Consistent with the result of qRT-PCR assay, we find that lnc-GAN1 is mainly located in the cytoplasm rather than in the nucleus in the two lung cancer cells (Fig. 5a right, and Additional file 2: Fig. S3) and NSCLC tissues (Additional file 2: Fig. S3), suggesting that lnc-GAN1 may act as a regulator at the post-transcriptional level in cytoplasm. Here, GAN is linked to non-small cell lung carcinoma.
