BRCA1 and breast cancer: After exclusion of two cell lines (BT-483 and HCC1143, indicated by red dots in the left plot of Figure 8C) identified to have a poor correlation, the remaining 29 BC lines showed a positive correlation between BRCA1 and miR-129-5p (correlation coefficiency = 0.4364 ± 0.2120) in a statistically significant manner (p = 0.0493) (Figure 8C, the right plot).
