Cancer and dendritic cells recognize and migrate toward chemokines secreted from lymphatics and use this mechanism to invade the lymphatic system, and cancer cells metastasize through it. The lymphatic-secreted chemokine ligand CCL21 has been identified as a key regulatory molecule in the switch to a metastatic phenotype in melanoma and breast cancer cells.(More)
Short peptide sequences that are able to transport molecules across the cell membrane have been developed as tools for intracellular delivery of therapeutic molecules. This work describes a novel family of cell-penetrating peptides named Vectocell peptides [also termed DPVs (Diatos peptide vectors)]. These peptides, originating from human heparin binding(More)
Improvement in the therapeutic index of doxorubicin, a cytotoxic molecule, has been sought through its chemical conjugation to short (15-23 amino acid) peptide sequences called Vectocell peptides. Vectocell peptides are highly charged drug delivery peptides and display a number of characteristics that make them attractive candidates to minimize many of the(More)
Endothelin-converting enzyme (ECE)-1 is a membrane-bound metallopeptidase of the neprilysin (NEP) family. ECE-1 is responsible for the conversion of inactive big-endothelins into active endothelins. Three different isoforms of human ECE-1 (ECE-1a, ECE-1b and ECE-1c) have been identified. They differ in their N-terminal cytosolic regions, have distinct(More)
PURPOSE Fluorescence-guided surgery (FGS) provides surgeons with new opportunities to improve real-time cancer nodule detection and tumor margin visualization. Currently, the most important challenge in this field is the development of fluorescent dyes that specifically target tumors. We developed, characterized and evaluated SGM-101, an innovative(More)
In order to compare the trafficking of proteins with different membrane anchors, we have constructed and expressed three different recombinant forms of neutral endopeptidase (NEP) in MDCK cells. The wild type form of NEP (WT-NEP) is attached to the plasma membrane by a single N-terminal membrane spanning domain, whereas the(More)
