  • Patent number: 6693226
    Abstract: The invention provides transgenic, non-human animals and transgenic non-human mammalian cells harboring a transgene encoding a p25 (activator of the protein kinase cdk 5) polypeptide. The two neuropathological lesions associated with Alzheimer's disease (AD) are amyloid plaques and neurofibrillary tangles (NFTs), composed predominantly of amyloid &bgr; peptides and hyperphosphorylated tau, respectvely. While animal models for plaque formation exist, there is no animal model that recapitulates the formation of NFTs. This invention provides transgenic mice that overexpress human p25, an activator of cdk5, resulting in tau that is hyperphosphorylated at AD-relevant epitopes. Deposition of tau is detected in the amygdala, thalamus and cortex. Increased phosphorylated neurofilament, silver-positive neurons and neuronal death are also observed in these regions. We conclude that the overexpression of p25, an activator of cdk5, is sufficient to produce hyperphosphorylation of tau and neuronal death.

  • Patent number: 6689611
    Abstract: The present invention is directed to compositions and methods for producing avermectins, and is primarily in the field of animal health. The present invention relates to the identification and characterization of two novel genes, herein referred to as the aveR1 and aveR2 genes, that are involved in regulating avermectin polyketide synthase (PKS) expression and avermectin biosynthesis in Streptomyces avermitilis. The present invention is based on the discovery that inactivation of these genes results in an increase in the amount of avermectin produced by S. avermitilis.
