According to the public database http://ualcan.path.uab.edu/index.html, the expression of WDHD1 (Figure 2B) and ARPC1A (Supplementary Figure 1B) in lung cancer tissues was higher than that in the adjacent tissues, suggesting that the upregulation of WDHD1 and ARPC1A may be one of the reasons for the occurrence and development of LUAD. This evidence concerns the gene WDHD1 and lung cancer.
