According to Lin et al.'s study, LINK‐A expression levels were much higher in 2 stage‐III TNBC tissues than in their paired adjacent non‐cancer breast tissues, ERPR+/HER2+, HER2‐/ERPR+ and ERPR−/HER2+ breast cancer tissues, suggesting the close association between TNBC and LINK‐A expressions 18. The gene discussed is ERBB2; the disease is breast cancer.
