  • Publication number: 20080233574
    Abstract: The invention pertains to a method for identifying one or more regions within a genome of an organism of interest that mediate the expression of one or more genes of interest. The method comprises identifying a first and a second organism of interest, the first organism of interest is characterized by exhibiting a measurable response to an environmental stimulus, or otherwise, exhibiting a phenotype associated with differential gene expression associated with a process of interest. The second organism of interest is characterized by lacking or not exhibit as strong a response to the stimulus as that observed within the first organism of interest, or it exhibits a different phenotype compared with that of the first organism of interest, wherein the different phenotype is associated with the process of interest, or it exhibits a phenotype of interest that segregates when compared with the first organism of interest, or a combination thereof.
    Type: Application

  • Patent number: 6492134
    Abstract: The present biotechnological approach for the production of polyhydroxyalkanotes (PHAs) uses microbial systems. The high production costs makes them substantially more expensive than synthetic plastics. Engineering a novel pathway in eucaryotic cell systems is a beneficial alternative to the production of PHAs in bacteria. This pathway will initially produce free (C8) fatty acids from the fatty acid synthetic pathway through the action of thioesterase, that will then add a CoA moiety to the free fatty acid through the action of an acyl-CoA synthetase, that will produce 3-ketoacyl-CoAs from the acyl-CoA through the action of a thiolase, that will produce R-(−)-OH-acyl-CoAs from the 3-keto acid CoAs through the action of a dehydrogenase isoform from yeasts. These R-(−)-3-OH-acyl-CoAs will finally be used as substrate for the PHA synthase reaction.

  • Patent number: 5990385
    Abstract: This invention is directed to characterizing a host system suitable for the production of functional transgenic proteins, such as anti-human IgG, for use in applications requiring Government regulatory approval. It is well known that regulatory agencies required stable, consistent master cell banks and master cell lines for the production of transgenic proteins in order to ensure sufficient material for appropriate characterization, clinical trials, and potential sales. Current plant production systems require the establishment of seed banks for this purpose. However, there are many draw backs related to such a system for the production of a continuous reliable transgenic protein source. An aspect of this invention is directed to characterizing a plant production system suitable for transgenic proteins that meet the stringent regulatory requirements.
