Our study analyzed the TCGA dataset and found that TROAP mRNA expression was significantly increased in BC tumor tissues (Figure 1(a); N, noncancerous; T, tumor; P<0.001) and in all molecular subtypes of BC (basal-like, HER2 overexpressed, luminal A and luminal B; Figure 1(b); P<0.001). The gene discussed is TROAP; the disease is neoplasm.
