ATF4 promotes the growth of breast cancer in vivo. (a) ATF4-overexpressing breast cancer grew faster than MCS group in vivo. (b) Representative tumor tissues from ATF4 group and MCS group on day 16 and day 31. (c) Fluc imaging of subcutaneous breast cancers from ATF4 group and MCS group on day 0, day 4, day 7, day 10, and day 13. For each group, a representative mouse at each time point was shown. (d) Quantitative analysis of BLI signals in (c) was shown as photons/sec/cm²/sr. MCS is the abbreviation of multiple cloning sites, and MCS group is used as control here.
