Examples of signaling cascades activated by ligand-activated hormone receptors that impinge on epigenetic regulators, altering gene expression to result in increased tumor susceptibility

Examples
Ligand17-β Estradiol, xenoestrogens (e.g., BPA, DES, Genistein)
Nuclear hormone receptorER, PR, AR, Ahr, PPARγ
Nongenomic signalingPI3K/AKT, PKA, MAPK, PLC/PKC, PKG, JAK/STAT, Pak1, casein kinase I-γ2, sphingosine kinase, CaMKIV, tyrosine kinase Src, p21ras, adenylyl cyclase, etc.
