Native chemical ligation (NCL) allows the synthesis of proteins and peptides with excellent efficiency, starting from a mixture unprotected short peptide fragments. The chemo- regioselectivity NCL provide access to functional biomacromolecules such as without protection–deprotection strategies under mild conditions. In contrast, less progress has been made in non-natural polymer conjugation. Me...

Nucleolin (NCL) is highly expressed in several types of cancer and represents an interesting therapeutic target. It is expressed at the plasma membrane of tumor cells, a property which is being used as a marker for several human cancer including glioblastoma. In this study we investigated targeting NCL as a new therapeutic strategy for the treatment of this pathology. To explore this possibilit...

The ability to associate stimuli across time and sensory modalities endows animals and humans with many of the complex, learned behaviors. For successful performance, associations need to be retrieved from long-term memory and maintained active in working memory. We investigated how this is accomplished in the avian brain. We trained carrion crows (Corvus corone) to perform a bimodal delayed pa...

AS1411 is a G-rich aptamer that forms a stable G-quadruplex structure and displays antineoplastic properties both in vitro and in vivo. This oligonucleotide has undergone phase 2 clinical trials. The major molecular target of AS1411 is nucleolin (NCL), a multifunctional nucleolar protein also present in the cell membrane where it selectively mediates the binding and uptake of AS1411. Cell-surfa...

AS1411 binds nucleolin (NCL) and is the first oligodeoxynucleotide aptamer to reach phase I and II clinical trials for the treatment of several cancers. However, the mechanisms by which AS1411 targets and kills glioma cells and tissues remain unclear. Here we report that AS1411 induces cell apoptosis and cycle arrest, and inhibits cell viability by up-regulation of p53 and down-regulation of Bc...

The neuronal ceroid lipofuscinoses (NCLs, also known collectively as Batten disease) are a group of lysosomal storage disorders characterized by the accumulation of autofluorescent storage material in the brain and other tissues. A number of genes underlying various forms of NCL have been cloned, but the basis for the neurodegeneration in any of these is unknown. High levels of dolichol pyropho...

Liposomes have become popular drug delivery vehicles and have more recently also been applied as contrast agents for molecular imaging. Most current methods for functionalization of liposomes with targeting proteins rely on reactions of amine or thiol groups at the protein exterior, which generally result in nonspecific conjugation at multiple sites on the protein. In this study, we present nat...

Neuronal ceroid lipofuscinoses (NCLs) are autosomal recessive progressive encephalopathies caused by mutations in at least 14 different genes. Despite extensive studies performed in different NCL animal models, the molecular mechanisms underlying neurodegeneration in NCLs remain poorly understood. To model NCL in human cells, we generated induced pluripotent stem cells (iPSCs) by reprogramming ...

The Neuronal Ceroid Lipofuscinoses (NCLs) are the most common group of neurodegenerative disorders of childhood. While mutations in eight different genes have been shown to be responsible for these clinically distinct types of NCL, the NCLs share many clinical and pathological similarities. We have conducted an exhaustive Basic Local Alignment Search Tool (BLAST) analysis of the human protein s...

The massive and random deployment of Femto Base Stations (FBSs) by customers generates several technical challenges. This work investigates self-organization in an LTE femtocell network. Specifically, each FBS self-configures locally unique Physical Cell ID (PCI) and Neighbor Cell List (NCL). As more and more FBSs are being deployed, PCI reuse is inevitable, which aims to minimize cell ID colli...
