The anaphase-promoting complex/cyclosome (APC/C) is a large multimeric cullin-RING E3 ubiquitin ligase that orchestrates cell-cycle progression by targeting cell-cycle regulatory proteins for destruction via the ubiquitin proteasome system. The APC/C assembly comprises two scaffolding subcomplexes: the platform and the TPR lobe that together coordinate the juxtaposition of the catalytic and sub...

The Open Access (OA) publishing model that is based on article processing charges (APC) often associated with the potential for more transparency regarding expenditures publications. However, extent to which can be achieved depends not least completeness of data in APC monitoring systems. This investigates two blind spots largest collection payment information, OpenAPC. It aims identify likely ...

Truncation mutations in the adenomatous polyposis coli protein (APC) are responsible for familial polyposis, a form of inherited colon cancer. In addition to its role in mediating beta-catenin degradation in the Wnt signaling pathway, APC plays a role in regulating microtubules. This was suggested by its localization to the end of dynamic microtubules in actively migrating areas of cells and by...

The tumor suppressor protein adenomatous polyposis coli (APC) regulates cell protrusion and cell migration, processes that require the coordinated regulation of actin and microtubule dynamics. APC localizes in vivo to microtubule plus ends and actin-rich cortical protrusions, and has well-documented direct effects on microtubule dynamics. However, its potential effects on actin dynamics have re...

Inactivation of the adenomatous polyposis coli (APC) gene is a major initiating event in colorectal tumorigenesis. Most of the mutations in APC generate premature stop codons leading to truncated proteins that have lost beta-catenin binding sites. APC-free beta-catenin stimulates the Wnt signaling pathway, leading to active transcription of target genes. In the current study, we describe a nove...

Recent studies have suggested that APC loss alone may be insufficient to promote aberrant Wnt/beta-catenin signalling. Our aim was to comprehensively characterize Wnt signalling components in a set of APC-associated familial adenomatous polyposis (FAP) tumours. Sixty adenomas from six FAP patients with known pathogenic APC mutations were included. Somatic APC and KRAS mutations, beta-catenin im...

BACKGROUND The adenomatous polyposis coli (APC) protein is an important tumour suppressor in the colon. It promotes the destabilisation of free cytoplasmic beta-catenin (the vertebrate homologue of the Drosophila protein Armadillo), a critical effector of the Wnt signalling pathway. The beta-catenin protein is also a component of adherens junctions, linking these to the actin cytoskeleton. In D...

Adenomatous polyposis coli protein (APC) is a well-characterized tumor suppressor protein [1] [2] [3]. We previously showed that APC tagged with green fluorescent protein (GFP) in Xenopus A6 epithelial cells moves along a subset of microtubules and accumulates at their growing plus ends in cell extensions [4]. EB1, which was identified as an APC-binding protein by yeast two-hybrid analysis [5],...

The key effector molecule of the natural protein C pathway, activated protein C (aPC), exerts pleiotropic effects on coagulation, fibrinolysis, and inflammation. Coagulation-independent cell signaling by aPC appears to be the predominant mechanism underlying its highly reproducible therapeutic efficacy in most animal models of injury and infection. In this study, using a mouse model of Staphylo...

940 INTRODUCTION A nonsense mutation in the tumour suppressor adenomatous polyposis coli (APC) is sufficient to cause colorectal cancer in humans and animal models (Nandan and Yang, 2010; Kwong and Dove, 2009). Hereditary and sporadic cancers commonly carry nonsense mutations in APC that result in the expression of Nterminal fragments of the APC protein, so that the protein lacks the more C-ter...
