Further, low GATA3 was strongly associated with the cholesterol synthesis precursor enzyme 3‐hydroxy‐3‐methylglutaryl‐CoA synthase 1 (HMGCS1) (p < 0.001; supplementary material, Figure S5D), suggested to contribute to dysregulated mevalonate metabolism and stemness in BC models [50]. Here, GATA3 is linked to breast cancer.
