As mentioned previously we have verified the protein expression level of USP32 by Western blot in seven selected NSCLC cell lines, we selected H460 and H1299 cells for overexpression experiment using Myc-tagged USP32 plasmid, and A549 and H1299 cells for knockdown experiment using two small interfering RNAs, siUSP32 #1, siUSP32 #2. Here, USP32 is linked to non-small cell lung carcinoma.
