OR52E8 is an olfactory receptor localized to the plasma membrane with odorant receptor activity. Based on limited published evidence, OR52E8 was identified as an upregulated gene in a competing endogenous RNA network associated with invasive growth hormone-secreting pituitary adenomas 1. The functional significance of OR52E8 expression in pituitary pathology remains unclear, as the study primarily characterized transcriptional changes without demonstrating direct functional roles for this olfactory receptor in adenoma invasiveness.
