Molecular cell biology

Postdoctoral researcher – Translational control of the eukaryotic gene expression

Postdoctoral position is available for either a molecular biologist or a computational biologist (specialist in bioinformatics) to study a role of physical and functional interactions between translation initiation factors and 5’ and 3’ untranslated regions (UTRs) in a control of mRNA translation and stability. Both canonical and non-canonical translation initiation factors will be in a focus of the study. The main models currently employed in the laboratory are human cell lines (derived from acute leukemia), budding yeast, hepatitis C virus and the beetle Tribolium castaneum. A broad selection of models and used techniques allow us to ask questions ranging from those covering basic functions of translational apparatus to questions concerning associated evolutionary and developmental consequences. Deregulation of translation initiation and mRNA stability plays a key role in many human pathologies including cancer, leukemia and viral infection. We always try to expand our basic science projects to understanding of the corresponding diseases and thus we often co-operate with leading academic institutes and clinics.

Qualification and experience. We are looking for a highly motivated, enthusiastic and qualified researcher who would like to join our team and effort. If molecular biologists, candidates should have an experience either in RNA analyses and biochemistry or in cell biology techniques including confocal microscopy, life cell imaging and FRET. If computational biologists, candidates should have, besides basic knowledge of molecular genetics, strong background and interest in computational data analysis, experience with Linux/Unix shell, knowledge in database technologies and solid programming skills. Strong communication skills and the ability to interact and co-operate well with other scientists and students in the team are essential.

Postdoctoral Researcher –Splicing in the regulation of gene expression in yeast

Postdoctoral position is available to study the regulation of splicing and the interplay between transcriptionand pre-mRNA processing in yeast. Candidates should be interested in the molecular mechanisms of gene expression regulation and should have experience in molecular genetics, biochemistry, RNA analyses and cell biology/microbiology.

The Laboratory is interested in the mechanisms of splicing regulation and the relationship between splicing and transcription using yeasts as model organisms. Both Saccharomyces cerevisiae and Schizosaccharomyces pombe are used to study evolutionarily conserved regulatory factors of the synthesis and maturation phases of transcript production. Introns in S. cerevisiae are relatively few and short; the spliceosomes still contain an almost complete array of splicing factors as compared to other organisms (S. pombe or higher eukaryotes). The study of splicing factors in an organism with reduced intronome should help to identify interactions that link splicing to other gene expression processes.

Potential aims include:

- Regulation of RNA helicases during the splicing cycle

- Factors and molecular mechanisms of coupling of transcription initiation, elongation, and splicing

- Mechanisms that coordinate transcript production & maturation with cell cycle progression

- Role and regulation of cyclophilins in the spliceosome of S. pombe

Well-equipped DNA and flow cytometric laboratories are available.

Potential aims - thorough comparative study of the evolutionary history of three intricate polyploid complexes from three different tribes of Brassicaceae in order to get a more general insight into patterns and processes of polyploid evolution in natural conditions. Particular questions addressed will include: What is the rate of auto- vs. allopolyploidy in three studied polyploid complexes? Does the evolution repeat itself? Are there any independent polyploid lineages originating from the same parental combinations? What are the main differences in evolutionary patterns between related diploid and diploid/tetraploid species complexes evolving in the same area and environmental context?

Ecology

Postdoctoral Researcher – Genetic variation of model taxa of crustaceans and their associated (micro)parasites

Postdoctoral position is available at the Department of Ecology on evolutionary biology of freshwater crustaceans. The ideal candidate for this position has strong background in animal ecology and evolutionary biology (an experience with host-parasite interactions is a plus), has experience with various DNA laboratory methods and analysis of resulting data, and is willing to learn new methods and contribute to both field- and labwork.

The research group is particularly interested on diversity, evolution, and ecology of two important crustacean taxa – cladocerans (mainly Daphnia) and freshwater crayfish. Furthermore, we are involved in studies on interactions of these crustaceans, as hosts, with certain microparasites (in particular, an oomycete Aphanomyces astaci causing crayfish plague, and microsporidians infecting Daphnia).

The postdoc should contribute to these research questions by genetic analyses of populations of selected crustacean species complexes. Topics under study will include (i) spatial distribution of evolutionary lineages and phylogroups, (ii) patterns resulting from interspecific hybridisation (or reproductive isolation) between coexisting closely related lineages, (iii) impacts of parasitism on genetic variation of host populations, (iv) DNA-based detection of parasite infection and quantification of parasite load, and (v) analysis of parasite diversity. Different molecular approaches are likely to be used, such as standard sequencing, microsatellite analyses, real-time PCR, and AFLP.
