The results from the in vitro and in vivo experiments demonstrated that the ethanol extract of Davallia formosana can suppress proliferation, migration, and invasion in PCa cells by inhibiting the levels of SREBP-1, FASN, AR, and PSA, suggesting that SREBP-1/FASN/lipogenesis and the AR axis could be potential targets for the treatment of PCa (173). The gene discussed is AR; the disease is posterior cortical atrophy.
