstract
Background PALB2 protein was recently identified as a partner of BRCA1 and BRCA2 which determines their proper function in DNA repair. Methods Initially, the entire coding sequence of the PALB2 gene with exon/intron boundaries was evaluated by the PCR-SSCP and direct sequencing methods on 70 ovarian carcinomas. Sequence variants of interest were further studied on enlarged groups of ovarian carcinomas (total 339 non-consecutive ovarian carcinomas), blood samples from 334 consecutive sporadic and 648 consecutive familial breast cancer patients, and 1310 healthy controls from central Poland. Results Ten types of sequence variants were detected, and among them four novel polymorphisms: c.2996+58T>C in intron 9; c.505C>A (p.L169I), c.618T>G (p.L206L), both in exon 4; and c.2135C>T (A712V) in exon 5 of the PALB2 gene. Another two polymorphisms, c.212-58A>C and c.2014G>C (E672Q) were always detected together, both in cancer (7.5% of patients) and control samples (4.9% of controls, p = 0.2). A novel germline truncating mutation, c.509_510delGA (p.R170fs) was found in exon 4: in 2 of 339 (0.6%) unrelated ovarian cancer patients, in 4 of 648 (0.6%) unrelated familial breast cancer patients, and in 1 of 1310 controls (0.08%, p = 0.1, p = 0.044, respectively). One ovarian cancer patient with the PALB2 mutation had also a germline nonsense mutation of the BRCA2 gene. Conclusions The c.509_510delGA is a novel PALB2 mutation that increases the risk of familial breast cancer. Occurrence of the same PALB2 alteration in seven unrelated women suggests that c.509_510delGA (p.R170fs) is a recurrent mutation for Polish population.

Abstract
Glucocorticoids (GCS) are capable of stimulating the secretion of interleukin (IL)-10 by leucocytes; however, the potential of GCS to modulate leucocyte susceptibility to IL-10-mediated actions has not yet been studied. In the current paper, we performed a detailed cross-sectional analysis of IL-10 receptor (IL-10R) expression by CD4(+) and CD8(+) T cells, natural killer (NK) cells, monocytes and neutrophils. Next, we analysed the effects of short-term oral GCS treatment on surface IL-10R expression by various leucocyte subpopulations in asthmatic patients. All leucocyte subsets studied presented with substantial levels of surface IL-10R. The highest levels of IL-10R were found on monocytes, predominantly with CD14(2+)CD16(+) and CD14(+)CD16(+) phenotypes, and on CD4(+)CD25(high) T cells. In contrast, levels of IL-10R on CD8(+) T cells, NK cells and neutrophils were significantly lower and similar to each other in intensity. GCS treatment resulted in a significant decrease of IL-10R expression on all analysed peripheral blood leucocyte subsets. Our data suggest that down-regulation of IL-10R could counterbalance the otherwise suppressive action of GCS.

Abstract
The objective of the present study was to evaluate the prevalence of chronic cough causes and to compare the efficacy of two diagnostic approaches used in ambulatory vs. hospitalized setting. Eighty patients with chronic cough, 40 in each group, were enrolled into the study. The etiology of cough was determined on medical history and on either basic (in out-patients) or detailed (in in-patients) investigations on most common causes of chronic cough. We diagnosed etiology of cough in all subjects. The most frequent causes of cough were gastroesophageal reflux disease (GERD) and upper airway cough syndrome (UACS). Nonasthmatic eosinophilic bronchitis (NAEB) and multiple cough causes were recognized more often in hospitalized patients (P<0.05). We conclude that the main causes of chronic cough were GERD and UACS. An extensive diagnostic approach allows recognizing NEAB more frequently and reveals the complex nature of chronic cough.

Abstract
BACKGROUND Recent studies in rodents revealed that regulatory T cells (T reg cells) with CD4+CD25+ phenotype can exert suppressive effects on experimentally-induced allergic airway inflammation and airway hyper-reactivity. It is unclear however, whether modulations of bronchoconstriction responses in human subjects might be related to T reg cells. We report here for the first time the changes in frequency of circulating lymphocytes with putative T reg cell phenotype (CD4+CD25+CD127low) in relation to bronchoconstriction phenotype following an intrabronchial allergen challenge. MATERIAL AND METHODS Thirty-one house dust mite sensitive patients were challenged with Dermatophagoides pteronyssinus extract (Dp). Eleven isolated early responders (IER) were compared with nine dual (early and late) responders (DR) and to 11 non-responders (NR). Frequencies of peripheral blood CD4+CD25+CD127low lymphocytes were assessed in all groups of patients by using three-parameter flow cytometry before, and six and 24 h, after allergen inhalation. RESULTS At baseline, frequencies of CD4+CD25+CD127low lymphocytes were not statistically different among NR, IER and DR. When all individuals were analyzed together, a statistically significant decrease in frequency of CD4+CD25+CD127low lymphocytes was observed 6 h after the bronchial challenge. Interestingly, such a pattern was found consistently only in NR, while IER and DR displayed varying responses resulting in a trend similar to that of NR. Twenty-four hours after the bronchial challenge, frequencies of CD4+CD25+CD127low lymphocytes in all groups tended to return to baseline values. CONCLUSIONS Our data indicate that bronchial allergen inhalation in sensitive patients (predominantly in those who did not develop significant bronchoconstriction) is associated with a decrease of proportion of peripheral lymphocytes with regulatory T cell phenotype.

Abstract
The present case study reports a case of chronic cough and cough syncope associated with frequent premature ventricular complexes (PVCs). Careful analysis of cough-related symptoms and ECG monitoring led to the suspicion of PVC-induced cough. A coincidence between PVCs and episodes of cough was also documented by a portable multichannel recorder. Moreover, Doppler echocardiography revealed a PVC-induced transient increase in the pulmonary artery blood flow. After exclusion of other possible aetiologies, complete relief of chronic cough and cough syncope was achieved by radiofrequency ablation of the arrhythmogenic focus located in the right ventricular outflow tract. Premature ventricular complexes should be considered as a cause of chronic cough and cough syncope and an interdisciplinary cooperation can lead to successful diagnosis and treatment of this condition.

Abstract
BACKGROUND Cannabinoid receptors CB1 and CB2 are part the endocannabinoid system that plays an important role in the process of proliferation and apoptosis of different neoplastic cells. B-cell chronic lymphocytic leukaemia is one of the diseases in which these processes are altered. AIM The aim of our study was the assessment of cannabinoid receptor expression on the B-lymphocytes in bone marrow trephine biopsy from leukaemic patients at diagnosis and after purine analogue treatment. METHODS The biopsy was taken routinely and standard immunohistochemical staining procedure for paraffin embedded sections was applied. The cannabinoid receptors were detected using specific primary polyclonal antibody anti-CB1 and anti-CB2. Additionally, an existence of cannabinoid receptors was confirmed by flow cytometry. RESULTS The results showed that the expression of CB1 receptor on the surface of neoplastic cells was lower than that of CB2 (17.0+/-3.1% and 92.1+/-1.7% respectively, p<0.001). Nine of the patients responded to applied treatment with a reduction in leukaemic infiltration (77.2+/-6.9% to 30.2+/-6.5%, p=0.007) and CB1 receptor expression (24.4+/-4.8% to 8.6+/-2.9%, p=0.01), but there was no change in CB2 expression (91.7+/-2.7% vs 90.9+/-2.8%, p=0.69). Four patients without remission expressed even greater number of the receptors. In all of the cases both cannabinoid receptor types antibodies gave positive reaction. Furthermore, the existence of cannabinoid receptors on neoplastic lymphocytes was confirmed by flow cytometry. CONCLUSION The study provides original evidence for the existence of cannabinoid receptors on B-lymphocytes in chronic lymphocytic leukaemia patients. The receptors are thought to be a new structure that can modify the course of the disease and may be considered as a new target in leukaemia treatment.

Abstract
An impairment of in vitro cytotoxicity and tumoricidal function of alveolar macrophages (AMs) in patients with lung cancer was reported in a number of studies. The aim of our study was to evaluate the expression of intercellular adhesion molecule-1 (ICAM-1) on AMs after stimulation with interferon-gamma (IFN-gamma) in patients with non-small cell lung cancer (NSCLC). The study was performed in 13 patients with NSCLC, 6 patients with various nonmalignant pulmonary diseases, and 6 healthy volunteers. AMs were isolated from bronchoalveolar lavage fluid (BALF) by adherence and then cultured with or without IFN-gamma for 24 h. The expression of ICAM-1 on AMs was analyzed by flow cytometry. Stimulation with IFN-gamma caused increased expression of ICAM-1 on AMs in all studied groups (p < 0.05). The degree of the increase in ICAM-1 expression on AMs after IFN-gamma stimulation was significantly lower in patients with NSCLC compared with healthy volunteers (p = 0.002) or the other patients (p = 0.022). The results suggest impaired reactivity of ICAM-1 expression on AMs after stimulation with IFN-gamma in patients with NSCLC, which might be involved in functional defects of AMs in patients with NSCLC.

Abstract
The persistent expression of thymidylate synthase activity has previously been demonstrated not only in adult forms, but also in non-developing muscle larvae of Trichinella spiralis and T. pseudospiralis, pointing to an unusual pattern of cell cycle regulation, and prompting further studies on the developmental pattern of T. spiralis thymidylate synthase gene expression. The enzyme cDNA was cloned and sequenced, allowing the characterization of a single open reading frame of 307 amino acids coding for a putative protein of 35,582 Da molecular weight. The amino acid sequence of the parasite enzyme was analysed, the consensus phylogenetic tree built and its stability assessed. The aa sequence identity with thymidylate synthase was confirmed by the enzymatic activity of the recombinant protein expressed in E. coli. As compared with the enzyme purified from muscle larvae, it showed apparently similar Vmax value, but higher Km(app) values desscribing interactions with dUMP (28.8 microM vs. 3.9 microM) and (6RS,alphaS)-N(5,10)-methylenetetrahydrofolate (383 microM vs. 54.7 microM). With the coding region used as a probe, thymidylate synthase mRNA levels, relative to 18S rRNA, were found to be similar in muscle larvae, adult forms and newborn larvae, in agreement with muscle larvae cells being arrested in the cell cycle.

Abstract
Survivin is a member of the family of proteins, which inhibit apoptosis (inhibitor of apoptosis proteins - IAP). Expression of survivin was found in colorectal cancer, neuroblastoma, bladder cancer, non-small cell lung cancer, and breast cancer. There is some recent data indicating the correlation of poor prognosis and worse response to chemotherapy in patients with oesophageal squamous cell carcinoma (OSCC) expressing survivin. The aim of the present study was to assess survivin expression in cancerous tissue of patients with advanced OSCC and to test the potential correlation between survivin expression and clinicopathological data. Forty two patients (mean age 58.36+/-8.97 yrs), who were oesophagectomised due to squamous cell carcinoma of the thoracic oesophagus between 1998 and 2000, were retrospectively analysed. Cytoplasmic survivin expression, examined immunohistochemically, was found in 35 (83.33%) cases. No statistically significant correlation between survivin expression in the tumour and patients' gender, TNM stage, or vascular involvement was noted. The mean survival of patients with cytoplasmic survivin expression (17.81+/-5.51 months) was not statistically different to those with negative survivin staining (16+/-6.28 months) as assessed by Mantel-Cox test (p=0.49). Univariate regression analysis revealed UICC staging as the only predictor of survival in the analysed group (p<0.05). These results indicate that the cytoplasmic survivin expression does not seem to be the prognostic factor in advanced cases of OSCC.

Abstract
The linearity of ICAM- I expression on alveolar macrophages (AM) before and after INF-gamma stimulation in healthy and lung cancer subjects were compared. AM were collected by bronchoalveolar lavage and incubated with/without INF-gamma according to standard procedures. The harvested cells were analyzed by flow cytometry using monoclonal antibodies against leucocytes and macrophages. Only viable cells were analyzed. Stimulation with INF-gamma revealed two AM subpopulations of similar size differentiated in the intensity of ICAM-1 expression. They were not distinctly marked in every studied case. Our preliminary results did not confirm the previously reported decreasing reactivity of AMs after INF-gamma stimulation in lung cancer patients.

Abstract
Members of protein kinase C (PKC) family have been widely implicated in the regulation of cell proliferation, differentiation and survival. Increased protein C activity in malignant breast tissue and in most aggressive breast cancer cell lines suggests possible role of PKC in the development and progression of breast cancer. PKC may be therefore a target for breast cancer treatment. In our study we attempted to investigate the effect of: phorbol ester (PMA)-PKC activator, and bisindolylmaleimide II (GF II), a highly selective PKC inhibitor, on the proliferation as well as induction of apoptosis and necrosis in breast cancer cell line MDA-MB-231. Our results provide evidence for multidirectional effects of PKC on the proliferation of this type of breast cancer cells. The effects of both compounds were different after short time of exposition (1-3 h). PMA induced proliferation, while GF II showed an opposite effect. After 24 h, however, both compounds exhibited relatively high inhibitory effect on the proliferation and proved to be effective in induction of necrosis and apoptosis.

Abstract
The rate of apoptosis as well as expression of Bcl-2 and Bax was evaluated before and after induction therapy in leukocytes of 70 patients with acute myeloblastic leukemia (AML), retrospectively divided into group A (with longer survival) and group B (with shorter survival). We found, that leukocytes of untreated AML patients showed susceptibility to apoptosis similar to control cells. Marked increase in percentage of apoptotic leukocytes was observed after induction therapy exclusively in patients with longer survival, which was accompanied by better normalization of routine hematological parameters. In this group, the Bcl-2/Bax ratio was similar to the control and remained unchanged after treatment. In AML patients with shorter survival, a twofold increase in this ratio was observed both before and after the completion of induction therapy. In both groups of untreated patients, western blot analysis revealed the presence of prominent additional bands reacting with anti-Bcl-2 or anti-Bax antibody, which were undetectable in control leukocytes. After the therapy, these bands disappeared, especially in patients from group A. In conclusion, the lack of therapy-induced enhancement in leukocyte apoptosis, an increased ratio of Bcl-2/Bax as well as persistent presence of abnormal Bcl-2 and Bax protein bands after induction therapy in AML patients may be considered as factors associated with unfavorable clinical outcome.

Abstract
PURPOSE Previous in vitro studies have demonstrated that a potent antihypertensive agent ebelactone B inhibits cathepsin A/deamidase activity. The aim of our studies was to assess the effects of this inhibitor on cathepsin A activity in intact platelets and on platelet activation events. MATERIAL AND METHODS PRP or washed human platelets from healthy volunteers were pre-incubated with different concentrations of ebelactone B (1-10 microM) for 10-60 min. Cathepsin A activity in platelets was assayed colorimetrically using Cbz-Phe-Ala at pH 5.5. Expression of platelet activation markers GpIIb/IIIa and P-selectin on non-activated or agonist-activated platelets (ADP, TRAP) was measured by flow cytometry. RESULTS Pre-treatment of platelets for up to 60 minutes with 10 mumol/l ebelactone B, that effectively inhibits cathepsin A activity in platelet lysate, did not affect this activity in intact platelets. Exposure of PRP to 10 mumol/l ebelactone B alone, or before platelet activation with ADP or TRAP caused only a small but non-significant increase in P-selectin and GpIIb/IIIa expression on the platelet surface, as demonstrated by flow cytometry analysis. CONCLUSIONS The lack of cathepsin A inhibition by ebelactone B in intact platelets indicates that this inhibitor does not enter cells. Therefore, a potential antihypertensive significance of this compound may be through the inhibition of cathepsin A/deamidase released from activated or damaged cells. In vitro ebelactone B seems to exert no effect on platelet activation. Further studies are underway to determine whether ebelactone B administration affects platelet activation events in experimental model of hypertension in rats.

Abstract
The routine coagulation tests along with activated protein C resistance (APC-R) were studied in North-Eastern Poland women, applying for oral contraceptives. The APTT, PT and fibrinogen concentration were evaluated in 128 women, aged 20-40 years, by means of nephelometric method. For estimation of APC-R, Coatest APC Resistance V test was used. The abnormalities in routine coagulation test were found in 13.3% of studied women. The resistance to activated protein C was observed among 4.3% of women with normal results of routine coagulation tests. The thrombotic event occurred in one of five APC-R positive woman. There was no correlation between APC-V ratio and APTT, PT or fibrinogen values.

Abstract
Retinoids are a group of compounds which inhibit cell proliferation and induce cellular differentiation. The aim of this study was to compare the antiproliferative activity of various concentrations of 13-cis retinoic acid (isotretinoin) and all-trans retinoic acid (tretinoin) in a culture of the estrogen-sensitive human breast cancer cell line MCF-7. Evaluation was based on [3H]thymidine incorporation into the cancer cells and through immunocytochemical analysis of cell cycle-associated PCNA and Ki-67 protein expression. Both retinoids inhibited [3H]thymidine incorporation into the cancer cells most effectively at a concentration of 3x10(-3) M. Two basic substances used for line MCF-7 culture experiments, one stimulating - estradiol - and the other inhibiting - tamoxifen - were applied. Estradiol added to a culture containing decreasing concentrations of isotretinoin (from 3x10(-3) to 3x10(-8) M) caused a statistically significant reduction in the percentage of [3H]thymidine incorporation into the cancer cell line MCF-7, compared to the 17 beta estradiol group (189.25%+/-62.64, control=100%, p<0.05). In the group of decreasing tretinoin concentrations, statistically significant differences were found only at 3x10(-3), 3x10(-4) and 3x10(-8) M. Following culture supplementation with tamoxifen (1 microM), statistically significant differences were observed only at the highest concentrations of both retinoids (3x10(-3) and 3x10(-4) M). The evaluation of breast carcinoma cells with a positive immunocytochemical reaction to PCNA and Ki-67 has revealed that isotretinoin reduces their percentage in the most determined and statistically significant way (38.00%+/-2.58 and 39.25%+/-3.09), compared to the control group (86.50%+/-9.20 and 100%+/-3.87, p<0.001 and p<0.0001) and to the estradiol group (87.00%+/-6.79 and 86.10%+/-7.0, p<0.001). Apart from their blocking effect on the cell cycle, retinoids also induce the apoptotic pathway.

Abstract
The immunophenotype of peripheral blood lymphocytes was evaluated in 50 renal cell carcinoma (RCC) patients, before and after embolization. In RCC patients we have observed significant decrease in the total lymphocyte number as well as in T lymphocyte, their subpopulations and B lymphocyte number. Ten to twelve months after the treatment by embolization, significant increase in the total number of not only lymphocytes (p < 0.001), including T lymphocytes (p < 0.001), T-helper lymphocytes (p < 0.05), cytotoxic T lymphocytes (p < 0.05) and B lymphocytes (p < 0.05), but also an increase of NK cells number (p < 0.05) were found, compared to the values obtained before the treatment and reached the level observed in healthy subjects. Cytometric evaluation of peripheral blood lymphocytic phenotype in renal cell carcinoma patients can help evaluate the immune status of RCC patients as well as assess the embolization efficiency.
