PLOD3 and adenocarcinoma: To further determine the association between PLOD3 and lung cancer in clinical-pathological features, we analyzed PLOD3 expression in 156 primary lung cancer tumors relative to that in the corresponding tumors from the same patients (large cell lung carcinoma [n = 19], adenocarcinoma [n = 45], and squamous cell carcinoma [n = 27]) (Fig. 1c).
