We further used DAVID (Huang Da et al., 2009b; Huang Da et al., 2009a) to search for those genes from the predicted target genes that are related to tumor, and found the target genes of LYN, RASAL2, FZD4, and GNG2 for further study (Choi et al., 2010; Yajima et al., 2012; Ma et al., 2017; Pan et al., 2018). The gene discussed is RASAL2; the disease is neoplasm.
