Some lncRNAs are located in cytoplasm, for example lncRNA Ptenp1 is located in the cytoplasm and regulate the tumour suppressor, Pten8, 9; LncRNA Tincr is also located in cytoplasm and interacts with mRNA to increase their stability10; In addition, other lncRNAs such as Ror,11 HULC,12 linc‐MD1,13 1/2‐sbs RNAs,14 and Gadd715 are also located in the cytoplasm and play important functions in biological processes. The gene discussed is PTENP1; the disease is neoplasm.
