In fact, the high expression of glycogen synthase-1 in RA-FLSs can lead to the excessive accumulation of glycogen and inhibit AMPK expression, leading to the high expression of matrix metallopeptidase (MMP)-1, MMP-9, IL-6, and CCL-2, along with increased proliferation and migration of FLSs. The gene discussed is MMP1; the disease is rheumatoid arthritis.
