چکیده

Introduction Aiming to image the presence of specific mRNAs by MRI, we have developed two intracellular MR contrast agents (CA) composed of a Gd-DOTA complex, a peptide nucleic acid (PNA) sequence and a cell penetrating peptide. One (dsRed CA) was designed to bind to mRNA of dsRed (red fluorescent protein originating from Discosoma coral) by its complementary peptide nucleic acid (PNA) sequence, whereas the second one contained a nonsense sequence with no natural counterpart.

Synthesis and cellular uptake of a MR contrast agent coupled to an antisense peptide nucleic acid--cell- penetrating peptide conjugate.

In order to image mRNA transcription by in vivo magnetic resonance imaging (MRI), two intracellular MR contrast agents were developed, which are composed of a Gd-DOTA complex, a peptide nucleic acid (PNA) sequence and a cell-penetrating peptide. One was designed to bind to mRNA of dsRed (red fluorescent protein originating from Discosoma coral) by its PNA sequence, whereas the second one contai...

Cell-penetrating peptides and peptide nucleic acid-coupled MRI contrast agents: evaluation of cellular delivery and target binding.

Molecular imaging of cells and cellular processes can be achieved by tagging intracellular targets such as receptors, enzymes, or mRNA. Seeking to visualize the presence of specific mRNAs by magnetic resonance (MR) imaging, we coupled peptide nucleic acids (PNA) with gadolinium-based MR contrast agents using cell-penetrating peptides for intracellular delivery. Antisense to mRNA of DsRed2 prote...

Cellular Morphology and Immunologic Properties of Escherichia coli Treated With Antimicrobial Antisense Peptide Nucleic Acid

  Background & Objectives: Antisense peptide nucleic acids (PNA) that target growth essential genes show potent bactericidal properties without cell lysis. We considered the possibility that whether PNA treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to Dendritic cells (DCs). DCs are the most potent antigen presenting cells in th...

Antisense effect of pyrrolidine-based oxy-peptide nucleic acids in Escherichia coli.

To investigate the antisense effect of a pyrrolidine-based oxy-peptide nucleic acid (POPNA), we carried out the LacZ reporter assay using a 12-mer trans-l-POPNA conjugated with a cell-penetrating peptide (antisense reagent). The antisense effect of the conjugated POPNA (inhibition of LacZ activity) was comparable to that shown by a Nielsen-type peptide nucleic acid. Furthermore, the conjugated ...

Role of Cell-Penetrating Peptides in Intracellular Delivery of Peptide Nucleic Acids Targeting Hepadnaviral Replication

Peptide nucleic acids (PNAs) are potentially attractive antisense agents against hepatitis B virus (HBV), although poor cellular uptake limits their therapeutic application. In the duck HBV (DHBV) model, we evaluated different cell-penetrating peptides (CPPs) for delivery to hepatocytes of a PNA-targeting hepadnaviral encapsidation signal (ε). This anti-ε PNA exhibited sequence-specific inhibit...
