#METABOLOMICS WORKBENCH juliehaines_20240918_073253 DATATRACK_ID:5206 STUDY_ID:ST003491 ANALYSIS_ID:AN005731 PROJECT_ID:PR002140 VERSION 1 CREATED_ON September 18, 2024, 7:22 pm #PROJECT PR:PROJECT_TITLE Blocking tryptophan catabolism reduces triple-negative breast cancer invasive PR:PROJECT_TITLE capacity PR:PROJECT_SUMMARY Anchorage-independent triple-negative breast cancer (TNBC) cells exhibit PR:PROJECT_SUMMARY elevated levels of the tryptophan (TRP) catabolizing enzyme tryptophan PR:PROJECT_SUMMARY 2,3-dioxygenase 2 (TDO2) compared to the same cells grown in two-dimensional PR:PROJECT_SUMMARY culture. Tracing of 13C11-TRP demonstrated that anchorage-independent culture PR:PROJECT_SUMMARY and/or inflammatory cytokines that activate nuclear factor PR:PROJECT_SUMMARY kappa-light-chain-enhancer of activated B (NFκB) increase TRP catabolism and PR:PROJECT_SUMMARY production of downstream catabolites such as kynurenine (KYN), which activate PR:PROJECT_SUMMARY the aryl hydrocarbon receptor (AhR). TDO2 expression is heterogeneous within PR:PROJECT_SUMMARY TNBC cell lines. To determine the function of TDO2, both pharmacologic PR:PROJECT_SUMMARY inhibition and genetic manipulation were conducted. TDO2 knockdown revealed a PR:PROJECT_SUMMARY compensatory increase in indoleamine 2,3-dioxygenase 1 (IDO1), a non-homologous PR:PROJECT_SUMMARY TRP catabolizing enzyme, indicating that dual inhibition of these two enzymes is PR:PROJECT_SUMMARY necessary to reliably block TRP catabolism. Thus, we tested a newly developed PR:PROJECT_SUMMARY TDO2/IDO1 dual inhibitor, AT-0174, and found that it effectively inhibits TNBC PR:PROJECT_SUMMARY TRP catabolism. Furthermore, AT-0174 treatment or AhR inhibitor significantly PR:PROJECT_SUMMARY decreased TNBC anchorage-independent survival, invasive capacity, and expression PR:PROJECT_SUMMARY of mesenchymal genes and protein, while exogenous KYN increased invasion through PR:PROJECT_SUMMARY AhR-mediated ZEB1 expression. Thus, dual inhibition of TDO2/IDO1 may prove PR:PROJECT_SUMMARY efficacious against TNBC progression.

The resulting supernatants were collected and CO:COLLECTION_SUMMARY frozen at -80 ℃. CO:SAMPLE_TYPE Culture Media #TREATMENT TR:TREATMENT_SUMMARY TNBC cell line SUM159 with stable TDO2 overexpression (TDO2 OE) were cultured TR:TREATMENT_SUMMARY relative to empty vector (EV). Culture media was not changed during the duration TR:TREATMENT_SUMMARY of the experiments. #SAMPLEPREP SP:SAMPLEPREP_SUMMARY Supernatant aliquots were thawed on ice then 20 uL was treated with 480 uL of SP:SAMPLEPREP_SUMMARY ice cold 5:3:2 methanol:acetonitrile:water (v/v/v). Samples were vortexed 30 min SP:SAMPLEPREP_SUMMARY at 4 degrees C followed by centrifugation for 10 min at 18,000 g. Aliquots of SP:SAMPLEPREP_SUMMARY supernatant (50 uL) were dried using a speedvac then reconstituted in an SP:SAMPLEPREP_SUMMARY equivalent volume of 0.1% formic acid. Samples were maintained at 4°C until SP:SAMPLEPREP_SUMMARY analysis that same day.
