At the same time, analysis of previously published PAR-CLIP data from seven different EBV positive cell lines including lymphomas and the nasopharyngeal carcinoma cell line, C666 [37–40] did not reveal evidence of microRNA association with LMP2 exons 2–8 suggesting that circLMP2_E8_E2 may not play a microRNA sponge function. This evidence concerns the gene PSMB9 and lymphoma.
