ERBB2 and breast carcinoma: Although we found HJURP mRNA levels were not associated with ERBB2 status, the mRNA levels of HJURP was still found significantly higher in triple-negative (ER negative, PR negative, ERBB2/HER2/neu not overexpressed) breast cancer, possibly due to the fact that a higher HJURP mRNA level is significantly associated with ER or PR negative status.
