We have recently reported that cell-penetrating peptides (CPPs) and novel chimeric peptides containing CPP (referred as B peptide) and muscle-targeting peptide (referred as MSP) motifs significantly improve the systemic exon-skipping activity of morpholino phosphorodiamidate oligomers (PMOs) in dystrophin-deficient mdx mice. In the present study, the general mechanistic significance of the chim...

To achieve mitochondrial therapy, we previously reported on the use of an octaarginine (R8) modified Dual Function (DF)-MITO-Porter for delivering molecules to mitochondria in living cells. In this study, using isolated mitochondria, homogenates and living cells, we evaluated the utility of mitochondrial targeting functional peptides as a ligand for delivering carriers. The S2 peptide modified ...

introduction: antimicrobial peptides as the body's defense strategy play an important role in resistance against infection of microorganism. these peptides are able to modulate the immune and inflammatory processes through the production of defensive molecules. therefore, the modulatory effects of brevinin-2r, an antimicrobial peptide extracted from the skin of the frog (rana ridibunda), w...

A functional interaction between the signal sequence and the translation apparatus which may serve as a first step in chain targeting to the membrane is described. To this end, we exploited the powerful technique of molecular cloning in a procaryotic system and the well characterized translocation system of mammalian endoplasmic reticulum. The signal peptide of subunit B of the heat labile ente...

It is well known that Arginine-Glycine-Aspartic acid (RGD) and Asparagine-Glycine-Arginine (NGR) peptides preferentially bind to integrin receptors and aminopeptidase Nrespectively and these two receptors play important roles in angiogenesis. Therefore ketoprofenas a non-selective cox Inhibitor was conjugated with linear RGD and NGR to take advantageof targeting capability of these two motifs a...

Effective and specific targeting of nanoparticles is of paramount importance in the fields of targeted therapeutics and diagnostics. In the current study, we investigated the targeting efficacy of nanoparticles that were functionalized with two angiogenesis-specific targeting ligands, an alpha(v)beta(3) integrin-specific and a galectin-1-specific peptide. We show in vitro, using optical techniq...

Among gene delivery systems, peptide-based carriers have received significant attention because of their selectivity, biocompatibility, and biodegradability. Since cellular membranes function as a barrier toward exogenous molecules, cell-penetrating peptides (CPPs), which are usually cationic and/or amphiphilic, can serve efficient to deliver cargo into the cytosol. Here, we examined interactio...

Background and objectives: Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) inhibition results in an increase in apoptosis. It has been demonstrated that NF-κB subunit p65 phosphorylation at the IκB kinase phosphorylation site serine 536 (Ser536) is essential for the NF-κB nuclear translocation and activation. Therefore, NF-κB can be downregulated by suppressing its phosph...
