Murugesan et al. (2020) examined the potential molecular interactions of nine bioactive constituents of ginger selected from gas chromatography-mass spectrometry (GC-MS) analysis with novel rheumatoid arthritis (RA) target proteins (COX-2, IL-1b, MCSF, MMP-9, and TNF-alpha) for the treatment of rheumatoid arthritis. The gene discussed is MMP9; the disease is rheumatoid arthritis.
