Furthermore, we analyzed the expression status of TMEM65 in TNBC in three publicly available datasets, including TCGA, CPTAC, and CBCGA.[27] Consistently, both protein and RNA levels of TMEM65 were upregulated in TNBC tissues, and their expression levels were higher in TNBC relative to luminal‐ and HER2‐positive subtypes of breast cancer (Figure 1H–L). Here, ERBB2 is linked to breast cancer.
