LncRNAs involved in many cancer‐related research mechanisms.2 For example it is proved that SNHG1 is up‐regulated in lung cancer cells lines and in vitro experiments and down‐regulation of SNHG1 suppresses lung cancer cell proliferation.10 A plenty of lncRNAs attracted the attention of many scientists, proved that several lncRNAs involved in the regulatory mechanism of PCa, including lncRNA PCGEM1, lncRNA SOCS2‐AS1, lncRNA CTBP1‐AS, lncRNA DRAIC and lncRNA PCAT29.2 Xu et al5 found that PCAT‐1 promoted proliferation, migration, invasion and repressed apoptosis of PCa cells. This evidence concerns the gene SNHG1 and lung carcinoma.
