We have previously reported that OXER1 plays a direct role in the process of cell migration and wound healing [11,12], with 5-oxo-ETE leading to an increased migratory capacity of prostate and breast cancer cells (DU-145, T47D), and testosterone–BSA and Gue 1654 inhibiting this action, an effect verified here (Supplementary Figure S4). Here, OXER1 is linked to breast cancer.
