Among the groups of patients divided into four subtypes, triple negative (TN) breast cancer which was negative for these three receptors resulted in the lowest survival rate (Figure 1I) and the expression level of ST14/Prss14 was the highest (TN vs. luminal A, P < 0.001, TN vs. luminal B, P < 0.0001, TN vs. HER2, P > 0.05, Figure 1J). The gene discussed is ST14; the disease is breast cancer.
