PTEN and cancer: Among the down-regulated RNAs, we identified several cancer-related transcripts, such as: fibroblast growth factor 4 (FGF4); fibroblast growth factor 21 (FGF21); leptin (LEP), Claudin 17 (CLDN17); cadherin 9 (CDH9) Tumor Necrosis Factor receptor (TNFRSF11B); BCL2-associated X (BAX); Tumor protein p53 (TP53) and Phosphatase and tensin homolog (PTEN) (see Table 2).
