Based on the analysis with the Oncomine database (Figure 10), ESPL1 expression was identified to be significantly overexpressed in the five lung cancer datasets, including squamous cell lung carcinoma [7,8] (FC = 2.741 and 2.447, respectively), large cell carcinoma [8] (FC = 4.807) and lung adenocarcinoma [11,12] (FC = 2.249 and 2.339, respectively). This evidence concerns the gene ESPL1 and squamous cell lung carcinoma.
