To understand the DNA recognition mechanism of zinc finger motifs of transcription factor Sp1, we have determined the solution structure of DNA-binding domain of the Sp1 by solution NMR techniques. The DNA-binding domain of Sp1 consists of three Cys(2)His(2)-type zinc finger motifs. They have typical betabetaalpha zinc finger folds and relatively random(More)
OBJECTIVE The aim of this study was to elucidate the clinicopathological features and prognosis of mucinous cystic neoplasms (MCNs). MATERIALS AND METHODS We performed a multi-institutional, retrospective study on a collected series of patients with MCN pathologically defined by ovarian-type stroma. Clinicopathological features and prognosis were(More)
OBJECTIVES Endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) has recently been reported as an alternative to percutaneous transhepatic biliary drainage (PTBD) in cases of biliary obstruction, when endoscopic biliary drainage (EBD) is unsuccessful. However, prospective studies of EUS-CDS have not yet been performed. We conducted a prospective(More)
Weak acids such as acetate and benzoate, which partially collapse the transmembrane proton gradient, not only mediate pH taxis but also impair the motility of Escherichia coli and Salmonella at an external pH of 5.5. In this study, we examined in more detail the effect of weak acids on motility at various external pH values. A change of external pH over the(More)
This study presents the crystal structure of domain I of the Escherichia coli ribosome recycling factor (RRF) bound to the Deinococcus radiodurans 50S subunit. The orientation of RRF is consistent with the position determined on a 70S-RRF complex by cryoelectron microscopy (cryo-EM). Alignment, however, requires a rotation of 7 degrees and a shift of the(More)
Organotin compounds such as triphenyltin (TPT) and tributyltin (TBT) act as endocrine disruptors through the peroxisome proliferator-activated receptor γ (PPARγ) signaling pathway. We recently found that TPT is a particularly strong agonist of PPARγ. To elucidate the mechanism underlying organotin-dependent PPARγ activation, we here analyzed the(More)
