To investigate the influence of the 8q24.21 amplification on MYC, PVT1, and circPVT1 expression, we performed quantitative RT‐PCR (qRT‐PCR) analysis in AMU‐ML2 cells and other B‐cell lymphoma cell lines, for which the chromosomal status at 8q24 is summarized in Fig. 3A. qRT‐PCR analysis showed that the expression of MYC, PVT1, and circPVT1 was significantly higher in AMU‐ML2 cells than that in PBLs from healthy donors. The gene discussed is MYC; the disease is B-cell non-Hodgkin lymphoma.
