Assessing dystrophies and other muscle diseases at the nanometer scale by atomic force microscopy

Harald Brune, Andrzej Kulik, Nicolas Mermod, Giovanni Dietler, Guillaume Witz, Stefania Puttini

Aim: Atomic force microscopy nanoindentation of myofibers was used to assess and quantitatively diagnose muscular dystrophies from human patients. Materials & methods: Myofibers were probed from fresh or frozen muscle biopsies from human dystrophic patient ...

MAR-mediated integration of plasmid vectors for in vivo gene transfer and regulation

Andrzej Kulik, Nicolas Mermod, Damien Saugy, Stefania Puttini, Déborah Ley

Background: The in vivo transfer of naked plasmid DNA into organs such as muscles is commonly used to assess the expression of prophylactic or therapeutic genes in animal disease models. Results: In this study, we devised vectors allowing a tight regulatio ...

Intracellular nanomanipulation by a photonic-force microscope with real-time acquisition of a 3D stiffness matrix

László Forró, Gérard Gremaud, Andrzej Kulik, Philippe Thévenaz, Michaël Unser, Giovanni Dietler, Stefania Puttini, Sylvia Jeney, Elena Bertseva, Amardeep Singh

A traditional photonic-force microscope (PFM) results in huge sets of data, which requires tedious numerical analysis. In this paper, we propose instead an analog signal processor to attain real-time capabilities while retaining the richness of the traditi ...

Gene-mediated Restoration of Normal Myofiber Elasticity in Dystrophic Muscles

Andrzej Kulik, Nicolas Mermod, Damien Saugy, Stefania Puttini

Dystrophin mediates a physical link between the cytoskeleton of muscle fibers and the extracellular matrix, and its absence leads to muscle degeneration and dystrophy. In this article, we show that the lack of dystrophin affects the elasticity of individua ...
