Here we analyze the gene expression profiles of aforementioned RNA-sequencing examination to identify an oncogene, Homeobox A11 (HOXA11), which was a transcription factor and has been reported to play contradictory roles in lung adenocarcinoma 3, lung squamous cancer 4, renal cell carcinoma 5, urothelial bladder cancer 6 and glioblastoma 7. This evidence concerns the gene HOXA11 and lung adenocarcinoma.
