To obtain evidence regarding the effects of serum factors on the expression of the CanCord34 genes, we examined the effects of serum starvation for 72 h on the levels of EEF1D, TIGD5, C8ORF73/MROH6, and BOP1 in the breast cancer SKBR-3, cervical cancer SiHa, and neuroblastoma IMR-32 cell lines (Supplementary Figure S7C). Here, MROH6 is linked to breast carcinoma.
