Figure 5. Phoenixin-20 attenuated TNF-α-induced reduction of telomerase activity in RA-FLSs. RA-FLSs were stimulated with TNF-α (10 ng/mL) with or without Phoenixin-20 (10, 20 nM) for 7 days. Telomerase activity was measured (※P < 0.01 vs. vehicle group; #, ##, P < 0.05, 0.01 vs. TNF-α group, N = 5–6).
