TFRC and keloid: Recently, Yang et al. (2024) measured iron content and the expression of ferroptosis-related genes including Solute Carrier Family 7 Member 11 (SLC7A11, also known as xCT), GPX4, transferrin receptor (TFRC), and nuclear factor erythroid 2-related factor 2 (Nrf2) in keloid tissues, comparing the data to normal skin tissue.
