MDA‐MB‐231 is a p53 mutant cell line while MCF‐7 cells retain functional p53,64 whereas basal STAT3 phosphorylation level is comparably higher in TNBC cells (eg, MDA‐MB‐231 or MDA‐MB‐468) as compared with luminal‐type (eg, MCF‐7) or HER2‐positive (eg, BT474) breast cancer cells.65 We noted that lovastatin‐reduced cell viability is accompanied by survivin reduction (Figure S2) and STAT3 dephosphorylation (Figure S3) in MDA‐MB‐231 and MDA‐MB‐468 cells. Here, TP53 is linked to breast carcinoma.
