Initial high-resolution microscopic mapping of active and inactive regulatory sequences proves non-random 3D arrangements in chromatin domain clusters

Background: The association of active transcription regulatory elements (TREs) with DNAse I hypersensitivity (DHS[+]) and an open local chromatin configuration has long been known. However, the 3D topography of TREs within the nuclear landscape of …

Maximum Entropy Approach in Dynamic Contrast-Enhanced Magnetic Resonance Imaging

Quantitative analyses of the 3D nuclear landscape recorded with super-resolved fluorescence microscopy

Recent advancements of super-resolved fluorescence microscopy have revolutionized microscopic studies of cells, including the exceedingly complex structural organization of cell nuclei in space and time. In this paper we describe and discuss tools …

Boosting in Nonlinear Regression Models with an Application to DCE-MRI Data

For the statistical analysis of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) data, compartment models are a commonly used tool. By these models, the observed uptake of contrast agent in some tissue over time is linked to physiologic …

Stage-dependent remodeling of the nuclear envelope and lamina during rabbit early embryonic development

Utilizing 3D structured illumination microscopy, we investigated the quality and quantity of nuclear invaginations and the distribution of nuclear pores during rabbit early embryonic development and identified the exact time point of nucleoporin 153 …

Bayesian mixed-effects model for the analysis of a series of FRAP images

The binding behavior of molecules in nuclei of living cells can be studied through the analysis of images from fluorescence recovery after photobleaching experiments. However, there is still a lack of methodology for the statistical evaluation of …

Remodeling of the Nuclear Envelope and Lamina during Bovine Preimplantation Development and Its Functional Implications

The present study demonstrates a major remodeling of the nuclear envelope and its underlying lamina during bovine preimplantation development. Up to the onset of major embryonic genome activation (MGA) at the 8-cell stage nuclei showed a non-uniform …
