Fig. 1From: Identification and bioinformatics analysis of lncRNAs in serum of patients with ankylosing spondylitisRNA-seq data of differential lncRNA expression profiles in serum from AS patients and NC. A PCA plot of lncRNA expression profiles. B Volcano plot showing differentially expressed lncRNAs. C Heatmap of differentially expressed genes between the AS and NC groups. AS = ankylosing spondylitis, lncRNA = long non-coding RNA, PCA = principal component analysisBack to article page
