UC professor looks for ways to reverse hardening of arteries

In Associate Professor LaShan Hendrix's biomedical engineering lab, students at the University of Cincinnati are studying what causes arteries to harden, leading to heart attacks and strokes.

"For so long it was treated as a given of aging," Hendrix said. "But we're learning it's not just something that happens over time with age. The cells play a role. And that's why we're trying to reverse it at the cellular level."

Hendrix and her students culture cells to recreate the calcification that takes place in the arteries.

"We can study the genes that are changing during that process; the proteins that are expressed," she said. "And we can look at what is turning those genes on and how we can go about fixing or reversing it."

Hendrix said heart disease disproportionately affects people who don't have ready access to fresh fruits and vegetables and turn to cheaper processed foods instead.

"The typical American diet today has a lot of processed food that contains a lot of phosphate, which gets deposited in your arteries," she said. "And that causes cells to produce more calcification."

For doctoral student Zack Lorton, the investigation is personal. His childhood best friend had a heart attack at 19. His grandfather suffered from kidney and heart disease.

"By working in cardiovascular research, I try to honor them and advance treatment options for those with cardiovascular complications," Lorton said.

Lorton said he came to Hendrix's lab in part because of her reputation for supporting early-career researchers. Hendrix was recognized this year with the Mentor Award from the American Association for the Advancement of Science for helping students complete their doctoral degrees in STEM.

"On a personal level, she's someone who will be in your corner. And that's someone I want around me," Lorton said.

Lucia Garcia came to UC from Spain to study in Hendrix's lab after they first worked together at Mississippi State. Garcia said heart disease is a major health concern in Europe as well.

"It's pretty similar across developed countries. Luckily, I haven't had any direct experience with my family, but you hear stories from your friends' families," she said.

UC student Jherni Fisher said she chose to study biomedical engineering because of the many research and career opportunities it provides.

"It's not just one vertical pathway. You can pursue a variety of different tracks," she said.

Fisher said she is optimistic that the questions she and Hendrix are asking will lead to improved treatments.

"I sure hope so. As with all of our research, they're stepping stones," she said.
