PSMB8 and systemic sclerosis: Four out of ninety-nine lncRNAs, namely NRIR, PSMB8-AS1, RP5-1091N2.9, and RP11-24F11.2, were expressed at significantly higher levels in at least two groups of SSc patients as compared to their respective healthy donors in the “definite SSc” cohort (Figure 3A), whereas only NRIR was significantly up-regulated in ncSSc and showed a trend in eaSSc (FC = 1.30, p = 0.104) in the “non-fibrotic” cohort (Figure 3B).
