Abstract: The present invention discloses cell permeable Nm23 recombinant proteins where a macromolecule transduction domain (MTD) is fused to a metastasis suppressor Nm23. Also disclosed are polynucleotides encoding the cell permeable Nm23 recombinant proteins, an expression vector containing the cell permeable Nm23 recombinant protein, and a pharmaceutical composition for preventing metastasis which contains the cell permeable Nm23 recombinant protein as an effective ingredient. The cell permeable Nm23 recombinant proteins of the present invention can induce KSR phosphorylation and inactivation and inhibit Ras-mediated MAPK cascade by efficiently introducing a metastasis suppressor Nm23 into a cell. Therefore, the cell permeable Nm23 recombinant proteins of the present invention can be effectively used as an anti-metastatic agent capable of preventing cancer metastasis by inhibiting the proliferation, differentiation and migration of cancer cells.

Abstract: The present invention discloses cell permeable p18 recombinant proteins where a macromolecule transduction domain (MTD) is fused to a tumor suppressor p18. Also disclosed are polynucleotides encoding the cell permeable p18 recombinant proteins, an expression vector containing the cell permeable p18 recombinant protein, and a pharmaceutical composition for treating p18 deficiency or failure which contains the cell permeable p18 recombinant protein as an effective ingredient. The cell permeable p18 recombinant proteins of the present invention are capable of efficiently introducing a haploinsufficient tumor suppressor p18 into a cell, and thus, can activate cell signaling mechanisms involved in the activation of ATM and p53 that induce cell cycle arrest and apoptosis in response to DNA damage or oncogenic signals. Therefore, the cell permeable p18 recombinant proteins of the present invention can be effectively used as an anticancer agent.

Abstract: Glycoproteins containing high mannose oligosaccharides are obtained and used to generate antibody to the mannose portion of the molecule. Such antibodies can be used in a diagnostic assay. The glycoproteins can be used to generate neutralizing antibody.

Abstract: The present invention discloses cell permeable Nanog and Oct4 recombinant proteins that comprise a kaposi fibroblast growth factor 4 (kFGF4)-derived macromolecule transduction domain (MTD). Also disclosed are polynucleotides encoding the cell permeable Nanog and Oct4 recombinant proteins, a method of increasing self-renewal and suppressing differentiation of stem cells by treating the cells in combination with the cell permeable Nanog and Oct4 recombinant proteins, and the combined use of the cell permeable Nanog and Oct4 recombinant proteins for increasing self-renewal and suppressing differentiation of stem cells.

Abstract: Gene delivery of a detoxifying agent is described.

Abstract: This application provides a method to produce recombinant bioscavenger molecules to be used as human treatments to protect against toxicity resulting from exposure to chemical/biological agent toxins or drugs. This invention relates to the production of glycoproteins that exhibit poor stability in vivo and are thus inadequate as therapeutic treatments without the additional post-translational modifications of the expressed molecules. In one embodiment, the method combines molecular and biochemical technologies; first for the expression of recombinant molecules and second for the in vitro glycoslyation of the purified or partially purified expressed molecules, intended to mimic the glycoprotein profiles of the native molecules. In another embodiment, post-translation modifications can be provided by direct genetic modification of the cells used in the protein expression system. Although the invention is intended for in vivo use, the invention allows for decontamination in vitro.

Abstract: The present invention relates to a treatment by pulmonary delivery of bioscavengers to animals as an effective antidote to prevent toxicity produced by exposure of an animal to nerve agents and other toxic substances.
