The expression of GAS5 was decreased dramatically in patients with SLE patients compared with RA patients and SS patients (both P < 0.001); linc0597 levels was significantly lower in SLE patients than in RA patients (P = 0.039), but no significant difference was observed between SLE patients and SS patients (P = 0.505); the lnc-DC levels was significantly lower in SLE patients than in SS patients (P = 0.014), but no significant difference was found between SLE patients and RA patients (P = 0.428) (Figure 3). Here, GAS5 is linked to synovial sarcoma.
