SLC16A1 and non-small cell lung carcinoma: A putative circ-SLC16A1 back-spliced junction fragment was confirmed by RT-qPCR amplification with the primers used to amplify the complementary DNA, but not from genomic DNA, as verified by Sanger sequencing (Fig. 1G), suggesting that abnormal expression of circ-SLC16A1 is associated with progression of NSCLC.
