In this study we displayed thirteen genes (AZGP1, CFB, NOX1, VTCN1, AGR3, GDA, TCN1, CST1, F5, CEACAM6, BPIFB1, FCGBP, and BPIFA1) to be significantly expressed in lung cancer under simulated microgravity (SMG) as compared with ground gravity in silico. This evidence concerns the gene GDA and lung cancer.
