The levels of miR-145-5p expression were different in the CL1-0, CL1-5, H1299, H1435 and H1563 cell lines and negatively correlated with CP expression in five lung cancer cell lines (Figure 2A and Figure 4D), with an R2 value of 0.6854 (p = 0.0419) (Figure 4D,E). This evidence concerns the gene CP and lung carcinoma.
