RhoGEF Solo regulates cell density-dependent keratin remodeling and desmosome maturation

Ukyo Kawasaki, Riku Maruta, Kensaku Mizuno, Shuhei Chiba, Kazumasa Ohashi

This study shows that Solo regulates keratin-DSM interactions and DSM maturation in response to cell density through RhoGEF activity and actin remodeling.

Density-Dependent Rearrangement of Desmoplakin in Epithelial Junctions: Insights from Expansion Microscopy

Ukyo Kawasaki, Yusuke Arakawa, Tetsuhisa Otani, Kazumasa Ohashi, Shuhei Chiba

The paper uses expansion microscopy to show that epithelial cell density changes the organization of desmoplakin in junctions, with increased C-terminal spacing in confluent monolayers.

Actin cytoskeletal remodeling requires the interaction between Solo and LARG in response to substrate stiffness

Aoi Kunitomi, Yusuke Toyofuku, Shuhei Chiba, Nahoko Higashitani, Atsushi Higashitani, Shinichi Sato, Kensaku Mizuno, Kazumasa Ohashi

The paper investigates the interaction between Solo and LARG in response to substrate stiffness and finds that this interaction is required for actin polymerization.
