SUMO (small ubiquitin-like modifier)/Smt3 (suppressor of mif two) is a member of the ubiquitin-related protein family and is known to conjugate with many proteins. In the sumoylation pathway, SUMO/Smt3 is transferred to substrate lysine residues through the thioester cascade of E1 (activating enzyme) and E2 (conjugating enzyme), and E3 (SUMO ligase)(More)
BACKGROUND Internet peer support groups for depression are becoming popular and could be affected by an increasing number of social network services (SNSs). However, little is known about participant characteristics, social relationships in SNSs, and the reasons for usage. In addition, the effects of SNS participation on people with depression are rather(More)
The Smt3 (SUMO) protein is conjugated to substrate proteins through a cascade of E1, E2, and E3 enzymes. In budding yeast, the E3 step in sumoylation is largely controlled by Siz1p and Siz2p. Analysis of Siz- cells shows that SUMO E3 is required for minichromosome segregation and thus has a positive role in maintaining the fidelity of mitotic transmission(More)
SUMO is a posttranslational modifier that can modulate protein activities, interactions, and localizations. As the GFP-Smt3p fusion protein has a preference for subnucleolar localization, especially when deconjugation is impaired, the nucleolar role of SUMO can be the key to its biological functions. Using conditional triple SUMO E3 mutants, we show that(More)
SUMO/Smt3, a ubiquitin-like modifier, is known to conjugate other proteins and modulate their functions in various processes. Recently, Ull1/Siz1 was discovered as a novel PIAS-type E3 required for septin sumoylation in yeast. We demonstrate here that the second PIAS-type Nfi1/Siz2 is also a SUMO ligase. It interacted with Smt3, SUMO/Smt3 conjugating enzyme(More)
Accumulation of protein-bound uraemic toxins (PBUTs) is one of the reasons for the development of uraemia-related complications including cardiovascular disease; however, conventional haemodialysis is limited in its ability to remove PBUTs. We aimed to examine whether the oral charcoal adsorbent AST-120 has an additive effect on PBUT removal in(More)
We performed a retrospective case-series study of patients with influenza A (H5N1) admitted to the National Institute of Infectious and Tropical Diseases in Hanoi, Vietnam, from January 2004 through July 2005 with symptoms of acute respiratory tract infection, a history of high-risk exposure or chest radiographic findings such as pneumonia, and positive(More)
BACKGROUND/AIMS Given the clear benefits of mortality reduction observed for most beta-blockers in clinical trials, they are relatively underused in hemodialysis patients. Since the outcomes associated with the use of beta-blockers are not fully known, we investigated their effect on mortality among a cohort of hemodialysis patients. METHODS Data were(More)
BACKGROUND Whilst being obese is associated with increased mortality, less is known about the relationship between body weight and health-related quality of life (HRQOL). We aimed to examine this relationship in the general Japanese population, focusing on both underweight and overweight individuals. METHODS We cross sectionally analyzed data from the(More)
OBJECTIVES Although central blood pressure (BP) is considered to be more closely associated with large arterial remodeling and cardiovascular outcomes than brachial BP, few studies have investigated these associations with changes in small arteries. As morphological changes in retinal vessels might be associated with cardiovascular outcomes, we conducted a(More)
