Zscan4, a Therapeutic Target for Cancer, Regenerative Medicine and Aging

Description of Invention: This technology has broad potential for the development of therapeutics for cancer, diseases of aging, and regenerative medicine, and targets Zscan4, a gene that regulates telomere length and genomic stability in embryonic stem (ES) cells.

The ability to maintain genomic stability in ES cells and other stem cells is critical for the development of stem cell-based therapies; genomic stability and telomere length are also active areas of cancer and aging research. NIA investigators have discovered that the Zscan4 gene regulates telomere length and genomic stability in ES cells, and plays an essential role in early embryonic development; this activity is independent of telomerase activity. The investigators have shown that ablation of Zscan4 results in shortened telomere length and deterioration of the karyotype of ES cells, and that Zscan4 overexpression increases telomere length.

This technology discloses methods for increasing genome stability or increasing telomere length in an ES cell, and methods of treating a subject in need of ES cell therapy. Also disclosed are methods of promoting blastocyst outgrowth of embryonic stem cells, as well as Zscan4 expression vectors and methods of identifying stem cells expressing Zscan4.

Applications

  • Development of therapeutics for cancer treatment, aging, and regenerative medicine.
  • Development of assisted reproduction technologies.
  • Studies of early embryonic development.

Development Status: In vitro and in vivo studies have been performed.

mFPR2 Transgenic and Knockout Mouse Models for Alzheimer's and Other Inflammatory Diseases

Description of Invention: Human Formyl Peptide-Like Receptor 1 (hFPLR1) has been implicated in host defense for disease processes including Alzheimer's disease, infection, and other inflammatory diseases. hFPLR1 and its mouse homologue Formyl Peptide Receptor 2 (mFPR2) are G-protein coupled receptors that are expressed at high levels on phagocytic leukocytes, mediating leukocyte chemotaxis and activation in response to a number of pathogen- and host-derived peptides. Activation of hFPRL1/mFPR2 by lipoxin A4 may play a role in preventing and resolving inflammation. Also, hFPRL1/mFPR2 has been shown to mediate the chemotactic activity of amyloid beta 1-42, a key pathogenic peptide in Alzheimer's disease.

Available for licensing are mice expressing the mFPR2 transgene on either the FVB or C58BL background, as well as mFPR2 knockout mice on the C57BL background. These mice are anticipated to be highly useful in the study of a wide variety of inflammatory, infectious, immunologic and neurodegenerative diseases.

Applications

  • Drug development model for Alzheimer's disease and other inflammatory diseases.
  • Tool to probe the role of hFPRL1/mFPR2 in host responses in a variety of disease processes, including inflammatory, infectious, immunologic, and neurodegenerative disease.
