Loss of KREPB9 or KREPB10 does not alter in vitro growth in either BF or PF cells. (A and B) Cumulative growth of KREPB9 null BF cells (A) or KREPB10 null BF cells (B) was indistinguishable from that of cells in which a single allele was knocked out (SKO) and also similar to that in parental 427 wt cells. (D and E) Cumulative growth of PF cells in which KREPB9 (C) or KREPB10 (D) was conditionally repressed was indistinguishable from that of cells in which KREPB9 or KREPB10 was expressed.
