GPI and neoplasm: In conclusion, through comprehensive analysis, we constructed a ceRNA network and identified FKBP3, GPI, LOXL2, IL22RA1, GPR37 and has-miR-148a-3p as the prognostic members of the network, and then identified Monocytes, Macrophages M1 and activated Mast cells as the prognostic tumor-infiltrating immune cells, thus constructing two nomograms that can be used as indicators for evaluating the survival of lung adenocarcinoma patients.
