Therefore, we searched for acorrelation between H19 and p53 and prognosis in 450 patients with lung cancer from The Cancer Genome Atlas (TCGA) database, and the results showed that there was a significant difference in overall survival between TP53 (+) H19 High and TP53 (−) H19 Low groups (p = 0.017, Figure 1A). This evidence concerns the gene TP53 and lung cancer.
