PML and non-small cell lung carcinoma: In the next step, we sought to identify f-circRNAs based on actual BioProject RNA-Seq data at the example of H3122 cells, an NSCLC cell line harbouring the EML4-ALK fusion (BioProject ID PRJNA350335) and of various acute leukemia samples with PML-RARα fusion gene (BioProject ID PRJNA315254).
