Immunohistochemistry revealed a significant decrease in expression of FASN and ACC1 proteins in prostate adenocarcinoma sections of SFN-treated TRAMP mice when compared with controls.
Using immunohistochemistry and fluorescence in situ hybridization analysis in paraffin-embedded tissue microarrays, we observed gene copy gain in 24% of all prostate adenocarcinoma specimens examined with concurrent increased FASN protein expression.
We used immortalized human prostate epithelial cells (iPrECs), androgen receptor-overexpressing iPrECs (AR-iPrEC), and human prostate adenocarcinoma LNCaP cells that stably overexpressed FASN for cell proliferation assays, soft agar assays, and tests of tumor formation in immunodeficient mice.
