The expression of PDK1 in human bronchial epithelial cell line BEAS-2B and NSCLC cell lines was detected by qRT-PCR, uncovering that PDK1 was notably highly expressed in NSCLC cells (Figure 3E), which was the opposite of the expression of miR-30d-5p in NSCLC. Here, PDK1 is linked to non-small cell lung carcinoma.
