HLA-G and synovial sarcoma: Shi et al. analyzed expression profiles of lncRNAs in the LSGs of patients with SS and healthy controls by real-time polymerase chain reaction, and revealed that eight lncRNAs (ENST00000420219.1, ENST00000455309.1, n336161, NR_002712, ENST00000546086.1, lnc-UTS2D-1:1, n340599, and TCONS_l2_00014794) were significantly upregulated in SS, each of which was correlated with disease duration or biomarkers such as ESR, rheumatoid factor, and serum β2 microglobulin levels [63].
