Drosophila homologues of genes and proteins implicated in cancer and methods of use
Granted: June 17, 2003
Patent Number:
6579701
Novel nucleic acids that are homologs of genes implicated in cancer are described that have been isolated from Drosophila melanogaster. These novel nucleic acids can be used to genetically modify metazoan invertebrate organisms, such as insects and worms, or cultured cells, resulting in novel gene expression or mis-expression. The genetically modified organisms or cells can be used in screening assays to identify candidate compounds which are potential pesticidal agents or therapeutics…

The present invention relates to isolated Raspberry Bushy Dwarf Virus (RBDV) nucleic acid sequences which encode RBDV coat and movement proteins or polypeptides and mutant or modified forms thereof. The invention further relates to heterologous nucleic acid constructs, vectors, transformation methods, plant cells and plants comprising such RBDV-encoding nucleic acids and methods for inducing resistance to RBDV by transforming plants with a nucleic acid construct comprising RBDV protein…
Methods for identifying anti-cancer drug targets
Granted: March 11, 2003
Patent Number:
6531644
Methods, transformation constructs, and transgenic animals for identifying anti-tumor agents and anti-tumor drug targets are described. The transformation constructs are used to generate transgenic animals that have altered expression of an oncogene or tumor suppressor gene in a target tissue that is dispensable for viability and reproduction. In some embodiments, the altered expression results in abnormal proliferation of the target tissue and normal proliferation in all other tissues.…
Universal markers of transgenesis
Granted: February 11, 2003
Patent Number:
6518481
The invention relates to methods, cells and nucleic acids for making transgenic animals. The methods generally comprise introducing into a genome of an animal a genetic construct comprising a transcriptional regulatory element operably linked to a heterologous marker gene encoding a marker, wherein the element drives expression of the marker across genera transgenic in the construct sufficient to visually detect the marker in photoreceptive cells or organs, and selecting for transgenesis…

Granted: January 28, 2003
Patent Number:
6511824
Tandem pore domain weak inward rectifying K+ (TWIK) channel nucleic acids and proteins that have been isolated from Drosophila melanogaster and Leptinotarsa are described. The TWIK channel nucleic acids and proteins can be used to genetically modify metazoan invertebrate organisms, such as insects, coelomates, and pseudocoelomates, or cultured cells, resulting in TWIK channel expression or mis-expression. The genetically modified organisms or cells can be used in screening assays to…
Methods for identifying anti-cancer drug targets
Granted: December 3, 2002
Patent Number:
6489127
Methods, transformation constructs, and transgenic animals for identifying anti-tumor agents and anti-tumor drug targets are described. The transformation constructs are used to generate transgenic animals that have altered expression of an oncogene or tumor suppressor gene in a target tissue that is dispensable for viability and reproduction. In some embodiments, the altered expression results in abnormal proliferation of the target tissue and normal proliferation in all other tissues.…
