OSER1-AS1 was lowly expressed in RA samples. (a-b) OSER1-AS1 was lower in serum samples and synovial tissues of RA patients(n = 30) and the compared healthy controls(n = 30). (c) ROC analysis indicated that the expression level of OSER1-AS1 in serum samples could be a diagnostic biomarker for RA. (d) Expression levels of OSER1-AS1 in TNF-α-induced RA-FLSs. All experiments were conducted in triplicate. *p < 0.05, **p < 0.01, ***p < 0.001.
