Wireless ATM networks require efficient mobility management to cope with frequent mobile handoff and rerouting of connections. Although much attention has been given in the literature to network architecture design to support wide-area mobility in public ATM networks, little has been done to the important issue of user mobility estimation and prediction to(More)
Mitochondrial morphology is controlled by two opposing processes: fusion and fission. Drp1 (dynamin-related protein 1) and hFis1 are two key players of mitochondrial fission, but how Drp1 is recruited to mitochondria and how Drp1-mediated mitochondrial fission is regulated in mammals is poorly understood. Here, we identify the vertebrate-specific protein(More)
Thioredoxin 1 (Trx1) facilitates the reduction of signaling molecules and transcription factors by cysteine thiol-disulfide exchange, thereby regulating cell growth and death. Here we studied the molecular mechanism by which Trx1 attenuates cardiac hypertrophy. Trx1 upregulates DnaJb5, a heat shock protein 40, and forms a multiple-protein complex with(More)
BACKGROUND Among the different types of breast cancer, basal-like breast cancer (BLBC) has an extremely poor prognosis due to its high rate of recurrence and metastasis. The present study aimed to investigate the correlation between the expression of Slug, E-cadherin, and vimentin, and the clinicopathological characteristics and prognosis of patients with(More)
Here we show that Mst1, a proapoptotic kinase, impairs protein quality control mechanisms in the heart through inhibition of autophagy. Stress-induced activation of Mst1 in cardiomyocytes promoted accumulation of p62 and aggresome formation, accompanied by the disappearance of autophagosomes. Mst1 phosphorylated the Thr108 residue in the BH3 domain of(More)
Transnitrosylation and denitrosylation are emerging as key post-translational modification events in regulating both normal physiology and a wide spectrum of human diseases. Thioredoxin 1 (Trx1) is a conserved antioxidant that functions as a classic disulfide reductase. It also catalyzes the transnitrosylation or denitrosylation of caspase 3 (Casp3),(More)
The association between obstructive sleep apnea (OSA) and atrial fibrillation (AF) is strong and is now well established. However, studies on the role of OSA on AF recurrence after catheter ablation have yielded conflicting results. The aim of the present study was to investigate the role of OSA on AF recurrence after catheter-based pulmonary vein(More)
The microbial community in a full-scale anaerobic digester (2300m3) treating industrial food waste in the Kyoto Eco-Energy Project was analyzed using terminal restriction fragment length polymorphism for eubacterial and archaeal 16S rRNA genes. Both thermophilic and mesophilic sludge of treated swine waste were seeded to the digestion tank. During the(More)
The Hippo pathway, evolutionarily conserved from flies to mammals, promotes cell death and inhibits cell proliferation to regulate organ size. The core component of this cascade, Mst1 in mammalian cells, is sufficient to promote apoptosis. However, the mechanisms underlying both its activation and its ability to elicit cell death remain largely undefined.(More)
