Memory capacity of flow network morphology
(2023-02-13)Adaptive flow networks are ubiquitous in our world. From animal blood vasculature to plant water vasculature and organisms shaped as flow networks, Physarum polycephalum, flow networks are abundant in biology with their ... -
Unraveling the Role of TET3 in regulating EndMT in Cardiac Fibrosis
(2023-02-10)DNA methylation and subsequent silencing of gene expression is associated with disease states including tumorigenesis and fibrosis. Although DNA methylation is a dynamic and reversible process, the mechanisms of and ... -
Epitranscriptomic Regulation in Synaptic Plasticity, Aging and Neurodegeneration
(2023-02-03)The regulation of synaptic transmission and plasticity is essential for correct brain function, especially for learning and memory, while the weakening of synaptic transmission and loss of plasticity are hallmarks of the ... -
Sleep control by TFAP2a and TFAP2b transcription factors in mice
(2023-01-31)Sleep is a universal behavior that exists across species. We previously found that deletion of transcription factor APTF-1 induces sleep loss in C. elegans and Drosophila. In mammals, sleep has two states: rapid eye movement ... -
Turbulence Measurements in Flows with Particles
(2023-01-31)Despite the ubiquity of turbulent flows in nature, a general solution to the governing equations of motion remain elusive. These equations are nonlinear and nonlocal, and they describe a chaotic system with multi-scale ... -
Characterization of the Complexin - SNARE Protein Network in Different Synaptic Systems
(2023-01-24)At neuronal synapses, the exocytotic SNARE complex is formed by Syntaxin 1, SNAP25 and Synaptobrevin 2. Complexin (Cplx) regulates the SNARE function to achieve the high speed and spatial precision of synaptic vesicle ... -
Mechanics and Motility of Epithelial Cells: From Single Cell Behavior to Collective Migration
(2023-01-13)Mechanical behavior of cells plays a crucial role in a plethora of biological processes. Despite its importance, this aspect of life science has only more recently gained increasing interest. Yet, without mechanical force ... -
Validation of novel protein-protein interactions in Bacillus subtilis
(2023-01-12)Protein-protein interactions are the basis for many biological processes in the cell. Understanding these interactions is crucial for the general analysis of how the cell functions and the potential identification of ... -
A Minimal Approach to the Dynamic Regulation of Biomolecular Conformation
(2022-12-14)Allostery is the key mechanism enabling a “remote” regulation of the activity of proteins and other biological macromolecules. It forms the basis for controlling various inter- and intracellular processes. Allosteric ... -
Translation Termination in Human Mitochondria: The Role of mtRF1 and mtRF1a
(2022-12-09)Translation termination is the last step of ribosomal protein synthesis. Dedicated translation factors are imported into mitochondria to convert the information stored in the retained mitochondrial DNA (mtDNA) and to ... -
Automated STED microscopy for cell-biological high-throughput assays
(2022-11-28)In the past decade, super-resolution fluorescence microscopy has revolutionized biological research by enabling the study of biological functions down to the molecular scale. Despite profound technological developments, ... -
Functional and Structural Characterization of the DEAH-box Helicase Prp43
(2022-11-24)RNA helicases of the DEAH-box family fulfill essential functions in various aspects of RNA metabolism by reorganizing structured RNAs and RNPs through ATP-dependent motility in 3’ to 5’ direction along single-strands. Prp43 ... -
Prenatal maternal stress effects in wild Assamese macaques (Macaca assamensis)
(2022-11-22)Across mammals, adverse conditions experienced during specific ontogenetic sensitive periods can have persisting effects on neurodevelopment, acquisition of cognitive and motoric skills, immune function, and systemic ... -
Cystic Fibrosis as a model use case for implementing cell based disease models in systems medicine
(2022-11-22)In the last two decades, tremendous progress has been made in producing large amounts of biological and biomedical data in a time- and cost-effective manner. Along with the increasing amount of data has come the requirement ... -
Droplet-based giant unilamellar vesicles as a tool for pore-spanning membrane preparation and transmembrane protein reconstitution
(2022-11-22)Model membranes represent a central tool to decipher complex processes of living cells. Giant unilamellar vesicles (GUVs) are of particular interest as they are cell-like in size, observable with optical microscopy and ... -
Dynamics and self-organization of membrane-bound minimal actin and actomyosin cortices based on ezrin-PtdIns[4,5]P2 linkage
(2022-11-22)The cellular cortex is a thin actin layer attached to the cytoplasmatic plasma membrane leaflet of mammalian cells. Through a complex interaction with hundreds of actin binding proteins (ABPs), controlling e.g. the cortex ... -
Reconstructing the electrical dynamics on the heart
(2022-11-09)The heart is an electro-mechanical system. In 2010 about 4.25 million people died from cardiac arrhythmias. Immediate treatment in case of fibrillation is to shock the heart electrically with high energy to reset the ... -
Modelling the Dynamics of Actomyosin Networks
(2022-11-04)In this dissertation, a new framework called bead-state model (BSM) for computer simulations of actin networks is presented, and its scientific validity and its usability and flexibility is demonstrated in three ... -
