A comparison of the pairwise expression levels between miR-155-5p and mRNA BRCA1 within WBCs for each patient and carrier revealed a significant negative correlation (p = 0.0001 and p = 0.034) (Figure 7A,B) for patients with breast and ovarian cancer, respectively, with marginal significance (p = 0.055) for the carriers (Figure 7C), which was not the case for controls. Here, BRCA1 is linked to ovarian carcinoma.
