Supplementary Figure S1 - S8 from The Master Neural Transcription Factor BRN2 Is an Androgen Receptor–Suppressed Driver of Neuroendocrine Differentiation in Prostate Cancer

Supplementary Figure S1. Generation of ENZR Xenografts and Cell Lines. Supplementary Figure S2. AR non-driven ENZR cells display a NE differentiation signature. Supplementary Figure S3. BRN2 expression is associated with PCa progression and a NE phenotype in human tumors. Supplementary Figure S4. BRN2 expression is inversely related to AR activity and is required for ENZ-induced NE marker expression in CRPC. Supplementary Figure S5. BRN2 overexpression induces NE marker expression and reciprocally regulates AR. Supplementary Figure S6. BRN2 activity and markers of NE differentiation are suppressed by androgens in CRPC and ENZR cells. Supplementary Figure S7. SOX2 expression is induced by ENZ and suppressed by androgens. Supplementary Figure S8. BRN2 is required for neuroendocrine marker expression and aggressive growth of CRPC cells in vitro.
