Shigella infection, the cause of bacillary dysentery, induces caspase-1 activation and cell death in macrophages, but the precise mechanisms of this activation remain poorly understood. We...
Na+ more strongly inhibits DNA compaction by spermidine (3+) than K+ (2006)
Hibino, Kumiko, Yoshikawa, Yuko, Murata, Shizuaki, Saito, Takuya, Zinchenko, Anatoly A., Yoshikawa, Kenichi
The protective effects of alkali metal ions (Li+, Na+, K+, Rb+ and Cs+) against spermidine-induced DNA compaction were studied using single-molecule observations. We found that all alkali metal salts...

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...
Folding transition of DNA depending on ionic environments (2004)
Hibino, Kumiko, Yoshikawa, Yuko, Murata, Shizuaki
We examined the effect of monovalent salts, NaCl and KCl, on spermidine-induced DNA compaction using fluorescence microscopy. By increasing concentrations of salts, unfolding process of compacted...
Salt-dependent folding of long duplex DNA by histone H 1 (2000)
Yoshikawa, Yuko, Kanbe, Toshio
It is found that T4 phage DNA complexed with histone H1 assembled into a string-of-bead structure, when the complex is prepared by a gentle diluting procedure from a high salt solution (2 M NaCI) to...
Folding transition of long duplex DNA from mammalian cells (1999)
Yoshikawa, Yuko, Kanbe, Toshio, Yoshikawa, Kenichi
Conformational change in individual giant DNAs from pig liver is studied by use of fluorescence microscopy. With the addition of spermidine (a trivalent amine), each DNA chains undergo abrupt...

ATP-Induced Shrinkage of DNA with MukB Protein and the MukBEF Complex of Escherichia coli▿
Chen, Ning, Zinchenko, Anatoly A., Yoshikawa, Yuko, Araki, Sumiko, Adachi, Shun, Yamazoe, Mitsuyoshi, ...
Fluorescence microscopic observation of individual T4 DNA molecules revealed that the MukBEF complex (bacterial condensin) and its subunit, the MukB (a member of the SMC [structural maintenance of...
