BOONE, N.C. — Appalachian State University News By Jan Todd Posted Dec. 7, 2021 at 1:20 p.m.
A research team at Appalachian State University is investigating effective treatments for one of the most aggressive types
of breast cancer — with the goal of reducing adverse side effects.
Dr. Michael Reddish, assistant professor in App State’s A.R. Smith Department of Chemistry and Fermentation Sciences, has been awarded a grant from the North Carolina Biotechnology Center (NCBC) to study medications proposed to treat triple-negative breast cancers, which he said have “the least number of and least effective treatment options available.”
According to the National Breast Cancer Foundation Inc., a diagnosis of triple-negative breast cancer means the three receptors that fuel most breast cancer growth — estrogen, progesterone and the HER-2 gene — are not present in the tumor, and common treatments like hormone therapy are ineffective. Approximately 10% to 20% of breast cancers are triple negative.
Research from other groups has shown high concentrations of a particular sterol — 27-hydroxycholesterol (27HC) — are associated with triple-negative breast cancer and cancer metastasis, which is the development of malignant growth elsewhere in the body, Reddish said.
Medications can inhibit production of the sterol 27HC, but this presents a problem: “The inhibitors will also likely alter metabolism of vitamin D, which could lead to increased cases of osteoporosis in patients,” Reddish explained.

In his lab at App State, Reddish and his team are testing medications in hopes of finding one that inhibits the sterol production while minimizing the vitamin D reaction.
“If we can make such a finding, this would elevate that drug as a good treatment option, or other chemists could use that drug to optimize and make an even better drug,” Reddish said.
Several App State students are assisting Reddish in his work, including Ethan Harris, a senior double majoring in chemistry-biochemistry and biology-cellular/molecular biology.
“I have a passion for this kind of work because I want to help people,” Harris said. “Cancer has affected several members of my family, so I feel a connection.”
Harris, who is from Clemmons, said working in the lab has helped him realize he would like to pursue a career in research. He plans to pursue a Ph.D. in biochemistry.

About the College of Arts and Sciences
The College of Arts and Sciences (CAS) at Appalachian State University is home to 17 academic departments, two centers and one residential college. These units span the humanities and the social, mathematical and natural sciences. CAS aims to develop a distinctive identity built upon our university's strengths, traditions and unique location. The college’s values lie not only in service to the university and local community, but through inspiring, training, educating and sustaining the development of its students as global citizens. More than 6,400 student majors are enrolled in the college. As the college is also largely responsible for implementing App State’s general education curriculum, it is heavily involved in the education of all students at the university, including those pursuing majors in other colleges.
