  • Patent number: 6261760
    Abstract: This invention provides a novel intracellular recycling free cholesterol pathway whose activity is required for cell division. The pathway provides the cholesterol needed for cell division prior to separation of daughter cells (mitosis). The new pathway offers several targets from pharmaceutical intervention, either via small molecules (such as sterol analogs) or by molecular engineering (preventing the cell from accumulating cholesterol by promoting free cholesterol efflux by transfection of caveolin cDNA).

  • Patent number: 6192475
    Abstract: A system and method for rewriting software into a protected form, called cloaked software, such that this cloaked form is protected from analysis or reverse engineering while at the same time the cloaked software is executable. Further, said cloaked software may be set up so that it requires a correct key or keys to be supplied, when it is to be run, for it to execute correctly. Cloaking modifies the basic operations within the software so that the logical connections or data flow among the program operations is no longer visible. In fact, cloaking makes the correct dataflow among operations dependent on a complex interrelated set of addressing operations within the cloaked program. These addressing operations are designed so that their analysis is equivalent to a computationally intractable NP-complete problem. This situation prevents reverse-engineering and unauthorized tampering.

  • Patent number: 6087341
    Abstract: Skin cells are genetically altered to express a gene product encoded by an introduced polynucleotide. Specifically, the invention involves introduction of a nucleotide of interest into a skin cell by topical application of a polynucleotide that is substantially free of liposomes or charged lipids, where the skin can be either treated or untreated prior to application. Similarly, the invention involves introduction of a nucleotide of interest into a skin cell by topical application of a polynucleotide formulation comprising a liposome or charged lipid, wherein the skin is not treated by removal of hair prior to application. The method of the invention serves as a platform for delivering polynucleotides to skin cells for expression therein for any of a variety uses including, but not limited to genetic immunization.
