AKT1 and breast neoplasm: For example, among eight pathways that were shown to play roles in breast tumor metastasis (Krishnan et al., 2013), we found that five of them are significantly enriched for ER- 3′US ceRNA partners with the exception of PI3K/AKT, the enriched p-value of which is just below the significance cutoff (P = 10−1.95).
