To probe the regulatory role of berberine in impacting the autophagy-apoptosis equilibrium within rheumatoid arthritis (RA) patient-derived fibroblast-like synoviocytes (FLSs), and exploring the associated mechanisms.
An assessment of berberine's (10, 20, 30, 40, 50, 60, 70, and 80 mol/L) inhibitory impact on RA-FLS proliferation was undertaken employing the CCK-8 methodology.
