Identification of the alternative polyadenylation (APA)-indicator genes in non-small cell lung cancer. (a) The APA status of the 16 genes selected in silico was confirmed in seven clinical lung cancer specimens and eight normal lung tissue specimens, and the top 10 genes were selected as the APA-indicator genes. The APA status was evaluated on the basis of the logarithm of the proportion of the full-length transcripts of the lung cancer specimens normalized to that of the normal lung tissue specimens. Results are shown as the average ± SD. The columns over the red line indicate that the proportion of the full-length transcripts of the lung cancer specimens is less than half of that of the normal lung tissue specimens. (b) The genes selected based on the results of past studies were associated with a lower frequency of 3′UTR shortening as compared to the APA-indicator genes.
