For LumB, HER2E, and basal cancers we observed no significant change in total RIF1 mRNA expression between tumour and matched normal samples separated (Figure 2A), while for LumA cancers we observed a marginally significant drop in expression, consistent with there being no significant change in RIF1 expression when considering all breast cancers combined (Figure 1C). Here, RIF1 is linked to breast carcinoma.
