A novel anti-aging animal model using SIRT1 transgenic mice
Activation of SIRT1 extends lifespan by mimicking effects of caloric restriction. This technology extends the lifespan of the animals by mimicking the effects of caloric restriction. Caloric restriction has been shown to extend lifespans in many animal models by modulating sirtuins and improving energy efficiency. In this technology, the transgenic mice feature constituently-activated sirtuin 1 (SIRT1).

Background 

Aging and aging-related diseases are fast becoming a widespread concern in most developed countries, contributing to increased pressure on healthcare providers and other social services. Currently, no drugs specifically aimed at extending the human lifespan are available. This technology is an anti-aging animal model that can be implemented in the discovery of new anti-aging drugs. This gain-of-function animal model provides researchers with an effective means of studying age-related disorders and evaluating therapeutic efficacy of novel anti-aging compounds.

Activation of SIRT1 extends lifespan by mimicking effects of caloric restriction

This technology extends the lifespan of the animals by mimicking the effects of caloric restriction. Caloric restriction has been shown to extend lifespans in many animal models by modulating sirtuins and improving energy efficiency. In this technology, the transgenic mice feature constituently-activated sirtuin 1 (SIRT1). Activation of this pathway leads to downstream enhancement of multiple proteins within the caloric restriction pathway. This modulation produces beneficial effects on glucose homeostasis and insulin sensitivity, delaying the onset of conditions like diabetes, and indicates an anti-aging effect.

This gain-of-function mouse line has been developed, and its ability to reproduce effects of caloric restriction has been experimentally confirmed.

Wei Gu, Ph.D.

Applications:

  • Tool to study metabolic disease (i.e. diabetes)
  • Tool to screen for new anti-aging compounds
  • Tool to investigate the onset and pathobiology of age-related diseases (e.g. Alzheimer’s, heart disease, stroke, cancer, etc.)

Advantages:

  • Realistic replication and expression pattern of gene of interest
  • Effectively evaluates active molecules in aging-related phenotype screens
  • Mimics effects of caloric restriction through SIRT1 activation
  • Useful in vivo model for analyzing potential of small-molecule compounds for anti-aging

  • Gene therapy for inflammatory and autoimmune diseases
  • This technology comprises inhibitors of antibody production, including IgG, IgA and IgE. These peptide inhibitors are derived from naturally occurring mutations in the CRAF1 (TRAF-3) gene and they specifically inhibit CD40 mediated intracellular signaling. As the CD40-mediated signaling pathway is necessary for B-cell proliferation and antibody production, inhibitors of this pathway act as highly specific and effective immunosuppressants.

  • Parkinson's and Huntington's Treatment
  • This technology is an antisense oligonucleotide to the protein Nedd2. Nedd2 is an aspartase expressed by neuronal cells and plays a crucial role in apoptosis. When neurons are deprived of cytokines such as nerve growth factor (NGF), Nedd2 expression is upregulated as part of the apoptotic pathway. This technology is an antisense oligonucleotide (ANedd) capable of blocking expression of Nedd2, thereby inhibiting apoptosis.
