In the melatonin study, nine cell samples were subdivided in the following groups and investigated on day 7: 1.) control group, 2.) melatonin group (10 -9 M), and 3.) melatonin + exposure group. In the tamoxifen study, 48 cell samples were subdivided in the following groups: 1.) control group, 2.) tamoxifen group (10 -7 M), and 3.) tamoxifen + exposure group. The samples were investigated on days 4, 5, 6, and 7.
