Dr. Lyubchenko unravels DNA strand, catches it on video

In many ways, our DNA acts like a yo-yo. It unwinds and then winds up so quickly that no one has seen it -- until now.

In every cell, our genetic material is coded on a DNA strand tightly wrapped around a spool-like protein, or histone, which makes it difficult to access.

Yuri Lyubchenko, Ph.D., professor of pharmaceutical science, has found a way to unravel the long DNA strand using an electrostatic charge and has captured that action on video. His discovery may lead to the successful application of gene therapy.

So far, gene therapy, in which genes may be added or modified to prevent or treat illness, has not been successful because of an inability to deliver genes to the right cells.

"It's important to study the interactions of proteins with DNA so we understand how numerous biological processes occur," he said. "We need to know how to make the genetic code more accessible to proteins so it will be easier to replace, repair or regulate a faulty gene."
