OVOL3 and breast carcinoma: A dataset from 51 breast cancer cell lines revealed that OVOL1 mRNA levels were downregulated in cell lines classified into an aggressive basal subtype, compared with those cell lines grouped into a less aggressive luminal subtype (Supplementary Fig. 1a).37 However, no difference of OVOL2 and OVOL3 expression between these two subgroups was observed (Supplementary Fig. 1a).
