Meanwhile, we validated the enhanced expression of HDAC1 in NSCLC cell lines, including A549, H1299, H460, MES-1, H226, and H661, by comparing with that of normal human bronchial epithelial cell lines BEAS-2B and 16HBE (Figure 1(c)). This evidence concerns the gene HDAC1 and non-small cell lung carcinoma.
