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. The gene discussed is GDA; the disease is lung carcinoma.
