UTHSC’s Dr. Meiyun Fan Receives $100,000 to Study Recurrent Form of Breast Cancer

Meiyun Fan, MD, PhD, associate professor at UTHSC, has received a $100,000 grant to study Basal-Like Breast Cancer.

Meiyun Fan, MD, PhD, an associate professor of Pathology at The University of Tennessee Health Science Center (UTHSC), has received a $100,000 grant from the National Cancer Institute to study an aggressive form of breast cancer known as Basal-Like Breast Cancer, or BLBC. The grant will be distributed over two years.

Approximately 40 percent of patients with BLBC experience metastatic relapse within three years, Dr. Fan said. It usually spreads, she said, to the brain, the lungs or the liver – all very serious forms of cancer. “Nationally, only about 15 percent of breast cancer is BLBC, but about 40 percent of breast cancer in premenopausal African-American women is BLBC,” Dr. Fan said.

What Dr. Fan described as “a small RNA” — a nucleic acid found in living cells, similar to DNA — named miR-18a-5p plays a role in the signaling pathway that allows some tumor cells to “turn off” and become dormant during chemotherapy. “They stop proliferating, but they won’t respond to the chemotherapy. They basically hide from the chemotherapy and escape.”

Dr. Fan plans to study the exact role miR-18a-5p plays in making BLBC cells resistant to treatment. Her results will contribute to a broader understanding of drug resistance in cancer cells.
