Life Sciences
This doctoral study programme is organized by the Faculty of Science in English and the studies are subject to tuition. There is an alternative option for the international applicants to be accepted in the free programme administered in Czech with the possibility of receiving a scholarship. The study language of the programme is still English (Czech is the administrative language). Before officially applying, please contact us at admission@sci.muni.cz to find all the necessary information related to the scholarship and see our FAQ’s.
What will you learn?
The aim of the study is to educate students in the field of life sciences and to prepare them as highly qualified specialists for scientific activities. The introductory part of the study concentrates on deepening theoretical and practical knowledge. At the same time, separate literary research on the assigned topic of the doctoral dissertation is being prepared. The core of students’ activities lies in their own scientific work. Students are guided by the supervisor to be able to independently implement all phases of a scientific project. They are also encouraged to the processing of the obtained experimental data methodologically relevant, as well as to their interpretation and subsequent presentation in various forms. The programme is highly multidisciplinary and, compared to the traditional study of biology, is more methodologically and analytically focused. Thanks to access to state-of-the-art infrastructure, students can better combine various biochemical, bioanalytical and visualization instrumental techniques with solving biological problems, which increases the impact of their scientific activities and their flexibility in the labor market, including positions in academia, e.g. within existing biotechnology companies or in newly emerging spin-offs.
The concept of the programme reflects the current level of scientific knowledge, the needs of the labor market, and overall trends in the field. At the same time, it benefits from the support system within the so-called CEITEC PhD School, which presents the concept of care for doctoral students involved in research teams at CEITEC and at the same time emphasizes expanding the competencies of the future graduates in socio-managerial, technological and soft skills. That will enable them to conduct their follow-up research in an efficient and modern way and provide them with a very good overview of the ethical aspects of research necessary for life sciences research and research and development in general.Life for Science. Science for Life.
The programme aims at the international employment of graduates. It is prepared in Czech and English versions, most subjects are taught, all seminars and, to a large extent, research is conducted in English. The environment at CEITEC MU is significantly international, so students are exposed to communication in English not only during official teaching but practically everywhere within CEITEC.
Practical training
An important contribution to the acquisition of practical skills of DSP students of Life Sciences is their natural involvement in research teams at CEITEC MU. In this way, students can immediately acquire the necessary practical skills for team management and research projects, acquire networking skills and directly engage in research projects and grants (including H2020 projects and ERC grants) to understand the issues of research funding. Students can also routinely use eleven uniquely equipped shared laboratories and gain significant practical experience in this form within the so-called internal internship, or in another institution in the Czech Republic as part of an external internship (recommended volume is 10 working days (80 working hours).
A compulsory part of the study obligations in the doctoral study program is completing part of the study at a foreign institution for at least one month, or participating in an international creative project with results published or presented abroad or another form of student direct participation in international cooperation.
The program supports Collaborative PhD, i.e. completing a doctoral project in cooperation with a commercial entity. That allows students to expose themselves to a more non-academic environment. Also, within the TAC system, students cooperate more often with experts from practice.

Co-translational quality control and its role in neural tissue
Supervisor: RNDr. Petr Těšina, Ph.D.
Ribosome-associated quality control (RQC) is crucial for degrading truncated nascent proteins produced on aberrant mRNAs. Mutations in RQC components cause neurodegeneration both in animal models and human patients. Moreover, RQC insufficiency and subsequent protein aggregation critically contribute to proteostasis impairment and systemic decline during ageing. The successful candidate will utilize a multidisciplinary approach to provide detailed mechanistic understanding of the critical human RQC system in combination with an in vivo study to reveal processes leading to RQC-driven pathological changes in neural tissue. He/she will utilize human cell cultures, protein expression and purification techniques and biochemistry methods to produce samples for cryogenic electron microscopy (cryo-EM). Comprehensive training in cryo-EM will be available to the successful candidate. The candidate will also have a unique opportunity to acquire expertise in the use of C. elegans as a model organism during a research stay at a collaborating laboratory in Bolzano (Italy).
Requirements on candidates:
The ideal candidate should have a background in either molecular biology, biochemistry, or structural biology. Experience with human cell culture work or protein biochemistry is a plus.

Deciphering the Argonaute Loading Mechanisms in RNA-Silencing Pathways
Supervisor: prof. Mgr. Richard Štefl, Ph.D.
critical step in gene regulation within RNA-silencing pathways, which are pivotal in both healthy and diseased
states of animals and plants. Despite over two decades of research into the microRNA pathway and RNA
interference, the precise mechanisms of miRNA strand selection and transfer to Argonaute proteins remain
elusive. We propose the existence of two distinct mammalian Argonaute loading pathways, orchestrated by
Dicer and heat shock protein chaperones, which both involve charged intrinsically disordered regions that
have been overlooked in previous structural studies. The PhD project aims to dissect these mechanisms
using electron cryomicroscopy (cryoEM). The objective is to elucidate the structures of critical complexes
involving heat shock protein chaperone/co-chaperone-Argonaute-RNA and Dicer-Argonaute-RNA
assemblies. By integrating cryoEM with functional analyses, the project aspires to establish the mechanistic
principles of Argonaute loading. The findings of this PhD project will be instrumental in advancing RNAbased
therapeutic applications and understanding one of the most crucial regulatory cellular processes.

Design of fusogenic peptides
Supervisor: prof. RNDr. Robert Vácha, PhD.
Membrane fusion is an essential biological process that plays a crucial role in neurotransmission,
intracellular trafficking, and immune responses. Despite its fundamental biological role and
potential application in drug delivery, the molecular understanding of membrane fusion and its
control remain elusive. This project is focused on the design of novel peptides and peptide
aggregates able to induce spontaneous fusion. The peptides have been selected based on their
biocompatibility and our exceptional experience with membrane-active peptides, including the
design of de novo sequences based on the elucidated mechanism. The first step will be to develop
a computational approach to determine the critical peptide properties required to destabilize or
stabilize key fusion states: membrane stalk, hemifusion diaphragm, and fusion pore. These
findings will then be used to de novo design peptide sequences where the fusogenic role of each
amino acid is known, providing the key advantage for customization for vaccination and drug
delivery. The computational results will be verified by fluorescence and electron microscopy.
Requirements on candidates:
Outstanding candidates with experience in computer simulations and with an MSc/PhD degree in
the fields of biophysics, soft matter physics, physical chemistry, computational chemistry,
statistical mechanics, or related fields. Experience with molecular dynamics simulations (with
GROMACS, CHARMM, NAMD, AMBER, LAMMPS, etc.) at the atomistic or coarse-grained level
would be an advantage.

Dishevelled internal affairs in Wnt signalling
Supervisor: Konstantinos Tripsianes, Ph.D.
Dishevelled (DVL) is the central hub of Wnt signal transduction that integrates and transduces upstream signals through distinct cytoplasmic cascades. Looking at the many DVL faces reported in literature, three salient features underlying its function in signaling can be highlighted: (1) it interacts with more than seventy binding partners, (2) it is heavily phosphorylated at multiple sites by at least eight different kinases, in particular by Ck1epsilon/sigma after Wnt stimulation, and (3) it consistently forms puncta in the cytosol, that are phase-separated self-assemblies also called liquid droplets.
Our working hypothesis is that DVL conformational plasticity mediated by the order-disorder interactions allows the combinatorial integration of phosphorylation input, partners binding, self assembly in droplets, and allosteric coupling, to exquisitely control signal routing. We integrate structural biology (NMR, SAXS, X-ray, MS-HDX) and biophysical techniques (FRET, ITC, BLI) with cellular readouts (TopFlash, BRET) to understand DVL structure, function, and regulation. Candidates can choose among three open questions, that if resolved, will have significant impact on Wnt research.
1) Does disorder provide new contexts to structured domain(s) and, hence, enhance the DVL functional space associated with them?
2) Is there a direction, order or hierarchy in the phosphorylation of individual S/T sites and clusters in DVL?
3) What are the physical behaviors associated with intrinsic disorder and their connection to DVL liquid-liquid phase separation?

Effect of lipid asymmetry on membrane protein function
Supervisor: prof. RNDr. Robert Vácha, PhD.
compositions between the two leaflets. However, most studies to date have focused on symmetric
bilayers. This project addresses this gap by integrating molecular dynamics simulations with
experimental techniques such as solid-state NMR spectroscopy and scattering methods. The
primary aim is to elucidate the structural and dynamical properties of lipids in asymmetric
membranes, particularly their interactions with integral membrane proteins, with an emphasis on
bacterial lipid compositions. Initial step will involve determining lipid chain order parameters,
bilayer structure, and lipid dynamics. Subsequently, lipid-protein interactions will be assessed,
focusing on lipid-induced modulation of enzymatic activity in two bacterial proteins: OmpLA, a beta-
barrel protein, and GlpG, an alpha-helical transmembrane protein. The findings will offer key insights
into the role of lipid asymmetry in biological membranes and its influence on membrane protein
function, with potential applications in the development of lipid-targeted therapeutics and
biosensors for pharmaceutical and biotechnological use.

fibrillization of tau protein into neurofibrillary tangles. Studying how different factors
influence the formation of protein fibrils is the key to understanding these
neurodegenerative processes. The main aim of this PhD project will be the
characterization of conformational changes towards the formation of tau fibrils due to
their truncations, phosphorylation, and interaction with 14-3-3 proteins. An
interdisciplinary approach combining biomolecular NMR, biophysical interaction
techniques, and computational methods will be applied. Special emphasis will be used
for the applying of solution NMR spectroscopy for the monitoring of secondary structure
propensities and proline conformations within Tau and alpha-synuclein protein as well as
binding epitopes of their selected binding partners.

Functions of cyclin-dependent kinase 11 (CDK11) in regulation of gene expression and tumorigenesis
Supervisor: Mgr. Dalibor Blažek, Ph.D.
CDK11 is ubiquitously expressed in all tissues and the CDK11 null mouse is lethal at an early stage of development indicating an important role for Cdk11 in the adult as well as during development. CDK11 is believed to play a role in RNAPII-directed transcription and co-transcriptional mRNA-processing, particularly alternative splicing and 3end processing. However, its genome-wide function in regulating the human transcriptome is unknown. Notably, several recent studies identified CDK11 as a candidate essential gene for growth of several cancers therefore, understanding the molecular mechanism(s) of CDK11-dependent gene expression would be also of significant clinical interest. In this research we will use various techniques of molecular biology and biochemistry to characterize genome-wide role of CDK11 in regulation of gene expression and tumorigenesis.

Characterization of cyclin-dependent kinase 12 (CDK12) substrates and their roles in regulation of transcription and tumorigenesis
Supervisor: Mgr. Dalibor Blažek, Ph.D.
Cdk12 is transcriptional cyclin-dependent kinase (Cdk) found mutated in various cancers. In previous studies we found that Cdk12 maintains genome stability via optimal transcription of key homologous recombination repair pathway genes including BRCA1. Apart from the C-terminal domain of RNA Polymerase II other cellular substrates for both kinases are not known. In this research we propose using a screen in cells carrying an analog sensitive mutant of CDK12 to discover its novel cellular substrates. The substrates and their roles in normal and cancerous cells will be characterized by various techniques of molecular biology and biochemistry.

Supervisor: prof. MUDr. Mgr. Marek Mráz, Ph.D.
The aim of this research is to develop and use models mimicking lymphoid microenvironment to study novel therapeutic options, e.g. drugs targeting CLL proliferation, development of resistance in long-term culture or combinatory approaches, which cannot be analysed in experiments based on conventional culture of CLL/lymphoma primary cells. This project will utilize models developed in the laboratory and will further optimize and modify them. We have recently developed a co-culture model that is allowing to induce robust proliferation of primary CLL cells, something that was virtually impossible for decades (Hoferkova et al, Leukemia, 2024). Using kinase inhibitors, the biology of CLL and responses to targeted treatment will be interrogated. The student will utilize various functional assays, RNA sequencing, genome editing, drug screening etc., with the use of primary patient’s samples and cell lines. The research might bring new insights into the microenvironmental dependencies and development of resistance to targeted therapy.
Requirements on candidates:
Motivated smart people who have the “drive” to work independently but are also willing to learn from other people in the lab and collaborate.
Candidates should have a master’s degree in Molecular biology, Biochemistry, or a similar field and have a deep interest in molecular biology and cancer cell biology.

Nucleic Acids Sensing
Supervisor: doc. Mgr. Lukáš Trantírek, Ph.D.
Dynamic transitions between B-DNA and non-canonical DNA conformations, such as G-quadruplexes, i-motifs, and Z-DNA, contribute to the regulatory control of genome integrity and gene expression, playing an essential role in defense against invading pathogens. The function of these structures is linked to their dynamic polymorphism, which allows them to adapt sensitively to changes in the intracellular environment due to cellular stress and physiological oscillations. The project will explore the mechanisms of transferring information from the intracellular environment to the dynamic structural equilibria of DNA as the cell’s physiological state changes.
Requirements on candidates:
The candidate is expected to have theoretical and practical knowledge of biomolecular NMR spectroscopy and an interest in the biology of nucleic acids.

organelles self-assemble based on weak protein-protein interactions between intrinsically
disordered domains. Although specific cellular conditions can alter these interactions, the
relationship between the two remains unclear. This project focuses on the droplets involved in
genome transcription, where post-translational modifications control droplet composition and
regulate transcription. The project will explore the relationship between sequence and
environment using multi-scale simulations, advanced sampling techniques, and novel protein
parameterizations. The research is closely linked to collaborations with leading experimental
teams and will be discussed in more detail during the interview. The expected findings are
important not only for the fundamental understanding of biological processes but could also aid
in designing new treatments for numerous diseases, including cancer.
Requirements on candidates:
Outstanding candidates with experience in computer simulations and with an MSc/PhD degree in

Ribosome assembly mechanisms
Supervisor: Mgr. Gabriel Demo, Ph.D.
coordinated folding, modification, and binding of ribosomal RNAs (rRNAs) and proteins (r-proteins) with the
assistance of various assembly factors. The absence or dysfunction of these factors often results in slow
cell growth and improper ribosome assembly. Under such stress conditions, cells may employ stress-related
factors to regulate ribosome assembly. However, the biological and structural connections between
ribosome assembly and the stress response remain poorly understood compared to other aspects of
ribosome function.
This thesis aims to unravel the intricate relationship between ribosome biogenesis and stress response
mechanisms in bacteria and archaea. By analysing ribosomal fractions from bacterial strains lacking key
maturation factors, we seek to identify novel ribosome-associated factors or repurposed translation factors
involved in ribosome reassembly. Single-particle cryo-electron microscopy will provide structural insights
into ribosome reassembly processes using ex vivo ribosomal complexes. Additionally, the investigation of
the archaeal translation system, an understudied area, may reveal novel proteins linked to ribosome
maturation. This research promises to uncover previously unknown mechanisms of ribosome reassembly in
bacteria with defective ribosome maturation and identify novel factors influencing ribosome assembly in
archaea.
Requirements on candidates:
We are seeking a PhD. candidate who was trained in structural biology (mainly cryo-electron microscopy),
worked in translation field or in general biochemistry and is a motivated person with collaborative mind set.

cryo-electron microscopy and tomography to characterize replication intermediates of phage LE3 infecting
Leptospira. The in situ data collection will be enabled by the dimensions of leptospira cells, which are 100 nm

genome packaging. These processes cannot be studied in vitro because of the challenges of preparing the
corresponding complexes in functional form in sufficient amounts.

Krasny of Institute of Microbiology, Academy of Sciences of The Czech Academy of Sciences. Krasny’s lab
discovered several proteins of Gram-positive bacteria that play so far little understood roles in transcription
regulation. The goal of the project is to combine structural biology approaches to establish relation between
structure, biophysical properties, and function of these proteins and other poorly understood bacterial
transcription factors. The particular aims include maping of transient interactions of the delta subunit with
the RNA polymerase core of Bacillus subtilis, interplay between delta subunit and sigma factors, interactions
of a recently discovered transcription factor MoaB2 with mycobacterial sigma factors and RNA polymerases.
Cryo-electron microscopy will be used as a major tool to study structures of the proteins in complexes with
RNA polymerase. A particular attention will be paid to dynamics of the proteins, that often contain large
disordered regions, where cryo-EM data will be combined with results of NMR spectroscopy. As alternative
methods, FRET (and potentially EPR in collaboration with V. Laguta) using advanced labelling techniques
will be used. The project should result in publications in respected journals with the student being the
(shared) first author.

Translation in the context of human host-pathogen interaction
Supervisor: RNDr. Petr Těšina, Ph.D.
Proteins are produced by ribosome-catalyzed translation of mRNAs in all domains of life. Translation is also critical in the context of human host-pathogen interaction where the ribosome, as the central molecular machine for genetic information expression, is the subject to numerous regulatory and quality control events and pathological interventions. The strategies adopted by viruses to reprogram translation and co-translational quality control machinery to promote infection are poorly understood. Thus, there is an urgent need for further research in this area to develop effective strategies for combating viral infections. The successful candidate will study how viruses affect human translation and co-translational quality control with the aim of providing high-resolution structures of large macromolecular assemblies. He/she will utilize human cell cultures, protein expression and purification techniques and biochemistry methods to produce samples for cryogenic electron microscopy (cryo-EM). Comprehensive training in cryo-EM will be available to the successful candidate.
Requirements on candidates:
The ideal candidate should have a background in either molecular biology, biochemistry, or structural biology. Experience with human cell culture work or protein biochemistry is a plus.
