Osmotic deflation of vesicles enclosing two liquid phases can lead to bulging of one of the phases from the vesicle body. This budding process is preceded by a complete to partial wetting transition of one of the liquid phases on the membrane and depends on the membrane tensions and the tension of the interface between the enclosed liquid phases. These tensions dominate in different morphology ...

Background/Aim. The histological phenomenon of tumor budding is being recognized as an important determinant disease progression and poor prognosis in various types carcinoma. We aimed to evaluate the clinicopathological significance adenocarcinoma lung. Methods. study included 114 patients operatively treated for lung a one-year period. Microscopic analysis routine slides was performed establi...

Ebola virus budding is mediated by two proline-rich motifs, PPxY and PTAP, within the viral matrix protein VP40. We have previously shown that a Nedd4-like protein BUL1, but not Nedd4, positively regulates budding of type D retrovirus Mason-Pfizer monkey virus (J. Yasuda, E. Hunter, M. Nakao, and H. Shida, EMBO Rep. 3:636-640, 2002). Here, we report that the cellular E3 ubiquitin ligase Nedd4 r...

Budding yeast, which undergoes polarized growth during budding and mating, has been a useful model system to study cell polarization. Bud sites are selected differently in haploid and diploid yeast cells: haploid cells bud in an axial manner, while diploid cells bud in a bipolar manner. While previous studies have been focused on the molecular details of the bud site selection and polarity esta...

The aim of this study is trying to describe more details of superior mesenteric artery margin in pancreaticoduodenectomy for pancreatic ductal adenocarcinoma, to evaluate biological and prognostic implications of tumor budding in this margin, and to provide more evidence for evaluation of R0 surgery in pancreaticoduodenectomy. 46 patients in 5-years period are included in this study. Immunochem...

In this study, we have identified a novel Nedd4-like ubiquitin ligase, BUL1, as the host factor involved in budding of type D retrovirus Mason-Pfizer monkey virus (M-PMV). Overexpression of BUL1 enhanced virus particle release, while a BUL1 mutant in which a W to G substitution was introduced into a WW domain, W791G, lost the ability to bind to the viral Gag protein and abolished its ability to...

The matrix protein VP40 of Marburg virus promotes the formation and release of virus-like particles (VLPs). Marburg virus VP40 interacts with cellular Tsg101 via its L domain motif; however, mutation of this motif does not affect VLP budding or the accumulation of VP40 in multivesicular bodies (MVBs), which are platforms for virus particle formation. To identify regions of Marburg virus VP40 th...

Viral matrix proteins of several enveloped RNA viruses play important roles in virus assembly and budding and are by themselves able to bud from the cell surface in the form of lipid-enveloped, virus-like particles (VLPs). Three motifs (PT/SAP, PPxY, and YxxL) have been identified as late budding domains (L-domains) responsible for efficient budding. L-domains can functionally interact with cel...

Budding marks initiation of cell division in Saccharomyces cerevisiae. Consequently, cell cycle progression can be monitored by the fraction of budded cells (budding index) in a proliferating cell population. We determined the budding index of a large collection of deletion strains, to systematically identify genes involved in cell cycle progression.
