From Table 2 and Figure 2, we can find that 15 lncRNAs are known to be associated with lung neoplasms in the lncRNADisease database, 3 lncRNAs (MINA, PVT1, and XIST) are unknown to be associated with lung neoplasms in the lncRNADisease database, which can be validated by the MNDR database (Cui et al., 2018). This evidence concerns the gene XIST and Neoplasm of the lung.
