HJURP had a very detrimental role in breast cancer (GSE1456: OS, n = 159, HR = 1.77, Cox p = 0.001678; GSE2034: DMFS, n = 286, HR = 1.51, Cox p = 0.011628; GSE9195: RFS, n = 77, HR = 4.63, Cox p = 0.002148; GSE11121: DMFS, n = 200, HR = 2.24, Cox p = 0.001154; GSE12276: RFS, HR = 1.39, Cox p = 0.001701). This evidence concerns the gene HJURP and breast cancer.
