    Title: Aspalathus linearis suppresses AKT signaling, c-Myc, AR and survival of enzalutamide-resistant prostate cancer cells

    Abstract: Enzalutamide, a nonsteroidal antiandrogen, significantly prolonged the survival of patient with metastatic castration-resistant prostate cancer (CRPC). However, patients receiving enzalutamide frequently develop drug resistance within 1-2 years. Rooibos (Aspalathus linearis) is a shrub-like leguminous fynbos plant endemic to the Cedarberg Mountains area in South Africa. We examined if GRT may suppress the enzalutamide-resistant LNCaP C4-2 MDV3100r cells. GRT dose-dependently suppressed the proliferation, colony formation, cell cycle progression as well as induced apoptosis in MDV3100r cells. GRT suppressed the protein expression level of Akt, PI3Kα, PI3Kγ, PDK1, phospho-PDK1 S241, Skp2, cyclin D1, AR, phos-pho-AR S81, Cdk1, pro-PARP, cMyc and Bcl-2 but increased abundance of caspase 3 and cleaved-PARP. GRT reduced the abundance of AR proteins both in nucleus and cytoplasm of MDV3100r cells. Overexpression of AKT and c-Myc partially antagonized the suppressive effects of GRT Our study suggested that GRT may be useful for preventing enzalutamide resistance.
