LGALS9 and non-small cell lung carcinoma: Among the top 10 regulated genes from the cisplatin-refractory NSCLC clones were dickkopf-1 (DKK1) and X-ray repair cross-complementing protein 2 (XRCC2) from the first replicate, and lectin, galactoside-binding, soluble 9 (LGALS9) from the third replicate (Fig. 2, labeled with *).
