Direct attack to genomic DNA by reactive oxygen species causes various types of lesions, including base modi. cations and strand breaks. The most significant lesion is considered to be an unrepaired...
Hydrodynamic radius of circular DNA is larger than that of linear DNA (2006)
Araki, Sumiko, Nakai, Tonau, Hizume, Kohji, Takeyasu, Kunio, Yoshikawa, Kenichi
It is generally accepted that linear polymers are larger, such as with regard to the end-to-end distance and gyration radius, than the corresponding circular polymers. We measured the Brownian motion...

Phase Transition in Reconstituted Chromatin (2004)
Nakai, Tonau, Hizume, Kohji, Yoshimura, Shige. H., Takeyasu, Kunio, Yoshikawa, Kenichi
By observing reconstituted chromatin by fluorescence microscopy (FM) and atomic force microscopy (AFM), we found that the density of nucleosomes exhibits a bimodal profile, i.e., there is a large...

A small container of several to a few hundred µm3 (i.e. bacterial cells and eukaryotic nuclei) contains extremely long genomic DNA (i.e. mm and m long, respectively) in a highly organized fashion....
Condensin but not cohesin SMC heterodimer induces DNA reannealing through protein–protein assembly
Sakai, Akiko, Hizume, Kohji, Sutani, Takashi, Takeyasu, Kunio, Yanagida, Mitsuhiro
Condensin and cohesin are chromosomal protein complexes required for chromosome condensation and sister chromatid cohesion, respectively. They commonly contain the SMC (structural maintenance of...
