In addition, Huang et al showed that lncRNA H19 regulated the atherosclerosis via increasing acid phosphatase 5 expression.13 Recently, the lncRNA TNK2 antisense RNA 1 (TNK2‐AS1) was found to be up‐regulated in non‐small cell lung cancer tissues and TNK2‐AS1 could promote the angiogenesis of non‐small cell lung cancer via STAT3/vascular endothelial growth factor A (VEGFA) signalling.14 However, the role of TNK2‐AS1 in the cellular functions of VSMCs has not been explored yet. The gene discussed is H19; the disease is lung cancer.
