In human ovarian cancer cell line UACC-1598, the 3q26 amplicon was previously identified on DMs and a proliferation-related function of EIF5A2 gene was reported.3 In this study, we further identified that 2p24.3 and 3q26.2 were the origins of DMs in UACC-1598, and genes including MYCN and EIF5A2, MYCNOS, RPL22L1, SLC7A14 (3′-end truncated) and two pseudogenes RPLP1P5 and RPL28P1 were co-amplified on the same ovarian DMs. Here, RPLP1P5 is linked to ovarian cancer.
