Alpha-1-acid glycoprotein (AGP) is a key glycoprotein in the glycoprotein metabolic process, and researchers have found that AGP serves as a biomarker for BC and that AGP knockdown can inhibit the production of the inflammatory factors interleukin (IL)-1β, IL-8, and tumor necrosis factor-α in BC cells [34]. This evidence concerns the gene ATP5MK and breast cancer.
