After analyzing the data of PRDM5 expression in human lung samples (GEO: GSE40791), we observed decreased mRNA levels of PRDM5 in lung adenocarcinoma tissues compared with normal lung tissues (Figure 1B), which was in accord with the results from the BEAS‐2B cells and lung adenocarcinoma cell lines. Here, PRDM5 is linked to lung adenocarcinoma.
