3D Neuronal Cell Culture Modeling Based on Highly Porous Ultra-High Molecular Weight Polyethylene.

Cell culturing methods in its classical 2D approach have limitations associated with altered cell morphology, gene expression patterns, migration, cell cycle and proliferation. Moreover, high throughput drug screening is mainly performed on 2D cell cultures which are physiologically far from proper cell functions resulting in inadequate hit-compounds which subsequently fail. A shift to 3D culturing protocols could solve issues with altered cell biochemistry and signaling which would lead to a proper recapitulation of physiological conditions in test systems.

FUS(1-359) transgenic mice as a model of ALS: pathophysiological and molecular aspects of the proteinopathy.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder that leads to the eventual death of motor neurons. Described cases of familial ALS have emphasized the significance of protein misfolding and aggregation of two functionally related proteins, FUS (fused in sarcoma) and TDP-43, implicated in RNA metabolism. Herein, we performed a comprehensive analysis of the in vivo model of FUS-mediated proteinopathy (ΔFUS(1-359) mice).
