| Study Title | FDX2-KO induces global down-regulation of iron-sulfur cluster-containing proteins and senescence-like growth arrest or death in ovarian cancer cells |
| Study Summary | Recent studies report molecular mechanisms underlying iron-sulfur cluster (Fe-S) biosynthesis and suggest its importance in health and disease. However, a role for Fe-S biosynthesis in cancer contexts remains unclear. Here we report that FDX2, an Fe-S assembly factor, is indispensable for maintenance of cellular Fe-S-containing proteins (Fe-S protein(s)) and proliferation of ovarian cancer (OVC) cells. CRISPR-screening of all metabolism-related genes in OVC cells identified several Fe-S assembly genes as essential for OVC growth. Using an inducible FDX2-KO OVC line, we found that FDX2 loss promotes either senescence-like growth arrest or cell death, depending on TP53 status. Mechanistically, FDX2-loss caused global but differential post transcriptional down-regulation of Fe-S proteins, in turn perturbing respiration, iron-regulation and redox homeostasis, all associated with DNA damage. These results demonstrate significant roles for Fe-S biosynthesis in OVC proliferation and survival and provide information about how the cellular Fe-S-protein network responds to disruptions in Fe-S assembly. |

Collection:
| Collection ID: | CO003380 |
| Collection Summary: | Cells were maintained in DMEM medium (high glucose) in the presence of doxycycline (DOX). For metabolome analysis, cells were seeded to new dishes at day 0 and cultured in the presence or absence of Dox for 4 days. At day 4, cells were replenished with fresh medium (with or without Dox) and cultured for additional one day. At day 5, cells were washed with PBS twice and detached from dishes using cell scraper into PBS. The detached cells were collected by centrifugation, snap-frozen by liquid nitrogen, and stored at -80 oC until metabolite extraction. |

Treatment:
| Treatment ID: | TR003396 |
| Treatment Summary: | FDX2-iKO JHOC5 cells were cultured 5 days with or without doxycycline (30 ng/ml) and collected. Metabolome data were normalized to protein amounts of cells (shown in "Study design") used for the metabolite extraction. |
Sample Preparation:
| Sampleprep ID: | SP003394 |
| Sampleprep Summary: | The cell extracts were centrifugally concentrated for 2.5 hours using a LABCONCO centrifugal concentrator with cooling function (LABCONCO corporation). |
