Our bioinformatics analysis from the bc-GenExMiner database demonstrated a lower expression of PLA2R1 mRNA in basal-like, human epidermal growth factor receptor 2 (HER2)-positive and luminal B breast cancers in comparison to both luminal A and normal breast-like cancers (p < 0.0001) (Figure 2A,B) [15]. Here, PLA2R1 is linked to breast cancer.
