Activated protein C (APC) is an anticoagulant protease that initiates cell signaling via protease-activated receptor 1 (PAR1) to regulate vascular integrity and inflammatory response. In this study, a recombinant APC variant (APC(N329Q)) mimicking the naturally occurring APC-β plasma glycoform was found to exhibit superior PAR1 proteolysis at a cleavage site that selectively mediates cytoprotec...

Microtubules and their associated proteins (MAPs) underpin the polarity of specialised cells. Adenomatous polyposis coli (APC) is one such MAP with a multifunctional agenda that requires precise intracellular localisations. Although APC has been found to associate with kinesin-2 subfamily members, the exact mechanism for the peripheral localization of APC remains unclear. Here we show that the ...

The antithrombotic plasma enzyme, activated protein C (APC), may play a role in thrombolysis. In vitro, acceleration of clot lysis by APC depends on its ability to inhibit the activation of prothrombin. The effect of APC on the assembly and dispersion of fibrin network was studied using turbidimetry, plasmin digestion of fibrin, and electron microscopy of plasma clots. The addition of APC befor...

Germline mutations of the APC gene are responsible for familial adenomatous polyposis, an autosomal dominant inherited predisposition to colorectal tumors. Mutation of the APC gene is also an early, if not initiating, event for sporadic colorectal tumorigenesis. In both cases, almost all of the currently identified mutations of APC result in the truncation of the protein. In this study, we demo...

PURPOSE Hypertrophy and hyperplasia of the retinal pigment epithelium (RPE) is associated with an inherited predisposition to human familial adenomatous polyposis coli, suggesting that expression of the adenomatous polyposis coli (APC) tumor suppressor may regulate RPE proliferation/differentiation. Distinctive APC isoforms exist in different cell types due to alternative splicing of the APC tr...

statement of problem: recent literatures show that accelerated portland cement (apc) and calcium hydroxide ca (oh) 2 may have the potential to promote the bone regeneration. however, certain clinical studies reveal consistency of ca (oh) 2, as one of the practical drawbacks of the material when used alone. to overcome such inconvenience, the combination of the ca (oh) 2 with a bone replacement ...

Mutation of tumor suppressor adenomatous polyposis coli (APC) initiates most colorectal cancers and chronic colitis increases risk. APC is a nucleo-cytoplasmic shuttling protein, best known for antagonizing Wnt signaling by forming a cytoplasmic complex that marks β-catenin for degradation. Using our unique mouse model with compromised nuclear Apc import (Apc(mNLS)), we show that Apc(mNLS/mNLS)...

Loss-of-function mutations in human adenomatous polyposis coli (APC) lead to multiple colonic adenomatous polyps eventually resulting in colonic carcinoma. Similarly, heterozygous mice carrying defective APC (apc(Min/+)) suffer from intestinal tumours. The animals further suffer from anaemia, which in theory could result from accelerated eryptosis, a suicidal erythrocyte death triggered by enha...

The role of adenomatous polyposis coli (APC) has been implicated in various cellular functions including cell migration, cell-cell adhesion, cell cycle control, chromosomal segregation and apoptosis. Recently, we discovered a novel role of APC in DNA base excision repair (BER) and showed that APC interacts with DNA polymerase beta (Pol-beta) and flap endonuclease 1 and interferes long-patch bas...

Activated protein C (APC) has both anticoagulant activity and direct cell-signaling properties. APC has been reported to promote cancer cell migration/invasion and to inhibit apoptosis and therefore may exacerbate metastasis. Opposing these activities, APC signaling protects the vascular endothelial barrier through sphingosine-1-phosphate receptor-1 (S(1)P(1))activation, which may counteract ca...
