Effects of RIZ1 expression on colorectal cancer cell lines HCT116 and DLD1

Cell line	Cells, difference in %
	Apoptosis	G1	S	G2/M
HCT116	+25  ± 2.0	−47  ± 1.3	+6.1  ± 0.7	+20  ± 0.8
DLD1	+9.5  ± 1.2	−28  ± 2.1	−2.2  ± 0.5	+26  ± 1.7

DNA histogram analysis was performed 72 h after adenovirus (Ad) RIZ1 or AdNull virus infection. The values shown represent the difference in percentage of cell populations between AdRIZ1- and AdNull-infected cells. The increase caused by AdRIZ1 over AdNull is indicated by a plus sign (+), and a decrease is indicated by a minus sign (−). The values represent the mean ± SD of three experiments.
