  • Publication number: 20130164270
    Abstract: The present invention relates to engineered polynucleotides and constructs comprising nucleic acid sequences encoding a specific splice-variant (sFLT1-14) of the VEGFR family Flt-1, methods for efficient propagation and expression thereof and compositions and uses thereof. More particularly, the invention relates to isolated polynucleotides comprising a nucleic acid sequence coding for sFlt1-14 or any fragment thereof comprising the serine-rich C-terminus region of said sFlt1-14, wherein at least one of the TCA serine coding codons in said serine-rich C-terminus region of sFlt1-14 as encoded by the nucleic acid sequence of SEQ ID NO. 1, is replaced by any one of TCT, TCC, TCG, AGT, AGC. The invention further provides compositions and method of treating VEGF-associated medical conditions using the polynucleotides of the invention.

  • Publication number: 20060084622
    Abstract: The present invention relates to a novel VEGF protein product, and nucleic acid encoding the novel protein product, comprising exons 1-6 and 8 of the VEGF gene, and its use thereof in treating the cardiovascular system and its diseases through effects on anatomy, conduit function, and permeability. VEGF145 has been found to be an active mitogen for vascular endothelial cells and to function as an angiogenic factor in-vivo. VEGF145 has novel properties compared with previously characterized VEGF species with respect to cellular distribution, susceptibility to oxidative damage, and extra-cellular matrix (ECM) binding ability. The present invention provides methods of treating the cardiovascular system, enhancing endothelialization of diseased vessels, and enhancing drug permeation by providing the novel VEGF protein product. The invention also provides expression vectors, compositions, and kits for use in the methods of the invention.

  • Patent number: 6653132
    Abstract: An isolated and cloned translation control element, and analogues thereof, having the nucleotide sequence as set forth in SEQ ID NO:7 and designated SP163, are disclosed. The translation control element controls cap-independent mRNA translation via an internal ribosome entry site (IRES). The present invention provides expression vectors comprising the translation control element SP163 or its analogues operatively linked to a gene sequence to be expressed. In alternative embodiments, the expression vector comprises at least two nucleic acid sequences to be translated and SP163 is operatively linked to at least one of the sequences to be translated. The sequences to be translated may be linked to only one promoter in an embodiment. The present invention further provides a method for facilitating and enhancing cap-independent translation of mRNA by including in an expression cassette a translation control element having the nucleotide sequence as set forth in SEQ ID NO:7 and designated SP163.

  • Patent number: 6583276
    Abstract: The present invention relates to novel VEGF protein products, and nucleic acids encoding these novel protein products, comprising exons 1-6 and 8 of the VEGF gene, and derivatives thereof, and these uses in treating the cardiovascular system and its diseases through effects on anatomy, conduit function, and permeability. VEGF145 and its derivatives have been found to be active mitogens for vascular endothelial cells and to function as angiogenic factors in-vivo. VEGF145 and its derivatives have novel properties compared with previously characterized VEGF species with respect to cellular distribution, susceptibility to oxidative damage, and extra-cellular matrix (ECM) binding ability. The present invention also relates to derivatives of VEGF145 which have altered properties in that they have altered biological activity and altered heparin-binding activity when compared to VEGF145.
