Molecular and personalized medicine
Laboratory of Experimental Medicine
Group of Dr. Hajdúch is one of the pioneers of personalized medicine in the Czech Republic. We focus on the molecular basis of human diseases, especially cancer. We are involved in identification and description of metabolic and signaling pathways, genetic and epigenetic changes causing human cancers. This includes tumors of various origins and underlying mechanisms of carcinogenesis, including genetic tumor predisposition syndromes, infectious or inflammatory diseases. Our research generates new therapeutically exploitable molecular targets and biomarkers for the diagnosis and targeted treatment of human disorders.
In the field of drug research and development, the group focuses mainly on anticancer drugs, specifically small molecules, including natural compounds. We test the biological activity of synthesized chemical compounds, in the case of biologically active substances, we identify the mechanisms of action through the methods of cellular biology, biochemistry, chemical proteomics and genetics. In the case of known molecular targets, we perform high-throughput screening and screen for pharmacological inhibitors or activators of the biological activity of the molecular target or cellular phenotype. Furthermore, in collaboration with medicinal chemists we optimize the chemical structures to increase effectiveness and pharmacological properties of candidate molecules. Promising compounds enter pre-clinical testing and few of them proof-of-concept first in man or drug repurposing clinical trials.
In the field of biomarkers, we focus mainly on their identification, validation and implementation for diagnostic, prognostic and predictive purposes in cancer research and for routine clinical use. These biomarkers can be used in situations directly related to patient care, drug development and research. To this end, we leverage our expertise and knowledge in the identification and validation of biomarkers at the multiomic level through comprehensive profiling and analysis of the genome, transcriptome, proteome and metabolome. We perform comprehensive genomic, metabolic and proteomic analyses to find alterations of signaling and regulatory pathways in healthy versus tumor cells. Selected validated biomarkers are subsequently developed as diagnostic kits or directly licensed to industrial partners.

| Souhrn: | 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. |

| Souhrn: | 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. |

| Souhrn: | 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. |

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. |

| Souhrn: | 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. |

| Souhrn: | 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. |

| Souhrn: | 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. |

| Souhrn: | 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. |

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. |
