Abstract
Black patients with laryngeal squamous cell carcinoma (LSCC), a type of head and neck cancer, have experienced higher rates of diagnosis and death compared to White patients for many years in the U.S. Scientists are still working to understand potential biological explanations for this disparity. Identifying key molecular pathways involved in this cancer could help researchers find new treatment options to specifically address the disparity. Our research focuses on small RNA molecules called microRNAs (miRNAs), which are not translated to proteins but still play a crucial role in regulating gene activity. We used computational based methods to compare miRNA levels between Black and White LSCC patients. We identified 15 miRNAs that are significantly different in Black patient tumors and found that these miRNAs may be linked to a key cellular signaling system called the mitogen-activated protein kinase (MAPK) pathway. Since the MAPK pathway plays a key role in cancer growth and progression, our findings suggest that differences in miRNA expression may alter its function in Black patients, contributing to poor LSCC outcomes.
