Impact of Nucleosome Positioning in Promoters on Transcription Regulation for Selection of Expression Activating Transcription Factor Binding Sites
(2025-10-16)Gene regulation processes are crucial for development and the adaptation of cells, tissues or whole organisms to changing environments. Nucleosome positioning in promoter regions is of pivotal importance in gene regulation, ... -
Unraveling the Intercellular Interactions driven by Wnt-ß-catenin pathway in cardiac remodeling
(2025-08-29)Heart failure (HF) is the most common cardiovascular disease (CVD) and, despite significant pharmacological progress, it remains the leading cause of morbidity and mortality globally. One of the hallmarks of HF progression ... -
Super-Resolution Imaging Approaches To Determine The Organization of B Lymphocyte Surface Receptors
(2025-08-21)This thesis presents a multidisciplinary investigation into B cell membrane biology andnanobody-based molecular targeting, spanning the development of new imaging techniques,a novel nanobody discovery platform, and functional ... -
Functional characterization of solute carriers with emphasis on proton-coupled organic cation antiporters
(2025-07-04)Solute carriers (SLCs) play an important role in the uptake of natural compounds and medically relevant drugs into various tissues, including the blood-brain barrier (BBB). Many cationic drugs rely on carrier-mediated ... -
Evaluation and Targeting of the Metabolic Signature of Human Pancreatic Ductal Adenocarcinoma Subtypes
(2025-03-13)Pancreatic ductal adenocarcinoma (PDAC) presents significant therapeutic challenges due to its pronounced tumor heterogeneity and complex metabolic reprogramming within the tumor microenvironment. In this study, advanced ... -
Misp53 mutation-specific oncogenic transcription factor complexes in PDAC progression
(2024-07-02)Pancreatic ductal adenocarcinoma (PDAC) is projected to become the second-leading cause of cancer related death by 2040 with a 5-year survival rate of only 11%. PDAC aggressiveness is attributed to its high heterogeneity ... -
3D imaging of immune cell reaction in pancreatic cancer organoids: the response to a nanovaccine therapy
(2024-06-27)This PhD thesis explored the use of patient-derived organoids (PDOs) obtained from tumor tissue, to address research limitations and therapeutic challenges in pancreatic ductal adenocarcinoma (PDAC), characterized by a ... -
Defining the Role of Chromatin Remodeling Complexes in Control of Master Transcription Factor Networks in Pancreatic Cancer Subtype Switch
(2023-10-19)Pancreatic ductal adenocarcinoma (PDAC) is a highly heterogeneous disease characterized by a dismal prognosis of 11%, projected to be the second-leading cause of cancer-related death by 2040. This urgent clinical challenge ... -
Modulation of HSF1 activity by p53 and its impact in cancer therapies
(2023-07-13)The tumor suppressor p53 (TP53) is mutated in ~70 % of colorectal cancer (CRC) cases. Of these cases, approximately 80 % undergo subsequent p53 loss-of-heterozygosity (p53LOH), losing the remaining wildtype p53 (WTp53) ... -
Stereoselectivity in Drug Membrane Transport by Solute Carriers (SLCs)
(2023-07-10)About 50% of all small molecule drugs are racemic mixtures of usually two stereoisomers. In the living organism, these drugs interact with a mostly chiral environment of unichiral amino acids, sugars, hormones, and other ... -
In vivo application of CRISPR/Cas9 mediated gene re-expression in the failing mouse and human myocardium
(2022-11-17)Transcriptional adaptation in cardiomyocytes precedes cellular deterioration and functional decline upon myocardial stress and damage resulting in heart failure progression. The re-activation of WNT/β-catenin (CTNNB1) ... -
Interfering with critical steps of the viral replication cycle to diminish SARS-CoV-2 propagation
(2022-10-07)The ongoing COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, has so far infected more than 0.5 billion people worldwide, with at least 6.3 million deaths, and constitutes one of the largest global health ... -
Gene-expression control in early and late-onset dementia
(2022-10-05)Mutations in genes that control epigenetic gene expression, especially the machinery that controls Histone 3 lysine 4 (H3K4me) methylation, are over-represented in intellectual disability disorders. It is mediated by both ... -
Pre-Clinical Assessment of Cardiac and Lung Fibrosis Using Next Generation Imaging Modalities
(2022-03-08)Fibrosis, defined as an excessive deposition of connective tissue components causing disruption of the physiological architecture and organ malfunction, is commonly associated with high morbidity and mortality. The global ... -
MCL-1, BCL-xL and Casp-3 as key regulators in thymus homeostasis and thymic epithelial tumors
(2021-12-23)As a primary lymphatic organ, the thymus is responsible for T cell development and the establishment of the adaptive immune system. The homeostasis and proper function of the thymus epithelium require the strict regulation ... -
