For nearly two decades, researcher Jesse Owens and his team at the University of Hawaiʻi<\/span><\/abbr> at M\u0101noa John A. Burns School of Medicine<\/a> (JABSOM<\/abbr>) have been pursuing a bold vision: harnessing the natural ability of DNA<\/abbr> to move itself to treat genetic disease. Supported by a $2 million grant<\/a>, their latest breakthrough, published in Nucleic Acids Research<\/a><\/em>, marks a major step forward in precision gene therapy.<\/p>\n

In nature, transposons, sometimes called “selfish DNA<\/abbr>,” can jump around the genome, a phenomenon first discovered in corn by Nobel laureate Barbara McClintock. Owens\u2019 team repurposed this mechanism to deliver healthy genes into cells, replacing faulty ones.<\/p>\n

“What we\u2019ve done in our lab is take this natural jumping mechanism and use it to deliver healthy genes into the genome, essentially replacing a faulty one with a working copy,” Owens said.<\/p>\n

Early transposon systems were limited by random insertion, but Owens\u2019 lab engineered a way to target “safe harbor” regions of DNA<\/abbr>, avoiding cancer-related genes. Their results found an average of 1.2 successful insertions per cell, a more than thousandfold improvement over previous efforts.<\/p>\n

“That means nearly every cell we worked with received the new gene. It\u2019s a huge jump,” Owens said.<\/p>\n

With National Institutes of Health (NIH<\/abbr>) funding, the team plans to apply the technology to CAR<\/abbr> T-cell immunotherapy, potentially improving cancer treatments.<\/p>\n

“This research began here in Hawaiʻi<\/span>, and it\u2019s now on the brink of something that could impact lives worldwide,” Owens reflected. “It\u2019s exciting to see how far we\u2019ve come and how much farther we can go.”<\/p>\n
