Laboratory of Experimental Medicine
The Laboratory of Experimental Medicine (LEM) was established in 1998 at the Department of Pediatrics, Faculty of Medicine and Dentistry, Palacky University and University Hospital in Olomouc. Later in 2010, the LEM became a moving force in building-up and establishment of the Institute of Molecular and Translational Medicine.
Our researchers are organized to research groups and perform molecular, cellular and integrative research at the highest international level and to train a new generation of successful scientists. We study biological processes that govern normal and pathological human bodily functions that are involved in disease pathogenesis. Albeit our research is disease agnostic, most of our expertise relates to cancer, inflammation, infection, rare diseases and neurodegeneration. Our spectrum of research ranges from basic and translational science, including research and development of small molecules, radiopharmaceutics, identification of new therapeutic targets, drug repurposing, first use of molecules in man (Phase I trials), biomarker identification and validation trials, development of in vitro diagnostics, through to real-world evidence studies using routinely collected data.Several of our research environments have been recognized as outstanding both at the national and European levels. We also strive to stimulate our young researchers with our enthusiasm for research and wish to increase their interest in both basic and applied sciences. We expose them to the most up-to-date science, cutting edge technologies and prepare them for lifelong learning in their future careers.

| Summary: | One of the main goals of chemoinformatics is development of new compounds with desired properties or activities. Many de novo design approaches were suggested so far. The designed compounds should satisfy multiple criteria, e.g. synthetic accessibility, novelty, diversity, selectivity, etc. Generators of chemical structures satisfying these criteria are a core of all de novo design approaches. Available approaches often result in synthetically hardly accessible structures or limit their diversity and novelty. Within this study a new fragment-based approach for structure generation will be implemented which will result in chemically valid structures and will provide flexible control over their diversity, novelty and synthetic accessibility. This will be used for development of de novo design approaches based on molecular docking, pharmacophore modeling to generate compounds which will be able to fit to a binding site of a given protein. This can be used for development of novel compounds and for optimization of structures of available ligands. Developed approaches should be implemented in open-source software tools. |

| Intended for: | Doctoral training |
| Summary: | Pharmacophore modeling is a powerful approach to encode possible protein-ligand interactions and searching of new promising compounds in large libraries. So far, almost all available software for pharmacophore modeling is proprietary and implemented approaches have some limitations to efficiently work with big data. Within this study a new approach to represent 3D pharmacophores as hashes will be implemented. This representation will make it possible to quickly identify similar pharmacophores in large data sets. This property can be used to develop a new alignment free approach to ligand-based pharmacophore modeling. The developed 3D pharmacophore hashes will help to identify representative pharmacophores retrieved from molecular dynamic simulation of protein-ligand complexes. These developments will increase success rates of future screening campaigns and should be implemented in open-source software. |

| Summary: | Although hundreds of biological databases are available, a richly annotated database of anti-aging compounds with diverse mechanisms of action has been missing. The aim of the project is to create a database of compounds with anti-aging activity that would offer a rich annotation of both compound and involved biological mechanisms. The data will be collected from a wide range of public databases, by text-mining of scientific literature and patents as well as from results of in-house high-throughput screening. The data will be used for formulation of new hypotheses of mechanisms of aging as well as for identification of novel anti-aging compounds. |

| Summary: | The study of ADME properties of a potential drug that are part of the IMTM chemical library - obtained by national or international cooperation belongs to one of the first steps in predicting potential drugs. In vitro models generate many ADME parameters, including chemical, plasma and microsomal stability, plasma protein binding and proportion of passive diffusion as a transport mechanism. The Caco-2 and MDCK-MDR1 permeability assays are established models of intestinal and blood-brain barriers, respectively. Analysis of samples is performed using a Agilent RapidFire 300 - rapid online solid phase extraction with subsequent detection of the mass spectrometer Qtrap 5500 (AB Sciex) - RF/MS. High-Throughput Mass Spectrometry System RF/MS delivers ultrafast, label – free analysis of native compounds for biochemical assays in ADME and provide throughput speeds of 6 to 10 seconds per sample. |

| Summary: | The student will employ modern in vivo imaging techniques namely positron emission tomography, single-photon emission tomography, computed tomography and optical imaging in order to elucidate effect of novel anticancer or antimicrobial agents. The other part of the project will be assessment of novel radiotracers directed towards targets expressed by tumour cells or by microbial pathogens. Daily work routine will include all proper working steps common in radiopharmacy, i.e. starting with gaining an radioisotope from dedicated source, radiolabelling of selected compound, quality control (HPLC/TLC), stability tests, in vitro testing of biological properties and finally in vivo procedures (biodistribution, static/dynamic imaging). Expected previous education includes medicine, pharmacy, pharmacology or related field. |

|---|---|
| Supervisors: | Das Viswanath M.Sc., Ph.D. |
| Available: | 1 |
| Intended for: | Doctoral training |
| Summary: | Hypoxia is a prominent feature of different solid tumor types. A central component of hypoxic adaptation is the stabilization of hypoxia-inducible factor-1 (HIF-1), a key transcriptional regulator of hypoxia that orchestrates the transcriptional regulation of genes involved in a plethora of cellular processes. Considering the multiple roles of HIF-1 in cancer, interest in novel small-molecule inhibitors of the HIF-1 pathway has steadily increased over the past 10 years. However, despite extensive research, no specific inhibitor of HIF-1 has been brought to the market, making the field still ripe for further exploration. The goal of the present work is to utilize the potential of a combination of 2D and 3D cellular models for identification and characterization of inhibitors of HIF-1 and/or HIF-1 pathway by screening in 2D cultures, and lightsheet microscopy and mass spectrometry studies in spheroid cultures. |

| Summary: | Recently, we identified several novel modulators of alternative splicing with the ability to increase expression of wild-type transcripts of several genes relevant for neurodegeneration or cancer. However, mechanisms of action of those promising compounds remains unclear. The aim of the project is to (i) identify molecular targets and relevant pathways, (ii) design assays for high-througput screening of a library of chemical compounds, and (iii) to identify novel structural types of active compounds. |

| Summary: | Mechanisms of tumor cell resistance to newly developed and existing nucleoside analog cytostatics will be studied. These drugs are used in most anti-cancer therapy protocols and the emergence of drug resistance is a major problem in the treatment of cancer patients. Resistant cell lines prepared in the past will be studied to identify the key mechanisms of resistance, which will be carried out by their detailed characterization using cell biology, but also proteomics and molecular genetics. The significance of the identified changes will be further verified on clinical material and will be applied in the development of new anticancer drugs from this class. |
| Project: | The role of tumor hypoxia in the acquisition of resistance to microtubule-targeting drugs |

| Supervisors: | Das Viswanath M.Sc., Ph.D. |
| Available: | 1 |
| Intended for: | Doctoral training |
| Summary: | Hypoxia is one of the major factors causing resistance to microtubule-stabilizing drugs (MSDs) and other non-microtubule drugs used in chemotherapy. Hypoxia results in changes in tubulin conformation, expression of tubulin isotypes and metabolic pathways that make cancer cells less susceptible to paclitaxel, a taxane used extensively in the treatment of solid tumors. Recent cellular studies have shown that non-taxane MSDs with a similar mode of microtubule stabilization to paclitaxel is more effective in hypoxic cancer cells than paclitaxel. Due to a different microtubule-binding site, we hypothesize that non-taxane MSDs may have a better cytotoxic effect in cancer cells under hypoxia. The goal of this project is to study the anti-cancer effect of non-taxane MSDs in hypoxic ovarian and cervical cancer cell models. |

| Summary: | High-risk human papillomavirus infection (HPV infection) is associated with several cancers such as cervical, vaginal, vulvar, head and neck, anal, and penile carcinomas. Nearly all cervical cancers are caused by HPV infection. Despite available vaccination and cervical cancer screening program, cervical cancer is one of the most common types of cancer affecting women worldwide. Main problems of cervical cancer screening are low participation rate and low sensitivity of cytology which is still used in the majority of cervical cancer screening programs. Solution could be the transition to primary HPV screening and the sending of self-sampling devices to cervical cancer screening non-attenders. The best strategy for enrolling Czech women in the screening program will be analysed during this project. Obtained samples will be tested for the presence of HPV DNA and the presence of other molecular biomarkers important in viral clearance and cervical cancer progression/regression. Discoveries will lead to identification of biomarkers for early diagnosis, disease progression or triage strategies. The aim of the project is to clarify the best strategy for enrolling women who do not attend cervical cancer screening program. The second aim is to study genetic and proteomic profile of HPV positive/negative women with normal/abnormal cervical cytology as well as genetic variants of HPV and its importance for regression/progression of the disease. Skills to be taught include biochemistry, molecular biology, bioinformatics and cell culture. This is an ideal project for a student who wishes to pursue higher studies in cancer research. The project will use various techniques including PCR, in situ hybridization, next generation sequencing, mass spectrometry. |

| Summary: | Clonal hematopoiesis of indeterminate potential (CHIP) has recently been described as a common phenomenon associated with aging. It is characterized by the accumulation of somatic mutations in cells of the hematopoietic system. Although CHIP is manifested by the expansion of certain cell clones, this condition is not accompanied by any morphological features of hematological neoplasia. However, it has been shown that the incidence of clonal hematopoiesis correlates with increased overall mortality and the risk of developing malignant transformation of hematopoietic cells as well as cardiovascular disease, such as ischemic stroke. To what extent and by what mechanisms clonal hematopoiesis contributes to disease development remains a question of current research. The main aim of the project will be to pinpoint the principal cells carrying CHIP somatic mutations, and to study their role in development and maintenance of atherosclerotic plaques, especially of those involved in development of stroke. The comparison of the phenotype of CHIP positive and negative cells will be of special interest. The use of cellular models not only include different types of leucocytes but circulatory progenitor endothelial cells as well. The study will involve elderly subjects with the positive presence of CHIP (>65 years). Subject will be characterized based on the presence or absence of ischemic stroke and the presence or absence of carotid stenosis by our clinical collaborators. The presence of somatic variants in 38 selected genes associated with CHIP will be tested in subjects of interest within our research group. The project will use various techiques including FACS, MACS, cell cultures, DNA isolation from small amount of cells, a highly sensitive sequencing method for DNA genotyping allowing detection of variant with less than 1% allelic frequency, DNA/RNA sequencing library preparation, deep massively parallel sequencing of panel of genes using unique molecular barcodes/indices, RNAseq, bioinformatics and data analysis with possibilities of calculations using high performance computing cluster, data management and statistical evaluation. |

| Summary: | Cancer is the second leading cause of death in the western countries. Early diagnosis and targeted therapy improve the therapeutic outcome. With the emergence of new biotechnologies, diagnosis can be made early and precisely, and the knowledge of tumor molecular genetics can identify the most appropriate therapy for a particular patient. The sensitivity of modern molecular methods makes it possible to characterize the tumor properties from sites remote from the primary tumor using patient's blood. The subject of the offered study program is the identification of new prognostic and predictive biomarkers of cancer using liquid biopsies. This is particularly the analysis of circulating tumor cells (CTCs), circulating free tumor DNA (ctDNA) and circulating miRNAs. The aim of the project is to further implement a liquid biopsy concept into the diagnosis and therapy monitoring of solid tumors, especially colorectal, breast, lung and CNS tumors. These include therapy response and resistance monitoring, identifying new therapeutic targets and estimating disease prognosis. The project will provide training in widely-used, transferable techniques, including circulation tumor cells capture system, digital droplet PCR, reverse-transcription qPCR, RNA-seq, single cell analyses, xenografts models and other multi-omics methods. We are looking for candidates with a background in Molecular Biology, Medicine, Cell Biology or a related area, who are enthusiastic about investigating novel approaches in cancer diagnostic that have significant potential for public health. |
