Project title: Intestinal barrier dysfunction and epithelial-immune cell interactions in plectinopathy
Supervisor: Martin Gregor (martin.gregor@img.cas.cz)
Co-supervisor: Alžběta Kalendová (alzbeta.kalendova@img.cas.cz)

Project description: Inflammatory bowel disease (IBD) is characterized by compromised intestinal barrier function in association with excessive activation of the mucosal immune system. Using mouse model of plectinopathy we show that absence of plectin, a highly versatile cytolinker, in intestinal epithelium aggravates experimentally induced colitis and potentiates associated carcinogenesis. The major goal of this project is detailed analysis of molecular mechanism underlying governing role of plectin in intestinal barrier maintenance. In addition, we will study the impact of plectin deficiency on initiation and progression of colorectal cancer. We will further develop mouse model with tissue-specific plectin ablation in myeloid cell lineage and characterize it with respect to plectin-controlled epithelial-immune cell interactions. Understanding the mechanisms involved in the plectin-deficiency-mediated pathogenesis of IBD and colorectal cancer is necessary to define new targets for disease screening and strategies for its prevention and treatment. The successful candidates will learn and utilize advanced cellbiology, molecular-biology, physiology and imaging techniques, while developing and analyzing various mouse models.

Laboratory of Cellular and Viral Genetics http://www.img.cas.cz/research/jiri-hejnar/

Project title: Functional characterization of avian sarcoma and leukosis virus receptors
Supervisor: Daniel Elleder (elleder@img.cas.cz)

Topic: Avian sarcoma and leukosis virus (ASLV) served historically as a key model in both virus and cancer research. Our laboratory has long tradition with this model. More recently, we have identified and further characterized some of the cellular receptor molecules employed by the virus for entry into host cells. The current project will aim at elucidating the function that these receptor molecules play in the biology of the chicken cell, and how it impacts the cytopathic effects of the virus infection. The work will be mostly using molecular biology and virology techniques, but will also involve bioinformatic methods (their prior knowledge is not required). We will try to identify selection pressures exerted during avian evolution on the receptor molecules. We will also try to identify endogenous receptor ligands. Lastly, we will try to identify how new virus subgroups are formed by recombination with chicken endogenous retroviruses. Further reading: 1. J Virol, 2005, 79:10408; 2. J Virol, 2004, 78:13489; 3.

Laboratory of Biology of the Cell Nucleus http://www.img.cas.cz/research/pavel-hozak/

Project 1

Project title: Contribution of (pre)lamin A – phosphoinositides complexes to intranuclear order
Supervisor: Pavel Hozák (pavel.hozak@img.cas.cz)

Project description: Lamins are intermediate filament proteins present in nuclear lamina and, to less extent, in the nuclear interior. They are involved in a variety of nuclear functions, such as regulation of gene expression, DNA replication, DNA repair, chromatin organization, and cellular ignalling. Mutations in lamins cause severe disease – laminopathies. While interactions and functions of lamins in lamina are extensively addressed, much less is known, about the lamin pool in the nuclear interior. Our preliminary data demonstrate that lamin A forms a complex with nuclear myosin I and a phosphoinositide phosphatidylinositol 4,5-bisphosphate. This project focuses on detailed characterization of these complexes by biochemical, structural and advanced microscopy methods using various experimental models. The project will implement molecular biology and biochemistry methods as well as the state-of-the-art imaging techniques including fluorescence, confocal and super-resolution (SIM, STED, STORM) microscopy. The project is supported by recently awarded funding from the Grant Agency of the Czech Republic.

Candidate profile: M.Sc. (Mgr.) degree or equivalent in molecular/cellular biology or biochemistry, good English, independent thinking, strong interest in basic research and experimental work, dedication to learn and develop new techniques.

 

Project 2

Project title: Phosphoinositides compartments in the cell nucleus – their structure and functions
Supervisor: Pavel Hozák (pavel.hozak@img.cas.cz)

Project description: Phosphoinositides are phosphorylated species of phosphatidylinositol. They are present at all membranous structures within a cell (plasma membrane, ER, GA, endosomes and various vesicles) where they direct membrane trafficking and serve as signalling molecules. Surprisingly, phosphoinositides localize also to the cell nucleus, which is internally absent of membrane. We have previously demonstrated that phosphatidyl inositol-4,5-bisphosphate (PIP2) is present in the nucleolus as well as carbon-rich patches which we termed the lipid islets. We have shown that nucleolar PIP2 stimulates activity of RNA polymerase I and other transcription factors such as UBF and fibrillarin and thus modulates transcription of rDNA genes. In the nucleoplasm, lipid islets associate with RNA polymerase II and their absence negatively affects transcription of proteincoding genes. The exact mechanism, however, remains largely unknown. This project focuses on finding (i) the detailed composition of lipid islets as well as (ii) defining a cross-talk between various phosphoinositides within the nucleus, (iii) defining direct protein interacting partners of phosphoinositides, and (iv) elucidating the mechanism by which the phosphoinositides modify nuclear processes, e. g. RNA polymerase II transcription.

The PhD project will implement molecular biology and biochemistry methods as well as the state-ofthe-art imaging techniques including fluorescence, confocal and super-resolution (SIM, STED) microscopy. The project is supported by funding from the Grant Agency of the Czech Republic.

Candidate profile: M.Sc. (Mgr.) degree or equivalent in molecular/cellular biology or biochemistry, good English, independent thinking, strong interest in basic research and experimental work, dedication to learn and develop new techniques.

 

Project 3

Project title: Identifying the interactions of chromatin and the nuclear periphery
Supervisor: Jindřiška Fišerová (jindriska.fiserova@img.cas.cz)
Co-supervisor: Pavel Hozák (hozak@img.cas.cz)

A nuclear periphery involves a nuclear envelope with a lamina tightly attached to the inner nuclear membrane and nuclear pore complexes facilitating nucleocytoplasmic transport. The nuclear periphery plays a crucial role in chromatin organisation, regulation of gene transcription, gene silencing or in mediating the communication between the nucleus and the cytoplasm. The importance of the nuclear periphery is also demonstrated by number of diseases (called envelopathies) resulting from a mutation in genes encoding for one of the peripheral protein such as lamin or emerin. The structure of the nuclear periphery as well as the role of proteins associated with the periphery in the above mentioned processes is fragmentary. This project focuses on those topics and aims to further uncover the biochemical interactions at the nuclear periphery. The PhD project will implement the state-of-the-art imaging techniques including super-resolution (SIM, STED) as well as molecular biology and biochemistry methods for in-depth studies of the role of periphery associated proteins in chromatin organisation.

Candidate’s profile (requirements): M.Sc. (Mgr.) degree or equivalent in molecular/cellular biology, good English, independent thinking, strong interest in basic research and experimental work.

Laboratory of Transgenic Models of Diseases http://www.img.cas.cz/research/radislav-sedlacek/

Project 1

Project title: Elucidation of the biological role of Tiki, Wnt-specific Metalloproteases
Supervisor: Radislav Sedláček (radislav.sedlacek@img.cas.cz)

Project description: The project focuses on TIKI1 and especially TIKI2 (TRABD2A and TRABD2B genes) whose biological role in mammals is still purely understood. TIKIs function as negative regulators of the Wnt signaling pathway, mediating cleavages of N-terminal residues of a subset of Wnt proteins. Phylogenetic analysis shows that Tiki1 and Tiki2 orthologues are highly conserved among vertebrate and mammalian species although the Tiki1 is missing in rodents. The role of Tiki proteases will be studied in mouse and human systems and the work will start with the analysis of our TIKI2 –deficient mice. The aim of this study is to describe the pathophysiologic roles of TIKI2 (TIKI1).

Supervisor: David Staněk (stanek@img.cas.cz)

Project description: RNA splicing is a crucial step in gene expression during which non-coding introns are removed and exons are joined together. Introns have been found in all eukaryotic organisms but their function and origin remains mysterious. However, recently discovered unicellular marine predators contain new class of introns. This offers a unique opportunity to study a completely unexplored world in the RNA universe and reveal fundamental principles of intron evolution and function. This is a collaborative project with experts on unicellular organisms from the Institute of Parasitology and involves both bioinformatics as well as molecular biology approaches.

Candidate profile: M.Sc. in molecular, cellular or developmental biology, parasitology or bioinformatics.

 

 

Laboratory of Adaptive Immunity http://www.img.cas.cz/research/ondrej-stepanek/

PhD position in cell biology (with a taste of immunology)

Project 1

Project title: It is troublesome without BBSome
Supervisor: Martina Huranová (martina.huranova@img.cas.cz)

Project description: Primary cilium and immunological synapse are related structures. Both organelles concentrate sensory and signaling receptors of multiple signaling pathways. In addition, structural and functional establishment of these structures is dependent on polarized protein transport and remodeling of actin cytoskeleton. Bardet-Biedl syndrome (BBS) is a severe multiorgan disease (ciliopathy) caused by loss-of-function mutations in several BBS related proteins. BBSome is a complex of eight BBS proteins and regulates two key processes during ciliogenesis. First, BBSome transports multiple receptors to the ciliary membrane. Second, BBSome inhibits activity of RhoA GTPase, which regulates F-actin polymerization. The herein project aims to understand how BBSome regulates actin remodeling during ciliogenesis. Second part of the project will focus on the role of BBSome in the formation of the immunological synapse between T cells and antigen-presenting cells. The PhD candidate will analyze BBS4 deficient mice and generate and analyze BBS7 and BBS4 deficient cell lines. The experimental approaches will include fluorescence microscopy and superresolution microscopy, techniques of biochemistry and molecular biology and immunological assays.

Offer: We can offer enthusiastic, well-equipped research environment and sufficient funding. The research focuses on solving emerging questions in cell and developmental biology.

Candidate profile: M.Sc. or equivalent in cell biology, molecular biology or related fields. We are looking for a highly motivated and enthusiastic student with a strong commitment to science, wet lab experience (e.g. MSc. project), good laboratory practice and ethics. Previous experience with cell cultures, animal models, fluorescence microscopy, and/or methods in molecular/cell biology and biochemistry is an advantage.

 

Project 2

Project title: Track the Tregs
Supervisor: Ondřej Štěpánek (ondrej.stepanek@img.cas.cz)

Project description: Regulatory T cells (Tregs) are crucial players in establishing self-tolerance. However, some aspects of Treg biology are still poorly understood. It is unclear how highly self-reactive T cells decide between negative selection and Treg conversion in the thymus. The PhD candidate will address the role of Foxp3 transcription factor in this cell-fate decision checkpoint using transgenic animal models. Second part of the project will focus on the analysis of the role of pathogen specific Tregs during infection using monoclonal Tregs and Listeria monocytogenes infection. Third part of the project will analyze the heterogeneity of Treg population in the steady-state and during various disease conditions (infection, cancer, and autoimmunity).

Offer: We can offer enthusiastic environment of a young research team, well-equipped research environment and sufficient funding. The research focuses on solving emerging questions in immunology.

Candidate profile: M.Sc. or equivalent in immunology, cell biology, developmental biology or related fields.

Previous experience with animal models and immunological research is an advantage.

 

Project 3

PhD position in cell biology

Project title: Molecular mechanisms of inflammation.
Supervisor: Peter Draber (Peter.Draber@img.cas.cz)

Project description: Inflammation is a principal mechanism of body defense against invading pathogens and its proper mounting is critical for clearing infection. At the same time, the hyperactivation of pro-inflammatory pathways might lead to severe autoimmune disorders and cancer. The initial activation of the immune system requires pro-inflammatory mediators, such as TNF, IL-1, and IL-17. The binding of these cytokines to their receptors on cell surface triggers formation of complicated signaling complexes. Very tight regulation of these complexes is required to ensure adequate activation and termination of inflammatory signaling. However, the precise molecular mechanisms guiding the assembly and activity of these signaling complexes are still largely enigmatic. At first, the candidate will identify novel components of several pro-inflammatory signaling complexes (including IL-17 receptor signaling complex) using mass-spectrometry analysis. Subsequently, roles of the newly identified components will be studied in vitro by analyzing knockout cell lines generated by Crispr-Cas9 technology. Finally, the candidate will focus on the role of these molecules in vivo using animal models. Altogether, the successful candidate should finish her/his PhD study with deep theoretical knowledge in the field of inflammation and be highly skilled to perform up-to-date molecular biology methods and analysis of mouse models.

Candidate profile: M.Sc. or equivalent in cell biology, biochemistry, molecular biology, or a related field. We are looking for a highly motivated and enthusiastic candidate with deep interest in science. Prior laboratory experience is advantageous.

Research Topic: The PRDM9 (PR-domain 9) protein is an epigenetic factor important for both male and female fertility that determines the sites of meiotic recombination. PRDM9 variants contribute to non-allelic homologous recombination leading to genomic disorders and were found in sterile men. We identified mouse Prdm9 as the first vertebrate hybrid sterility gene. Prdm9 participates in our rodent models of complete sterility, time-dependent (semi)sterility reduced sperm count, and mild meiotic arrest.

Candidate profile: M.Sc. or equivalent in molecular genetics and/or reproductive biology, experience in work with rodents, basic bioinformatics, active English

 

 

Guest group of Genome Dynamics and Neurodegeneration

Project title: The mechanistic interplay between DNA strand break repair, RNA processing, and human neurological disease
Supervisor: Hana Hanzlikova (h.hanzlikova@sussex.ac.uk)
Co-supervisor: Keith Caldecott (k.w.caldecott@sussex.ac.uk)

Project description: DNA single-strand breaks (SSBs) are the most frequent DNA lesions arising in cells and are a major threat to cell survival and genetic integrity, as indicated by the elevated genetic deletion, embryonic lethality, and neurological disease observed if single-strand break repair (SSBR) is attenuated1. Based on our recent exciting data2 we will address the extent to which the impact of SSBs extends to other neurodegenerative diseases and to normal human ageing. In addition, the project will address the mechanisms by which SSBs trigger neurodegeneration, and will employ cutting edge techniques in molecular and cellular biology, including genome editing by CRISPR-Cas9 technology. The successful applicant will join a dynamic and well-funded laboratory with training opportunities in laboratories in both Prague and the UK.

For the project “Repeatome dynamics in the earliest evolutionary stages of apomictic plants”, funded by the Czech Science Foundation, we seek to the earliest possible date a highly motivated

PhD student in Cytogenetics

The project (duration 3 years) is aimed at a better understanding of mechanisms underlying the transition from sexual to apomictic reproduction. Apomixis is tightly connected with hybridization and polyploidization. Despite a great potential in agriculture, the genetic mechanisms of apomixis are still poorly understood. Hybridization causes genetic instability including a restructuring of the repeatome, the fastest evolving part of plant genomes. Bursts of transposable elements due to hybridization-induced genomic shock may trigger a switch to apomixis. In the project, sexual and apomictic Hieracium species will be investigated in an extensive breeding program, comparing artificial hybrids with natural apomicts of the same parentage as a model of hybrid speciation that may lead to the formation of apomictic lineages.

An interdisciplinary and international team of researchers from the Institute of Botany (www.ibot.cas.cz/en/) of the Czech Academy of Sciences and the Department of Botany of the Charles University in Prague (www.cuni.cz/UKEN-1.html) will tackle this complex biological question from various angles (cytogenetics, genomics, embryology, reproductive biology).

Responsibilities of the PhD candidate include karyotyping of plants, in situ hybridization (FISH, GISH) with a main focus on the localization of parental-specific repetitive elements using probes derived from NGS data as cytogenetic markers to investigate genome repatterning following hybridization. Further tasks include data processing and interpretation, presentations at international conferences and publications in IF journals.

Experience with karyological and cytological techniques, preferably in plants, is desired. The candidate should have an excellent command of English. Personal features should include reliability, patience, technical accuracy, flexibility, good social skills and the readiness to learn.

We offer creative work, the chance for personal development, a pleasant working atmosphere in a marvellous environment (Pruhonice Park, UNESCO World Heritage Site, www.pruhonickypark.cz/en/the-pruhonice-park/), and an excellent infrastructure at the Laboratory of Molecular Cytogenetics and Karyology (http://www.ibot.cas.cz/en/scientific-groups-and-laboratories/laboratory-of-molecular-cytogenetics-and-karyology/) under the leading of Dr. Alexander Belyayev. The PhD candidate will be enroled at Charles University in Prague, one of the oldest universities in Europe.

For more information, please contact Dr. Judith Fehrer (fehrer@ibot.cas.cz). Applications containing a motivation letter, a short CV and two references should be sent until 22. January 2017 to ibot@ibot.cas.cz.
