  • PNAs have potential uses as antisense molecules for the control of gene expression. Since they are capable of binding tightly to DNA and RNA targets thus preventing DNA transcription to RNA and RNA translation to protein. These molecules thus have two potential uses of commercial importance:
  • a signal peptide is a short-lived _V-terminal sequence found only on nascent proteins which are synthesised m the endoplasmic reticulum.
  • Signal peptides consist of three domains:
  • Synthetic peptides consisting of only the hydrophobic cores are typically insoluble m water.
  • the signal peptide sequence of Karposi syndrome-derived FGF as an example, we have modified these insoluble sequences by the addition of positively charged ammo acids (for example lysmes) , which have the effect of rendering them water soluble without compromising their ability to translocate across cellular membranes.

  • PNAs suffer from similar accessibility problems as phosphorothioates do, and passive diffusion of unmodified PNA across lipid membranes is not efficient ( ittung, P., et al . , 1995) .
  • a small number of native peptide sequences can translocate across membranes of living cells in an energy- independent and receptor- independent manner. These peptides have been used to import active cargo into the cell.

Unlike the antennapedia peptide, carboxyfluorescein-kFGF signal peptide-KKK does not remain membrane -bound as shown by the data presented in Figure 4.
  • oligonucleotide sequences or those in which the phosphodiester bonds are replaced with nuclease-resistant bonds may be conjugated to the kFGF-derived delivery system for intracellular delivery and subsequent specific blocking of gene translation or Rnase-targeted destruction of the mRNA in question.
  • nuclease-resistant bonds such as the phosphothiorates and the like
  • peptide nucleic acid sequences may be used, as m example 1.
  • PNA Peptide Nucleic Acid
  • Nuclear localisation signal (NLS) sequences such as are found on transcription factors like NF-kappaB may be conjugated to the kFGF-derived delivery system, as m Example 1. Intracellular delivery of NLS peptide sequences would act as 'bait' to selectively block the translocation of the selected transcription factor, thus preventing its action. In this way, genes under the control of the transcription factor could be identified on the basis of down regulated expression.
  • NLS Nuclear localisation signal
  • Signal transduction motifs such as phosphotyros e- containing peptide sequences (pYP's) act as docking sites for a large number of proteins.
  • Such signalling proteins contain domains that recognise (contextually) the phosphotyrosme residues and bind to them m a specific manner.
  • pYP's are recognised by SH-2 (Src- homology-2) domains and PTB (phosphotyrosme binding domains) .
  • Specificity is provided by short ammo acid sequences iV-and/or C-termmal of the phosphotyrosme.
  • Such peptide motifs could be conjugated to the kFGF peptide-de ⁇ ved delivery system as m Example 1, and could be used to mtracellularly deliver pYP's which would act as bait, thus allowing signal pathways to be 'interrogated'.
  • FIG. 6A The signal sequence of kFGF was modified to contain three lysmes at the C-termmal of the hydrophobic signal sequence. This procedure is illustrated m Figure 6A.
  • Figure 6A (I) shows the signal peptide with an attached reporter group.
  • Figure 6A Part II illustrates the addition of the t ⁇ -lysme extension to the C-termmal of the signal peptide sequence, thus providing three positive charges which aid solubility and cell permeability.
  • Figure 6A Part Illb the peptide nucleic acid forms part of the linear primary ammo acid sequence, with Part IV illustrating a t ⁇ -lysme C-termmal extension to the peptide nucleic acid sequence providing 3 positive charges and aiding solubility and cell permeability.
  • Part V of Figure 6A further shows a tri-lysyl extension at the N-termmal of the signal peptide which provides 3 positive charges aiding solubility and cell permeability.
  • the addition of the tri-lysyl extension proximal to the carboxyfluorescein reporter group enhances its fluorescence.
  • the peptide nucleic acid sequence initially forms part of the linear primary ammo acid sequence at the N- terminal of the original peptide, before a tri-lysyl extension is added to the N-termmal of the peptide nucleic acid extension.
  • This peptide therefore, can accommodate three PNAs, each bonded to a lysine epsilon amino group.
  • This can be extended using the Multiple Antigen Presentation (MAP) technology to present eight (or more) PNA' s on one kFGF signal sequence.
  • MAP Multiple Antigen Presentation
  • a 'lysine tree' constructed in this way accommodates eight copies of the same PNA, thus increasing the effective concentration delivered by each CPPI.
  • Part I An example of the addition of such a lysine tree is shown in Figure 6C Parts I -IV.
  • Part I a single lysine molecule added to the C-terminal of the kFGF signal peptide sequence allows the multiple PNA lysine tree to be added to the e-amino group of the lysine side chain.
  • a lysine molecule added to the N-terminal of the kFGF signal peptide sequence allows the multiple PNA lysine tree to be added to the e-amino group of the lysine side chain.
  • Part III of Figure 6C further shows that when a C- terminal tri-lysine extension is added to the signal peptide with N-terminal associated multiple PNA lysine tree, the 3 positive charges aid solubility and cell permeability of the molecule.
  • Part IV of Figure 6C add a tri-lysyl extension at the N-terminal of the signal peptide which is attached to the lysine group added to allow attachment of the multiple PNA lysine tree as originally illustrated in Figure 6C Part II.
  • the addition of the 3 positively charged molecules at this terminal of the molecule, proximal to the carboxyfluorescein reporter group enhances its fluorescence.
  • a carrier can be constructed containing three (or more) different PNAs directed towards different sites on the same target mRNA. This strategy has been termed 'molecular triangulation' (Branch, A.D. , 1998) .
  • Figure 6B illustrates this process of 'molecular triangulation' .
  • Figure 6B Part I shows the signal peptide with a C-terminal tri-lysyl extension which allows three different PNA sequences to be conjugated to the epsilon-amino groups of the three lysines.
  • Figure 6B Part III shows the addition of a further three lysines to the molecule of Part I, which adds three positive charges, which aid solubility and cell permeability.
  • Figure 6B Part III shows the addition of the tri-lysyl extension to the N-terminal of the molecule of Part I. Again the 3 positive charges aid the solubility and cell permeability of the molecule, which their proximal location to the carboxyfluorescein reporter group enhances its fluorescence.
  • Figure 6B Part IV, illustrates an N-terminal tri-lysyl extension added to the kFGF signal peptide sequence, which subsequently allows three different PNA sequences to be conjugated to the epsilon-amino groups of the lysines. Further, this molecule has 3 lysines added at the C- terminal to add positive charge which aid solubility and cell permeability.
  • Figure 6B Part V shows the signal peptide again with the three peptide nucleic acid associated tri-lysine extension at the N-terminal, but with the addition of the further 3 lysine groups also being made to the N-terminal where they will have the effect of aiding solubility and cell permeability, which also enhance the fluorescence of the carboxyfluorescein reporter group due to their proximity.
  • Lysine extensions comprising more or less than three lysine residues may also be useful to provide additional solubility and cell permeability.
  • the lysine extension may be provided next to a carboxyfluorescein reporter group to enhance its fluorescence.

Abstract

La présente invention concerne un nouveau procédé d'apport de molécules à l'intérieur d'une cellule dans lequel on utilise un peptide signal modifié lié à un acide nucléique peptidique. Le peptide signal comprend au moins un résidu d'acide aminé de charge positive ou un équivalent fonctionnel d'un tel résidu. Ces résidus à charge positive ajoutés servent de groupe de liaison permettant la fixation des acides nucléiques peptidiques sur le peptide signal, augmentant de la sorte le nombre de séquences nucléotidiques peptidiques délivrées par le peptide signal et renforçant, par conséquent, l'efficacité fonctionnelle de ce dernier. L'extension du peptide signal à l'extrémité C ou N-terminale via l'adjonction d'un résidu à charge simple ou multiple ou d'analogues de ce dernier permet de modifier et d'améliorer la fonction d'apport du peptide signal en augmentant les caractéristiques de solubilité et de perméabilité cellulaire de celui-ci.
