Gene Editing Nanomedicines to Correct Pathogenic Mutations in Retinal Pigmented Epithelium

Bioengineering advances have now made it feasible for precision gene editing directly in patient tissues with the goal of not only treatment, but of a cure. In this project, the priority is genetic disorders that inflict the eye, specifically the retinal pigmented epithelium (RPE) that surrounds the retina.

Existing state-of-the-art approaches to edit cells within human tissues have significant limitations both with respect to safety and efficacy. The nanomedicine approach of this project is anticipated to overcome these limitations and will set the foundation for a new paradigm in developing genomic medicine.

This project will use advances in biomaterials to generate nonviral, synthetic nanocarriers of CRISPR-Cas9 gene editing machinery for targeted delivery to the RPE. Such research would generally expand the types of tissues that could be edited and hence the spectrum of disease where genomic medicine could have an impact. This hypothesis will be tested to precisely edit pathogenic point mutations in vivo within transgenic mouse disease models and in patient-derived, induced pluripotent stem cell (iPSC)-based disease models.

WARF Discovery Initiative announces new round of UW2020 research awards

May 3, 2018 By Natasha Kassulke

Seventeen innovative projects on such diverse topics as personalizing diabetes prevention and treatment, transforming wood into a renewable electronic material, improving outcomes for incarcerated parents and their children, and advancing the frontier of fusion energy sciences have been chosen to join the UW2020: WARF Discovery Initiative grant cohort.

These projects, with an average award amount of $432,442, were among 111 proposals submitted from across the UW–Madison campus. The initiative is funded by the Office of the Vice Chancellor for Research and Graduate Education and the Wisconsin Alumni Research Foundation.

This is the fourth round of UW2020 project selections and brings the total number of UW2020 projects to 66 since the first round awards were announced in 2016. This round includes six infrastructure projects and 11 research projects that cross multiple divisions on campus. Funded projects include 125 faculty and academic staff investigators on the project teams from 10 schools and colleges.

The projects were reviewed by faculty across the university, ultimately involving 102 reviewers. The UW2020 Council, a group of 17 faculty from all divisions of the university, evaluated the merits of each project based on the reviews and their potential for making significant contributions to their field of study.

 

The goal of UW2020 is to stimulate and support cutting-edge, highly innovative and groundbreaking research at UW–Madison and to support the acquisition of shared instruments or equipment that will foster significant advances in research.

“While previous rounds of UW2020 projects are now maturing and realizing their potential, we are excited to infuse the initiative with a new class of inspiring and novel projects that continue to showcase UW–Madison’s highly competitive and forward-thinking world-class faculty and staff researchers,” says Norman Drinkwater, interim vice chancellor for research and graduate education.

“UW–Madison remains very grateful to WARF for continuing to support and partner with us on this initiative,” he says.

 

The Graduate School also supplies direct support for some research assistants.
