To confirm if GGH is related to cell cycle and DNA replication in human lung cancer tissues, we performed Pearson correlation analysis between GGH mRNA expression and other genes in LUAD tissues (RNA‐seq data from three public datasets: the UM cohort,[21] the Seo cohort,[22] and TCGA‐LUAD) and found that genes positively correlated with GGH were also strongly involved in the cell cycle and DNA replication pathways (Figure 1D). The gene discussed is GGH; the disease is lung cancer.
