Abstract
Previous research indicates that carcinogenesis involves disrupting the functions of numerous genes, including factors involved in the regulation of transcription and cell proliferation. For these reasons, in endometrial carcinogenesis, we decided to investigate the expression of TSG101 (a suppressor of tumor transformation) and LSF (a transcription factor involved in numerous cellular processes, such as cell cycle regulation, cell growth, development, and apoptosis). LSF may be involved in the regulation of TSG101 expression. The research material consisted of endometrial cancer samples from 60 patients. The control group consisted of normal endometrium samples donated by 60 women undergoing surgery for benign diseases of the female reproductive organs. The samples were subjected to immunohistochemical staining with antibodies specific to TSG101 and LSF. Specific antibodies were used to identify TSG101 and LSF in the examined histopathological preparations. An approximately 14-fold lower risk of endometrial cancer development was observed in patients with TSG expression in more than 75% of the assessed cells (4% vs. 36%; OR = 0.07; p = 0.0182). There was a four-fold lower risk of endometrial cancer development in patients with LSF expression in more than 50% of the assessed cells (32% vs. 64%; OR = 0.26; p = 0.0262). A more than three-fold lower risk of endometrial cancer development was observed in patients with LSF expression in more than 75% of the assessed cells (24% vs. 52%; OR = 0.29; p = 0.0454). Endometrial cancer was diagnosed in those with a lower level of TSG101 expression than in those with a cancer-free endometrium. Decreased expression of TSG101 may be a marker of endometrial cancer, and increased expression of LSF when diagnosed with endometrial cancer may indicate greater advancement of the disease. These markers might be used as diagnostic and prognostic markers-however, there is a lack of a correlation between them.

Abstract
A comparative analysis of the placental microbiome in pregnancies with late fetal growth restriction (FGR) was performed with normal pregnancies to assess the impact of bacteria on placental development and function. The presence of microorganisms in the placenta, amniotic fluid, fetal membranes and umbilical cord blood throughout pregnancy disproves the theory of the "sterile uterus". FGR occurs when the fetus is unable to follow a biophysically determined growth path. Bacterial infections have been linked to maternal overproduction of pro-inflammatory cytokines, as well as various short- and long-term problems. Proteomics and bioinformatics studies of placental biomass allowed the development of new diagnostic options. In this study, the microbiome of normal and FGR placentas was analyzed by LC-ESI-MS/MS mass spectrometry, and the bacteria present in both placentas were identified by analysis of a set of bacterial proteins. Thirty-six pregnant Caucasian women participated in the study, including 18 women with normal pregnancy and eutrophic fetuses (EFW > 10th percentile) and 18 women with late FGR diagnosed after 32 weeks of gestation. Based on the analysis of the proteinogram, 166 bacterial proteins were detected in the material taken from the placentas in the study group. Of these, 21 proteins had an exponentially modified protein abundance index (emPAI) value of 0 and were not included in further analysis. Of the remaining 145 proteins, 52 were also present in the material from the control group. The remaining 93 proteins were present only in the material collected from the study group. Based on the proteinogram analysis, 732 bacterial proteins were detected in the material taken from the control group. Of these, 104 proteins had an emPAI value of 0 and were not included in further analysis. Of the remaining 628 proteins, 52 were also present in the material from the study group. The remaining 576 proteins were present only in the material taken from the control group. In both groups, we considered the result of ns prot ≥ 60 as the cut-off value for the agreement of the detected protein with its theoretical counterpart. Our study found significantly higher emPAI values of proteins representative of the following bacteria: Actinopolyspora erythraea, Listeria costaricensis, E. coli, Methylobacterium, Acidobacteria bacterium, Bacteroidetes bacterium, Paenisporsarcina sp., Thiodiazotropha endol oripes and Clostridiales bacterium. On the other hand, in the control group statistically more frequently, based on proteomic data, the following were found: Flavobacterial bacterium, Aureimonas sp. and Bacillus cereus. Our study showed that placental dysbiosis may be an important factor in the etiology of FGR. The presence of numerous bacterial proteins present in the control material may indicate their protective role, while the presence of bacterial proteins detected only in the material taken from the placentas of the study group may indicate their potentially pathogenic nature. This phenomenon is probably important in the development of the immune system in early life, and the placental microbiota and its metabolites may have great potential in the screening, prevention, diagnosis and treatment of FGR.

Abstract
Chelidonium majus L. is a latex-bearing plant used in traditional folk medicine to treat human papillomavirus (HPV)-caused warts, papillae, and condylomas. Its latex and extracts are rich in many low-molecular compounds and proteins, but there is little or no information on their potential interaction. We describe the isolation and identification of a novel major latex protein (CmMLP1) composed of 147 amino acids and present a model of its structure containing a conserved hydrophobic cavity with high affinity to berberine, 8-hydroxycheleritrine, and dihydroberberine. CmMLP1 and the accompanying three alkaloids were present in the eluted chromatographic fractions of latex. They decreased in vitro viability of human cervical cancer cells (HPV-negative and HPV-positive). We combined, for the first time, research on macromolecular and low-molecular-weight compounds of latex-bearing plants in contrast to other studies that investigated proteins and alkaloids separately. The observed interaction between latex protein and alkaloids may influence our knowledge on plant defense. The proposed toolbox may help in further understanding of plant disease resistance and in pharmacological research.

Abstract
Background and Objectives: obesity and blood pressure disorders are one of the main risk factors for antenatal, intra, postpartum, and neonatal complications. In preeclampsia (PE), the placental hypoxia leads to vascular endothelium dysfunction, cell necrosis, and apoptosis. This condition is associated with the release of free fetal DNA (cffDNA) circulating in plasma. The disturbance of the efficiency of vasodilatation and blood pressure regulation in PE can be confirmed by analyzing the apelin, salusin, and prosalusin. This study aimed to assess the influence of obesity on cffDNA, and the effectiveness of maintaining normal blood pressure in patients with preeclampsia and gestational hypertension. Material and Methods: the research material was blood serum and oral mucosa swabs, obtained from 168 patients. Pregnant women were divided into the following: a control group (C)-67 women; a gestational hypertension group (GH)-35 patients; a preeclampsia with obesity group (PE + O) (pre-gravid BMI > 30)-23 patients. The rest were lean preeclamptic women (PE)-66 patients-(pre-gravid BMI < 25 in 43 women). Results: the cffDNA was observed in 1.50% of women in the C group, in 2.45% in the GH group, but in 18.18% of lean patients with preeclampsia. The cffDNA was detected in 58% of obese pregnant women with PE. The greater the placental hypoxia was in preeclampsia, the less efficient the hypotensive mechanisms, according to an analysis of the studied adipokines. The prosalusin concentration was significantly lower in the PE group with cffDNA than in the PE group without it (p = 0.008). Apelin was higher in the PE group with cffDNA (p = 0.006) compared to other groups. The same results were also observed in the subgroup with obesity. Conclusion: in preeclamptic women, obesity seems to act as an additive factor of placental damage by means of the dysregulation of hypotensive mechanisms.

Abstract
Thaumatin-like proteins (TLPs, osmotins) form a protein family which shares a significant sequence homology to the sweet-tasting thaumatin from the plant Thaumatococcus daniellii. TLPs are not sweet-tasting and are involved in response to biotic stresses and developmental processes. Recently it has been shown using a proteomic approach that the tuber extract from Corydalis cava (Papaveraceae) contains a TLP protein. The aim of this work was to characterize the structure and expression of TLP from C. cava tubers. The results obtained using a PCR approach with degenerate primers demonstrated a coding sequence of a novel protein, named CcTLP1. It consists of 225 aa, has a predicted molecular weight of 24.2 kDa (NCBI GenBank accession no. KJ513303) and has 16 strictly conserved cysteine residues, which form 8 disulfide bridges and stabilize the 3D structure. CcTLP1 may be classified into class IX of plant TLPs. The highest CcTLP1 expression levels were shown by qPCR in the stem of the plant compared to other organs and in the medium-size plants compared to other growth phases. The results confirm that CcTLP1 is expressed during plant growth and development until flowering, with a possible defensive function against different stress conditions.

Abstract
Viruses are intracellular pathogens which utilize a number of host metabolic processes for virus replication in addition to proteins which
are encoded for virus itself. Therefore, an effective antiviral drug must interfere with virus encoded proteins without affecting any cellular
metabolic processes. Unfortunately, many antiviral drugs that have an inhibitory effect on virus replication, also have an inhibitory effect on
molecular processes in infected, as well as uninfected, cells. There is currently no approved remedy for many viruses. Plants represent a large
potential source of antiviral agents, such as: alkaloids, flavonoids, phenolic acids, phenylpropanoids, lignins, terpenoids, quinine, tannins, thiophenes, polyacetylenes or proteins. Some of them possess broad spectrum of antiviral activity.

Abstract
Oncogenic viruses (oncoviruses) are implicated in approximately 12% of all human cancers. Currently, the viruses known to cause human cancer are: Hepatitis B and C viruses (HBV and HCV), Human Papillomaviruses (HPV), Merkel Cell Polyomavirus (MCV), Human Herpesvirus-8 (HHV-8), Epstein-Barr Virus (EBV) and Human T-cell lymphotropic virus-1 (HTLV-1). However, oncoviruses are not complete carcinogens, need additional factors andisplay different roles in transformation. Oncoviruses can directly disrupt important regulatory cell genes by inserting virus genom into the DNA of the host cell. They also contain their own genes that damage the regulation of the cell. Some viruses have v-onc that cause disregulation of cellular processes and can lead to cancerous growth.

Abstract
Background The potential HPV transmission route includes horizontal transmission “in utero” and vertical transmission from parents. Less is known about the role of child’s father as a potential source of HPV infection and involved in the pathogen’s epidemic chain. A possible consequence of perinatal infection includes HPV-related childhood diseases and carrying the risk of cervical cancer development in female offspring. In view of the evidence, studies of HPV co-occurrence in one or both parents and their offspring seem vital for the implementation of respective preventive measures. Consequently, the aim of this study was to determine the incidence of common HPV 16/18 infections in newborns and their parents, and to assess its role of the periconceptional transmission. Methods To determine the incidence of common HPV infections in newborns from single pregnancies and their parents. The study included 146 pregnant women, as well as their partners, and newborns. They were tested for the presence of HPV 16/18 DNA using the PCR method. HPV types 16 and/or 18 were identified using type-specific PCR primers. The quality of the extracted DNA was evaluated by PCR using PC03/PC04 β-globin-specific primers. The relationship between the presence of neonatal and parental HPV infection was analyzed using a multivariable regression model. Calculations were carried out with the Statistica 10. Results The presence of HPV DNA was detected in 19 (13,01%) newborns, 28 (19,18%) mothers, and 20 (13,7%) fathers. The viral DNA was detected in 14 newborns delivered by HPV-positive mothers (OR = 26,08; CI: 8,07-84,31, p < 0.001), 12 descendants of HPV-positive fathers (OR = 22,13; CI: 6,97-70,27, p < 0.001), and 10 children originating from two infected parents (OR = 24,20; CI: 6,84–85,57 p < 0.001). Those findings points to a increase risk of an acquired infection in newborns with HPV-positive parents. Conclusion Our findings suggest the possible role of the periconceptional transmission in the mode of acquired HPV 16/18 infections.

Abstract
BACKGROUND It has been shown that secondary metabolites occur in Chelidonium majus L. (C. majus) crude extract and milky sap (alkaloids such as berberine, coptisine, chelidonine, chelerythrine, sanguinarine, and protopine) are biologically active compounds with a wide spectrum of pharmacological functions. Berberine, an isoquinoline alkaloid extracted from plants, possesses a wide range of biological activities, including inhibition of growth of a variety of cancer cell lines. PURPOSE AND STUDY DESIGN In the present study, we investigated the potential anticancer effect of a protoberberine alkaloidal fraction (BBR-F) isolated from the medicinal plant C. majus on HeLa and C33A cervical cancer cells after light irradiation (PDT treatment). METHODS BBR-F was prepared from an ethanolic extract of stems of C. majus. Identification of alkaloidal compounds was performed using high-performance liquid chromatography - mass spectrometry (HPLC/ESI-MS) and nuclear magnetic resonance (NMR) spectroscopy. BBR-F was then biologically evaluated for its anticancer properties. Cytotoxic activity after PDT treatment and without light irradiation (dark cytotoxicity) was determined by colorimetric WST-1 assay. The impact of the protoberberine alkaloidal fraction on the morphology and function of the cells was assessed by fluorescence and confocal microscopy as well as by flow cytometric analysis. To investigate the proinflammatory effect of the extracted natural BBR-F, nitric oxide concentration was determined using the Griess method. RESULTS An effective reduction in HeLa and C33A cell viability was observed after PDT treatment of BBR-F treated cells. Furthermore, microscopic analysis identified various morphological changes in the studied cells that occurred during apoptosis. Apoptosis of HeLa and C33A cells was also characterized by biochemical changes in cell membrane composition, activation of intracellular caspases, disruption of the mitochondrial membrane potential (Δψm) and reactive oxygen species (ROS) generation. CONCLUSION Our results strongly suggest that the components of the natural plant protoberberine fraction (BBR-F) extracted from C. majus may represent promising novel photosensitive agents and can be applied in cancer photodynamic therapy as natural photosensitizers.

Abstract
BACKGROUND/AIMS The aim of this study was to associate children's growth disorders with polymorphisms detected in the P1 promoter region of IGF1 (including SNP and (CA) n microsatellite repeat polymorphism) and IGF1 and IGFPB3 levels. METHODS IGF-1 gene P1 promoter polymorphism was analyzed in DNA obtained from the blood of 51 children with growth disorders and 50 healthy children without growth disorders by means of PCR-SSCP and sequencing. RESULTS Among children with growth disorders and the control group we found previously described polymorphisms in the P1 promoter of the IGF-1 gene (rs35767, rs5742612) and different genotypes. The frequency of both detected polymorphisms was no significantly different in the study and the control groups. The CA repeat sequence within the group of children in the study ranged from 11 to 21. The most common were homozygote 19/19 (49.02%) and heterozygote 19/20 (27.45%). Our results did not show any association between polymorphisms in the P1 promoter and IGF-1 levels in the serum of children with growth disorders. CONCLUSIONS This study demonstrated that SNP and (CA) n microsatellite repeat polymorphisms by themselves are not the primary regulatory elements of IGF-1 expression. However, our bioinformatics analysis has shown that the (CA) n microsatellite region in the P1 promoter of IGF-1 is able to form DNA loop structures which can modulate transcription.

Abstract
Human Papillomavirus (HPV) infection involves multiple steps, from cell attachment, through endocytic trafficking towards the trans-Golgi network, and, ultimately, the entry into the nucleus during mitosis. An essential viral protein in infectious entry is the minor capsid protein L2, which engages different components of the endocytic sorting machinery during this process. The ESCRT machinery is one such component that seems to play an important role in the early stages of infection. Here we have analysed the role of specific ESCRT components in HPV infection, and we find an essential role for VPS4. Loss of VPS4 blocks infection with multiple PV types, suggesting an evolutionarily conserved critical step in infectious entry. Intriguingly, both L1 and L2 can interact with VPS4, and appear to be in complex with VPS4 during the early stages of virus infection. By using cell lines stably expressing a dominant-negative mutant form of VPS4, we also show that loss of VPS4 ATPase activity results in a marked delay in capsid uncoating, resulting in a defect in the endocytic transport of incoming PsVs. These results demonstrate that the ESCRT machinery, and in particular VPS4, plays a critical role in the early stages of PV infection.

Abstract
In recent years, more scholarly attention has been paid to a growing range of geographic characteristics as antecedents of inequalities in women's health and well-being. The purpose of this study was to evaluate differences in health-related quality of life between rural and urban Polish postmenopausal women. Using a data set from a reproductive health preventive screening of 660 postmenopausal women aged 48-60 years, inhabitants of Wielkopolska and Lublin provinces, the association of place of residence, socioeconomic status and lifestyle factors with health-related quality of life (the SF-36 instrument) was evaluated using ANCOVA models and multiple logistic regression analysis with backward elimination steps. A consistent rural-to-urban gradient was found in all indices of physical health functioning and well-being but not in vitality, social functioning, emotional role and mental health scales with women in large cities being likely to enjoy the highest and those in villages the lowest quality of life. The rural-urban disparities in health-related quality of life were mediated by women's socioeconomic status. The likelihood of worse physical and mental functioning and well-being was 2-3 times greater for the low socioeconomic status rural women than their counterparts from more affluent urban areas. The educational attainment and employment status were the most powerful independent risk factors for health-related quality of life in both rural and urban women. Better understanding of the role of socioeconomic status that acts as a mediator in the association between area of residence and health-related quality of life may be useful in developing public health policies on health inequalities among women at midlife.

Abstract
BACKGROUND The exact route of human papillomavirus (HPV) and herpes simplex virus (HSV) transmission from a pregnant woman to her fetus has not been clearly established thus far. The data of many studies raise the possibility of intrauterine infection. In order to clarify our knowledge about virus vertical transmission in pregnant women, viral prevalence in amniotic fluid cannot. To the best of our knowledge, this is the first study on HPV DNA and HSV DNA detection in amniotic fluid in Poland. MATERIAL AND METHODS The study covered 138 samples of amniotic fluid from patients undergoing invasive prenatal diagnostic procedures (for medical indications) during the second trimester of gestation. The aim of the study was to assess the prevalence of HPV and HSV in the amniotic fluid samples obtained from asymptomatic women with intact amniotic membranes. To identify viral DNA of HPV and HSV in collected material, polymerase chain reaction (PCR) was performed. RESULTS We did not find HPV or HSV DNA in any of the examined specimens of amniotic fluid. CONCLUSION Our investigation did not confirm the prenatal transmission of HPV and HSV to the amniotic fluid.

Abstract
Many attempts have been made to define nature of viruses and to uncover their origin. Our aim within this work was to show that there are different perceptions of viruses and many concepts to explain their emergence: the virus-first concept (also called co-evolution), the escape and the reduction theories. Moreover, a relatively new concept of polyphyletic virus origin called “three RNA cells, three DNA viruses” proposed by Forterre is described herein. In this paper, not only is each thesis supported by a body of evidence but also counter-argued in the light of various findings to give more insightful considerations to the readers. As the origin of viruses and that of living cells are most probably interdependent, we decided to reveal ideas concerning nature of cellular last universal common ancestor (LUCA). Furthermore, we discuss monophyletic ancestry of cellular domains and their relationships at the molecular level of membrane lipids and replication strategies of these three types of cells. In this review, we also present the emergence of DNA viruses requiring an evolutionary transition from RNA to DNA and recently discovered giant DNA viruses possibly involved in eukaryogenesis. In the course of evolution viruses emerged many times. They have always played a key role through horizontal gene transfer in evolutionary events and in formation of the tree of life or netlike routes of evolution providing a great deal of genetic diversity. In our opinion, future findings are crucial to better understand past relations between viruses and cells and the origin of both.

Abstract
Recent data demonstrate that human papilloma virus (HPV) plays a role in pathologies other than ano-genital cancers, specifically head and neck malignancies, and non-cancerous conditions such as recurrent respiratory papillomatosis (RRP). High-risk HPV16 and 18, and low risk HPV6 and 11 play the main role in HPV-related pathologies. As more and more information about the role of HPV infection in non-cervical diseases is amassed, additional questions about whether prophylactic HPV vaccines will effectively prevent these conditions are raised. HPV vaccination programs for the cervical pathology are being implemented worldwide. In the United States, the US Food and Drug Administration (FDA) approved the quadrivalent HPV vaccine for girls in 2006 and for boys in 2011. These vaccination programs were aimed at the genital, HPV-related lesions, and there was not much recognition at that time of how HPV vaccination programs might affect oral HPV infection, which is a risk factor for the development of HPV-related head and neck cancers. Vaccination has proved to be a successful policy, and an extant recommendation is aimed at preventing HPV and associated cervical and other anogenital cancers with the routine use of HPV vaccines for males and females. However, HPV vaccines are presently not recommended for preventing oropharyngeal cancer (OPC), although they have been shown to be highly effective against the HPV strains that are most commonly found in the oropharynx. This review is aimed at presenting the evidence-based knowledge concerning HPV vaccination and highlighting the trials and strategies for vaccine administration in HPV-dependent head and neck pathologies.

Abstract
Infection with human papillomaviruses (HPV) requires the minor capsid component L2, which plays an essential role in directing appropriate endosomal trafficking. Previous studies have indicated an infection route involving multi-vesicular bodies (MVBs), and an essential element in their biogenesis is the ESCRT machinery. Here we show that the ESCRT component TSG101 is required for optimal infection with both HPV-16 and BPV-1, with loss of TSG101 resulting in a decrease in viral infection, whereas overexpressed TSG101 increases rates of infection. We find that L2 proteins from multiple PV types interact with TSG101 and show that this interaction contributes to an alteration in the subcellular distribution of L2. In addition, TSG101 can modulate the levels of L2 polyubiquitination. These results demonstrate that TSG101 plays an important part in infection with diverse PVs, and suggests that trafficking of HPV through the ESCRT machinery and MVBs is part of infectious virus entry.

Abstract
Our previous study demonstrated a decreased expression of tumor susceptibility gene 101 (TSG101) in cervical cancer cells. To identify the mechanism responsible for TSG101 downregulation during cervical cancer development, we analyzed the TSG101 promoter using cis-element cluster finder software. One of the transcription factors whose binding site was detected in the TSG101 promoter was late SV40 factor (LSF). The aim of this study was to analyze the TSG101 protein and LSF expression levels during cervical cancer development. Immunohistochemical analysis confirmed a previously observed decreased expression of TSG101, whereas quantitative polymerase chain reaction (qPCR) and immunohistochemistry analysis revealed high expression of LSF in cervical, precancer and cancer cells compared with human papillomavirus (HPV)-negative non-cancer samples. High expression of LSF in cervical cancer HPV-positive cells suggests that this protein may be important in the regulation of TSG101 expression, as well as in cervical carcinogenesis. The role of LSF as a mediator in cervical cancer development must be confirmed in future studies.

Abstract
The Bacillus phage phiAGATE is a novel myovirus isolated from the waters of Lake Góreckie (a eutrophic lake in western Poland). The bacteriophage infects Bacillus pumilus, a bacterium commonly observed in the mentioned reservoir. Analysis of the phiAGATE genome (149844 base pairs) resulted in 204 predicted protein-coding sequences (CDSs), of which 53 could be functionally annotated. Further investigation revealed that the bacteriophage is a member of a previously undescribed cluster of phages (for the purposes of this study we refer to it as "Bastille group") within the Spounavirinae subfamily. Here we demonstrate that these viruses constitute a distinct branch of the Spounavirinae phylogenetic tree, with limited similarity to phages from the Twortlikevirus and Spounalikevirus genera. The classification of phages from the Bastille group into any currently accepted genus proved extremely difficult, prompting concerns about the validity of the present taxonomic arrangement of the subfamily.

Abstract
Plant antimicrobial peptides (AMPs) are a component of barrier defense system of plants. They have been isolated from roots, seeds, flowers, stems, and leaves of a wide variety of species and have activities towards phytopathogens, as well as against bacteria pathogenic to humans. Thus, plant AMPs are considered as promising antibiotic compounds with important biotechnological applications. Plant AMPs are grouped into several families and share general features such as positive charge, the presence of disulfide bonds (which stabilize the structure), and the mechanism of action targeting outer membrane structures.

Abstract
Several physiological activities have been assigned to E-peptides derived from pre-pro-insulin-like growth factor (IGF1) processing; however, the whole range of the E-peptides' functions is still unknown. The objective of this study was to investigate human Eb peptide (hEb) in terms of its bioactivity, cellular localization, and intracellular trafficking using human cancer cells. Human Eb fused with red fluorescence protein (RFP) or green fluorescence protein (GFP) localizes strongly to nucleoli and to a lesser extent to nuclei of HeLa and U2-OS cells. Mutagenesis of hEb nucleolus localization sequence (NoLS) leads to its partial delocalization from nuclei and nucleoli to cytoplasm of transfected cells. Thus, NoLS is not sufficient for the hEb to be localized in nucleoli of the cells and a different mechanism may be involved in hEb targeting. A BrdU ELISA showed that the proliferation index of cells expressing hEb hybrid proteins increased up to 28%. For comparison, the same assay was performed using HeLa cells treated extracellularly with synthetic hEb. A significant increase in the proliferation index was observed (41-58% for concentrations ranging from 10-100 nM, respectively). Additionally, a cell migration assay was performed using stable U2-OS cell lines expressing hEb fused with RFP or RFP alone as a negative control. The migration index of hEb expressing cells was 38.3% greater. The increase in cell proliferation index and in motile properties of hEb expressing cells demonstrate that hEb is more than a pre-pro-IGF1b processing product, and has intrinsic activity of biological significance.

Abstract
The family of glycine-rich plant proteins (GRPs) is a large and complex group of proteins that share, as a common feature, the presence of glycine-rich domains arranged in (Gly)n-X repeats that are suggested to be involved in protein-protein interactions, RNA binding, and nucleolar targeting. These proteins are implicated in several independent physiological processes. Some are components of cell walls of many higher plants, while others are involved in molecular responses to environmental stress, and mediated by post-transcriptional regulatory mechanisms. The goals of this study are to identify the coding sequence of a novel glycine-rich RNA-binding protein from Chelidonium majus and to propose its structural model. DNA fragments obtained using degenerate PCR primers showed high sequence identities with glycine-rich RNA-binding protein coding sequences from different plant species. A 439-bp nucleotide sequence is identified coding for a novel polypeptide composed of 146 amino acids, designated as CmGRP1 (C. majus glycine-rich protein 1), with a calculated MW of 14,931 Da (NCBI GenBank accession no. HM173636). Using NCBI CDD and GeneSilico MetaServer, a single conserved domain, the RNA recognition motif (RRM), was detected in CmGRP1. The C-terminal region of CmGRP1 is a glycine-rich motif (GGGGxxGxGGGxxG), and it is predicted to be disordered. Based on a 1fxl crystal structure, a 3D model of CmGRP1 is proposed. CmGRP1 can be classified as a class IVa plant GRP, implicated to play a role in plant defense.

Abstract
INTRODUCTION Growth disorders in children are multifactor, complex processes with often unknown etiology. The insulin-like growth factor-I (IGF-I) is one of the proteins participating in the transfer of growth signals, which are responsible in certain cases for the etiology of a growth disorder. AIM OF THE STUDY The aim of the study was an analysis of the coding sequence of the extracellular and intracellular domains of IGF-IR responsible for ligand binding (IGF-I) and kinase activity in the DNA of children with growth disorders, who have normal or slightly decreased levels of plasma IGF-I. MATERIAL AND METHODS DNA isolated from the peripheral blood of 50 short-statured children was used as study material. DNA fragments of IGF-IR obtained as a result of PCR amplification were analyzed using single stranded conformation polymorphism (SSCP) and sequencing. RESULTS We did not observe any changes in the IGF-IR sequences, thus it can be excluded as a factor responsible for growth disorders. CONCLUSIONS IGF-I receptor sequence changes are not the cause of growth disorders in the study group of children. To find the cause of growth disorders in the study group other proteins from somatotropic axis and/or signaling pathways should be studied in the future.

Abstract
The role of the CCHCR1 (coiled-coil α-helical rod protein 1) protein in the cell is poorly understood. It is thought to be engaged in processes such as proliferation and differentiation of epithelial cells, tissue-specific gene transcription and steroidogenesis. It is supposed to participate in keratinocyte transformation. It has also been found that this protein interacts with the E2 protein of human papilloma virus type 16 (HPV16). The oncogenic HPV forms, such as HPV16, are known to be necessary but not sufficient agents in the development of cervical carcinoma. In the present study, the CCHCR1 gene coding sequence and its expression was analyzed in normal, precancerous and cervical cancer cells. Changes in the non-coding region were found in 20.3% of the examined probes from women with cervical cancer or precancerous lesions and in 16.67% of the control probes. Most of the detected changes were single nucleotide polymorphisms (SNPs). Changes in the coding region were found in 22.8% of the probes with cervical cancer and in 16.67% of the control probes and all of them were SNPs. The level of CCHCR1 transcripts was determined using the real-time PCR method and the highest gene expression was detected in the H-SIL group and slightly decreased in the cervical carcinoma cells, compared with the control probes. It suggests that CCHCR1 could have a role in the process of cervical epithelial cell transformation, but this suggestion must be confirmed experimentally.

Abstract
BACKGROUND AND AIM The aim of this study was to test whether there was an association between systemic levels of insulin like growth factor-1 (IGF-1), IGF-1 binding protein-3 (IGFBP3) and selected parameters of lipid metabolism depending on the lipid-lowering therapy. This work was conducted in patients described by us previously who had either highly probable, or documented, coronary artery disease, and controlled serum lipids with prolonged statin therapy. METHODS The study was conducted among 140 patients undergoing coronary angiography. The following parameters were measured: LDL- and HDL-cholesterol levels, TG, TC, apoB-100, apoA1, Lp(a) and IGF-1 and IGFBP3, as well as the level of oxidation products of proteins and lipids. RESULTS AND CONCLUSIONS In the group of patients with LDL target up to 100 mg/dl and statins use, as well as in the entire population, IGF-1 and IGFBP3 were associated with protein oxidation products and Lp(a). Additionally, in the whole studied group, IGF-1 was associated with TG and LDL. More differences were observed when we used multivariate analysis. Even then, IGF-1 and IGFBP3 in the group with LDL up to 100 mg/dL, as well as in the entire group, were associated with protein oxidation products, Lp(a) and with quantitative arteriosclerosis scale (Gensini score). These results seem to confirm our previous findings, wherein significantly higher levels of systemic IGF-1 were found in patients with advanced coronary atherosclerosis.

Abstract
OBJECTIVE To compare the prevalence of human papillomavirus (HPV) in placentas from women with spontaneous abortions and from control women after term delivery. DESIGN Cross-sectional study. SETTING Department of Obstetrics and Pathology of Pregnancy, Medical University of Lublin (Poland). POPULATION Patients whose spontaneous abortions occurred between the 6th and the 16th week of pregnancy (n=51), and women after term delivery (n=78). METHOD Polymerase chain reaction (PCR). MAIN OUTCOME MEASURES HPV DNA prevalence rate and the fraction of HPV 16/18 infections in aborted products of conception and placentas. RESULTS Patients with spontaneous abortion did not differ from the controls in terms of mean age and the fraction of primiparas. The DNA of HPV was detected in 17.7% of aborted products of conception and in 24.4% of placentas from term deliveries. The aborted products of conception and full-term placentas were positive for HPV 16/18 in 11.8 and 12.8% cases, respectively. Patients whose material was positive for HPV DNA or those with confirmed HPV 16/18 did not differ significantly from HPV-negative women in terms of mean age and the fraction of primiparas. CONCLUSIONS The HPV 16/18 infection rate does not seem be higher in cases of spontaneous abortions. Nevertheless, further study of the consequences of HPV infection in pregnancy is still needed.

Abstract
UNLABELLED Human papillomaviruses (HPVs) are a very complex group of pathogenic viruses, with more than 80 types, causing human infection. Given the prevalence of HPV infection and its relationship with the development of cervical and many other cancers, HPV vaccine development has been a major public health initiative worldwide in the last decade. The aim of the presented study was to identify HPV DNA by MY-PCR in 4,150 school children and adolescents, aged 10-18 years in the Wielkopolska region, Poland. All individuals were asked to fill in extensive questionnaires; further normal, oral squamous cells were collected from each pupil. Cellular DNA was isolated and used as a MY-PCR template to estimate the incidence of HPV-active infection. Forty five subjects (1.08% of the sample) were carriers of oropharyngeal HPVs. HPV status and variables of interest, such as age, gender, socioeconomical status, and risk factors (smoking and sexual intercourse history, alcohol consumption) were not correlated. The presence of HPVs in the oral cavity was cumulated in several schools of the region. DNA sequencing of MY-PCR products revealed only four HPV genotypes. The most frequent genotype was HPV11 (38/45 HPV-positive cases), while other more rare genotypes were HPV6 (3/45), HPV12 (3/45), and HPV57 (1/45). CONCLUSION Our findings presented herein, reveal a relatively low prevalance of oropharyngeal HPVs in Polish adolescents and fill an important gap in the knowledge of oral HPV infections of children above 10 years and adolescents.

Abstract
Human papillomaviruses (HPV16, HPV18, HPV31, HPV33) are etiological agents in the development of cervical cancer. HPVs infect epithelial cells and depend on epithelial differentiation for the completion of their life cycle. Insulin-like growth factor I (IGF-I) is a potent mitogen involved in the regulation of cell proliferation and apoptosis of many cell types including normal and transformed epithelial cells. Deregulation of IGF-I expression and action is linked to diverse pathologies including cancer. A polymorphism in the P1 promoter region of the IGF-I gene may directly influence its expression. Using the PCR-SSCP method and sequencing of DNA, we identified a single nucleotide polymorphism (SNP) at -383(C>T) position of promoter P1 of the IGF-I in 16% of the study HPV-positive women with precancerous and cancerous lesions. In vitro, we observed that the SNP at-383(C>T) site significantly increased the reporter gene expresion in the HepG2 cell line, but not in the HeLa cell line relative to the wild type promoter. It suggests that the studied SNP can change expression of the IGF-I gene in distinct ways in different types of tissues. Deregulation of expression of the IGF-I gene can affect normal epithelium development and in case of HPV infection can potentially disrupt the virus life cycle and stimulate its passage into the oncogenic life cycle or persistent viral infections. Therefore, we propose that SNP C>T at the -383 position of P1 promoter may be one of the helpful prognostic markers in the diagnosis of cervical cancer development of women with persistent infection in the ectocervical epithelium. We have not found any association between the polymorphism CA repeats in the promoter P1 region of the IGF-I gene and suceptibility to HPV infection and cervical cancer development. The (CA)19 allele was the most common in the study of this group of women.

Abstract
All-trans retinoic acid (ATRA) is considered to be a potential chemotherapeutic drug due to its capability to regulate cell growth and differentiation. The effects of ATRA on the proliferation of cells and gene regulation are mediated by retinoid receptors (RAR and RXR), which belong to the nuclear receptor superfamily of ligand- inducible transcription factors. ATRA can act either as a growth inhibitor or growth promoter, according to the functional state of retinoic receptors. Thus, we have established the effect of ATRA on the proliferation of cervical cancer cells line HeLa and CaSki and expression of retinoids receptors as well as the viral HPV oncogenic proteins E6 and E7. ATRA had no effect on proliferation CaSki cells, but it stimulated the growth of HeLa cells, which depended on the incubation time and the concentration of ATRA in cell culture. The overexpression of RAR alpha in HeLa cells after the administration of 10(-7) mM ATRA was also observed 72 hours, and the decrease of CaSki by 60-90%. In the study of cervical cancer cell lines, the very low levels of other endogenous RAR and RXR receptors were observed. ATRA does not repress the expression of two viral oncoproteins E6 and E7 HPV16/18, which play a key role in carcinogenesis of the cervix. Our results support the suggestions that the cell response to vitamin A, and other retinoids in the diet, may depend on cell type, and that the cancer cells are differentially resistant to retinoids. Thus, despite the important biological functions of retinoids, the effects of retinoids in a supplementation in supra-physiological doses as well as their physiological action are difficult to define.

Abstract
UNLABELLED The aim of the present study was to determine the prevalence of Leptotrichia amnionii in cervical swabs of women and its possible correlation with HPV infection and the stage of cervical cancer. MATERIAL AND METHODS A total of 139 cervical swabs from healthy women with normal cytology, with dysplastic changes and with cervical cancer were tested for the presence of L.amnionii and high-risk HPV DNA by PCR methods. RESULTS L. amnionii was found in normal vaginal flora and in women with bacterial vaginosis (BV), which suggests that it may be oportunistic pathogen. L. amnionii infection was diagnosed in 13.7% (19/139). Statistical analysis showed that there was positive association (p < 0.01) between the presence of L.amnionii in women with cervical cancer (38.5%) and its presence in women without cancer (11.1%). On the other hand, there was no statistically significant association between L.amnionii and HPV infections. CONCLUSION The data presented in this study show for the first time the prevalence of L. amnionii infection in cervical specimens collected from 2004-2006 in Poznan and Lublin, Poland, and its association with HPV infection and the stage of carcinogenesis of the cervix.

Abstract
PURPOSE The aim of the study was to evaluate the frequency of occurrence of HPV and co-infection: Chlamydia (C.) trachomatis and HSV-2 in cervical cancer. MATERIAL AND METHODS The study group consisted of 570 paraffin-sectioned samples of patients with cervical cancer. In order to identify viral and bacterial DNA in DNA isolated from archival, postoperative material, PCR analysis was performed using starters complementary to various types of HPV, HSV-2 and C. trachomatis. RESULTS In patients with squamous cell cervical cancer the presence of 33 types of HPV was found in 90% (468/520). HPV 16 infections occurred in 69.4% (325/468), while HPV 18 infections were present in 30.5% (143/468) of cases. In the control group C. trachomatis and HSV-2 were observed in four cases (4/50), which constitute 8.0%. In the tissue sections from patients with squamous cell cervical carcinoma, C. trachomatis was identified in 26% (135/520) and HSV-2 in 28% (145/520). In the group of patients with adenocarcinoma C. trachomatis infections were found in 24% (12/50) and herpes virus was identified in 30% (15/50). Statistically significantly higher frequency of occurrence of HSV-2 and C. trachomatis was observed in paraffin-sectioned samples for patients with invasive cervical cancer compared to the control group, without neoplastic lesions (p < 0.05). No correlation was found between frequency of occurrence of HPV and C. trachomatis and of HPV and HSV-2 detected in paraffin-sectioned samples for cervical carcinoma.

Abstract
AIMS The purpose of the study is to estimate whether the cognitive, functioning and emotional impairments in patients with Alzheimer's disease are related to lifestyle behaviours in the stage of life prior to the diagnosis of the disease. METHODS Altogether, 65 patients with Alzheimer's disease, 55 women and 10 men, participants of the day center, run by the Wielkopolska Association of Alzheimer's Disease and residents of the Senior Nursing Home in Koprzywnica, were examined. Cognitive, functioning and emotional impairments of patients as well as lifestyle behaviours in the stage of life prior to the diagnosis of AD were estimated using AD-specific questionnaire, which were completed by caregivers. Qantitative and qualitative analyses were run using appropriate statistical procedures available in the Statistica 7.1 programme [StatSoft. Inc.2005 Statistica for Windows]. RESULTS The findings revealed that patients with AD aged 70 years and older were likely to be more frequently impaired with daily life functioning than their younger counterparts. Patients with a higher attainment of education were more frequently impaired with cognitive than emotional problems and depression. Of all the variables in question, calendar age, educational attainment and intellectual activity in the stage of life prior to the diagnosis of disease were most significant in explaining the variation in the current impairments. Persons who were younger and intellectually active prior to the disease, were likely to be suffering less from the burden of AD than the older and less intellectually active counterparts. CONCLUSIONS The association between educational attainment and intellectual activity in the stage of life prior to the occurrence of AD, and the burden of AD, found in the study, indicates that a lifelong intellectual activity may help to reduce disabilities and improve the patients' quality of life.

INTRODUCTION Human Papilloma Virus has a strong relation to oropharyngeal mucosa and is considered to be responsible for a wide range of upper respiratory tract pathologies, like laryngeal papilloma. There's a hypothesis, that it plays a significant role in middle ear chronic inflammations and neoplasm's. MATERIAL AND METHODIC. The examination was carried on a group of 53 patients, 39 of which was suffering from granulation tissue chronic otitis media, 7-cholesteatomatous otitis media, 6--middle ear malignant neoplasm, and 1 middle and/or external ear benign neoplasm. The control group consisted of 5 patients operated on: otosclerosis--4 cases and post-traumatic tympanic membrane perforation--1 case. The material was postoperative tissue, like polyps, inflammatory granulation tissue, cholesteatoma masses and malignant neoplasm's tissue. RESULTS In the whole group of 53 examined cases, HPV DNA was confirmed in 22 cases (41.5%), in that group oncogenic types 16 or 18 in 12 cases (22.6%), and in 14 cases (26.4%) types 6 or 11. In a group of chronic granulomatous otitis media DNA characteristic for Papilloma was identified in 12 cases (25.6%), in it in 9 cases DNA HPV type 6 or 11 was confirmed, and in 7 cases type 16 or 18. Among cholesteatomatous chronic otitis media HPV DNA types 6 or 11 was identified in 70%. In every case of middle ear malignant neoplasm a presence of high-risk DNA Papilloma types 16 or 18 was confirmed. In any case of control group HPV DNA was detected. CONCLUSIONS The results has been compared with other authors examinations and it is claimed that they confirm the observation, that Human Papilloma Viruses may be a factor, that might play an important role in pathology of chronic otitis media and ear neoplasm's. It is concluded, that differences in percentages of HPV presence in chronic inflammations (70%) and ear neoplasm's may be explained by viral co-infection during bacterial c. o. m. Viral infection probably evolves carcinogenesis, which leads to a neoplastic growth.

Abstract
The human papillomavirus family is composed of a large number of different and variably related types, each of which is associated with a characteristic set of epithelial lesions. Each of the many identified types of human papillomavirus have shown considerable specificity of different anatomical sites and different characteristic lesions. HPV 6 and 11 are frequently associated with benign condylomas, while HPV 16 and 18 are associated with malignant progression and cervical cancer. The genome of papillomaviruses is composed of a circular double stranded DNA. Various open reading frames (ORFs) are located on only one DNA strand. The coding strand contains from 8 to 10 translational ORFs. Among them, only 6 to 8 were designated as early and 2 as late. The role of HPVs 16 and 18 in uterine cervix carcinoma has been well-documented, but their contriobution to carcinogenesis of other neoplasias is still questionable.

Abstract
Human papillomaviruses infect epithelia but little is known about the nature of cell surface receptors interacting with the viral particles. It has been proposed that glycosaminoglycans and integrins may be involved in the attachment process. In the present study, the putative interactions of virus-like particles of human papillomavirus type 11 (HPV11), which present a tropism for nasopharyngeal epithelia, with olfactory and taste receptors expressed in the human lingual epithelium were studied. The L1 protein of HPV11 was produced in insect cells. The presence of L1 virus-like particles was analyzed by ELISA using monoclonal antibodies specific for full-size particles and by electron microscopy. Using immunofluorescence, it was observed that virus-like particles interacted with taste buds from murine tongue, with the tagged human olfactory receptor hJCG5 expressed in HEK-293 but not with the tagged taste receptor hT2R4. This therefore suggests that hJCG5 may be involved in the adsorption process of HPV11 to lingual epithelium serving as a so-called "adsorption-adhesive molecule."

Abstract
Ghrelin is one of the peptides involved into GH-release, binding to specific GHS receptors on hypothalamus and pituitary. The ghrelin peptide and ghrelin mRNA have been detected in several regions of hypothalamus, in normal pituitary, as well as in various types of pituitary adenoma, with different levels of expression in different tumour types. We decided to determine the expression of ghrelin in somatotroph adenomas. Human pituitary somatotroph adenoma tissues were obtained at the time of transsphenoidal surgery from 3 acromegalic patients and studied for ghrelin mRNA expression. Before surgery each patient received a somatostatin analogue treatment at doses 20 mg, 30 mg, 30 mg at 30 days intervals. 20 mg of each tissue sample was used for the isolation of total cellular RNA. The reverse transcription and real-time PCR were performed according to Korbonits et al. method. The reverse transcription of total RNA to cDNA was performed using Super Script TM Rnase H RT kit according to manufacturer protocol. We wished to determine the number of copies of ghrelin gene within the single cell. We used the beta-actin, and the GAPDH genes as a reference molecules for standard curve calculation. Ghrelin mRNA was not detected in any examined tissues. We postulate that the absence of the ghrelin gene transcript is mainly due to the treatment with somatostatin analogues administered preoperatively, which could have suppressed the ghrelin gene transcription.

Abstract
UNLABELLED The aim of this study was to estimate of the role of chronic HPV 16 infection and the presence of anti E6 HPV 16 in the initiation of the cancerogenesis process of cervical cancer. MATERIAL AND METHODS The study included two groups of patients. The first group comprised 323 women observed for three consecutive years (1998-2000), in whom the presence of HPV 16 viruses was estimated by PCR, and the level of anti E6 HPV 16 antibodies was estimated in the plasma with ELISA. A similar test was performed in a group of 46 patients with cervical intraepithelial neoplasia (CIN), 91 patients with invasive cervical cancer and 22 women after hysterectomy and RTG-therapy. RESULTS In 32 patients, chronic HPV 16 infection showed a steady rise in the mean absorbance level of anti E6 HPV 16 antibodies from 0.04 in 1998 to 0.06 in 2000, while in HPV-negative women the mean absorbance value was 0.03-0.04. Mean absorbance value in patients with CIN III and invasive cancer rose with advancing stage of the cancer process and lowered after completion of oncological treatment. The values were 0.14, 0.33 and 0.13, respectively. CONCLUSION The persistence of chronic HPV 16 infection and accompanying steady rise in absorbance index caused by an increase in the level of antiviral antibodies are a clear warning signal preceding in time the histological process of cancerogenesis.

Abstract
The human NR4A1 orphan receptor is a member of the TR3 steroid receptor superfamily, which binds DNA at the NBRE and NurRE responsive elements. The TR3 receptors are involved in the regulation of differentiation, proliferation and apoptosis. We report that NR4A1 interacts with human papillomavirus type 16 (HPV16) E2 protein--a key papillomavirus regulatory factor. This interaction might be involved in the transcription regulation of the HPV16 genes and the regulation of infected cell homeostasis.

Abstract
BACKGROUND The role of viral and bacterial co-infection is stressed in VIN. A view that VIN is a sexually transmitted disease made the area of research larger and stimulated scientists to seek other sexually transmitted factors, among which Chlamydia trachomatis and Herpes simplex are frequently examined. PURPOSE The aim of the study was to evaluate the frequency of occurrence of HPV DNA and the frequency of co-infection with Herpes virus type 2 and Chlamydia trachomatis in VIN. MATERIAL AND METHODS We identified archival diagnostic phase tissue specimens from 41 cases of vulvar intraepithelial neoplasia III. From the same paraffin blocks containing material from the margins of surgical sections during vulvectomy, normal epithelial tissue fragments were collected. They constituted the control group. Lesion characteristics were examined in comparison with the presence of HPV DNA, HSV-2 and Chlamydia trachomatsis. Identification was performed using PCR. RESULTS In the study group HPV infection was found in 75.6% of cases. In 73% of cases it was HPV 16. In the control group we found HPV 16 DNA in only one case (2.43%). In the HPV positive study group HPV 16 was found in 30 (30/31) cases. In only one case (1/31) it was HPV 18 type. In the study group of 41 cases with VIN, HSV-2 infection was found in six cases (14.63%). In comparison with the control group (9.75%) the difference was not statistically significant. The frequency of occurrence of Chlamydia trachomatis in the analyzed study material was 14.63% (6/41) and in the control group it was 9.75% (4/41). The difference was not statistically significant. Statistical analyses of correlations between the occurrence of DNA HPV and HSV-2 as well as of HPV and Chlamydia trachomatis showed no correlation in either case. CONCLUSION No correlation was found between the frequency of occurrence of HPV and HSV-2 and HPV and Chlamydia trachomatis in either group.

Abstract
Human papillomavirus (HPV) infection is a major risk factor for the development of cervical cancer. The HPV-induced immortalization of epithelial cell usually requires integration of the viral DNA into the host cell genome. The integration event causes disruption of the E2 gene and this is followed by overexpression of the E6 and E7 oncoproteins. The E2 protein is a transcription factor that regulates expression of the E6 and E7 oncoproteins by binding to four sites within the viral long control region. We used an in vitro cell culture model to explore the role of the E2 protein in the transcriptional control of the HPV16 long control region. Employing transient and stable transfection experiments we simulated the episomal and integrated states of the viral genome, respectively. We show that the E2 protein up-regulates E6/E7 transcription from episomal DNA but represses it in the case of integrated DNA. The activator function of the E2 protein seems to counteract the repressive chromatin structure formed over episomal DNA. Steroid hormones and retinol also modulate oncogene transcription differently depending on the physical structure of the viral DNA. Our data suggest regulatory mechanisms involving interactions between the E2 protein and nuclear hormone receptors.

Abstract
Olfactory and pheromone receptors (ORs) constitute a large family of G-protein-coupled receptors involved in the detection and transduction of odorant signals. Using degenerated primers complementary to the highly conserved transmembrane domains II, III, VI, and VII within this protein family, Gaudin et al. have recently described the expression of several OR genes in foetal human tongue. Among the nine genes identified in human foetal tongue (HTPCR06, HGMP07I, JCG6, TPCR85, JCGI1, JCG2, JCG3, JCG5, and JCG9), only four (HTPCR06, HGMP07I, JCG3, and JCG5) were found to be expressed in adult tongue, suggesting that ORs might perform developmental functions in this organ. The objective of our work was to obtain additional information about the expression of olfactory-like genes in human tongue. In the present study, the synthesis and the screening of a cDNA library from epithelial cells of human adult tongue is reported. Two kinds of PCR analysis were performed. First, partial olfactory-like receptor cDNAs amplified with the degenerated primers used by Gaudin et al. were cloned and described. Second, a comparison of the expression profiles of the olfactory-like receptor genes previously identified before was carried out using specific primers. Among the genes studied we found that four genes (HTPCR06, JCG3, JCG5, and JCG6) are expressed in epithelial cells of the surface of the adult tongue. Additionally, we show that three olfactory-like receptor genes OR7A5/HTPCR2, OR6Q1, and OR7C1/TPCR86 are also expressed in these cells.

Abstract
OBJECTIVES Cervical cancer in Poland is second most common type of cancer, after breast cancer. There are known risk factors of cervical cancer development and the most serious one is human papilloma virus infection (HPV). DESIGN The aim of our paper is present the result study 414 cervical cancer of women from Wielkopolska region treated at the Department of Gynecology and Obstetrics, Karol Marcinkowski University of Medical Sciences in Poznań. MATERIALS AND METHODS In morphological study grading, staging and vascular invasion were estimated. In cervical cancer tissue papillomaviruses PCR method were used. In immunohistochemical study, expression of proteins checking the cell cycle, share in signal transduction to nucleus, cell receptors for steroid hormones and viruses oncogenic proteins were investigated. In the part of cancer gene mutation of p53 (60 cancers) i k-RAS (40 cancers) were searched. RESULTS In cancers HPV 16/18 infected vascular invasion were more frequently (p < 0.013). No statistically significant difference in cellular proteins expression in the HPV16/18 positive cancers, HPV16/18 negative and cancers without HPV was observed. However significant difference were demonstrated in proteins expression depending from degree of cancer stage. CONCLUSIONS The result of these studies suggest that super expression for EGFr is poor prognostic factor in the early stage of cancers (I-II0).
