Publication number: 20030003453Abstract: This invention is directed to a DNA sequence comprising a nucleotide sequence encoding a variant paraoxonase protein and to said variant paraoxonase protein as well as a method and a kit for detecting a risk of cancer, coronary or cerebrovascular disease, hypertension, type 2 diabetes , dementia, joint arthrosis, cataract, or sensitivity to organophosphorus compounds in a subject, the method comprising isolating genomic DNA from said subject, determining the allelic pattern for the codon 102 of the paraoxonase encoding PON1 gene in the genomic DNA, identification of Ile101Val mutation indicating said risk being increased and for targeting paraoxonase activity modulating therapies. Further this invention relates to transgenic animals comprising a human DNA molecule encoding said variant paraoxonase and to a method of phenotype-targeted gene sequencing.Type: ApplicationFiled: March 20, 2001Publication date: January 2, 2003Inventors: Jukka T. Salonen, Marja Marchesani, Tomi-Pekka Tuomainen, Jari Kaikkonen

Publication number: 20020192784Abstract: The present invention makes use of a chimeric gene that, when incorporated into an appropriate host, results in the overproduction of S-adenosylmethionine without the need to supply the host with a source of untransformed methionine. The need for the methionine source is eliminated because the appropriately chosen host manufactures the amino acid on its own, and when the host is modified by the inclusion of a chimeric gene of the present invention, it transforms the methionine that is produced into S-adenosylmethionine. In addition, the same chimeric gene causes accumulation of methionine and increase in folate content in the same host. One form of the present invention is a fused gene encoding for methylene tetrahydrofolate reductase (MTHFR) made up of an N-terminal domain from a yeast organism and a C-terminal domain from a plant species. An example of a suitable plant species is Arabidopsis thaliana. An example of a suitable yeast organism is Saccharomyces cerevisiae.Type: ApplicationFiled: March 29, 2002Publication date: December 19, 2002Inventors: Dean R. Appling, Andrew D.
