| Study ID | ST002864 |
| Study Title | Metabolic profiling, glucose tracing and glutamine tracing in naive and Enzalutamide-treated 16D prostate cancer cells expressing RFP or MYC |
| Study Summary | Advanced prostate cancers are treated with therapies targeting the androgen receptor (AR) signaling pathway. While many tumors initially respond to AR inhibition, nearly all develop resistance. It is critical to understand how prostate tumor cells respond to AR inhibition in order to exploit therapy-induced phenotypes prior to the outgrowth of treatment-resistant disease. Here, we comprehensively characterize the effect of AR blockade on prostate cancer metabolism using transcriptomics, metabolomics and bioenergetics approaches. The metabolic response to AR inhibition is defined by reduced glycolysis, robust elongation of mitochondria, and increased reliance on mitochondrial oxidative metabolism. We establish DRP1 activity and MYC signaling as mediators of AR blockade-induced metabolic phenotypes. Rescuing DRP1 phosphorylation after AR inhibition restores mitochondrial fission, while rescuing MYC restores glycolytic activity and prevents sensitivity to complex I inhibition. Our study provides new insight into the regulation of treatment-induced metabolic phenotypes and vulnerabilities in prostate cancer. In the MS data, M0, M1, M2, M3,... represent isotopologues of each metabolite. |

Collection:
| Collection ID: | CO002969 |
| Collection Summary: | Media was aspirated and cells were washed with cold 150mM ammonium acetate pH 7.3. Metabolite extractions were performed by adding 500μl of cold 80% methanol containing 2nM Norvaline (Sigma) as an internal standard per well. Cells were removed using a cell scraper before transferring cell suspensions to 1.5ml Eppendorf tubes. Samples were vortexed for 30 seconds and spun at 4°C for 5 minutes at maximum speed to pellet the insoluble fraction before 420 µl of the soluble fraction was transferred to ABC vials (Thermo Fisher Scientific). 80% MeOH was evaporated from the ABC vials using the EZ-2Elite evaporator (Genevac) and samples were stored at -80°C until analysis. |
