  • Compositions and methods for recombinant synthesis of high molecular weight hyaluronic acid
    Patent number: 9315588
    Abstract: Provided is a novel hyaluronan synthase (HAS2), isolated nucleic acids encoding it, and expression vectors which express the novel HAS2. Also provided are cell cultures which contain cells which harbor the expression vectors, methods of using the cell cultures to produce high molecular weight hyaluronic acid, and cell culture media that contains the high molecular weight hyaluronic acid.
    Type: Grant
    Filed: February 4, 2013
    Date of Patent: April 19, 2016
    Assignee: University of Rochester
    Inventors: Vera Gorbunova, Andrei Seluanov

  • Compositions Comprising High Molecular Weight Hyaluronic Acid and Methods For Producing Same
    Publication number: 20130131009
    Abstract: This invention provides cell culture compositions which produce significant quantities of high molecular weight hyaluronic acid. The cell cultures are obtained from cells of mole rats, such as naked mole rats and blind mole rats. The high molecular weight hyaluronic acid can be collected in the conditioned media of these cell cultures. These cell cultures provide a convenient source of large quantities of high molecular weight hyaluronic acid.

  • Rad51 derived cancer cell specific promoters for targeted anti-cancer therapy
    Patent number: 8188252
    Abstract: Provided are compositions and methods for inhibiting growth of cancer cells. The method of the invention relates to delivering to cells an effective amount of a composition that contains a polynucleotide having a Rad51 promoter or a polynucleotide having at least 95% similarity to a Rad51 promoter. The Rad51 promoter is operably linked to a coding region for a cytotoxic agent. In vitro and in vivo results demonstrating effectiveness of the polynucleotides of the invention are presented.
