Molecular Pathways: Fatty Acid Synthase
Clin Cancer Res 2015 Dec 15;21(24):5434-8.PMID:26519059DOI:10.1158/1078-0432.CCR-15-0126.
Therapies that target tumor metabolism represent a new horizon in anticancer therapies. In particular, cancer cells are dependent on the generation of lipids, which are essential for cell membrane synthesis, modification of proteins, and localization of many oncogenic signal transduction enzymes. Because fatty acids are the building blocks of these important lipids, fatty acid synthase (FASN) emerges as a unique oncologic target. FASN inhibitors are being studied preclinically and beginning to transition to first-in-human trials. Early generation FASN inhibitors have been studied preclinically but were limited by their pharmacologic properties and side-effect profiles. A new generation of molecules, including GSK2194069, JNJ-54302833, IPI-9119, and TVB-2640, are in development, but only TVB-2640 has moved into the clinic. FASN inhibition, either alone or in combination, holds promise as a novel therapeutic approach for patients with cancer.
Inhibition of de novo lipogenesis targets androgen receptor signaling in castration-resistant prostate cancer
Proc Natl Acad Sci U S A 2019 Jan 8;116(2):631-640.PMID:30578319DOI:10.1073/pnas.1808834116.
A hallmark of prostate cancer progression is dysregulation of lipid metabolism via overexpression of fatty acid synthase (FASN), a key enzyme in de novo fatty acid synthesis. Metastatic castration-resistant prostate cancer (mCRPC) develops resistance to inhibitors of androgen receptor (AR) signaling through a variety of mechanisms, including the emergence of the constitutively active AR variant V7 (AR-V7). Here, we developed an FASN inhibitor (IPI-9119) and demonstrated that selective FASN inhibition antagonizes CRPC growth through metabolic reprogramming and results in reduced protein expression and transcriptional activity of both full-length AR (AR-FL) and AR-V7. Activation of the reticulum endoplasmic stress response resulting in reduced protein synthesis was involved in IPI-9119-mediated inhibition of the AR pathway. In vivo, IPI-9119 reduced growth of AR-V7-driven CRPC xenografts and human mCRPC-derived organoids and enhanced the efficacy of enzalutamide in CRPC cells. In human mCRPC, both FASN and AR-FL were detected in 87% of metastases. AR-V7 was found in 39% of bone metastases and consistently coexpressed with FASN. In patients treated with enzalutamide and/or abiraterone FASN/AR-V7 double-positive metastases were found in 77% of cases. These findings provide a compelling rationale for the use of FASN inhibitors in mCRPCs, including those overexpressing AR-V7.
