SNHG1 and ossification of the posterior longitudinal ligament of the spine: Wang et al. (2020) reported that 73 lncRNAs were upregulated and 69 lncRNAs were downregulated in ligament fibroblasts from OPLL tissues. In particular, the greatest upregulated small nucleolar RNA host gene 1 (SNHG1) expression was confirmed via RT-qPCR; even more surprising was the authors’ finding that SNHG1 acts as a sponge for miR-320b.
