KNSTRN and breast carcinoma: The highest and lowest expression of KNSTRN were in TNBC and luminal type breast cancers, respectively (p < 0.05, Fig. 2E), and was significantly elevated in both infiltrating ductal carcinomas (p < 0.001, Fig. 2F) and patients who died (p < 0.027, Fig. 2G), suggesting that high expression of KNSTRN contributed to the malignant transformation of breast cancers.
