Estrogen is a steroid hormone that plays an important role during sperm development in the male and female reproductive tract. Estrogen signalling is a complex process that depends on cell milieu and presence of receptors. Thanks to the steroid nature of estrogens, they can pass through the plasmatic membrane and bind to the intracellular estrogen receptors (ERs). Within the cell, there are several pools of ERs. One of them is localized to the cell nucleus and their activation leads to direct or indirect binding to DNA and ultimately to alternation in gene expression (genomic pathway). Other pools of ERs are associated with plasma membrane or are located in cytosol. Activation of membrane associated ERs leads to rapid non-genomic responses. Nowadays, two classical estrogen receptors are known – ERα and ERβ. Since ERβ is a predominant variant in testes, we focused our study on expression of ERβ variants in murine testes and sperm. We detected two variants of ERβ at mRNA level in both, testes and sperm. These variants differ in 54 nucleotids within the ligand binding domain and this variability results in different affinity to estrogen. We analyzed individual testicular cell types (spermatogonia, spermatocytes, spermatids, Sertoli cells) by RT-qPCR. Our results suggest that both ERβ variants are coexpressed in the same cell type and may therefore interact together. This may have consequences in mediating of estrogen signalling. Moreover, ERβ is expressed more in the later stages of spermatogenesis suggesting the role of ERβ in these stages or alternatively in spermatozoa alone. At the protein level, we detected ERβ in nuclear, membrane and cytosolic fraction prepared from testicular tissue suggesting the involvement of both, genomic and non-genomic, pathways of estrogen signaling in testes. In sperm, anti-ERβ antibodies localized ERβ in acrosome region and tail which is in accordance with the known role of estrogen on capacitation, acrosome reaction and motility.

Possible role of spermatogenic protein glyceraldehyde-3-phosphate dehydrogenase (GAPDHS) in mammalian sperm
Margaryan, Hasmik ; Dorosh, Andriy ; Čapková, Jana ; Postlerová, Pavla ; Philimonenko, Anatoly ; Hozák, Pavel ; Pěknicová, Jana
Sperm proteins are important for the structure and function of these specific, highly differentiated cells. Certain of these proteins play a role in sperm-egg recognition during primary or secondary binding at zona pellucida glycoprotein matrix. The aim of this study was to characterize the acrosomal sperm protein recognized by a monoclonal antibody (MoAb) Hs-8, prepared in our laboratory by immunization of BALB/c mice with human ejaculated sperm, and to test the possible role of this protein in gamete interaction. MoAb Hs-8 specifically labelled a 45 kDa protein from the sperm extract in the immunoblotting test. Sequence analysis identified this Hs-8 protein as GAPDHS. In order to perform a control tests, a commercial mouse anti-GAPDHS MoAb was applied. Both antibodies showed similar staining patterns using immunofluorescence labelling, transmission electron microscopy and immunoblot analysis. Moreover, both Hs-8 and commercial anti-GAPDHS antibodies blocked the secondary sperm-zona pellucida binding. Generally, GAPDHS was considered mainly as sperm-specific glycolytic enzyme involved in energy production during spermatogenesis and sperm motility and its role in the sperm head was unknown. In this study, we confirmed the potential additional role of GAPDHS as a binding protein that is involved in the sperm-zona pellucida interaction.

Fluorescent analysis of the differential protein expression in normozoospermic and asthenozoospermic sperm samples
Děd, Lukáš ; Čapková, Jana ; Kubátová, Alena ; Teplá, O. ; Pěknicová, Jana
Asthenozoospermia is one of the main seminal pathologies underlying male infertility. Previous proteomic studies have demonstrated the significant differences in the protein profiles between normozoospermic and asthenozoospermic sperm samples. Since these studies were primarily focused on the identification of differentially expressed proteins by mass spectrometry, we aimed to evaluate the ability of our diagnostic antibodies to detect the differential expression of selected protein markers by fluorescent microscopy and flow cytometry techniques. Therefore, we analyzed sperm samples from 30 men with normal and 30 men with astheno spermiograms, average by the panel of our diagnostic anti-human sperm (Hs) antibodies. Fluorescent microscopy and flow cytometry analysis revealed quantitative differences in the protein abundances between normo and astheno sperm samples, namely, in GAPDHs, evaluated with Hs-8 MoAb, VCP, evaluated with Hs-14 MoAb, and ATP synthase, evaluated with MoAb Hs-36. From the methodological point of view, we observed very high correlation between the data obtained by fluorescent microscopy and flow cytometry techniques and therefore both methods are useful for evaluation of protein differences associated with asthenozoospermia. From the clinical point of view, we observed the strong association of the low sperm motility in the sample with the expression of proteins, playing an important role in sperm energy metabolism (expected), but also with the expression of all tested intra-acrosomal proteins. These findings further demonstrate asthenozoospermia as a complex semen disorder frequently associated with other semen pathologies, which are not diagnosed by basic semen analysis, and the possibility to use monoclonal antibodies as a tool for diagnosis of protein associated sperm pathologies in the semen with the low sperm motility.

The role of a nurse in a prevention and a treatment of intestinal parasites of children
JANDOVÁ, Anna
The best-known intestinal parasites are Pinworms, Roundworms, Tapeworms and the disease called Toxocarosis. The oftenest parasite is, according to sources, the Pinworm. Intestinal parasites affect mostly young children of pre-school age, sometimes even older. The first goal of the thesis was to investigate parents' awareness of the prevention of parasitic diseases in children. There is a hypothesis set to this goal: Parents of children who suffered from parasitic disease are more informed than parents of children who have not had this disease. The second goal was to map the specifics of nursing care for children with parasitic diseases at GPCHA practice. A research question was chosen for this aim: What are the specifics of nursing care at GPCHA in parasitic diseases? In methodology, the empirical part was chosen and it was a qualitative - quantitative research survey. For the quantitative part, the interrogation method and technique of non-standardized questionnaire was used. The research sample of quantitative survey consisted of 223 respondents, it means parents whose child is aged from 0 to 6 years. The questionnaires were distributed on social networking and others in a nursery school in Týn nad Vltavou. At the very beginning, respondents were acquainted with the topic of the thesis. The results of a quantitative survey were processed with the help of a data matrix and were further processed within twenty-arranged bar charts. To verify the hypothesis, we used the Chi- Quadrat test, which in this case is not satisfactory, therefore, there had to be chosen to merge the responses. An interrogation method, technique-depth interview was used in the qualitative part. The research group consisted of five nurses; three nurses working at GPCHA in Týn nad Vltavou and two working at GPCHA in České Budějovice. While processing the interviews, there open coding was used and an analysis of interviews was conducted by using the method of Pencil and Paper Interview. The results of this bachelor thesis will be published in the journal Paediatrics practice.
