In agreement with previous findings in epithelial, glioma, and pancreatic cells [37,38,39], PSMB8-AS1 was found to be enriched in monocyte cytoplasm (Figure 4F, third panel), suggesting that this lncRNA may regulate expression of its target(s) at the post-transcriptional level [29]. Here, PSMB8 is linked to central nervous system cancer.
