This revealed that both EPI (e.g. LLGL2, CLDN4, KRT7, ST14) and MES (e.g. SNAI1, VIM, AP1M1) genes positively correlated with PIEZO1 expression across all quintiles, whilst markers of luminal breast tumors (ESR1, FOXA1, PGR) negatively correlated in all instances. Here, CLDN4 is linked to breast neoplasm.
