To evaluate the possibility for clinical application, we tested the expression of DNAJB1, MCU, MPRIP, PSAP, RAI14, ZNF131 and TMC5 in 71 lung adenocarcinoma samples and paired adjacent normal tissue samples (>2 cm away from the tumor) from patients who underwent lobectomy or pneumonectomy. The gene discussed is RAI14; the disease is neoplasm.
