Lentiviral Vectors with Dual Fluorescence/Luminescence Reporters *Description of Technology:* Twelve lentiviral vectors that express both fluorescent and luminescent markers as a single fusion protein under various gene promoters were constructed.
Vectors have been developed previously to monitor tumors or tumor cells via bioluminescence or fluorescence alone. However, bioluminescence is not sensitive enough to sort individual tumor cells and fluorescence cannot be used effectively to view internal tumors. By combining the two reporters into a single fusion protein, the tumor can be effectively visualized within the animal as well as sorted from non-tumor cells for post-necropsy experiments. The added advantage of bioluminescent visualization allows for *in vivo* experiments that more closely simulate the biological development of tumors in organs rather than at the surface of the skin.
Additionally, since twelve different vectors with different gene promoters were developed, they can be tested in individual tumor models to find the best vector for visualizing that particular tumor cell line. The vectors are able to sustain long-term expression of both visualization markers, depending on the cell type and promoter in each vector. *Potential Commercial Applications:* • The vectors will be extremely useful for experiments in which both *in vivo* and *in vitro* analysis is desired. • The vectors can also be used for screening cancer cell lines and in tumor models for reporter gene activity. • The vectors can be useful in drug development. *Competitive Advantages:* • The bioluminescent marker allows for effective visualization of deep (non-surface) tumors in mice. • The fluorescence label permits efficient sorting of tumor cells from normal (non-labeled) cells after tumors are excised from the mice. • The vectors allow *in vivo* experiments that more closely simulate the biological development of tumors in organs rather than at surface of skin. • The vectors sustain long-term expression. *Development Stage:* • Early-stage • Pre-clinical • *In vitro* data available • *In vivo* data available (animal) *Inventors:* Dominic Esposito, Chi-Ping Day, Glenn Y.

Epigenetic Factors Associated with the Development of Age-related Macular Degeneration *Description of Technology:* Recent studies have demonstrated genetic associations between Age-related Macular Degeneration
(AMD)and specific genes. In the case of identical twins in which only one twin develops AMD, a direct genetic cause seems unlikely. NIH researchers explored the epigenetic mechanisms that control the pathogenesis of AMD. A DNA methylation study identified sites on selected gene promoters that can potentially serve as markers to distinguish patients likely to develop AMD from those less likely to develop the disease. The strongest association was found in the IL17RC gene and later studies confirmed this association, first in siblings that were discordant for AMD and then in AMD patients as compared with age-matched controls. *Potential Commercial Applications:* Diagnosis of Age-related Macular Degeneration. *Competitive Advantages:* This technology is potentially a more sensitive means of diagnosing patients with AMD. *Development Stage: In vitro* data available. *Inventors:* Lai Wei, Robert Nussenblatt, Baoying Liu, Chi-Chao Chan (NEI). *Publication:* Wei L, *et al.* Hypomethylation of the IL17RC promoter associates with age-related macular degeneration.
