Expression of RFX1 mRNA levels in tumor tissues about the relevance to the conventional biomarkers. Mean RFX1 mRNA levels in the ER positive BC subgroup were significantly higher than in the ER negative subgroup. The PgR positive patients' mean RFX1 mRNA levels was also significantly higher than that of PgR negative patients. The HER2 negative subgroup had a significantly higher mean RFX1 mRNA level than the HER2 positive subgroup. The triple-negative and non-triple-negative subgroups did not significantly differ. NS, not significant.
