Additionally, we found a significant correlation between PBOV1 and C/EBPδ expression levels in GOBO pooled breast cancer dataset [34] (Pearson correlation 0.14, p = 5•10−6, 8th percentile)and between PBOV1 and C/EBPγ in Neve et al. [41] breast cancer cell line dataset (correlation 0.502, p = 5•10−8, 2nd percentile). Here, PBOV1 is linked to breast carcinoma.
