Generation of a genetically-modified induced pluripotent stem cell line harboring a Noonan syndrome-associated gene variant MRAS p.G23V

Authors Busley AV, Cyganek L Journal Stem Cell Research Citation Stem Cell Res. 2023 Jun;69:103108. Abstract Patients harboring causative gene variants in RAS GTPase MRAS develop Noonan syndrome and early-onset hypertrophic cardiomyopathy. Here, we describe the generation of a human iPSC line harboring the Noonan syndrome-associated MRAS p.G23V variant by

Influence of phosphorylation on intermediate filaments

Authors Kraxner J, Köster S Journal Biological Chemistry Citation Biol Chem. 2023 Apr 20. Abstract The cytoskeleton of eukaryotes consists of actin filaments, microtubules and intermediate filaments (IF). IFs, in particular, are prone to pronounced phosphorylation, leading to additional charges on the affected amino acids. In recent years, a variety

Signatures of heterogeneity in the statistical structure of target state aligned ensembles

Authors Lenner N, Häring M, Eule S, Großhans J, Wolf F Journal ArXiv Citation arXiv:2304.09719. Abstract Finite time convergence to functionally important target states is a key component of many biological processes. We previously found that the terminal approach phase of such dynamics exhibits universal types of stochastic dynamics that
