FNDC1 and breast cancer: In addition, high expression of FNDC1 (probe 226930_at, p = 0.019) and the low expression of PDIA3 (probe 227033_at, p = 0.0037), HSPA5 (probe 230031_at, p = 0.0024) and CANX (probe 238034_at, p = 0.0013) were also associated with a worse overall survival in breast cancer patients (Figure 4).
