To further examine the effect of RSU1P2 on tumor growth in vitro, we obtained HeLa pooled clones (HeLa/ RSU1P2-full) that stably expressed higher levels (Supplementary Figure S1D) of RSU1P2 and HeLa/pcDNA3 pooled clones by G418 screening and injected the cells into the flanks of 7 nude mice. Here, RSU1P2 is linked to neoplasm.
