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 DNAJB1; the disease is lung adenocarcinoma.
