To analyze the relationship between the CRTAC1 expression and chemosensitivity in NSCLC, we used the gene chip probe ID 221204_s_at that represented by CRTAC1 to screen public microarray datasets for predicting the response of NSCLC patients receiving cisplatin-based chemotherapy from the Gene Expression Omnibus (GSE29013 and GSE14814). Here, CRTAC1 is linked to non-small cell lung carcinoma.
